Robots, employment and the mis-measurement of productivity

  • UK productivity – output/hour has risen 1.5% in a decade
  • UK unemployment, at 4.2%, is the lowest since April 1975
  • UK real-wages have risen by 1.1% per annum over the last four years
  • Robots may be coming but it’s not showing up in the data

The subject matter of this Macro Letter is broad, so I shall confine my investigation to the UK. It was, after all, one of the first countries where services became a larger percentage of GDP than manufacturing. The crossover between manufacturing and services is estimated to have happened around 1881. When Napoleon Bonaparte described England as, ‘A nation of shopkeepers,’ his intension may have been derisive, but his observation was prescient. Of course, M. Bonaparte was actually quoting Adam Smith, who first coined the phrase in his magnum opus, An Inquiry into the Nature and Causes of the Wealth of Nations, published in 1776: now, he really was prescient.

As we stare into the abyss, anticipating the huge percentage of manufacturing – and now, many services – jobs which are expected to be replaced by machines, it behoves us to begin by reviewing the accuracy with which we measure services in general. A recent paper from the Centre for Economic and Business Research does just that for one sub-sector, although it suggests that mis-measurement of economic activity in services, always difficult to define, may be a factor in the poor productivity record of the UK. I have often described Britain as a post-industrial nation but this research, into one of the most vibrant corners of the economy, makes fascinating reading – The True Value of Creative Industries Digital Exports – CIC, CBER – March 2018 – finds, among other things that: –

The UK’s creative industries exports are: –

£46bn in goods and services – 24% higher than the official figure

£31bn of total creative exports are services – 41% higher than the official figure

£21bn of these creative services are digital services – 40% higher than the official figure

The CEBR goes on to point out other weaknesses in current measurements of economic activity: –

…estimated official figures for 2016 highlight that the majority of creative industries sub-sectors are exporting digital services. The IT, software and computer services sector, for example, exports £8.95bn in digital services. However, according to these figures, the crafts and museums, galleries and libraries sectors’ digital services exports are zero – which we know is not the case.

Many UK YouTube channels, for example, are watched by millions of viewers across the world. It is through these types of platforms that the creative industries export audiovisual content, music, and tutorials. Such platforms and the content they offer, however, may not be registered as a service export. This is due to difficulties capturing data for business models such as those offering free content and based on advertising revenues.

There are also structural challenges with collecting data on such exports. Often, it is difficult for digital intermediaries to determine the point of sale and purchase. The borderless way in which many global firms operate presents additional complications and the origin of the creative content, and of those who consume it, is frequently hard to track.

This brings me to the vexed question of productivity growth in the new machine age. In the Deloitte – Monday Briefing – Thoughts on the global economy – from 30th April, the author reflects on the discussions which occurred at the annual global gathering of Deliotte’s economic experts. I’m cherry picking, of course, the whole article is well worth reading: –

Despite discussion of recession risks I was struck by a cautious optimism about the long-term outlook. There was a general view that the slowdown in productivity growth in the West has been overstated, partly because of problems in capturing gains from technological change and quality improvements. As a result most of us felt that Western economies should be able to improve upon the lacklustre growth rates seen in the last ten years.

We agreed too that apocalyptic media stories about new technologies destroying work were overcooked; technology would continue to create more jobs than it destroys. The challenge would be to provide people with the right skills to prosper. The question was, what skills? We had a show of hands on what we would recommend as the ideal degree subjects for an 18-year-old planning for a 40-year career. Two-thirds advocated STEM subjects, so science, technology, engineering and maths. A third, myself included, opted for humanities/liberal arts as a way of honing skills of expression, creativity and thinking.

Mr Stewart ends by referring to a letter to the FT from Dr Lawrence Haar, Associate Professor at the University of Lincoln, in which he argues that poor UK productivity is a function of the low levels of UK unemployment. In other words, when everyone, even unproductive workers, are employed, productivity inevitably declines:-

…it does not have to be this way. Some economies, including Singapore, Switzerland and Germany, combine low unemployment and decent productivity growth. The right training and education can raise productivity rates for lower skilled workers. 

This theme of productivity growth supported by the right education and training is at the heart of a recent paper written by Professor Shackleton of the IEA – Current Controversies No. 62 – Robocalypse Now? IEA – May 2018 – the essay cautions against the imposition of robotaxes and makes the observation that technology has always created new jobs, despite the human tendency to fear the unknown: why should the adoption of a new swath of technologies be different this time? Here is his introduction: –

It is claimed that robots, algorithms and artificial intelligence are going to destroy jobs on an unprecedented scale.

These developments, unlike past bouts of technical change, threaten rapidly to affect even highly-skilled work and lead to mass unemployment and/or dramatic falls in wages and living standards, while accentuating inequality.

As a result, we are threatened with the ‘end of work’, and should introduce radical new policies such as a robot tax and a universal basic income.

However the claims being made of massive job loss are based on highly contentious technological assumptions and are contested by economists who point to flaws in the methodology.

In any case, ‘technological determinism’ ignores the engineering, economic, social and regulatory barriers to adoption of many theoretically possible innovations. And even successful innovations are likely to take longer to materialise than optimists hope and pessimists fear.

Moreover history strongly suggests that jobs destroyed by technical change will be replaced by new jobs complementary to these technologies – or else in unrelated areas as spending power is released by falling prices. Current evidence on new types of job opportunity supports this suggestion.

The UK labour market is currently in a healthy state and there is little evidence that technology is having a strongly negative effect on total employment. The problem at the moment may be a shortage of key types of labour rather than a shortage of work.

The proposal for a robot tax is ill-judged. Defining what is a robot is next to impossible, and concerns over slow productivity growth anyway suggest we should be investing more in automation rather than less. Even if a workable robot tax could be devised, it would essentially duplicate the effects, and problems, of corporation tax.

Universal basic income is a concept with a long history. Despite its appeal, it would be costly to introduce, could have negative effects on work incentives, and would give governments dangerous powers.

Politicians already seem tempted to move in the direction of these untested policies. They would be foolish to do so. If technological change were to create major problems in the future, there are less problematic policies available to mitigate its effects – such as reducing taxes on employment income, or substantially deregulating the labour market.

Professor Shackleton provides a brief history of technological paranoia. Riccardo added a chapter entitled ‘On Machinery’ to the third edition of his ‘Principles of Political Economy and Taxation,’ stating: –

‘I am convinced that the substitution of machinery for human labour is often very injurious to the interests of the class of labourers’.

While Marx, writing only a few decades later, envisaged a time when man would be enabled to: –

‘…to hunt in the morning, fish in the afternoon, rear cattle in the evening, criticise after dinner… without ever becoming hunter, fisherman, herdsman or critic.’

As for Keynes essay on the, ‘Economic Possibilities for our Grandchildren’, his optimism is laudable if laughable – 15 hour working week anyone?

The paranoia continues, nonetheless – The Economist – A study finds nearly half of jobs are vulnerable to automation – April 2018 – takes up the story:-

A wave of automation anxiety has hit the West. Just try typing “Will machines…” into Google. An algorithm offers to complete the sentence with differing degrees of disquiet: “…take my job?”; “…take all jobs?”; “…replace humans?”; “…take over the world?”

Job-grabbing robots are no longer science fiction. In 2013 Carl Benedikt Frey and Michael Osborne of Oxford University used—what else?—a machine-learning algorithm to assess how easily 702 different kinds of job in America could be automated. They concluded that fully 47% could be done by machines “over the next decade or two”.

A new working paper by the OECD, a club of mostly rich countries, employs a similar approach, looking at other developed economies. Its technique differs from Mr Frey and Mr Osborne’s study by assessing the automatability of each task within a given job, based on a survey of skills in 2015. Overall, the study finds that 14% of jobs across 32 countries are highly vulnerable, defined as having at least a 70% chance of automation. A further 32% were slightly less imperilled, with a probability between 50% and 70%. At current employment rates, that puts 210m jobs at risk across the 32 countries in the study.

For a robust analysis, if not refutation, of the findings of Frey and Osborne, I refer you back to Professor Shackleton’s IEA paper. He is more favourably disposed towards the OECD research, which is less apocalyptic in its conclusions. He goes on to find considered counsel in last year’s report from McKinsey Global Institute (2017) A Future that Works: Automation Employment and Productivity.

The IEA paper highlights another factor which makes it difficult to assess the net impact of technological progress, namely, the constantly changing nature of the labour market. As the table below reveals it has hardly been in stasis since the turn of the millennium: –

The job losses are broadly predictable; that technology has usurped the role of the travel agent is evident to anyone who booked a flight, hotel or hire-car online recently.  For economists there are always challenges in capturing the gains; back in 1987 Robert Solow, a recipient of the Nobel prize from economics,  famously observed, ‘You can see the computer age everywhere but in the productivity statistics’ – perhaps the technology has been creating more jobs than thought. Does the 170% rise in Animal Care and Control owe a debt to technology? You might be inclined to doubt it but the 400,000 Uber drivers of London probably do. We are still seeking signs in the economic data for something we know instinctively should be evident.

Between the mis-measurement of economic activity (if technology is being under-estimated to the tune of 24% in the creative industries sector to what extent are productivity gains from technology being underestimated elsewhere?) and the ever changing employment landscape, I believe the human race will continue to be employed in a wide and varied range of increasingly diverse roles. If some of the more repetitive and less satisfying jobs are consigned to robots and machine learning computer code, so much the better for mankind. For more on, what is sometimes termed, the routinisation of work, this working paper from Bruegel – The impact of industrial robots on EU employment and wages: A local labour market approach – April 2018 is inciteful. They examine six EU countries and make comparisons, or highlighting contrasts, with the patterns observed in the US. Their conclusions are somewhat vague, however, which appears to be a function of the difficulty of measurement: –

We only find mixed results for the impact of industrial robots on wage growth, even after accounting for potential endogeneity and potential offsetting effects across different population or sectoral groups.

…We believe that future research on the topic should focus on exploiting more granular data, to explore whether insignificant aggregate effects (on wages) are to the result of counterbalancing developments happening at the firm level.

Bruegel refrain from proposing cuts to personal taxation as favoured by the IEA, suggesting that a more complex policy response may be required, however, their conclusions are only marginally negative. I am inclined to hope that market forces may be allowed to deal with the majority of the adjustment; they have worked well if history is any guide.

Conclusions and investment opportunities

Ignoring the fact that we are nine years into an equity bull market and that interest rates are now rising from their lowest levels ever recorded, the long term potential for technology remains supportive for equity markets, for earnings growth and for productivity. If history repeats, or even if it simply rhymes, it should also be good for employment.

With interest rates looking more likely to rise than fall over the next few years, companies will remain reticent to invest in capital projects. Buying back stock and issuing the occasional special dividend will remain the policy du jour. Assuming we do not suffer a repeat of the great financial recession of 2008 – and that remains a distinct possibility – the boon of technology will create employment with one invisible hand as it creatively destroys it with the other (with apologies to Smith and Schumpeter). If governments can keep their budgets in check and resist the temptation to siphon off investment from the productive sectors of the economy (which, sadly, I doubt) then, in the long run, the capital investment required to create the employment opportunities of the future will materialise.

Is the US exporting a recession?

Macro Letter – No 96 – 04-05-2018

Is the US exporting a recession?

  • The Federal Reserve continue to raise rates as S&P earnings beat estimates
  • The ECB and BoJ maintain QE
  • Globally, corporations rely on US$ financing, nonetheless
  • Signs of a slowdown in growth are clearer outside the US

After last week’s ECB meeting, Mario Draghi gave the usual press conference. He confirmed the continuance of stimulus and mentioned the moderation in the rate of growth and below-target inflation. He also referred to the steady expansion in money supply. When it came to the Q&A he revealed rather more:-

It’s quite clear that since our last meeting, broadly all countries experienced, to different extents of course, some moderation in growth or some loss of momentum. When we look at the indicators that showed significant, sharp declines, we see that, first of all, the fact that all countries reported means that this loss of momentum is pretty broad across countries.

It’s also broad across sectors because when we look at the indicators, it’s both hard and soft survey-based indicators. Sharp declines were experienced by PMI, almost all sectors, in retail, sales, manufacturing, services, in construction. Then we had declines in industrial production, in capital goods production. The PMI in exports orders also declined. Also we had declines in national business and confidence indicators.

I quote this passage out of context because the entire answer was more nuanced. My reason? To highlight the difference between the situation in the EU and the US. In Europe, money supply (M3) is growing at 4.3% yet inflation (HICP) is a mere 1.3%. Meanwhile in the US, inflation (CPI) is running at 2.4% and money supply (M2) is hovering a fraction above 2%. Here is a chart of Eurozone M3 since 1999:-

The recent weakening of momentum is a concern, but the absolute level is consistent with a continued expansion.

Looked at over a rather longer time horizon, here is a chart of US M2 since 1900:-

M2 since 1900 - Hoisington

The letters A, B, C, D denote the only occasions, during the last 118 years, when a decline in the expansion (or, during the 1930’s, contraction) of M2 did not lead to a recession. 17 out of 21 is a quite compelling record.

Another concern for markets is the flatness of the US yield curve. Here is the 2yr – 10yr yield differential since 1990:-

US 2yr - 10yr Factset Mauldin

Source: Factset, Mauldin Economics

More importantly, for international borrowers, the 6-month LIBOR rate has risen by more than 60 basis points since the start of the year (from 1.8% to 2.5%) whilst 30yr Swap rates have increased by only 40 basis points (2.6% to 3%). The 10yr – 30yr Swap curve is now practically flat.

Also worthy of comment, as US Treasury yields have risen, the relationship between Bonds and Swaps has begun to normalise – 30yr T-Bond yields are only 40 basis points above their level of January and roughly at the same level as in the spring of last year. In April 2017 I wrote in Macro Letter – No 74 – US 30yr Swaps have yielded less than Treasuries since 2008 – does it matter?:-

Today the IRS market increasingly determines the cost of finance, during the next crisis IRS yields may rise or fall by substantially more than the same maturity of US T-bond, but that is because they are the most liquid instruments and are only indirectly supported by the Central Bank.

It looks like I may have to eat my words, here is the Bond vs Swap table revisited:-

Evolution_of_T-Bond_and_IRS_Spreads_-_investing_co_002

Source: Investing.com, Interestrateswaps.com, BBA

What is evident is that the Bond/Swap inversion in the longer maturities has closed substantially even as shorter maturity spreads have narrowed. Federal Reserve policy has been the dominate factor.

Why is it, however, that the effect of higher US rates is, seemingly, felt more poignantly in Europe than the US? Does this bring us back to protectionism? Perhaps, but in less contentious terms, the US has run a capital account surplus for many years. Outside the US investment is closely tied to LIBOR financing costs, these have remained higher, except in the longest maturities, and these rates have risen most precipitously this year. Looked at another way, the higher interest rate policies of the Federal Reserve, despite the continued largesse of other central banks, is exporting the next recession to the rest of the world.

I ended Macro Letter – No 74 back in April 2017 – saying:-

Meanwhile, although interest rates have risen from historic lows they remain far below their long run average. Pension funds and other long-term investors still require 7% or more in annualised returns in order to meet their liabilities. They are being forced to continuously increase their investment risk and many have chosen to use the swap market. The next crisis is likely to see an even more pronounced unravelling than in 2008/2009. The unravelling may not happen for some while but the stresses are likely to be focused on the IRS market.

One year on, cracks in the capital markets edifice are beginning to become more evident. GDP growth has started to rollover in the US, Eurozone and Japan. Yields are still relatively low but the absolute increase in rates for shorter maturities (e.g. the near doubling of US 2yr yields from 1.25% to 2.5% in a single year) is guaranteed to take its toll on corporate interest servicing costs. US capital markets are the envy of the world. They are deep and allow borrowers to finance far into the future. The rest of the world is forced to borrow at shorter tenors. A three basis point narrowing of 5yr spreads between Swaps and Bonds is hardly compensation for the near 1% increase in interest rates, or, put in starker terms, a 46% increase in absolute borrowing costs.

Conclusion and investment opportunities

How is the rise in borrowing costs impacting the US stock market? Volatility is back, but earnings are robust. Factset – S&P 500 Earnings Season Update: April 27, 2018 – described it thus:-

To date, 53% of the companies in the S&P 500 have reported actual results for Q1 2018. In terms of earnings, more companies are reporting actual EPS above estimates (79%) compared to the five-year average. If 79% is the final percentage for the quarter, it will mark the highest percentage of S&P 500 companies reporting actual EPS above estimates since FactSet began tracking this metric in Q3 2008. In aggregate, companies are reporting earnings that are 9.1% above the estimates, which is also above the five-year average. In terms of sales, more companies (74%) are reporting actual sales above estimates compared to the five-year average. In aggregate, companies are reporting sales that are 1.7% above estimates, which is also above the five-year average. If 1.7% is the final percentage for the quarter, it will mark the largest revenue surprise percentage since FactSet began tracking this metric in Q3 2008.

… The blended (combines actual results for companies that have reported and estimated results for companies that have yet to report), year-over-year earnings growth rate for the first quarter is 23.2% today, which is higher than the earnings growth rate of 18.5% last week. Positive earnings surprises reported by companies in multiple sectors (led by the Information Technology sector) were responsible for the increase in the earnings growth rate for the index during the past week. All 11 sectors are reporting year-over-year earnings growth. Nine sectors are reporting double-digit earnings growth, led by the Energy, Materials, Information Technology, and Financials sectors.

We are more than halfway through Q1 earnings (I’m writing this letter on Wednesday 2nd May). Results have generally been above forecast and now the Fed seems conscious that they must not be too hasty to reverse the effects of both zero rates and QE. Added to which, while US stocks have been languishing mid-range, European stocks have recently broken out of their recent ranges to the upside, despite discouraging economic data.

The US stock market looks less expensive than it did in January 2017, when I wrote Macro Letter – 68 – Equity valuation in a de-globalising world. Then I was looking for stock markets with a low correlation to the US: they were (and remain) hard to find.

Other indicators to watch which exert a strong influence on stocks include the US PMI Index – last at 54.8 up from 54.2 in March. Above 50 there is little cause for concern. For the Eurozone it is even higher at 55.2, whilst throughout G20 no economy is recording a PMI below 50.

The chart below shows the Citigroup Economic Surprises Index (blue) vs the S&P500 Forward P/E estimates (red):-

Economic surprises remain positive rather than negative for the US. In the Eurozone it is quite another matter:-

A number of economic indicators are pointing to a slowdown, yet US stocks are beating estimates. To judge from price action, the market appears to be unimpressed by earnings. I am reminded of the old adage, ‘When all the buyers are in the market it’s time to sell.’ From a technical perspective it makes sense to be patient, but the market has failed to rise substantially on a positive slew of earnings news. This may be because there is a more important factor driving sentiment: the direction of US rates. It certainly appears to have engendered a revival of the US$. It rallied last month having been in a downtrend since January 2017 despite a steadily tightening Federal Reserve. For EURUSD the move from 1.10 to 1.25 appears to have taken its toll. On the basis of the CESI chart, above, if Wall Street sneezes, the Eurozone might catch pneumonia.

Inflation or Employment

Inflation or Employment

Macro Letter – No 95 – 20-04-2018

Inflation or Employment

  • Inflationary fears are growing and US rates continue to rise
  • Employment has become more flexible since the crisis of 2008/2009
  • Commodity prices have risen but from multi-year lows
  • During the next recession job losses will rapidly temper inflationary pressures

Given the official policy response to the Great Financial Recession – a mixture of central bank balance sheet expansion, lower for longer interest rates and a general lack of fiscal rectitude on the part of developed nation governments – I believe there are two factors which are key for stock markets over the next few years, inflation and employment. The fact that these also happen to be the two mandated targets of the Federal Reserve – full employment and price stability – is more than coincidental. My struggle is in attempting to decide whether demand-pull inflation can survive the impact of a rapid rise in unemployment come the next recession.

Inflation and the Central Bankers response is clearly the new narrative of the financial markets. In his latest essay, Ben Hunt of Salient Partners makes some fascinating observations – Epsilon Theory: The Narrative Giveth and The Narrative Taketh Away:-

This market, like all markets, cares about two things and two things only — the price of money and the real return on invested capital. Or, as they are typically represented in cartoon form, interest rates and growth.

…This market, like all markets, needs a positive narrative on risk (the price of money) or reward (the real return on capital) to go up. Any narrative will do! But when neither risk nor reward is represented with a positive narrative, this market, like all markets, will go down. And that’s where we are today. 

Does the Fed have our back? No, they do not. They’ve told us and told us that they’re going to keep raising rates. And they will. The market still doesn’t fully believe them, and that’s going to be a constant source of market disappointment over the next few years. In the same way that markets go up as they climb a wall of worry, so do markets go down as they descend a wall of hope. The belief that central bankers care more about the stock market than the price stability of money is that wall of hope. It’s a forlorn hope.

The author goes on to discuss the way that inflation and the war on trade has derailed the global synchronized growth narrative. Dr Hunt writes at length about narratives; those who have been reading my letters for a while will know I regularly quote from his excellent Epsilon Theory.

The narrative has not yet become flesh, to coin a phrase, but in the author’s opinion it will:-

My view: the inflation narrative will surge again, as wage inflation is, in truth, not contained at all.

The trade war narrative hit markets in force in late February with the White House announcement on steel and aluminum tariffs. It subsided through mid-March as hope grew that Trump’s bark was worse than his bite, then resurfaced in late March with direct tariff threats against China, then subsided again on hopes that direct negotiations would contain the conflict, and has now resurfaced this past week with still more direct tariff threats against and from China. Already this weekend you’ve got Kudlow and other market missionaries trying to rekindle the hope of easy negotiations. But being “tough on trade” is a winning domestic political position for both Trump and Xi, and domestic politics ALWAYS trumps (no pun intended) international economics. 

My view: the trade war narrative will be spurred on by BOTH sides, and is, in truth, not contained at all.

The two charts below employ natural language processing techniques. They show how the inflation narrative has rapidly increased during the last 12 months. I shall leave Dr Hunt to elucidate:-

… analysis of a large set of market relevant articles — in this case everything Bloomberg has published that talks about inflation — where linguistic similarities create clusters of articles with similar meaning (essentially a linguistic “gravity model”), and where the dynamic relationships between and within these clusters can be measured over time.

epsilon-theory-the-narrative-giveth-and-the-narrative-taketh-away-april-10-2018-chart-one

Source: Quid.inc

What this chart shows is the clustering of content in 1,400 Bloomberg articles, which mention US inflation, between April 2016 and March 2017. The graduated colouring – blue earlier and red later in the year – enriches the analysis.

The next chart is for the period April 2017 to March 2018:-

epsilon-theory-the-narrative-giveth-and-the-narrative-taketh-away-april-10-2018-chart-two

Source: Quid.Inc

During this period there were 2,400 articles (a 75% increase) but, of more relevance is the dramatic increase in clustering.

What is clear from these charts is the rising importance of inflation as a potential driver of market direction. Yet there are contrary signals that suggest that economic and employment growth are already beginning to weaken. Can inflation continue to rise in the face of these headwinds. Writing in The Telegraph, Ambrose Evans-Pritchard has his doubts (this transcript is care of Mauldin Economics) – JP Morgan fears Fed “policy mistake” as US yield curve inverts:-

US jobs growth fizzled to stall-speed levels of 103,000 in March. The worldwide PMI gauge of manufacturing and services has dropped to a 14-month low. The average “Nowcast” tracker of global growth has slid suddenly to a quarterly rate of 3.2pc from 4.1pc as recently as early February.

Analysts at JP Morgan say the forward curve for the one-month Overnight Index Swap rate (OIS) – a market proxy for the Fed policy rate – has flattened and “inverted” two years ahead. This is a collective bet by big institutional investors and fund managers that interest rates may be falling by then.

…The OIS yield curve has inverted three times over the last two decades. In 1998 it proved to be a false alarm because the Greenspan Fed did a pirouette and flooded the system with liquidity. In 2000 it was a clear precursor of recession. In 2005 it signaled that the US housing boom was already starting to deflate.

…Growth of the “broad” M3 money supply in the US has slowed to a 2pc rate over the last three months (annualised)…pointing to a “growth recession” by early 2019. Narrow real M1 money has actually contracted slightly since November.

…RBC Capital Markets says this will drain M3 money by roughly $300bn a year…

…Three-month Libor rates – used to set the cost of borrowing on $9 trillion of US and global loans, and $200 trillion of derivatives – have surged 60 basis points since January.

…The signs of a slowdown are even clearer in Europe…Citigroup’s economic surprise index for the region has seen the worst four-month deterioration since 2008.  A reduction in the pace of QE from $80bn to $30bn a month has removed a key prop. The European Central Bank’s bond purchase programme expires altogether in September.

…The global money supply has been slowing since last September. The Baltic Dry Index measuring freight rates for dry goods peaked in mid-December and has since dropped 45pc.

Which brings us neatly to the commodity markets. Are real assets a safe place to hide in the coming inflationary (or perhaps stagflationary) environment? Will the lack of capital investment, resulting from the weakness in commodity prices following the financial crisis, feed through to cost-push inflation?

The trouble with commodities

Commodities are an excellent portfolio diversifier because they tend to be uncorrelated with stock, bonds or real estate. They have a weakness, however, since to invest in commodities one needs to accept that over the long run they have a negative real-expected return. Why? Because of man’s ingenuity. We improve our processes and invest in new technologies which reduce our production costs. We improve extraction techniques and enhance acreage yields. You cannot simply buy and hold commodities: they are trading assets.

Demand and supply of commodities globally is a complex challenge to measure; for grains, oilseeds and cotton the USDA World Agricultural Supply and Demand Estimates for March offers a fairly balanced picture:-

World 2017/18 wheat supplies increased this month by nearly 3.0 million tons as production is raised to a new record of 759.8 million

Global coarse grain production for 2017/18 is forecast 7.0 million tons lower than last month to 1,315.0 million

Global 2017/18 rice production is raised 1.2 million tons to a new record led by 0.3- million-ton increases each for Brazil, Burma, Pakistan, and the Philippines. Global rice exports are raised 0.8 million tons with a 0.3-million-ton increase for Thailand and 0.2- million-ton increases each for Burma, India, and Pakistan. Imports are raised 0.5 million tons for Indonesia and 0.3 million tons for Bangladesh. Global domestic use is reduced fractionally. With supplies increasing and total use decreasing, world ending stocks are raised 1.4 million tons to 144.4 million and are the second highest stocks on record.

Global oilseed production is lowered 5.7 million tons to 568.8 million, with a 6.1-million-ton reduction for soybean production and slightly higher projections for rapeseed, sunflower seed, copra, and palm kernel. Lower soybean production for Argentina, India, and Uruguay is partly offset by higher production for Brazil.

Cotton – Lower global beginning stocks this month result in lower projected 2017/18 ending stocks despite higher world production and lower consumption. World beginning stocks are 900,000 bales lower this month, largely attributable to historical revisions for Brazil and Australia. World production is about 250,000 bales higher as a larger Brazilian crop more than offsets a decline for Sudan. Consumption is about 400,000 bales lower as lower consumption in India, Indonesia, and some smaller countries more than offsets Vietnam’s increase. Ending stocks for 2017/18 are nearly 600,000 bales lower in total this month as reductions for Brazil, Sudan, the United States, and Australia more than offset an increase for Pakistan.

It is worth remembering that local market prices can be dramatically influenced by small changes in regional supply or demand and the vagaries of supply chain logistics. Added to which, for US grains there is heightened anxiety regarding tariffs: they are expected to be the main target of the Chinese retaliation.

Here is the price of US Wheat since 2007:-

Crisis? What crisis? It is still near to multi-year lows, although above the nadir of the financial crisis in 2009.

The broader CRB Index shows a more pronounced recovery, it has been rising since the beginning of 2016:-

Neither of these charts suggest that price momentum is that robust.

Another (and, perhaps, more global) measure of economic activity is the Baltic Dry Freight Index. This chart shows a very different reaction to the synchronised increase in world economic growth:-

In absolute terms the index has more than tripled in price from the 2016 low, nonetheless, it is still in the lower half of the range of the past decade.

Global economic growth may have encouraged a rebound in Copper, another industrial bellwether, but it appears to have lost some momentum of late:-

Brent Crude Oil also appears to be benefitting from the increase in economic activity. It has doubled from its low of two years ago. The US rig count has increased in response but at 800 it remains at half the level of a few years ago:-

US Natural Gas, which might still manage an upward price spike on account of the unseasonably cold weather in the US, provides a less compelling argument:-

Commodity markets are clearly off their multi-year lows, but the strength of momentum looks mixed and, in grains and oil seeds, global supply and demand look fairly balanced. Cost push inflation may be a factor in certain markets, but, without price-pull demand, inflation pressures are likely to be short-lived. Late cycle increases in commodity prices are quite common, however, so we may experience a short-run stagflationary squeeze on incomes.

Conclusions and investment opportunities

When ever I write about commodities in a collective way, I remind readers that each market is unique, pretending they are homogenous is often misleading. The recent rise in Cocoa, after a two-year downtrend resulting from an increase in global supply, is a classic example. The time it takes to grow a Cocoa plant governs the length of the cycle. Similarly, the lead time for producing a new ship is a major factor in determining the length of the freight rate cycle. Nonetheless, at the risk of contradicting myself, what may keep a bid under commodity markets is the low level of capital investment which has been a hall-mark of the long, listless recovery from the great financial recession. I believe an economic downturn is likely and job losses will occur rapidly in response.  

I entitled this letter ‘Inflation or Employment’, these are the factors which will dominate Central Bank policy. Currently commentators view inflation as the greater concern, as Dr Hunt’s research indicates, but I believe those Central Bankers who can (by which I mean the Federal Reserve) will attempt to insure they have raised interest rates to a level from which they can be cut, rather than having to rely on ever more unorthodox monetary policies.

What to expect from Central Bankers

  • The Federal Reserve continues to tighten and other Central Banks will follow
  • The BIS expects stocks to lose their lustre and bond yields to rise
  • The normalisation process will be protracted, like the QE it replaces
  • Macro prudential policy will have greater emphasis during the next boom

As financial markets adjust to a new, higher, level of volatility, it is worth considering what the Central Banks might be thinking longer term. Many commentators have been blaming geopolitical tensions for the recent fall in stocks, but the Central Banks, led by the Fed, have been signalling clearly for some while. The sudden change in the tempo of the stock market must have another root.

Whenever one considers the collective views of Central Banks it behoves one to consider the opinions of the Central Bankers bank, the BIS. In their Q4 review they discuss the paradox of a tightening Federal Reserve and the continued easing in US national financial conditions. BIS Quarterly Review – December 2017 – A paradoxical tightening?:-

Overall, global financial conditions paradoxically eased despite the persistent, if cautious, Fed tightening. Term spreads flattened in the US Treasury market, while other asset markets in the United States and elsewhere were buoyant…

Chicago Fed’s National Financial Conditions Index (NFCI) trended down to a 24-year trough, in line with several other gauges of financial conditions.

The authors go on to observe that the environment is more reminiscent of the mid-2000’s than the tightening cycle of 1994. Writing in December they attribute the lack of market reaction to the improved communications policies of the Federal Reserve – and, for that matter, other Central Banks. These policies of gradualism and predictability may have contributed to, what the BIS perceive to be, a paradoxical easing of monetary conditions despite the reversals of official accommodation and concomitant rise in interest rates.

This time, however, there appears to be a difference in attitude of market participants, which might pose risks later in this cycle:-

…while investors cut back on the margin debt supporting their equity positions in 1994, and stayed put in 2004, margin debt increased significantly over the last year.

At a global level it is worth remembering that whilst the Federal Reserve has ceased QE and now begun to shrink its balance sheet, elsewhere the expansion of Central Bank balance sheets continues with what might once have passed for gusto.

The BIS go on to assess stock market valuations, looking at P/E ratios, CAPE, dividend pay-outs and share buy-backs. By most of these measures stocks look expensive, however, not by all measures:-

Stock market valuations looked far less frothy when compared with bond yields. Over the last 50 years, the real one- and 10-year Treasury yields have fluctuated around the dividend yield. Having fallen close to 1% prior to the dotcom bust, the dividend yield has been steadily increasing since then, currently fluctuating around 2%. Meanwhile, since the GFC, real Treasury yields have fallen to levels much lower than the dividend yield, and indeed have usually been negative. This comparison would suggest that US stock prices were not particularly expensive when compared with Treasuries.

The authors conclude by observing that EM sovereign bonds in local currency are above their long-term average yields. This might support the argument that those stock markets are less vulnerable to a correction – I would be wary of jumping this conclusion, global stocks market correlation may have declined somewhat over the last couple of years but when markets fall hard they fall in tandem: correlations tend towards 100%:-

The BIS’s final conclusion?-

In spite of these considerations, bond investors remained sanguine. The MOVE* index suggested that US Treasury volatility was expected to be very low, while the flat swaption skew for the 10-year Treasury note denoted a low demand to hedge higher interest rate risks, even on the eve of the inception of the Fed’s balance sheet normalisation. That may leave investors ill-positioned to face unexpected increases in bond yields.

Had you read this on the day of publication you might have exited stocks before the January rally. As markets continue to vacillate wildly, there is still time to consider the implications.

Another BIS publication, from January, also caught my eye, it was the transcript of a speech by Claudio Borio’s – A blind spot in today’s macroeconomics? His opening remarks set the scene:-

We have got so used to it that we hardly notice it. It is the idea that, for all intents and purposes, when making sense of first-order macroeconomic outcomes we can treat the economy as if its output were a single good produced by a single firm. To be sure, economists have worked hard to accommodate variety in goods and services at various levels of aggregation. Moreover, just to mention two, the distinctions between tradeables and non-tradeables or, in some intellectual strands, between consumption and investment goods have a long and distinguished history. But much of the academic and policy debate among macroeconomists hardly goes beyond that, if at all.

The presumption that, as a first approximation, macroeconomics can treat the economy as if it produced a single good through a single firm has important implications. It implies that aggregate demand shortfalls, economic fluctuations and the longer-term evolution of productivity can be properly understood without reference to intersectoral and intrasectoral developments. That is, it implies that whether an economy produces more of one good rather than another or, indeed, whether one firm is more efficient than another in producing the same good are matters that can be safely ignored when examining macroeconomic outcomes. In other words, issues concerned with resource misallocations do not shed much light on the macroeconomy.

Borio goes on to suggest that ignoring the link between resource misallocations and macroeconomic outcomes is a dangerous blind spot in marcoeconomic thinking. Having touched on the problem of zombie firms he talks of a possible link between interest rates, resource misallocations and productivity.

The speaker reveals two key findings from BIS research; firstly that credit booms tend to undermine productivity growth and second, that the subsequent impact of the labour reallocations that occur during a financial boom last for much longer if a banking crisis follows. Productivity stagnates following a credit cycle bust and it can be protracted:-

Taking, say, a (synthetic) five-year credit boom and five postcrisis years together, the cumulative shortfall in productivity growth would amount to some 6 percentage points. Put differently, for the period 2008–13, we are talking about a loss of some 0.6 percentage points per year for the advanced economies that saw booms and crises. This is roughly equal to their actual average productivity growth during the same window.

Productivy stagnates - BIS

Borio’s conclusion is that different sectors of the economy expand and the contract with greater and lesser momentum, suggesting the need for more research in this area.

He then moves to investigate the interest rate productivity nexus, believing the theory that, over long enough periods, the real economy evolves independently of monetary policy and therefore that market interest rates converge to an equilibrium real interest rates, may be overly simplistic. Instead, Borio suggests that causality runs from interest rates to productivity; in other words, that interest rates during a cyclical boom may have pro-cyclical consequences for certain sectors, property in particular:-

During the expansion phase, low interest rates, especially if persistent, are likely to increase the cycle’s amplitude and length. After all, one way in which monetary policy operates is precisely by boosting credit, asset prices and risk-taking. Indeed, there is plenty of evidence to this effect. Moreover, the impact of low interest rates is unlikely to be uniform across the economy. Sectors naturally differ in their interest rate sensitivity. And so do firms within a given sector, depending on their need for external funds and ability to tap markets. For instance, the firms’ age, size and collateral availability matter. To the extent that low interest rates boost financial booms and induce resource shifts into sectors such as construction or finance, they will also influence the evolution of productivity, especially if a banking crisis follows. Since financial cycles can be quite long – up to 16 to 20 years – and their impact on productivity growth quite persistent, thinking of changes in interest rates (monetary policy) as “neutral” is not helpful over relevant policy horizons.

During the financial contraction, persistently low interest rates can contribute to this outcome (Borio (2014)). To be absolutely clear: low rates following a financial bust are welcome and necessary to stabilise the economy and prevent a downward spiral between the financial system and output. This is what the crisis management phase is all about. The question concerns the possible collateral damage of persistently and unusually low rates thereafter, when the priority is to repair balance sheets in the crisis resolution phase. Granted, low rates lighten borrowers’ heavy debt burden, especially when that debt is at variable rates or can be refinanced at no cost. But they may also slow down the necessary balance sheet repair.

Finally, Borio returns to the impact on zombie companies, whose number has risen as interest rates have fallen. Not only are these companies reducing productivity and economic growth in their own right, they are draining resources from the more productive new economy. If interest rates were set by market forces, zombies would fail and investment would flow to those companies that were inherently more profitable. Inevitably the author qualifies this observation:-

Now, the relationship could be purely coincidental. Possible factors, unrelated to interest rates as such, might help explain the observed relationship. One other possibility is reverse causality: weaker profitability, as productivity and economic activity decline in the aggregate, would tend to induce central banks to ease policy and reduce interest rates.

Among the conclusions reached by the Central Bankers bank, is that the full impact and repercussions of persistently low rates may not have been entirely anticipated. An admission that QE has been an experiment, the outcome of which remains unclear.

Conclusions and Investment Opportunities

These two articles give some indication of the thinking of Central Bankers globally. They suggest that the rise in bond yields and subsequent fall in equity markets was anticipated and will be tolerated, perhaps for longer than the market anticipate. It also suggests that Central Banks will attempt to use macro-prudential policies more extensively in future, to insure that speculative investment in the less productive areas of the economy do not crowd out investment in the more productive and productivity enhancing sectors. I see this policy shift taking the shape of credit controls and increases in capital requirements for certain forms of collateralised lending.

Whether notionally independent Central Banks will be able to achieve these aims in the face of pro-cyclical political pressure remains to be seen. A protracted period of readjustment is likely. A stock market crash will be met with liquidity and short term respite but the world’s leading Central Banks need to shrink their balance sheets and normalise interest rates. We have a long way to go. Well managed profitable companies, especially if they are not saddled with debt, will still provide opportunities, but stock indices may be on a sideways trajectory for several years while bond yields follow the direction of their respective Central Banks official rates.

Stocks for the Long Run but not the short

Macro Letter – No 93 – 23-03-2018

Stocks for the Long Run but not the short

  • In the long run stocks outperform bonds
  • For a decade stocks, bonds and real estate have risen in tandem
  • The risk of a substantial correction is high
  • Value-based equity investment is unfashionably enticing

The first part of the title of this Macro Letter is borrowed from an excellent book originally written in 1994. Among several observations made by the author, Jeremy Siegel, was the idea that stocks would at least keep pace with GDP growth or even exceed it at the national level. The data, which went back to the 19th Century, showed that stocks also outperformed bonds in the long-run. The price one has to pay for that outperformance is higher volatility than for bonds and occasional, possibly protracted, periods of under-performance or, if your portfolio is concentrated, the risk of default. This is not to say that bonds are exempt from default risk, notwithstanding the term ‘risk free rate’ which we associate with many government obligations. A diversified portfolio of stocks (and bonds) has been seen as the ideal investment approach ever since Markowitz promulgated the concept of modern portfolio theory.

Today, passive index tracking funds have swallowed a massive percentage of all the investment which flows into the stock market. Why? Because robust empirical data shows that it is almost impossible for active portfolio managers to consistently outperform their benchmark index in the long run once their higher fees have been factored in.

An interesting way of showing how indexation has propelled the stock market higher recently, regardless of valuation, is shown in this chart from Ben Hunt at Epsilon Theory – Three Body Problem. He uses it to show how the factor which is QE has trumped everything in its wake. I’ll allow Ben to explain:-

Here’s the impact of all that gravity on the Quality-of-Companies derivative investment strategy.

The green line below is the S&P 500 index. The white line below is a Quality Index sponsored by Deutsche Bank. They look at 1,000 global large cap companies and evaluate them for return on equity, return on invested capital, and accounting accruals … quantifiable proxies for the most common ways that investors think about quality. Because the goal is to isolate the Quality factor, the index is long in equal amounts the top 20% of measured  companies and short the bottom 20% (so market neutral), and has equal amounts invested long and short in the component sectors of the market (so sector neutral). The chart begins on March 9, 2009, when the Fed launched its first QE program.

Over the past eight and a half years, Quality has been absolutely useless as an investment derivative. You’ve made a grand total of not quite 3% on your investment, while the S&P 500 is up almost 300%.

Long term there are two strategies which have been shown to consistently improve risk adjusted return from the stock market, momentum (by which I mean trend following) and value (I refer you to Graham and Dodd). Last month the Managed Futures community, consisting primarily of momentum based strategies, had its worst month for 17 years. Value, as the chart above declares, has been out of favour since the great recession at the very least. Indiscriminate Momentum has been the star performer over the same period. The chart below uses a log scale and is adjusted for inflation:-

At the current level we are certainly sucking on ether in terms of the variance from trend. If the driver has been QE and QQE then the experiment have been unprecedented; a policy mistake is almost inevitable, as Central Banks endeavour to unwind their egregious largesse.

My good friend, and a former head of bond trading at Bankers Trust, wrote a recent essay on the subject of Federal Reserve policy in the new monetary era. He has kindly consented to allow me to quote some of his poignant observations, he starts by zooming out – the emphasis is mine:-

Recent debates regarding future monetary policy seem to focus on a degree of micro-economic precision no longer reliably available from the monthly data.  Arguments about minor changes in the yield curve or how many tightening moves will occur this year risk ignoring the dramatic adjustments in all major economic policies of the United States, not to mention the plausible array of international responses…

for the first time since the demise of Bear Stearns, et al; global sovereign bond markets will have to seek out a new assemblage of price-sensitive buyers…

Given that QE was a systematic purchase programme devoid of any judgement about relative or absolute value, the return of the price-sensitive buyer, is an important distinction. The author goes on to question how one can hope to model the current policy mix.

 …There is no confident means of modeling the interaction of residual QE, tax reform, fiscal pump-priming, and now aggressive tariffs. This Mnuchin concoction is designed to generate growth exceeding 3%.  If successful, the Fed’s inflation goal will finally be breached in a meaningful way…

…Classical economists will argue that higher global tariffs are contractionary; threatening the recession that boosts adrenaline levels among the passionate yield curve flattening crowd.  But they are also inflationary as they reduce global productivity and bolster input prices…

Contractionary and inflationary, in other words stagflationary. I wonder whether the current bevvy of dovish central bankers will ever switch their focus to price stability at the risk of destroying growth – and the inevitable collapsed in employment that would signify?

Hot on the heels of Wednesday’s rate hike, the author (who wrote the essay last week) goes on to discuss the market fixation with 25bp rate increases – an adage from my early days in the market was, ‘Rates go up by the lift and down by the stairs,’ there is no reason why the Fed shouldn’t be more pre-emptive, except for the damage it might do to their reputation if catastrophe (read recession) ensues. A glance at the 30yr T-Bond chart shows 3.25% as a level of critical support. Pointing to the dwindling of foreign currency reserves of other central banks as the effect of tariffs reduces their trade surplus with the US, not to mention the deficit funding needs of the current administration, Allan concludes:-

…Powell will hopefully resort to his own roots as a pragmatic investment banker rather than try to retool Yellenism.  He will have to be very creative to avoid abrupt shifts in liquidity preference.  I strongly advise a very open mind on Powell monetary policy.  From current levels, a substantial steepening of the yield curve is far more likely than material flattening, as all fiscal indicators point toward market-led higher bond yields.

What we witnessed in the stock market during February was a wake-up call. QE is being reversed in the US and what went up – stocks, bonds and real estate – is bound to come back down. Over the next decade it is unlikely that stocks can deliver the capital appreciation we have witnessed during the previous 10 years.

Whilst global stock market correlations have declined of late they remain high (see the chart below) the value based approach – which, as the Deutsche Bank index shows, has underwhelmed consistently for the past decade – may now offer a defensive alternative to exiting the stock market completely. This does not have to be Long/Short or Equity Market Neutral. One can still find good stocks even when overall market sentiment is dire.

For momentum investors the first problem with stocks is their relatively high correlation. A momentum based strategy may help if there is a dramatic sell-off, but if the markets move sideways, these strategies are liable to haemorrhage via a steady sequence of false signals, selling at the nadir of the trading range and buying at the zenith, as the overall market moves listlessly sideways. Value strategies generally fare better in this environment by purchasing the undervalued and selling the overvalued.

Conclusion

I was asked this week, why I am still not bearish on the stock market? The simple answer is because the market has yet to turn. ‘The market can remain irrational longer than I can remain solvent,’ is one of Keynes more enduring observations. Fundamental valuations suggest that stocks will underperform over the next decade because they are expensive today. This implies that a bear market may be nigh, but it does not guarantee it. Using a very long-term moving average one might not have exited the stock market since the 1980’s, every bear-market since then has been a mere corrective wave.

The amount of political capital tied up in the stock market is unparalleled. In a world or QE, fiat currencies, budget deficits and big government, it seems foolhardy to bite the hand which feeds. Stocks may well suffer from a sharp and substantial correction. Even if they don’t plummet like a stone they are likely to deliver underwhelming returns over the next decade, but I still believe they offer the best value in the long run. A tactical reduction in exposure may be warranted but be prepared to wait for a protracted period gaining little or nothing from your cash. Diversify into other asset classes but remember the degree to which the level of interest rates and liquidity may influence their prices. Unfashionable value investing remains a tempting alternative.
