Canary in the coal-mine – Emerging market contagion

  • Emerging market currencies, bonds and stocks have weakened
  • Fears about the impact of US tariffs have been felt here most clearly
  • The risk to Europe and Japan is significant
  • Turkey may be the key market to watch

As US interest rates continue to normalise and US tariffs begin to bite, a number of emerging markets (EM’s) have come under pressure. Of course, the largest market to exhibit signs of stress is China, the MSCI China Index is down 7% since mid-June, whilst the RMB has also weakened against the US$ by more than 6% since its April low. Will contagion spread to developed markets and, if so, which country might be the ‘carrier’?

To begin to answer these questions we need to investigate this year’s casualties. Argentina is an obvious candidate. Other troubled countries include Brazil, Egypt and Turkey. In each case, government debt has exacerbated instability, as each country’s currency came under pressure. Other measures of instability include budget and trade deficits.

In an effort to narrow the breadth of this Macro Letter, I will confine my analysis to those countries with twin government and current account deficits. In the table which follow, the countries are sorted by percentage of world GDP. The colour coding reflects the latest MSCI categorisation; yellow, denotes a fully-fledged EM, white, equals a standard EM, green, is on the secondary list and blue is reserved for those countries which are so ‘frontier’ in nature as not to be currently assessed by MSCI: –

EM Debt and GDP

For the purposes of this analysis, the larger the EM as a percentage of world GDP and the higher its investment rating, the more likely it is to act as a catalyst for contagion. Whilst this is a simplistic approach, it represents a useful the starting point.

Back in 2005, in a futile attempt to control the profligacy of European governments, the European Commission introduced the Stability and Growth Pact. It established at maximum debt to GDP ratio of 60% and budget deficit ceiling of 3%, to be applied to all members of the Eurozone. If applied to the EM’s listed above, the budget deficit constraint could probably be relaxed: these are, generally, faster growing economies. The ratio of debt to GDP should, however, be capped at a lower percentage. The government debt overhang weighs more heavily on smaller economies, especially ones where the percentage of international investors tends to be higher. Capital flight is a greater risk for EM’s than for developed economies, which are insulated by a larger pool of domestic investors.

Looking at the table again, from a financial stability perspective, the percentage of non-domestic debt to GDP, is critical. A sudden growth stop, followed by capital flight, usually precipitates a collapse in the currency. External debt can prove toxic, even if it represents only a small percentage of GDP, since the default risk associated with a collapsing currency leads to a rapid rise in yields, prompting further capital flight – this is a viscous circle, not easily broken. The Latin American debt crisis of the 1980’s was one of the more poignant examples of this pattern. Unsurprisingly, in the table above, the percentage of external debt to GDP grows as the economies become smaller, although there is a slight bias for South American countries to continue to borrow abroad. Perhaps a function of their proximity to the US capital markets. Interestingly, by comparison with developed nations, the debt to GDP ratios in most of these EM countries is relatively modest: a sad indictment of the effectiveness of QE as a policy to strengthen the world financial system – but I digress.

Our next concern ought to be the trade balance. Given the impact that US tariffs are likely to have on export nations, both emerging and developed, it is overly simplistic to look, merely, at EM country exports to the US. EM exports to Europe, Japan and China are also likely to be vulnerable, as US tariffs are enforced. Chile and Mexico currently run trade surpluses, but, since their largest trading partner is the US, they still remain exposed.

This brings us to the second table which looks at inflation, interest rates, 10yr bond yields, currencies and stock market performance: –

EM Markets and Inflation

In addition to its absolute level, the trend of inflation is also an important factor to consider. India has seen a moderate increase since 2017, but price increases appear steady not scary. Brazil has seen a recent rebound after the significant moderation which followed the 2016 spike. Mexican inflation has moderated since late 2017, posing little cause for concern. Indonesian price rises are at the lower end of their post Asian crisis range. Turkey, however, is an entirely different matter. It inflation is at its highest since 2004 and has broken to multiyear highs in the last two months. Inflation trends exert a strong influence on interest rate expectations and Turkish 10yr yields have risen by more than 5% this year, whilst it currency has fallen further than any in this group, barring the Argentinian Peso. For comparison, the Brazilian Real is the third weakest, followed, at some distance, by the Indian Rupee.

India, Brazil, Mexico and Indonesia may be among the largest economies in this ‘contagion risk’ group, but Turkey, given its geographic proximity to the EU may be the linchpin.

Is Turkey the canary?

The recent Turkish elections gave President Erdogan an increased majority. His strengthened mandate does not entirely remove geopolitical risk, but it simplifies our analysis of the country from an economic perspective. Short-term interest rates are 17.75%, the second highest in the group, behind Argentina. The yield curve is inverted: and both the currency and stock market have fared poorly YTD. Over the last 20 years, Turkish GDP has averaged slightly less than 5%, but this figure is skewed by three sharp recessions (‘98, ‘01 and ‘08). The recent trend has been volatile but solid. 10yr bond yields, by contrast, have been influenced by a more than doubling of short-term interest rates, in defence of the Turkish Lira. This aggressive action, by their central bank, makes the economy vulnerable to an implosion of growth, as credit conditions deteriorate rapidly.

Conclusion and investment opportunities

In Macro Letter – No 96 – 04-05-2018 – Is the US exporting a recession? I concluded in respect of Europe that: –

…the [stock] 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.

Over the past few months EM currencies have declined, their bond yields have increased and their stock markets have generally fallen. In respect of tariffs, President Trump has done what he promised. Markets, like Mexico and Chile, reacted early and seem to have stabilised. Argentina had its own internal issues with which to contend. The Indian economy continues its rapid expansion, despite higher oil prices and US tariffs. It is Turkey that appears to be the weakest link, but this may be as much a function of the actions of its central bank.

If, over the next few months, the Turkish Lira stabilises and official rates moderate, the wider economy may avoid recession. Whilst much commentary concerning EM risks will focus on the fortunes of China, it is still a relatively closed, command economy: and, therefore, difficult to predict. It will be at least as useful to focus on the fortunes of Turkey. It may give advanced warning, like the canary in the coal-mine, which makes it my leading indicator of choice.

 

 

Robots, employment and the mis-measurement of productivity

Robots, employment and the mis-measurement of productivity

Macro Letter – No 97 – 18-05-2018

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.

What to expect from Central Bankers

Macro Letter – No 94 – 06-04-2018

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.

*MOVE = Merrill lynch Option Volatility Estimate

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

Source: Borio et al, 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.
