Central bank balance sheet reductions – will anyone follow the Fed?

  • The next wave of QE will be different, credit spreads will be controlled
  • The Federal Reserve may continue to tighten but few other CB’s can follow
  • ECB balance sheet reduction might occur if a crisis does not arrive first
  • Interest rates are likely to remain structurally lower than before 2008

The Federal Reserve’s response to the great financial recession of 2008/2009 was swift by comparison with that of the ECB; the BoJ was reticent, too, due to its already extended balance sheet. Now that the other developed economy central banks have fallen into line, the question which dominates markets is, will other central banks have room to reverse QE?

Last month saw the publication of a working paper from the BIS – Risk endogeneity at the lender/investor-of-last-resort – in which the authors investigate the effect of ECB liquidity provision, during the Euro crisis of 2010/2012. They also speculate about the challenge balance sheet reduction poses to systemic risk. Here is an extract from the non-technical summary (the emphasis is mine): –

The Eurosystem’s actions as a large-scale lender- and investor-of-last-resort during the euro area sovereign debt crisis had a first-order impact on the size, composition, and, ultimately, the credit riskiness of its balance sheet. At the time, its policies raised concerns about the central bank taking excessive risks. Particular concern emerged about the materialization of credit risk and its effect on the central bank’s reputation, credibility, independence, and ultimately its ability to steer inflation towards its target of close to but below 2% over the medium term.

Against this background, we ask: Can central bank liquidity provision or asset purchases during a liquidity crisis reduce risk in net terms? This could happen if risk taking in one part of the balance sheet (e.g., more asset purchases) de-risks other balance sheet positions (e.g., the collateralized lending portfolio) by a commensurate or even larger amount. How economically important can such risk spillovers be across policy operations? Were the Eurosystem’s financial buffers at all times sufficiently high to match its portfolio tail risks? Finally, did past operations differ in terms of impact per unit of risk?…

We focus on three main findings. First, we find that (Lender of last resort) LOLR- and (Investor of last resort) IOLR-implied credit risks are usually negatively related in our sample. Taking risk in one part of the central bank’s balance sheet (e.g., the announcement of asset purchases within the Securities Market Programme – SMP) tended to de-risk other positions (e.g., collateralized lending from previous longer-term refinancing operations LTROs). Vice versa, the allotment of two large-scale (very long-term refinancing operations) VLTRO credit operations each decreased the one-year-ahead expected shortfall of the SMP asset portfolio. This negative relationship implies that central bank risks can be nonlinear in exposures. In bad times, increasing size increases risk less than proportionally. Conversely, reducing balance sheet size may not reduce total risk by as much as one would expect by linear scaling. Arguably, the documented risk spillovers call for a measured approach towards reducing balance sheet size after a financial crisis.

Second, some unconventional policy operations did not add risk to the Eurosystem’s balance sheet in net terms. For example, we find that the initial OMT announcement de-risked the Eurosystem’s balance sheet by e41.4 bn in 99% expected shortfall (ES). As another example, we estimate that the allotment of the first VLTRO increased the overall 99% ES, but only marginally so, by e0.8 bn. Total expected loss decreased, by e1.4 bn. We conclude that, in extreme situations, a central bank can de-risk its balance sheet by doing more, in line with Bagehot’s well-known assertion that occasionally “only the brave plan is the safe plan.” Such risk reductions are not guaranteed, however, and counterexamples exist when risk reductions did not occur.

Third, our risk estimates allow us to study past unconventional monetary policies in terms of their ex-post ‘risk efficiency’. Risk efficiency is the notion that a certain amount of expected policy impact should be achieved with a minimum level of additional balance sheet risk. We find that the ECB’s Outright Monetary Transactions – OMT program was particularly risk efficient ex-post since its announcement shifted long-term inflation expectations from deflationary tendencies toward the ECB’s target of close to but below two percent, decreased sovereign benchmark bond yields for stressed euro area countries, while lowering the risk inherent in the central bank’s balance sheet. The first allotment of VLTRO funds appears to have been somewhat more risk-efficient than the second allotment. The SMP, despite its benefits documented elsewhere, does not appear to have been a particularly risk-efficient policy measure.

This BIS research is an important assessment of the effectiveness of ECB QE. Among other things, the authors find that the ‘shock and awe’ effectiveness of the first ‘quantitative treatment’ soon diminished. Liquidity is the methadone of the market, for QE to work in future, a larger and more targeted dose of monetary alchemy will be required.

The paper provides several interesting findings, for example, the Federal Reserve ‘taper-tantrum’ of 2013 and the Swiss National Bank decision to unpeg the Swiss Franc in 2015, did not appear to influence markets inside the Eurozone, once ECB president, Mario Draghi, had made its intensions plain. Nonetheless, the BIS conclude that (emphasis, once again, is mine): –

…collateralized credit operations imply substantially less credit risks (by at least one order of magnitude in our crisis sample) than outright sovereign bond holdings per e1 bn of liquidity owing to a double recourse in the collateralized lending case. Implementing monetary policy via credit operations rather than asset holdings, whenever possible, therefore appears preferable from a risk efficiency perspective. Second, expanding the set of eligible assets during a liquidity crisis could help mitigate the procyclicality inherent in some central bank’s risk protection frameworks.

In other words, rather than exacerbate the widening of credit spreads by purchasing sovereign debt, it is preferable for central banks to lean against the ‘flight to quality’ tendency of market participants during times of stress.

The authors go on to look at recent literature on the stress-testing of central bank balance sheets, mainly focussing on analysis of the US Federal Reserve. Then they review ‘market-risk’ methods as a solution to the ‘credit-risk’ problem, employing non-Gaussian methods – a prescient approach after the unforeseen events of 2008.

Bagehot thou shouldst be living at this hour (with apologies to Wordsworth)

The BIS authors refer on several occasions to Bagehot. I wonder what he would make of the current state of central banking? Please indulge me in this aside.

Walter Bagehot (1826 to 1877) was appointed by Richard Cobden as the first editor of the Economist. He is also the author of perhaps the best known book on the function of the 19th century money markets, Lombard Street (published in 1873). He is famed for inventing the dictum that a central bank should ‘lend freely, at a penalty rate, against good collateral.’ In fact he never actually uttered these words, they have been implied. Even the concept of a ‘lender of last resort’, to which he refers, was not coined by him, it was first described by Henry Thornton in his 1802 treatise – An Enquiry into the Nature and Effects of the Paper Credit of Great Britain.

To understand what Bagehot was really saying in Lombard Street, this essay by Peter Conti-Brown – Misreading Walter Bagehot: What Lombard Street Really Means for Central Banking – provides an elegant insight: –

Lombard Street was not his effort to argue what the Bank of England should do during liquidity crises, as almost all people assume; it was an argument about what the Bank of England should openly acknowledge that it had already done.

Bagehot was a classical liberal, an advocate of the gold standard; I doubt he would approve of the nature of central banks today. He would, I believe, have thrown his lot in with the likes of George Selgin and other proponents of Free Banking.

Conclusion and Investment Opportunities

Given the weakness of European economies it seems unlikely that the ECB will be able to follow the lead of the Federal Reserve and raise interest rates in any meaningful way. The unwinding of, at least a portion of, QE might be easier, since many of these refinancing operations will naturally mature. For arguments both for and against CB balance sheet reduction this paper by Charles Goodhart – A Central Bank’s optimal balance sheet size? is well worth reviewing. A picture, however, is worth a thousand words, although I think the expected balance sheet reduction may be overly optimistic: –

Come the next crisis, I expect the ECB to broaden the range of eligible securities and instruments that it is prepared to purchase. The ‘Draghi Put’ will gain greater credence as it encompasses a wider array of credits. The ‘Flight to Quality’ effect, driven by swathes of investors forsaking equities and corporate bonds, in favour of ‘risk-free’ government securities, will be shorter-lived and less extreme. The ‘Convergence Trade’ between the yields of European government bonds will regain pre-eminence; I can conceive the 10yr BTP/Bund spread testing zero.

None of this race to zero will happen in a straight line, but it is important not to lose sight of the combined power of qualitative and quantitative easing. The eventual ‘socialisation’ of common stock is already taking place in Japan. Make no mistake, it is already being contemplated by a central bank near you, right now.

Sustainable government debt – an old idea refreshed

  • New research from the Peterson Institute suggests bond yields may fall once more
  • Demographic forces and unfunded state liabilities point to an inevitable reckoning
  • The next financial crisis may be assuaged with a mix of fiscal expansion plus QQE
  • Pension fund return expectations for bonds and stocks need to be revised lower

The Peterson Institute has long been one of my favourite sources of original research in the field of economics. They generally support free-market ideas, although they are less than classically liberal in their approach. I was, nonetheless, surprised by the Presidential Lecture given at the annual gathering of the American Economic Association (AEA) by Olivier Blanchard, ex-IMF Chief Economist, now at the Peterson Institute – Public Debt and Low Interest Rates. The title is quite anodyne, the content may come to be regarded as incendiary. Here is part of his introduction: –

Since 1980, interest rates on U.S. government bonds have steadily decreased. They are now lower than the nominal growth rate, and according to current forecasts, this is expected to remain the case for the foreseeable future. 10-year U.S. nominal rates hover around 3%, while forecasts of nominal growth are around 4% (2% real growth, 2% inflation). The inequality holds even more strongly in the other major advanced economies: The 10-year UK nominal rate is 1.3%, compared to forecasts of 10-year nominal growth around 3.6% (1.6% real, 2% inflation). The 10-year Euro nominal rate is 1.2%, compared to forecasts of 10-year nominal growth around 3.2% (1.5% real, 2% inflation). The 10-year Japanese nominal rate is 0.1%, compared to forecasts of 10-year nominal growth around 1.4% (1.0% real, 0.4% inflation).

The question this paper asks is what the implications of such low rates should be for government debt policy. It is an important question for at least two reasons. From a policy viewpoint, whether or not countries should reduce their debt, and by how much, is a central policy issue. From a theory viewpoint, one of pillars of macroeconomics is the assumption that people, firms, and governments are subject to intertemporal budget constraints. If the interest rate paid by the government is less the growth rate, then the intertemporal budget constraint facing the government no longer binds. What the government can and should do in this case is definitely worth exploring.

The paper reaches strong, and, I expect, surprising, conclusions. Put (too) simply, the signal sent by low rates is that not only debt may not have a substantial fiscal cost, but also that it may have limited welfare costs.

Blanchard’s conclusions may appear radical, yet, in my title, I refer to this as an old idea, allow me to explain. In business it makes sense, all else equal, to borrow if the rate of interest paid on your loan is lower than the return from your project. At the national level, if the government can borrow at below the rate of GDP growth it should be sustainable, since, over time (assuming, of course, that it is not added to) the ratio of debt to GDP will naturally diminish.

There are plenty of reasons why such borrowing may have limitations, but what really interests me, in this thought provoking lecture, is the reason governments can borrow at such low rates in the first instance. One argument is that as GDP grows, so does the size of the tax base, in other words, future taxation should be capable of covering the on-going interest on today’s government borrowing: the market should do the rest. Put another way, if a government become overly profligate, yields will rise. If borrowing costs exceed the expected rate of GDP there may be a panicked liquidation by investors. A government’s ability to borrow will be severely curtailed in this scenario, hence the healthy obsession, of many finance ministers, with debt to GDP ratios.

There are three factors which distort the cosy relationship between the lower yield of ‘risk-free’ government bonds and the higher percentage levels of GDP growth seen in most developed countries; investment regulations, unfunded liabilities and fractional reserve bank lending.

Let us begin with investment regulations, specifically in relation to the constraints imposed on pension funds and insurance companies. These institutions are hampered by prudential measures intended to guarantee that they are capable of meeting payment obligations to their customers in a timely manner. Mandated investment in liquid assets are a key construct: government bonds form a large percentage of their investments. As if this was not sufficient incentive, institutions are also encouraged to purchase government bonds as a result of the zero capital requirements for holding these assets under Basel rules.

A second factor is the uncounted, unfunded, liabilities of state pension funds and public healthcare spending. I defer to John Mauldin on this subject. The 8th of his Train-Wreck series is entitled Unfunded Promises – the author begins his calculation of total US debt with the face amount of all outstanding Treasury paper, at $21.2trln it amounts to approximately 105% of GDP. This is where the calculations become disturbing: –

If you add in state and local debt, that adds another $3.1 trillion to bring total government debt in the US to $24.3 trillion or more than 120% of GDP.

Mauldin goes on to suggest that this still underestimates the true cost. He turns to the Congressional Budget Office 2018 Long-Term Budget Outlook – which assumes that federal spending will grow significantly faster than federal revenue. On the basis of their assumptions, all federal tax revenues will be consumed in meeting social security, health care and interest expenditures by 2041.

Extrapolate this logic to other developed economies, especially those with more generous welfare commitments than the US, and the outlook for rapidly aging, welfare addicted developed countries is bleak. In a 2017 white paper by Mercer for World Economic Forum – We Will Live to 100 – the author estimates that the unfunded liabilities of US, UK, Netherlands, Japan, Australia, Canada, China and India will rise from $70trln in 2015 to $400trln in 2050. These countries represent roughly 60% of global GDP. I extrapolate global unfunded liabilities of around $120trln today rising to nearer $650trln within 20 years: –

For an in depth analysis of the global pension crisis this 2016 research paper from Citi GPS – The Coming Pensions Crisis – is a mine of information.

In case you are still wondering how, on earth, we got here? This chart from Money Week shows how a combination of increased fiscal spending (to offset the effect of the bursting of the tech bubble in 2000) combined with the dramatic fall in interest rates (since the great financial recession of 2008/2009) has damaged the US state pension system: –

The yield on US Treasury bonds has remained structurally higher than most of the bonds of Europe and any of Japan, for at least a decade.

The third factor is the fractional reserve banking system. Banks serve a useful purpose intermediating between borrowers and lenders. They are the levers of the credit cycle, but their very existence is testament to their usefulness to their governments, by whom they are esteemed for their ability to purchase government debt. I discuss – A history of Fractional Reserve Banking – or why interest rates are the most important influence on stock market valuations? in a two part essay I wrote for the Cobden Centre in October 2016. In it I suggest that the UK banking system, led by the Bank of England, has enabled the UK government to borrow at around 3% below the ‘natural rate’ of interest for more than 300 years. The recent introduction of quantitative easing has only exaggerated the artificial suppression of government borrowing costs.

Before you conclude that I am on a mission to change the world financial system, I wish to point out that if this suppression of borrowing costs has been the case for more than 300 years, there is no reason why it should not continue.

Which brings us back to Blanchard’s lecture at the AEA. Given the magnitude of unfunded liabilities, the low yield on government bonds is, perhaps, even more remarkable. More alarmingly, it reinforces Blanchard’s observation about the greater scope for government borrowing: although the author is at pains to advocate fiscal rectitude. If economic growth in developed economies stalls, as it has for much of the past two decades in Japan, then a Japanese redux will occur in other developed countries. The ‘risk-free’ rate across all developed countries will gravitate towards the zero bound with a commensurate flattening in yield curves. Over the medium term (the next decade or two) an increasing burden of government debt can probably be managed. Some of the new borrowing may even be diverted to investments which support higher economic growth. The end-game, however, will be a monumental reckoning, involving wholesale debt forgiveness. The challenge, as always, will be to anticipate the inflection point.

Conclusion and Investment Opportunities

Since the early-1990’s analysts have been predicting the end of the bond bull market. Until quite recently it was assumed that negative government bond yields were a temporary aberration reflecting stressed market conditions. When German schuldscheine (the promissory notes of the German banking system) traded briefly below the yield of German Bunds, during the reunification in 1989, the ‘liquidity anomaly’ was soon rectified. There has been a sea-change, for a decade since 2008, US 30yr interest rate swaps traded at a yield discount to US Treasuries – for more on this subject please see – Macro Letter – No 74 – 07-04-2017 – US 30yr Swaps have yielded less than Treasuries since 2008 – does it matter?

With the collapse in interest rates and bond yields, the unfunded liabilities of governments in developed economies has ballooned. A solution to the ‘pension crisis,’ higher bond yields, would sow the seeds of a wider economic crisis. Whilst governments still control their fiat currencies and their central banks dictate the rate of interest, there is still time – though, I doubt, the political will – to make the gradual adjustments necessary to right the ship.

I have been waiting for US 10yr yields to reach 4.5%, I may be disappointed. For investors in fixed income securities, the bond bull market has yet to run its course. Negative inflation adjusted returns will become the norm for risk-free assets. Stock markets may be range-bound for a protracted period as return expectations adjust to a structurally weaker economic growth environment.
