A slow-burning problem (if at all)

In the words of the great Yogi Berra, the shenanigans in global banking over the past two weeks are “like déjà vu all over again.” The failures of Silicon Valley Bank and Signature Bank in the US and the forced merger of Credit Suisse with UBS have given rise to fears of another bank-induced shock to the global system along the lines of 2008. My own view, for what it is worth, is that we are not on the cusp of a similar shock. But this does not mean that we will escape unscathed and there are lots of questions surrounding the current state of the banking landscape which will continue to reverberate and which may yet have far-reaching implications.

Balance sheet issues

The good news is that systemically important banks are adequately capitalised, at least according to the requirements laid down in the Basel III legislation implemented in the wake of the GFC (see table below). But as with all past crises, the introduction of new regulations is a response to the last war.

The academic evidence makes it clear that bank runs occur when depositors’ demand for liquidity is greater than banks’ ability to supply it. In an important 1983 paper by Douglas Diamond and Philip Dybvig[1] (for which they collected a Nobel Prize in economics last year, along with Ben Bernanke for significantly improving “our understanding of the role of banks in the economy”) the authors highlight that maturity mismatch, when banks’ assets are long-term but their liabilities are short-term in nature, results in an inherent instability in the event that depositors want their money back. This was precisely the problem faced by SVB where 43% of its assets were in the form of held-to-maturity securities marked at book value (significantly above their market value). It suggests that regulators may have to look more closely at the maturity structure of bank balance sheets in future.

Rising rates are the biggest problem

The reasons why banks are once again front and centre of the market debate are complex. But in large part the issues can be traced back to the sharp global monetary tightening that we have seen over the past year. Central banks have raised rates in response to inflation without really having a good understanding of how the monetary transmission process works. Indeed, so far any declines in inflation are due only to the impact of big oil price spikes dropping out of the calculations – nothing to do with tighter monetary policy – and there are real concerns that a sharp tightening of monetary policy will throw the European and US economies into recession. The pace of tightening in the US is the fastest since the late-1970s with the Fed funds rate having risen by 475bps in 13 months (an average of 0.36bps per month). The last time policy was tightened so aggressively was in 1978-79 and the result was recession.

Although in theory rising interest rates are good news for a banking sector that borrows short and lends long, higher rates also have adverse consequences. Aside from the fact that US banks are sitting on a bond portfolio whose market value is worth considerably less than they paid for it, there are mounting concerns about banks’ portfolio of commercial property. The dual impact of an economic slowdown and higher rates take the edge off property prices, reducing the value of the collateral against which loans are secured. Banks will be less willing to lend in these circumstances, potentially triggering further weakness in the commercial market. The fact that this sits on the balance sheet of regional US banks, which account for 70% of all commercial property lending, further amplifies the risks posed by the asset position of the US banking sector.

An additional problem is that banks have suffered from deposit outflows over the past year (chart above). The reason is that deposit rates tend to rise more slowly than lending rates with the result that depositors have an incentive to seek higher yielding alternatives, which goes a long way towards explaining why there has been a big inflow into US money market funds in recent weeks. According to Refinitiv Lipper data, US money market funds received a net $59.3bn of inflows in the week to March 29 bringing the monthly total to $273.3bn versus bank deposit outflows of $187bn over the first half of March.

Implications

The conditions which triggered the Lehman’s crisis of 2008 are not present today. Central banks have adhered to the Bagehot doctrine of providing ample liquidity against good collateral (whether they have done so at a penalty rate is moot). Although markets were spooked by the Credit Suisse issue and market concerns about Deutsche Bank were prevalent a week ago, if there are problems in the global banking system, they are more likely to emerge in the US than Europe.

By fully guaranteeing SVB depositors, despite the fact that many of them had deposits in excess of the $250k limit, the US authorities have sent a signal that there is no need for a rush to the exit which ought to limit the prospect of further bank runs. But whilst the kind of explosive shock which resulted from the Lehman’s bust is unlikely, there is still the prospect of a more slow-burn problem.

In some ways, the recent problems are reminiscent of the Savings and Loan crisis of the late-1980s/early-1990s. S&Ls were subject to limits on the interest rates they could offer to depositors, which consequently led to a major outflow of deposits to money market funds. Deregulation in the early 1980s encouraged them make risky loans in a bid to generate attractive returns, which went sour as the Fed tightened policy. S&Ls were encouraged to act in this way by taxpayer-funded guarantees provided by the Federal Savings and Loan Insurance Corporation which created an enormous moral hazard problem. Between 1986 and 1995 almost one-third of S&L institutions ceased to exist and although it was a slow burner, the demise of S&Ls was a contributory factor to the US recession of 1990-91.

This is not to say that history will necessarily repeat itself but it should act as a warning signal for central bankers who continue to believe that excess inflation is the main problem for them to worry about. Rapid monetary tightening will exacerbate weaknesses in the financial system and a prudent central banker might wish to hold fire on further rate hikes, especially given the magnitude of the tightening put in place over the last year.

Vladgrind

My initial thought twelve months ago following the Russian invasion of Ukraine was that the tectonic plates have shifted. Nothing that has happened in the interim has caused me to change my view. It soon became obvious that the war was going to be a more protracted affair than Vladimir Putin anticipated (or was told by his advisers) and slightly belatedly the west realised that it had a duty to provide physical support to show that its support for democracy amounted to more than just words. There has been a cost, both economically and geopolitically, and the issue over the next twelve months will be whether the international community is prepared to continue paying the price.

Polling evidence shows that Europeans and American citizens believe Ukraine should continue its fight to regain the territory occupied by Russia, although in other geopolitically important states there is less support for such a position (chart above). The continental European position is understandable. There is more concern than elsewhere that the war could spill over and draw them in to defend their territory or that of their neighbours. Quite how events will pan out over the next twelve months is difficult to say. The likelihood is that the war of attrition will continue, with Ukraine not having the resources to push Russian forces out of their territory but Russia unable to make significant territorial gains. Further ahead, the manpower differential makes it difficult to see how Ukraine can regain the territory it has lost without regime change in Moscow, suggesting that some form of negotiated settlement might be the best we can hope for.

The economy has so far avoided the worst case outcomes …

Undoubtedly the Ukrainian war has had a big impact on the global economy, following hard on the heels of the Covid pandemic. This has manifested in an inflation shock, the likes of which we have not seen in 40 years, and prompted central banks around the world to raise interest rates, having kept them at historical lows for far too long after the GFC. The slowdown in the global economy has been pronounced but perhaps less dramatic than anticipated towards the end of 2022, with euro area GDP eking out a small rise of 0.1% q/q in 2022Q4, thus ensuring that the economy continues to avoid recession. Germany is facing a tougher haul but even the 0.4% contraction recorded in Q4 was better than anticipated a few months ago.

Germany in particular has coped far better than anticipated in managing its gas storage. As of end-February, storage levels were at 71.7% of capacity (chart below) whilst gas consumption in the week beginning 13 February 2023 was 22.7% below the average for 2018 to 2021. As a consequence, Europe’s largest economy has avoided significant blackouts which has prevented sharper falls in output. But contrary to suggestions expressed in the media of late, we are far from out of the woods. Indeed, although it is likely that Germany – and indeed the rest of Europe – has sufficient gas on hand to get through to the autumn, much depends on how easily gas storage levels can be topped up ahead of the winter. In the event that Germany cannot easily top up supplies from non-Russian sources in 2023, we could go into next winter with perilously low supply levels which would be problematic if there is a cold winter.

… But …

A tightening of monetary policy has helped to curb demand but this all points to the fact that rather than a winter 2023 recession, we could instead face a similar outcome in twelve months’ time. For this reason, markets are looking nervously at the actions of central banks as they continue to tighten monetary policy in the face of a rising inflation threat. But it is not headline inflation they care about so much as the pickup in core inflation as prices respond to the big rise in energy costs that occurred in 2022. On top of this central banks also care about the prospect of a response from wage inflation which could set off a wage-price spiral. So they keep nudging rates higher. And the higher they go, the more likely the prospect that the economy finally tips into recession – not as a direct result of higher energy costs but as a result of tighter monetary policy.

That might seem a remote prospect in the US today but the operation of monetary policy involves lags which are often not known with any precision. As interest rates in the US rise and inflation falls, so the real interest rate – which is assumed to be a key factor in driving real activity rates – becomes less negative. Based on latest data, for example, the real Fed funds rate climbed from a low of -8.2% in March 2022 to -1.8% by January 2023. Admittedly this is still in negative territory but add 25bps to the funds rate and assume inflation comes down by another 1.5 percentage points to 4.8% and the real rate is back at zero. The further inflation falls as the energy price shock drops out of the calculations, the greater the upward pressure on real rates and the bigger the drag on the US economy – and by definition the rest of the world.

Back to where we started

Putin calculated that NATO’s European members, which were heavily dependent on Russian gas, would scale back their opposition to the invasion as the restriction of gas supplies put intolerable pressure on the European economy. So far this calculation has not worked out. European opposition may yet soften if the economy falls into recession, either as a result of domestic policy errors or those of the Federal Reserve. However, rather than a short, sharp recession, it is far more likely that the European economy will experience a longer period of little to no growth, which will raise the pressure on policymakers in different ways. Coupled with high budget deficits, which may prompt some form of fiscal consolidation, the near-term outlook for the European economy is not a pretty one. The polling data suggests that European governments can afford to stay the course in 2023. Whether they will be prepared to do so further ahead as elections loom may be another matter.
