The Nobel Prize for economics was recently awarded to former Fed Chair Ben Bernanke and two other American economists, Douglas Diamond and Philip Dybvig. The award was for their analysis that helped overcome the Global Financial Crisis of 2008-09. Which is fair enough. However, the award honouring central bank judgement ironically comes at a time when central bankers are struggling to cope with a more recent crisis, caused by the Covid-19 lockdowns, its inflationary aftermath and the still more recent shock to energy prices caused by the war in Ukraine.

There are many precedents for the best way to deal with a banking crisis, which boil down to printing more money. There are no obvious precedents for the best way to deal with the lockdowns that were accompanied by an even larger increase in the money supply. Having said that, a glance at monetary history, especially at what happens to economies when wars break out, would have told us that the post-Covid acceleration in spending and prices should not have come as a surprise. The Fed could have done with a little more acquaintance with monetary history.

The participants in financial markets responsible for managing the accumulated savings of their communities have had difficulty in anticipating the recent central bank actions and their consequences. The agreed task of central banks is to make it easier for the market to do so. Yet the prospect of a recession, as policy-determined interest rates have been pushed dramatically higher – with more increases to follow – has loomed ever larger.  This confusion does no credit to central bankers.

The destruction of hard-earned wealth has occurred on a devastating scale. The benchmark S&P 500 has lost 20% of its value (or US$8.7 trillion) since the start of the year. The larger portfolios of government bonds have suffered even greater losses in US dollars. The global government bond index is also about 20% weaker, year-to-date.

The most surprising feature of recent market moves has been the failure of the bond markets to provide the protection for portfolios that they usually do. The safe haven has been to hold US dollars on very short maturities. Moreover, US long bond yields have increased not because more inflation is expected. It has been the real yields on inflation protected government securities (TIPS) that have moved higher, reducing the gap between real and nominal yields that represent compensation for assuming inflation risks in bond portfolios.

The market now expects inflation to average 2.5% a year over the next 10 years, in other words less inflation in the US than it expected earlier in the year, and little more than the 2% a year average rates of inflation over the next 10 years, which is the Fed target. So why the panic at the Fed? And why has the real cost of capital risen when the outlook for growth has deteriorated and the value of capital has fallen? Nobel prizes will be on offer for anyone who comes up with good answers to these conundrums.

The Fed and other central banks will argue that the economic pain is necessary to avoid currently elevated inflation rates becoming embedded in their economies. However the theory that inflation is simply an extrapolation of past inflation is inconsistent with economic rationality and without evidence to support it. Supply side shocks, for example an oil or gas embargo, that can cause the CPI to rise, are temporary. They pass through unless more money is created to sustain demand at higher prices.

Inflation can only perpetuate itself when the supplies of money and credit are allowed to increase continuously in response to higher prices (whatever their cause). We then understandably expect them to carry on doing so to sustain higher rates of inflation. This is the case in many countries where printing money to fund government expenditure becomes an expected norm. This is not (yet) the case in Europe or the US, where the money supply is already in decline and where demand has already weakened enough to take the demand-side pressure off prices.  The market appears to recognise this even though the central banks appear not to. An inflation reality check is on the way; the sooner the better.
