It is tempting to believe that, if we are diverted down the path of financial disruption by aggressive central bank tightening in 2022 and 2023, we will not arrive at our inflationary destination but instead at the ‘secular stagnation’ status quo ante.
There are three reasons to be sceptical. First, despite a massive pandemic-induced spike in inflation and the fastest rebound out of recession in post war history, to date we have seen only a paltry reduction in policy stimulus, itself the most aggressive and wide-ranging stimulus programme in peacetime history (Figure 2). So, when they next stare into a recession, central bankers will find their armoury even more depleted than was the case in early 2020. Whether made explicit or not, ‘helicopter money’ will then be the most palatable and effective tool.

The second reason relates to the economic legacy of the pandemic. People are buying different things in different ways, working in different places, using different modes of transport and living in different locations. The resulting supply side disruption will make calibrating any future policy response to financially driven economic weakness that much trickier.

The third reason is the most convincing to us. Policy interventions in the years after the Lehman collapse focused on Wall Street, not Main Street. The pandemic has revealed that sizeable and broad-based support for Main Street is the only choice voters will tolerate from their representatives. As politicians responding to the costs of Russia’s invasion of Ukraine are now discovering. this is consequential because support for Main Street can lift inflation, where stimulus aimed at Wall Street cannot.
