But the enormous scale of purchases during 2020 and 2021, in circumstances where the case for a substantial monetary injection was far from clear, led to concerns about its impact on inflation.

Inflation is what we now have: 5.4% in the U.S. and 2.5% in the U.K., with more to come. This acceleration of prices is more than central banks were expecting. Recently they’ve begun to backpedal on commitments to their strategy of “lower for longer,” made when low inflation was expected to continue almost indefinitely. That’s a start, but a deeper rethink of when and how to use QE is called for.

The Economic Affairs Committee of the U.K.’s House of Lords, of which I’m a member, has just issued a report on the challenges of using large-scale bond purchases as an instrument of monetary policy.
