Today, the situation is different. Because the US Treasury and the Fed stepped in so quickly and proactively, there were actually fewer corporate bankruptcies in 2020 than in 2019. Given that bankruptcies normally rise sharply in recessions, this admittedly sounds a bit like too much good news.
But even with debt problems contained, there are still benefits from temporarily higher inflation. The most important is that the Fed needs to allow above-target inflation occasionally — if it is serious when it says it targets 2 per cent as an average. Many had begun to wonder if that was even possible. After the inflation drought of the past decade, a mild downpour is welcome. Making the Fed’s target inflation more credible should help shift up the term structure of interest rates and give the Fed more room to cut them in future.
In fact, economic theory gives very little robust guidance on whether, say, 3 per cent inflation is better than 2 per cent in normal times, so long as it remains reasonably stable and predictable. When Olivier Blanchard was IMF chief economist in 2010, he argued that inflation targets should be raised to 4 per cent.
Sustained inflation of, say, 3 per cent would also offer an opportunity to reconsider the Fed’s current 2 per cent target. This is hardly a radical idea: a few central banks such as Australia and Hungary already have a higher inflation target and others such as the Bank of Canada have considered the idea. True, as I have long argued, a far more elegant way to give central banks greater room to cut in a deep recession is to lay the groundwork properly for unconstrained negative rate policy, but I leave that to another day.
I have emphasised the positive aspects of moderately higher inflation for a few years. But there are risks. The biggest is if the open-ended expansion of government spending and transfers is not substantially (it need not be fully) offset by higher taxes. If the global cost of borrowing should rise unexpectedly, the higher cost of servicing the bigger debt load could lead to government pressure on the central bank to keep nominal rates down — risking inflation that eventually becomes severe.
For the moment, markets seem thoroughly unconcerned — almost too much so given the pervasive uncertainty around the global economy as it emerges from the pandemic. Still, at least for now, mildly elevated inflation more likely signals that things are going well than that we are doomed. There is no reason for the Fed to squash it too quickly.

Prices are rising mainly because the US economy is doing vastly better than seemed possible a year ago
