Covid Inflation (2021–2023)
The 2021–2023 inflation surge, peaking at 9.1% US CPI in June 2022, came from a pandemic supply shock layered on top of large fiscal and monetary stimulus; how much was supply versus demand is genuinely contested.
| Peak CPI inflation | 9.1% (Jun 2022) |
|---|---|
| Fed funds peak | 5.25–5.50% (2023) |
| Outcome | Disinflation with a soft landing |
The post-pandemic surge was the highest US inflation in four decades, and it is the clearest recent example of supply and demand forces arriving together.
On the supply side, the pandemic snarled supply chains and, later, energy markets. On the demand side, large stimulus (notably the American Rescue Plan) plus very easy money met a reopening economy. CPI inflation peaked at 9.1% in June 2022.
This is the heart of the demand-pull vs cost-push debate. "Team Persistent" (Summers, Blanchard) emphasized overheating demand; the early Fed and others emphasized transitory supply effects. The synthesis (Bernanke & Blanchard, 2023–24) is that it was supply-shock-led early and sustained more by demand and a tight labor market later. The Fed then hiked rates to 5.25–5.50%, and because long-run expectations stayed anchored, inflation came down with far less unemployment than the 1980s, a soft landing.
