What the Data Actually Shows

The Consumer Price Index (CPI), the standard measure of inflation, reached its recent peak in June 2022 at 9.1% year-over-year. [1]

This was the highest 12-month increase since November 1981 — the largest in roughly 40 years — but, as later sections show, still well below the largest inflationary spikes in U.S. history. [1]

The "Worst in History" Claim

Claims that 2021-2022 inflation was "the worst in history" are demonstrably false: the 9.1% peak was the highest in about four decades, not in the nation's history. [2]

Earlier in American history, inflation ran far hotter — the CPI rose 23.7% in the 12 months ending June 1920 after World War I, and 20.1% in the 12 months ending March 1947 after World War II. [3]

Cumulative Price Increases

A related claim involves cumulative price increases — arguing prices rose by some unprecedented total amount. Consumer prices rose about 21.5% cumulatively over the four years of the Biden administration (January 2021 to January 2025). [4]

That is a large increase for a four-year span, but it is not close to the 20%-plus inflation the country saw in a single year following each World War. [4]

Inflation in 2025

By December 2025, year-over-year inflation stood at 2.7%, matching November and continuing to run close to the Federal Reserve's 2% target. [5]

Claims made in 2025 that inflation was still at "historical" levels were especially misleading: PolitiFact rated a similar claim from President Trump that his predecessor caused "the worst inflation…in the history of our country" as Mostly False, noting the actual peak was about 9% in mid-2022. [6]

Global Context

The post-pandemic inflation surge was a global phenomenon, not unique to the United States. The U.S. had the highest inflation rate among G7 countries in the first half of 2022, but by mid-2023 it had the lowest inflation rate in the G7 and ranked among the lowest of the world's advanced economies. [7]

So while U.S. inflation was real and painful, it was neither historically unprecedented nor an outlier compared with peer economies.
