US inflation falls below 3% for the first time since 2021
Backfilled context carries a typed causal-confidence label and never claims a confirmed driver without human-attached evidence — a single reviewed reference establishes chronology, not causation.
What happened
The CPI report released on 14 August 2024 showed US year-over-year headline inflation below 3% for the first time since 2021, marking a milestone in the disinflation from the 2022 peak above 9%.
What was known then
At the time, disinflation had been in train for two years but progress had repeatedly stalled; this release landed weeks before the September FOMC meeting, with markets debating the size of an expected first cut.
Market reaction
The release reinforced rate-cut expectations already building after the early-August volatility episode; front-end yields and rate futures continued pricing a September start to easing.
What was uncertain
Whether shelter and services inflation would keep cooling, whether the labour-market softening visible that summer would deepen, and how large the Fed's first move would be.
What changed afterward
The September 2024 rate cut followed, and sub-3% headline inflation became the baseline against which later tariff-era inflation risk was measured.
Why it still matters
CPI release days remain among the most-read briefs we publish; this milestone explains the level framework ("back below 3%", "tariff pass-through vs the 2% goal") that current CPI coverage builds on.

Latest developments
Current coverage that genuinely overlaps this episode — nothing is linked for the sake of linking.
The Bank of Japan's published highlights of its July 2026 Outlook for Economic Activity and Prices project CPI inflation clearly above 2 percent from the second half of fiscal 2026 — on semiconductor prices, yen depreciation and crude oil — before moving toward around 2 percent through fiscal 2028. The Bank states it will continue to raise the policy interest rate in response to economic, price and financial developments.
The Monetary Policy Committee voted 6–3 on July 29 to maintain Bank Rate at 3.75%; Megan Greene, Catherine L Mann and Huw Pill preferred an increase to 4%. CPI inflation has fallen to 2.6%, but the Committee expects it to rise later this year as higher energy prices pass through, and judges the risks to the inflation outlook tilted to the upside.
Minutes of the July 28–29 FOMC meeting, released August 19, record that most participants supported holding the target range at 3-1/2 to 3-3/4 percent while several favored a 25 basis point increase. Many participants assessed that policy tightening would likely be necessary if inflation did not decline, and participants judged inflation risks as skewed to the upside.
The Federal Open Market Committee kept the federal funds target range at 3-1/2 to 3-3/4 percent on July 29. Three of twelve voters — Beth M. Hammack, Neel Kashkari and Lorie K. Logan — dissented, preferring a quarter-point increase. The statement says inflation remains elevated relative to the 2 percent goal, partly on energy supply shocks, and repeats that the Committee "will deliver price stability".
