Inflation snaps back to 3.5% as the energy shock unwinds

June’s Consumer Price Index fell 0.4% on the month, seasonally adjusted, pulling the annual rate down from 4.2% to 3.5% in a single print. The driver was the same one that caused the spike, now in reverse. Gasoline dropped 9.7% in June alone as the reopened Strait of Hormuz let crude retrace. Energy is still up 15.7% over the year, so the shock has not left the year-over-year math, but the direction has turned decisively.

The quieter story is the core. Excluding food and energy, prices rose 2.6% over the year, down from 2.9% in May. Shelter rose just 0.1% on the month, the smallest one-month change for that index since January 2021. The categories the Fed watches for persistence are holding, and they are also improving.

The round trip, by category

A supply shock that unwinds in one month rewards the patient. It also rebukes anyone who repriced their balance sheet at the top.

What it means after the 9–3

The July 29 FOMC held at 3.50–3.75% with three dissents for a hike, and those votes were cast with this CPI report in hand. That tension defines the second half. The headline is falling fast and the core is at 2.6%, yet a bloc of the committee reads the energy episode as a warning about inflation expectations rather than a passing distortion. For banks, the practical read is that the bar for a near-term cut is higher than the improving data alone would suggest.

Deposit and lending behavior will normalize on the same lag as pump prices. The transaction-pattern noise that energy stress pushed into AML monitoring this spring should recede over the summer. That is exactly when thresholds tuned to the stressed baseline start over-alerting in the other direction.
