U.S. June CPI came in at 3.5% year-on-year with the first month-on-month decline since 2020, undershooting forecasts across the board — yet rebounding oil prices and sticky core inflation leave the Fed's rate-hike question unresolved.

01

How cool was this print, really?

June headline CPI rose 3.5% year-on-year, below the 3.8% consensus and down sharply from May's 4.2%.
Month-on-month, CPI fell 0.4% — the first monthly decline since 2020. The Street expected just −0.1%.
Core CPI — stripping out food and energy — came in at 2.6% y/y, below the 2.9% forecast; m/m was flat versus an expected +0.2%.
This means → headline and core both undershot. The cooling was broader and deeper than anyone priced in.
02

Why did inflation drop so sharply?

The main driver was falling energy prices. Per the Wall Street Journal, oil surged after the U.S.–Iran conflict erupted, then retreated in June as tensions temporarily eased, pulling the headline number down.
In plain terms = this round of cooling was mostly oil coming off a spike — not everything getting cheaper.
But the ceasefire has already collapsed and fighting has resumed. U.S. benchmark crude is up roughly 12% since early July. This means → the energy "dividend" may prove short-lived.
03

What is still getting more expensive?

June airfares surged 26.5% year-on-year, standing out sharply against the broader CPI decline.
Per the Wall Street Journal, economists remain cautious on core inflation's trajectory. Ongoing AI-infrastructure spending and the pass-through of tariff policy are seen as deep-seated reasons inflation pressure may not fully fade even as oil retreats.
This reflects a split picture: oil dragged the headline down, but services and structural cost pressures are still pushing back.
04

Will the Fed still raise rates?

Before the print, Fed Governor Chris Waller signaled strongly on Monday that he would back an immediate hike this month if core CPI failed to cool. CME FedWatch showed July hike odds jumping from roughly 8% to 42%.
After the print, rate-hike expectations retreated sharply. Per CoinDesk, the softer-than-expected CPI cut bets on a near-term hike.
In plain terms = this data buys the Fed a reason to hold — but not a reason to relax.
05

What comes next?

Fed Chair Kevin Warsh is set to testify before Congress roughly 90 minutes after the data release. He has stressed the need to curb inflation but has not specified the next move.
The inflation gauge the Fed watches most closely — the PCE price index (Personal Consumption Expenditures, measuring the price changes consumers actually feel) — stood at 4.1% in May, far above the 2% policy target.
June PCE data will not land until after the Fed's meeting later this month. This means → the decisive exam paper has not been handed in yet; today's CPI is only the practice test.
