US inflation drops to 3.5% in June as ceasefire cools energy prices, but renewed Iran strikes threaten reversal

The June numbers

United States consumer prices fell 0.4% in June compared to May, the first monthly decline since April 2020 and the largest in 73 months, according to the Bureau of Labor Statistics. The annual inflation rate dropped to 3.5%, down from 4.2% in May and below the 3.8% economists had forecast. The retreat was driven almost entirely by energy costs: the energy index fell 5.7% over the month, with gasoline alone down 9.7%. Electricity prices decreased 1.0%, while natural gas edged up 0.5%. Food prices rose a modest 0.2% on the month and 3% year-over-year.

Core inflation and underlying pressures

Core inflation, which strips out volatile food and energy components, rose 2.6% year-over-year in June, down from 2.9% in May. The broader energy index was still up 15.7% compared to a year earlier, though that marked a sharp deceleration from the 23.5% annual rate recorded in May. Clothing and used car prices also declined, offering consumers relief beyond the pump. Michael Metcalfe, head of macro strategy at State Street Markets, told the Associated Press the data pointed to transitory wartime inflation.

Yes, gasoline prices rose, but practically nothing else did.

The Iran ceasefire effect

The June cooldown coincided with the ceasefire between Washington and Tehran signed early in the month, which reopened the Strait of Hormuz, a chokepoint for roughly one-fifth of global crude. Oil prices, which had spiked above $80 per barrel during the conflict, retreated toward $70 before the truce. The Bureau of Labor Statistics noted that the drop in fuel costs was the primary driver of the overall index decline. Airfares and other energy-linked costs also eased, though economists cited by the AP cautioned that the reprieve had not yet triggered broad-based, sustained disinflation.

Renewed hostilities and the July outlook

The improvement may already be unravelling. In recent days the United States resumed strikes on Iran, and President Donald Trump announced a new blockade of the Strait of Hormuz. Oil prices climbed for a second consecutive day on Tuesday, flirting again with the $80 mark. The June CPI data does not capture this latest escalation, and several outlets report that economists expect prices to rebound in the coming months, potentially forcing the Federal Reserve to consider rate hikes.

The Fed's dilemma

Kevin Warsh testified before Congress for the first time as Federal Reserve chair and pledged in his opening statement that inflation would become "a thing of the past." Yet the central bank remains cautious. Inflation is still well above the Fed's 2% target, and governors are scrutinising core measures for signs that war-driven price pressures are spreading into the broader economy. A New York Fed study also flagged ongoing inflationary effects from Trump-era tariffs and AI-related spending. With the Iran conflict reigniting and energy markets tightening again, the June data may stand as a brief interlude rather than a turning point.

Inflation will be a thing of the past.
