U.S. Inflation Rises to 4.1% in May as Iran Conflict Fuels Energy Prices

The personal consumption expenditures (PCE) price index rose 0.7 % in May, bringing the year-over-year rate to 4.1 %. Excluding food and energy, core PCE increased 0.3 % month-over-month and 3.4 % over the past year. Both the headline and core rates are the highest recorded since April 2023 and the fall of 2023, respectively, and remain well above the Federal Reserve’s 2 % target.

In February, President Donald Trump and Israel launched joint strikes on Iran, prompting Tehran to close the Strait of Hormuz—one of the world’s busiest maritime trade routes. The closure sharply lifted oil and other commodity prices for several months. A bilateral agreement announced earlier this month reopened limited traffic through the strait, prompting a noticeable decline in gasoline prices, though earlier price spikes have already permeated broader consumer costs.

May’s headline PCE inflation of 4.1 % marks a 0.3 % increase from April’s 3.8 % reading, while core PCE rose from 3.3 % to 3.4 % in the same period. The upward momentum follows a pattern of accelerating price growth that began after the Iran-related supply disruptions, indicating that elevated energy and food costs are feeding into other sectors of the economy.

The Commerce Department released the May PCE figures on Thursday, confirming the latest rise. Federal Reserve officials have reiterated that inflation remains above the central bank’s preferred 2 % level, signaling continued vigilance in monetary policy despite the recent easing of gas prices. No policy shift has been announced, and the Fed’s stance continues to be guided by overall inflation trends rather than isolated commodity movements.

Analysts highlighted that the inflation surge disproportionately strains middle-income households, for whom higher energy and food bills translate into reduced purchasing power. Critics argue that the war-induced commodity spikes have accelerated cost pressures already present in the economy, raising concerns about the durability of consumer affordability and the adequacy of policy responses.

The recent reopening of the Strait of Hormuz is expected to keep gasoline prices on a downward trajectory, but the broader inflation rate may stay elevated until the effects of earlier commodity spikes fully dissipate. Federal Reserve policymakers are likely to monitor upcoming PCE releases closely before adjusting interest-rate policy, while analysts will watch global energy markets for further volatility.
