WASHINGTON, April 30(Reuters) – U.S. inflation accelerated in March as the Iran war raised gasoline prices, bolstering financial market expectations that the Federal Reserve could keep interest rates unchanged ​well into next year.

The personal consumption expenditures price index ‌jumped 0.7% last month, the largest gain since June 2022, after an unrevised 0.4% rise in February, the Commerce Department’s Bureau of Economic Analysis said on Thursday. The increase was in line with economists’ expectations.

In the 12 months through ‌March, ​PCE inflation shot up 3.5%, the biggest ⁠rise since May 2023, after ⁠increasing 2.8% in February. The data was included in the advance first-quarter GDP report also published on Thursday.

The BEA has caught up on key data releases following delays caused by last year’s ​government shutdown.

Inflation was already elevated before the war, largely because of President Donald Trump’s sweeping import duties.

The average national retail gasoline ⁠price surged 24.1% in March, data ⁠from the U.S. Energy Information Administration showed. Prices at ​the pump have continued to rise, hitting their highest level in ​nearly four years this week.

Excluding the volatile food and energy ‌components, the PCE price index rose 0.3% in March after increasing 0.4% in February. In the 12 months through March, so-called core PCE inflation advanced 3.2% following a 3.2% increase in February.

The Federal Reserve ⁠tracks the PCE price measures for its 2% inflation target. The U.S. central bank left its benchmark overnight interest rate in the 3.50%-3.75% range ⁠on Wednesday citing ‌rising inflation concerns from the conflict.

Inflation boosted consumer ⁠spending in March. Consumer spending, which accounts for ​more than ‌two-thirds of economic activity, surged 0.9% after rising ​0.6% in ⁠February. When adjusted for inflation, spending rose only 0.2% after gaining 0.3%, setting consumption and the overall economy on a slower growth trajectory heading into the second quarter.

Economists expect the economic fallout from the war to be more pronounced in the second quarter.
