WASHINGTON (AP) — A key inflation measure jumped in March as gas prices soared, the latest sign that the Iran war is pushing up the cost of living and delaying any interest rate cuts by the Federal Reserve.

An inflation gauge monitored by the Fed rose 0.7% in March from February, up sharply from the previous month, the Commerce Department said Thursday. Compared with a year ago, prices rose 3.5%, the biggest increase in almost three years.

Excluding the volatile food and energy categories, core inflation rose 0.3% in March from February, and it was 3.2% higher than a year earlier. The annual figure is above February’s reading of 3%.
