The largest monthly jump in gas prices in six decades caused a sharp spike in inflation in March, creating major challenges for the inflation-fighters at the Federal Reserve and heightening the political hurdles for the White House.

Consumer prices rose 3.3% in March from a year earlier, the Labor Department said Friday, up sharply from just 2.4% in February and the biggest yearly increase since May 2024. On a monthly basis, prices rose 0.9% in March from February, the largest such increase in nearly four years.
