Key U.S. inflation gauge jumped 6.6% in March — most since 1982

An inflation gauge closely tracked by the Federal Reserve surged 6.6% in March compared with a year ago, the highest 12-month jump in four decades and further evidence that spiking prices are pressuring household budgets and the health of the economy.

Yet there were signs in Friday's report from the Commerce Department that inflation might be slowing from its galloping pace and perhaps nearing a peak, at least for now.

Excluding the especially volatile food and energy categories, so-called core prices rose 5.2% in March from a year earlier. That was slightly below the 5.3% year-over-year increase in February, and it was the first time that 12-month figure has declined since February 2021, before the inflation spike began. And on a month-to-month basis, core prices rose 0.3% from February to March, the same as from January to February.
