WASHINGTON (AP) — American consumers faced a third straight monthly surge in prices in June, the latest evidence that a rapid reopening of the economy is fueling pent-up spending for goods and services that in many cases remain in short supply.

Tuesday’s report from the Labor Department showed that consumer prices in June rose 0.9% from May and 5.4% over the past year — the sharpest 12-month inflation spike since June 2008.

Excluding volatile oil and gas prices, so-called core inflation rose 4.5% in the past year, the largest increase since November 1991.

The pickup in inflation, which has coincided with the economy’s rapid recovery from the pandemic recession, has heightened concerns that the Federal Reserve might feel compelled to begin withdrawing its low-interest rate policies earlier than expected.

If so, that would risk weakening the economy and potentially derailing the recovery. Fed officials have repeatedly said, though, that they regard the surge in inflation as a temporary response to supply shortages and other short-term disruptions as the economy quickly bounces back.
