The consumer price index, which measures a wide-ranging basket of goods and services, increased 7.9% over the past 12 months, a fresh 40-year high for the closely followed gauge, according to the Labor Department’s Bureau of Labor Statistics.

The February acceleration was the fastest pace since January1982, back when the U.S. economy confronted the twin threat of higher inflation and reduced economic growth.

Gas, groceries and shelter were the biggest contributors to the CPI gain. Auto prices eased.
