Inflation surges 7% in December, highest rate in 40 years

Inflation rose at the fastest pace in nearly four decades in December, as rapid price gains fueled consumer fears about the economy and sent President Biden's approval rating tumbling.

The consumer price index rose 7% in December from a year ago, according to a new Labor Department report released Wednesday, marking the fastest increase since June 1982, when inflation hit 7.1%. The CPI – which measures a bevy of goods ranging from gasoline and health care to groceries and rents – jumped 0.5% in the one-month period from November.
