(Reuters) – The interest rate on the most popular U.S. home loan surged by the most in nearly two years last week, shooting above the 4% level for the first time since 2019 as financial markets anticipate that the Federal Reserve will respond to the highest inflation in a generation with an aggressive run of rate hikes.

The Mortgage Bankers Association on Wednesday said its weekly measure of the average contract rate on a 30-year, fixed-rate mortgage climbed to 4.05% in the week ended Feb. 11 from 3.83% a week earlier. That was the highest since October 2019 and the largest weekly increase since March 2020 when the onset of the coronavirus pandemic was roiling financial markets.
