The National Association of Realtors (NAR) said on Monday its Pending Home Sales Index, based on signed contracts, jumped 8.1% last month, the biggest increase since June 2020. Economists polled by Reuters had forecast contracts, which become sales after a month or two, rising 1.0%.

The second straight monthly increase in contracts could see existing home sales rebounding or posting another small decline after logging their 12th straight monthly decrease in January. Contracts increased in all four regions. Pending home sales decreased 24.1% in January on a year-on-year basis.

"Home sales activity looks to be bottoming out in the first quarter of this year, before incremental improvements will occur," said NAR Chief Economist Lawrence Yun.

The housing market has been walloped by the Federal Reserve's aggressive monetary policy stance, with residential investment contracting for seven straight quarters, the longest such stretch since 2009. Despite signs the worst is over, it could take a while for the housing market to turn around.

Government data on Friday showed new home sales jumped to a 10-month high in January. But mortgage rates have resumed their ascent after robust consumer spending and labor market data as well as strong monthly inflation readings raised the prospect of the U.S. central bank hiking interest rates into the summer.

The 30-year fixed mortgage rate increased to an average of 6.50% last week from 6.32% in the prior week, according to data from mortgage finance agency Freddie Mac. The third straight weekly increase lifted the rate to a three-month high.
