US mortgage rates climbed for a third straight week, pushing home-financing costs to the highest since October and dealing a blow to both purchasing and refinancing activity.

The contract rate on a 30-year mortgage rose 13 basis points to 6.43% in the week ended March 20, according to Mortgage Bankers Association data released Wednesday. In the last three weeks, the rate has climbed 34 basis points, the most since November 2024.
