A rise in mortgage interest rates has led to a decline in people applying for home loans and homeowners refinancing.

Renewed concerns over tariffs and the broader economy drove treasury yields higher last week, and mortgage rates followed. As a result, total mortgage application volume dropped 10% last week compared with the previous week, according to the Mortgage Bankers Association's seasonally adjusted index.

The average rate on a 30-year U.S. mortgage rose for the second week in a row, another setback for the U.S. housing market, which is mired in a sales slump as affordability constraints shut out prospective homebuyers.
