The average long-term U.S. mortgage rate rose again this week, reaching its highest level in nine months, another setback for prospective homebuyers.

The benchmark 30-year fixed rate mortgage rate rose to 6.53% from 6.51% last week, mortgage buyer Freddie Mac said Thursday. Despite the latest increase, the average rate remains below 6.89%, where it was a year ago.

When mortgage rates rise they can add hundreds of dollars a month in costs for borrowers, reducing their purchasing power.

Rates have been mostly trending higher since the war with Iran began, disrupting the passage of tankers ferrying crude oil from the Persian Gulf to customers worldwide. That’s sent oil prices sharply higher — a key driver of inflation.

Mortgage rates are influenced by several factors, from the Federal Reserve’s interest rate policy decisions to bond market investors’ expectations for the economy and inflation. They generally follow the trajectory of the 10-year Treasury yield, which lenders use as a guide to pricing home loans.

Expectations of higher oil prices have pushed up long-term bond yields, causing mortgage rates to head higher.
