Sept 23 (Reuters) – The rate on the most popular US home loan rose last week to its highest in more than two years, ​after the Federal Reserve lifted short-term interest rates ‌to combat inflation, and rising oil prices drove up Treasury yields that underpin residential borrowing costs.

The average 30-year fixed-rate mortgage jumped 15 basis points to 7.12% in the week ended September 18, the ‌Mortgage ​Bankers Association said on Wednesday. It ⁠was last higher in ⁠May 2024.

Mortgage rates have risen more than a full percentage point since joint US-Israeli strikes against Iran began pushing up the global price of oil in late ​February, putting the squeeze on prospective homebuyers and a chill into the US housing market.

Mortgage rates track US ⁠Treasury yields, which are sensitive ⁠to oil prices and the threat they ​pose to inflation, which has been running above the Fed’s 2% ​goal for 5-1/2 years.

Last week the Fed increased ‌its policy rate by a quarter of a percentage point to the 3.75%-4.00% range to put inflation on a “timelier” path to 2%, and nearly all Fed policymakers projected ⁠at least one more rate increase by the end of this year. Traders are also betting on further Fed rate hikes.

The ⁠rise in mortgage ‌rates last week led to a decline ⁠in refinancing and home purchase applications, the ​MBA ‌said, and drove more borrowers into adjustable-rate ​mortgages, which ⁠offer lower upfront borrowing costs than fixed-rate mortgages and reset after a number of years to whatever the going rate is at the time. ARMs accounted for 9.8% of mortgage applications last week, the MBA said.
