U.S. mortgage rates climb as Treasury yields rise on inflation concerns
Mortgage rates climb again

Borrowing costs for U.S. homebuyers are rising again as higher oil prices linked to the Iran war feed inflation worries across financial markets. The increase pushes the average 30-year fixed mortgage rate to its highest level since August 2025 and adds pressure to housing demand and refinancing activity.

Highlights

  • The average 30-year fixed U.S. mortgage rate rose 9 basis points to 6.65% for the week ended May 22, its highest in nine months.
  • Mortgage applications fell 8.5% from the prior week as higher rates and weaker refinancing demand reduce borrowing activity.
  • Financial markets now price in a possible Fed rate hike by year-end, as April consumer prices rose 3.8% and inflation concerns persist.

Mortgage rate increase and policy backdrop

As reported by Mortgage Bankers Association, the average rate on a 30-year fixed mortgage rose 9 basis points to 6.65% in the week ended May 22. That is the highest level in nine months, returning above the levels seen before the Federal Reserve began cutting interest rates to counter labor market weakening.

The labor market has since stabilized, with the U.S. unemployment rate at 4.3%, the same level as last August. At the same time, inflation has accelerated, with consumer prices rising 3.8% in April from a year earlier, compared with 2.9% in August.

A growing number of Fed policymakers now say they may need to consider raising interest rates if price pressures prove persistent rather than temporary. The latest move in mortgage rates also comes as Kevin Warsh takes over as Federal Reserve chair, replacing Jerome Powell, while President Donald Trump says he expects rates to come down.

Housing demand and market implications

Higher mortgage rates are already weighing on borrowing activity. Mortgage applications fell 8.5% from the prior week, with the decline driven largely by weaker refinancing demand.

Mortgage rates are only loosely linked to the Fed's short-term policy rate and tend to track the 10-year U.S. Treasury yield more closely. Benchmark yields moved higher as elevated oil prices fueled inflation concerns, though U.S. government bond yields have fallen this week on hopes of a breakthrough deal to reopen the Strait of Hormuz.

Financial markets are now pricing in the possibility of a Fed rate hike by the end of the year, a shift that could keep pressure on housing finance costs if inflation remains elevated.

In our earlier coverage of the recent slide in U.S. Treasury yields, we noted that bond markets were reacting to shifting Middle East ceasefire prospects alongside renewed U.S.–Iran tensions. We also highlighted that investors were focused on upcoming PCE inflation data and what it could mean for the Fed’s policy path, as geopolitics and energy-driven price pressures continued to influence rate expectations.
