Iran, oil and a hawkish Fed: rates will rise, veteran warns

Oil prices, not the Fed's new communication style, are steering mortgage rates higher

Iran, oil and a hawkish Fed: rates will rise, veteran warns

The Federal Reserve voted unanimously on June 17, 2026 to hold its benchmark rate in a range of 3.5% to 3.75% — a decision that offered the mortgage market little comfort.

For Melissa Cohn, regional vice president of William Raveis Mortgage and a 44-year industry veteran, the minutes from that meeting confirmed what bond markets were already signaling. The Iran conflict, not Fed rhetoric, is the dominant force driving mortgage rates.

"Bonds are reacting more to the renewed military action in Iran," Cohn said in commentary on the June 16-17 Federal Open Market Committee (FOMC) meeting.

"The Fed's change in communication has not moved bond yields or mortgage rates. Right now, mortgage rates are going to move with oil prices, and oil prices are increasing, so rates will rise as well. Until there is a better resolution with Iran, we are stuck in a higher-for-longer rate environment."

A new chair, the same dual mandate

Kevin Warsh assumed leadership of the Federal Reserve earlier in 2026, and the June FOMC meeting was the clearest expression yet of his more hawkish communication approach.

Warsh described the rate hold as "unanimous and unambiguous," while the updated dot plot indicated that a rate hike, once considered implausible, is now being openly discussed inside the central bank.

For brokers and loan officers trying to parse what the change in Fed leadership means for their pipelines, Cohn offered a measured take.

"The Fed will continue its dual mandate of keeping inflation low and employment at maximum capacity. That has not changed. What has changed is the communication style and guidance from the Fed."

In February 2026, the 30-year fixed rate had dipped as low as 6.09%, before rising back above 6.25% in March and climbing further to the 6.5% range by June as inflation and geopolitical pressures built.

The collapse of a fragile US-Iran ceasefire pushed rates back toward that level again in July: the 30-year fixed-rate mortgage averaged 6.49% for the week ending July 9, according to Freddie Mac's Primary Mortgage Market Survey. 

The bond market is watching oil, not the Fed

The mechanism Cohn points to is direct: the 10-year Treasury yield, which lenders use as the primary benchmark for pricing home loans, has responded far more sharply to oil price movements than to anything coming out of the Fed's press conferences.

"Mortgage rates move up and down with the 10-year bond yield. Bonds are inflation-sensitive," Cohn explained.

"The initial reaction in the bond market and in resulting mortgage rate movements may be upward, but if the Fed is strident in its goal of bringing inflation back down to 2%, that will ultimately be good for mortgage rates."

The Consumer Price Index jumped to 4.2% in May 2026, the highest reading since 2023, driven in part by oil price shocks linked to the Iran conflict. 

The Mortgage Bankers Association (MBA) is forecasting that the 30-year fixed rate will remain in the 6.1%–6.3% range through the rest of 2026, assuming inflation moderates gradually.
