Fed Rate Hike Could Lower Mortgage Costs by Anchoring Inflation Expectations — Image: editorial illustration · Story sourced from CNBC Real Estate

The Federal Reserve will meet Sept. 15-16 under pressure from President Donald Trump and senior administration officials not to raise interest rates. Investors are pricing a 60% chance the central bank will hike its benchmark by a quarter percentage point, according to the CME Group's FedWatch tool.

The central bank has held rates unchanged all year as inflation remains well above the Fed's 2% target. Fed Chairman Kevin Warsh has curtailed forward guidance on rate moves. The September meeting comes weeks before November midterm elections, with polls showing voters dissatisfied with high prices and elevated borrowing costs.

Trump argued in a Sept. 4 post on Truth Social that the U.S. should have the lowest interest rates and that maintaining too high a federal funds rate puts the country at an economic disadvantage. He wrote that "the Fed Board, with its great new leader, must get smart — BE PATRIOTS for a change." The president has not directed attacks specifically at Warsh, as he did former Chair Jerome Powell.

Reducing rates too soon could undermine efforts to tamp down inflation, said Mark Higgins, senior vice president at Index Fund Advisors and author of "Investing in U.S. Financial History: Understanding the Past to Forecast the Future." "History demonstrates that the most reliable way to restore price stability is to maintain sufficiently restrictive monetary policy until inflation is decisively tamed," Higgins said. "Considering the duration of this inflationary episode, I believe sending a clear message via an interest rate hike is appropriate and in the best interest of the American people."

The 10-year U.S. Treasury yield briefly topped 4.8% on Tuesday as climbing oil prices fueled inflation concerns. The average rate on a 30-year fixed mortgage reached 6.89%, according to Mortgage News Daily. Fixed mortgage rates have risen from less than 6% before the war with Iran.

"The president's exhortation to the Fed to cut rates would prove counterproductive, almost surely causing already-rising long-term rates to rise substantially further," said Mark Zandi, chief economist at Moody's. Fixed mortgage rates could surge to well above 7%, he said. "Borrowing costs for businesses and commercial property owners would rise, and even the stock market would likely come under pressure."

Bond investors expecting a Fed rate hike to fight above-target inflation would be spooked by a Fed cut, Zandi said. "It would signal that the Fed has lost its independence from the president, which would mean even higher inflation in the future," he said. Preserving the Federal Reserve's credibility is what matters most, he said.

The Deployment Angle

Family offices financing property acquisitions face a choice between locking fixed-rate debt now at 6.89% or waiting for a potential Fed cut that could backfire. If the Fed holds or hikes at next week's meeting, bond markets may stabilise and long-term mortgage rates could drift lower as inflation expectations anchor. If the Fed cuts under political pressure, the 10-year Treasury yield could rise further above 4.8%, pushing 30-year mortgage rates well above 7% and repricing acquisition underwriting across office, industrial and multifamily deals.

The arithmetic matters for direct property ownership. A quarter-point Fed hike would raise short-term construction and bridge loan costs by 25 basis points, but a spooked bond market could add 50 to 100 basis points to permanent fixed-rate debt. On a $50 million acquisition financed at 65% loan-to-value, that swing translates to $325,000 to $650,000 in additional annual debt service. For portfolios holding floating-rate debt, a Fed hike increases near-term carry costs but may prevent a larger repricing of refinancing options in 2027 and 2028.

Underwrite two scenarios for any deal closing in the fourth quarter. In the hike scenario, assume 7% fixed-rate debt is available by year-end as bond yields stabilise. In the cut scenario, assume 7.5% fixed rates as inflation expectations unanchor and the Fed's credibility erodes. Price the difference into your basis and target a minimum 200-basis-point spread to the higher refinancing rate. Avoid relying on rate cuts to rescue underperforming assets — the path to lower mortgage rates runs through tighter monetary policy, not looser.

For capital deployment, favour deals with locked fixed-rate debt or fully funded equity structures over those requiring near-term refinancing or floating-rate bridge loans. If you are holding assets for sale, close before the Sept. 15-16 meeting or wait until bond markets react. The worst outcome is a Fed cut that spooks fixed-income investors and drives long-term borrowing costs higher just as you need to refinance or sell into a rising-rate environment.
