Mortgage Rates Today, September 1, 2026: Fed Hike Odds Rise to 64% as New Pressure Builds

Mortgage rates are starting September near 6.7%, and a sharp jump in Federal Reserve rate-hike bets is adding new pressure just as home buyers hoped borrowing costs might ease. Fed funds futures were pricing about a 64% chance of a September rate increase on August 31, up from roughly 35% before Federal Reserve Chair Kevin Warsh spoke at Jackson Hole on August 28.

The latest daily national figures available heading into September 1 showed the average 30-year fixed mortgage at 6.73% and the 15-year fixed at 6.08%, according to Bankrate rates. Freddie Mac’s latest weekly survey, released August 27, put the 30-year average at 6.66% and the 15-year average at 5.98%. The two measures use different methods, so actual lender offers can be higher or lower.

Freddie Mac’s 30-year average was 6.65% one week earlier and 6.56% a year ago. That means borrowers are still dealing with rates close to the highest levels seen this summer, even after several periods when falling bond yields briefly gave buyers hope of lower borrowing costs.

Mortgage rates do not move only when the Fed changes its own interest rate. Fixed home-loan rates are heavily influenced by the bond market, including longer-term Treasury yields and mortgage-backed securities. That is why buyers watching rates should also pay close attention to the 10-year Treasury.

On August 31, the benchmark 10-year Treasury yield climbed to about 4.764%, its highest level since January 15, 2025, according to a Reuters market report. Higher long-term yields can make mortgage funding more expensive and create pressure for lenders to raise rates offered to borrowers.

The latest move followed a much stronger warning on inflation from Warsh. In his official Warsh speech at Jackson Hole, the Fed chair said policymakers must be confident that underlying inflation is moving toward the central bank’s 2% goal clearly and fast enough. “Otherwise, we have work to do,” he said.

Markets reacted quickly. The estimated chance of a September hike rose to about 60% on Friday from 35% before the speech. By Monday, August 31, futures markets were pricing the odds at about 64%. That does not mean a rate increase is certain, but it shows how much the outlook changed in only a few days.

The Fed had kept its target rate at 3.5% to 3.75% at its July 29 meeting. But that decision was not unanimous. Three policymakers wanted the central bank to raise rates by a quarter percentage point instead, according to the official Fed statement.

Inflation is the main reason another hike is being discussed. The latest BEA inflation data showed the PCE price index rose 3.7% from a year earlier in July. Core PCE, which removes food and energy, increased 3.3%. Both remain well above the Fed’s 2% inflation goal.

Energy prices are creating another risk. U.S. crude rose 2.54% to $85.51 a barrel on August 31, while Brent crude climbed to $90.34 as renewed fighting between the United States and Iran increased worries about energy supplies and inflation. Higher energy costs can spread into transportation, production and household prices.

For mortgage borrowers, however, a Fed hike is not guaranteed and mortgage rates are not certain to rise in a straight line. A weak labor report or cooler inflation reading could pull Treasury yields and rate-hike expectations lower. Strong economic data or another rise in inflation could have the opposite effect.

The next major test arrives quickly. The official BLS calendar shows the August jobs report is due September 4. Producer inflation follows September 10, and the August Consumer Price Index is scheduled for September 11. The Fed then meets September 15 and 16, with its next rate decision due September 16.

Buyers should also remember that a national mortgage average is not the same as the rate an individual borrower will receive. Credit score, down payment, loan size, property type, points, debt and lender fees can all affect the final offer.

The pressure is hitting a housing market that is already struggling with affordability. New single-family home sales fell 10.5% in July to a seasonally adjusted annual rate of 607,000, according to official Census housing data. The median price of a new home sold in July was $393,800.

Mortgage rates have also moved sharply with Treasury-market changes this year. Earlier government action in the bond market temporarily helped ease borrowing costs, as explained in Investozora News’ report on the recent Treasury action. But the latest rise in yields shows how quickly inflation fears and Fed expectations can change the picture.

That volatility is also why borrowers should avoid assuming one good day means a lasting decline. Rates moved back toward their summer high as bond-market pressure returned, and the coming jobs and inflation reports could produce another fast move in either direction.

For people deciding whether to lock a mortgage rate now, the key question is not simply whether rates might fall later. Buyers should focus on whether the current payment fits their budget and how much risk they are willing to take while waiting. A strong quote may be worth locking for someone who needs certainty, while a buyer with more time may choose to watch the next economic reports.

The mortgage-rate story entering September is now centered on three forces: Treasury yields, inflation and the Fed’s September decision. With 30-year rates still around the high-6% range and markets now leaning toward another rate hike, home buyers are starting the month with more interest-rate pressure than they faced only days ago.
