The Fed's September 2026 hike did not raise your mortgage rate. It raised the overnight rate banks charge each other. Thirty-year mortgage rates are set by the bond market, which had already priced this move in, and they are now responding to inflation and energy prices more than to the Fed. The loans the hike does hit directly are the variable ones: HELOCs, credit cards, and many commercial and construction lines.
What did the Fed actually do in September 2026?
On September 16, the Federal Open Market Committee voted 12-0 to raise the federal funds rate by a quarter point, to a target range of 3.75%-4.00%. It is the first increase since July 2023. The vote was unanimous, but it was not a surprise: three members had already dissented in favor of a hike at the July meeting.
The statement read like a Fed that likes the economy but does not trust inflation. It described spending as resilient, productivity growth as strong, and capital investment as robust. It also said plainly that inflation remains elevated and that uncertainty is high, partly because of geopolitical developments. Elevated energy prices tied to the conflict in the Middle East are a big part of that story.
The committee's stated goal is to cool demand just enough to get inflation back to its 2% target without stalling growth. Most officials who submitted projections expect another increase before the end of 2026, and futures markets are pricing in a similar path.
The rate-cut cycle is over for now. If your plan for 2026 was "wait until rates drop," the Fed just told you that is not its plan.
If the Fed raised rates, why doesn't that set my mortgage rate?
The federal funds rate is what banks charge each other for overnight loans. A 30-year mortgage is a 30-year loan. Lenders price it off long-term money, mainly the 10-year Treasury yield and mortgage-backed bond prices, and those markets are driven by where investors think inflation and growth are headed over years, not one meeting.
That is why the market moves before the Fed does. By the time the committee voted, the hike was close to a sure thing, so investors had already built it into long-term rates. Look at the weeks leading up to the decision in Freddie Mac's weekly survey:
| Week ending | 30-yr fixed avg | 15-yr fixed avg |
|---|---|---|
| Sept 3, 2026 | 6.71% | 6.04% |
| Sept 10, 2026 | 6.76% | 6.09% |
| Sept 17, 2026 | 6.95% | 6.26% |
| Same week, 2025 | 6.26% | 5.41% |
Rates were drifting up for weeks as inflation data came in hot and the hike became the consensus. Here is the part people miss: during the last cutting cycle, mortgage rates did not fall anywhere near as much as the Fed cut. The connection is loose in both directions.
After more than 1,400 closings, the pattern I trust is this: nobody times rates well, including the people paid to forecast them. What I watch is inflation data and the 10-year Treasury. Headlines about the Fed usually arrive after the mortgage market has already moved.
Which loans does a Fed rate hike actually affect right away?
Anything tied to the prime rate. Most banks set prime three points above the top of the Fed's range, so it moved up a quarter point with this decision. That flows through quickly to:
- HELOCs. Most are variable and priced off prime, so your payment on an existing balance just went up.
- Credit cards and personal lines, which usually reprice within a billing cycle or two.
- Adjustable-rate mortgages at their next reset, depending on the index.
- Commercial lines, construction loans, and many business loans, which often float over prime or a short-term benchmark.
This matters out here more than people think. A lot of Western North Dakota property is owned through operating businesses: shops, yards, industrial buildings, rentals held by contractors. If you carry a floating-rate line against that real estate, this hike hit your cash flow this month, not someday.
HELOCs are still a smart way to tap equity without giving up a low first-mortgage rate. Just price them as variable debt that could rise again, not as cheap money. If a draw only works at today's rate, it does not work.
What does this mean for buying or selling property in Williston and Watford City?
The same energy prices pushing the Fed to tighten are the prices that drive activity in the Bakken. That puts our market in an unusual spot compared to most of the country. Higher borrowing costs weigh on affordability everywhere, but here they are arriving alongside an energy backdrop that historically supports jobs, rentals, and commercial demand across Williams and McKenzie counties.
For buyers, the honest math is simple: waiting for a better rate is a bet, and right now the Fed is betting against you. If prices hold or rise while rates climb, you lose on both sides of the payment. For renters, buying what you can afford now starts building equity you can use later toward the property you really want, as long as you plan to stay long enough to cover the cost of buying and selling.
For sellers, this is where rate buydowns earn their keep. A seller concession that pays discount points can permanently lower a buyer's rate, which often does more for the buyer's payment than the same dollars cut off the price. A temporary buydown (a 2-1, for example) lowers only the first years. Know which one you are offering.
For investors and commercial owners, a higher cost of debt pressures cap rates and debt coverage. Deals that penciled on the assumption of cuts need to be re-underwritten at today's rate, not next year's hoped-for rate.
As a Crexi Platinum Broker, I underwrite commercial deals at the rate you can actually get today, with a stress test above it. I tell homebuyers the same thing: buy the payment you can carry now. If rates fall later, refinance. If they don't, you are still fine.
Should I wait for mortgage rates to come down before I move?
Sometimes, yes. Waiting makes sense if you might leave the area within a few years, if your job situation is uncertain, if you do not have reserves after closing, or if the payment only works at a rate you do not have. Renting is not failing. It is a legitimate choice for the right person.
But waiting purely because you expect rates to drop is a forecast, and the people setting policy just forecast the other direction. If the property, the payment, and your timeline all work today, the rate is rarely the reason to sit out.
Get the numbers first: a real pre-approval, your actual payment at today's rate, and what that payment looks like a half point higher and a full point lower. The decision usually makes itself.
How did we get from near-zero rates to a hike?
| When | What the Fed did |
|---|---|
| March 2020 | Cut the federal funds rate to near zero |
| 2022 to July 2023 | Raised rates aggressively to fight inflation |
| Sept 2024 to Dec 2025 | Six cuts, three in each year, to 3.50%-3.75% |
| Early 2026 to July 2026 | Held steady |
| Sept 16, 2026 | Raised a quarter point to 3.75%-4.00% |

Common questions about the Fed and mortgage rates
Does the Fed set mortgage rates?
No. The Fed sets the federal funds rate, an overnight bank-to-bank rate. Fixed mortgage rates follow the bond market, especially the 10-year Treasury, which reacts to inflation and growth expectations.
Why did mortgage rates rise before the Fed hiked?
Because the hike was expected. Investors priced it in as inflation data came in above target, so long-term rates moved in the weeks before the vote rather than on the day of it.
Will mortgage rates go up again if the Fed hikes in December?
Not necessarily. If a December hike is already expected, it is largely priced in. What moves mortgage rates from here is whether inflation and energy prices surprise higher or lower than the market expects.
Did my HELOC rate just go up?
Most likely, if it is variable and tied to prime. Check your statement or lender notice for the new rate and when it takes effect.
What is a rate buydown and is it permanent?
A buydown is paying upfront, usually through discount points, to get a lower rate. A permanent buydown lowers the rate for the life of the loan; a temporary buydown like a 2-1 lowers it only for the first one or two years.
Is it a bad time to buy property in Williston?
It depends on your timeline and payment, not the Fed. If you plan to stay, can carry the payment at today's rate, and keep reserves after closing, waiting for a rate drop is a gamble with no guarantee of a payoff.
Does a Fed hike affect commercial real estate loans?
Often more directly than home loans. Many commercial, construction, and business lines float over prime or a short-term benchmark, so they reprice quickly after a Fed move.
The Fed moved one rate. Your decision depends on a different one, and on a payment, a timeline, and a property that either works today or doesn't. Get those numbers straight and the headlines stop running your plans.
