At noon Denver time yesterday, the Federal Reserve raised its benchmark rate for the first time since July 2023. By 12:07 I had a text from a buyer client in Highlands Ranch asking if her mortgage rate had just gone up. The honest answer was: not because of the vote. It went up about half an hour later, and for a different reason than most of the headlines are giving.
Three weeks ago I wrote that a hike was a live possibility, even though a hold looked more likely. The hike happened. Here’s what the Fed actually did, why mortgage rates reacted the way they did, and what it means if you’re buying or selling anywhere in Parker, Aurora, Castle Rock, or the south Denver suburbs this fall.
What the Fed Actually Did on September 16
The Federal Open Market Committee raised the federal funds target range by a quarter point to 3.75% to 4.00%. The vote was 12 to 0. That unanimity is the part I keep coming back to. In July, three members dissented in favor of a hike and the rest held. Two months later, nobody was holding.
The statement itself was short. “Inflation remains elevated,” it said, and the increase “will support a timelier return to the Committee’s 2 percent goal.” It described economic activity as expanding at a solid pace, with job gains keeping up with the workforce. In plain language: the Fed thinks the economy can handle higher borrowing costs, and it’s more worried about prices than about growth.
This is the first increase since the summer of 2023, and it reverses the direction most buyers have been assuming for two years. A lot of people I talk to have been “waiting for rates to come down.” Yesterday was the Fed saying, fairly clearly, that it isn’t in a hurry to help with that.
Why Mortgage Rates Moved at 12:30, Not at Noon

The federal funds rate is an overnight rate between banks. Your 30-year mortgage rate follows the bond market, mostly the 10-year Treasury and mortgage-backed securities, and bond traders had already priced in a quarter-point hike well before the announcement. So when the decision hit at noon Mountain time, mortgage bonds barely moved.
The move came at 12:30, when Fed Chair Kevin Warsh started his press conference. According to Mortgage News Daily’s same-day analysis, he described the economy as strong, said inflation hadn’t made real progress recently, and said the Fed needed to “remove some accommodation.” Traders heard “some” and concluded there’s more to remove, meaning more hikes could follow. That’s when the 10-year yield pushed toward 5% and mortgage rates had what MND called a bad day.
By the close, MND’s daily 30-year index sat at 7.24%, the highest reading since January 2025. For context, Freddie Mac’s weekly survey had the 30-year at 6.76% as of September 10, up from 6.71% the week before and from 6.35% a year ago. Freddie’s number is a weekly average of quotes for buyers with 20% down and excellent credit, so it tends to lag the daily indexes and read lower. Expect this Thursday’s print to move up, but probably not all the way to the daily figure.
One more thing the MND piece said that I agree with: a Fed that’s serious about inflation is good for mortgage rates in the long run, because long-term rates are mostly a bet on future inflation. The question is how long “the long run” takes, and nobody, including the Fed, knows that yet.
What This Does to a Payment on a Denver-Area Home
Numbers help here. The August REcolorado report put the Denver metro median closed price at $595,000. A buyer putting 20% down finances $476,000.
At last week’s 6.76%, the principal and interest payment on that loan is about $3,090 a month. If a lender is quoting closer to the daily 7.24% this week, the same loan is about $3,244. That’s roughly $150 a month, or about $1,800 a year, for a house that didn’t change price at all.
For a first-time buyer putting 5% down on a $450,000 townhome in Parker or Aurora, the loan is $427,500. The same rate move takes the payment from about $2,776 to about $2,913, a difference of around $140 a month. That doesn’t decide whether you can buy. It does decide whether the second bathroom, the bigger lot, or the shorter commute stays in the budget.
What I don’t want you to do is read “highest since January 2025” and assume the market just turned against you. The last time rates sat here, in January 2025, buyers had far fewer homes to choose from. Today you have 13,211 active listings across the metro and 18 weeks of supply, according to that same REcolorado report, a level the metro hadn’t seen in roughly a decade before this summer. Rates are higher and selection is wider. Those two things partly offset each other, and the second one is on your side.
If You’re Buying This Fall
A few things I’m doing with clients this week, in order of how often they come up.
Get a real quote, not a headline number. The 7.24% figure is an index. Your actual rate depends on your credit, your down payment, whether you pay points, and which lender you call. Two quotes on the same day can differ by a quarter point, and Freddie Mac’s own economist made the point again last week that shopping around can save thousands.
Decide your lock strategy before you write an offer. With more hikes now on the table, “wait and see” carries more risk than it did in August. I walk through the options, including float-down provisions, in my rate lock guide.
Run the buydown math. In an 18-week-supply market, sellers are paying concessions again, and a seller-paid 2-1 buydown or permanent points are often a better use of that credit than a price cut of the same size. My points and buydown guide has the breakeven math, and my seller concessions guide covers what you can actually ask for.
Ask whether the loan is assumable. Any home with an FHA or VA loan from 2020 or 2021 might carry a rate in the 3s that a qualified buyer can take over. It’s rare, it’s slow, and it’s worth asking about on every listing. Details in my assumable mortgage guide.

If You’re Selling This Fall
Higher rates thin the buyer pool a little more, and the pool was already thinner than it was in the spring. Homes were taking a median of 29 days to go under contract in August, up a full week from July. A rate move like this one usually shows up as a few fewer showings in the first weekend and a little more sensitivity to price.
That doesn’t mean you shouldn’t list. It means the first two weeks matter more than ever. Price for the buyers who are actually out there this month, not for the ones who were out there in May, and be ready to talk about concessions early instead of after the third weekend of quiet. A seller-paid buydown costs you less than most people assume and can be the thing that moves a buyer from “we’ll keep looking” to “let’s write.”
And if you’re selling and buying at the same time, this is a week to recheck your own numbers on the purchase side, because the rate you were pre-approved at in August may not be the rate you’ll close at in October.
I’ll be watching the Freddie Mac number on Thursday and the next round of inflation data closely, and I’ll update here if anything changes the picture. If you’d like to talk through what this means for your specific situation, I’m always happy to. No pressure, no pitch.
Quick answers
Did the Fed raise mortgage rates on September 16?
Not directly. The Fed raised the federal funds rate, an overnight bank rate, by a quarter point to 3.75% to 4.00%. Mortgage rates follow the bond market, and they rose later that afternoon because Chair Warsh signaled that more increases could follow.
What is the 30-year mortgage rate in Colorado right now?
Freddie Mac’s weekly survey averaged 6.76% as of September 10, 2026. Mortgage News Daily’s daily index closed at 7.24% on September 16, the highest since January 2025. Your actual quote will depend on your credit, down payment, and lender.
Should I wait for rates to drop before buying in Denver?
With the Fed now raising rates, a near-term drop looks less likely than it did in August. Denver’s 18 weeks of supply gives buyers more selection and more room to negotiate concessions like a seller-paid buydown, which can offset part of the rate increase.
