# The Fed Just Raised Rates — Why Your Quote Didn't Move By Cary Tennis (@carytennis) · Published 2026-09-18 Canonical: https://voce.com/@carytennis/fed-raised-rates-quote-didn-move-i10qyz --- On Wednesday, September 16, the Fed raised its rate — and mortgage rates didn't move. Not a tick. The 30-year fixed closed the week at **6.95%**, essentially where it was before the announcement, because the market had already priced the hike in weeks earlier (Freddie Mac). The rate I quote you doesn't track the Fed's overnight number at all; it tracks the **10-year Treasury yield**. Here's how the bond market beat the Fed to your quote. #### Key Takeaways - The Fed sets the overnight federal funds rate, not the 30-year fixed mortgage rate. - Fixed mortgage rates track the 10-year Treasury yield, plus a spread covering prepayment and credit risk. - The bond market front-runs the Fed, so by announcement day the expected move is already priced into your rate. - History shows mortgages often move opposite to Fed cuts and hikes — watch the 10-year, not the Fed. ## The Fed doesn't set mortgage rates This is the single most misunderstood thing in my business, so let's be precise about it. The federal funds rate is the rate banks charge each other for overnight loans of reserves. Overnight. One day. It is the shortest-term interest rate in the U.S. economy (Fannie Mae). Your mortgage is a 30-year loan. Those two things sit at opposite ends of the time spectrum, and they are priced by completely different forces. The Fed directly controls the overnight rate with near-perfect precision. Its influence weakens the further you go out on the maturity curve. Things that do move with the fed funds rate, usually within days or a couple of billing cycles: credit card APRs, home equity lines of credit (HELOCs), auto loans, adjustable-rate mortgages after their fixed period ends, and savings account and CD yields. Things that don't: the 30-year fixed-rate mortgage. ![10-year Treasury yield chart 2026](https://convex.voce.com/api/storage/a782aae3-092d-431d-bd02-2958bd7f44d2) ## What's in the spread The gap between the 30-year mortgage rate and the 10-year Treasury yield typically runs about 1.5 to 2 percentage points (Bankrate). Right now it's about 1.94 points — a 6.95% mortgage against a 10-year yield that closed at 5.01% on September 16. That spread isn't arbitrary. Research from the Boston Fed breaks it into real, priceable components (Boston Fed). The guarantee fee covers Fannie/Freddie protection against borrower default — roughly 42 basis points. Intermediation costs cover origination, packaging, and selling the loan. Prepayment risk compensates investors because borrowers can refinance anytime with no penalty, so they absorb reinvestment risk. And cash-flow differences matter because a Treasury returns principal in one lump sum while an MBS dribbles it back monthly. Prepayment risk cuts both ways. When rates are expected to fall, refinancing becomes more likely, the prepayment option gets more valuable, and mortgage rates rise relative to Treasuries. That's part of why a dovish Fed doesn't automatically mean cheap mortgages. The spread is also far from stable. It exceeded 300 basis points during the 2007–2009 financial crisis, compressed to under 100 basis points in 2021, and widened back to roughly 3 points through much of 2023 and 2024 (Boston Fed, Bankrate). A borrower can face a higher mortgage rate with an unchanged Treasury yield purely because the spread widened. ## The real reason there's no lag: the market moves first People assume the sequence is: Fed acts → time passes → mortgage rates adjust. A delayed transmission. That's backwards. The bond market doesn't wait for the Fed. It front-runs the Fed. Traders spend months handicapping what the Fed will do. By the time a decision is announced, the expected portion is already baked into Treasury yields and MBS prices. Research on this is blunt: revisions in expectations about future fed funds rates show up immediately in long-term mortgage rates, and the Fed can only move mortgage rates by doing something the market didn't expect (NBER working paper). So the lag isn't the market being slow. The move already happened — you just didn't see a headline about it at the time. Markets had priced in a better-than-90% chance of Wednesday's hike before the meeting (CNBC). A hike that certain is worth almost nothing in new information. ## Four times the evidence proved it **1\. Rates kept climbing after the Fed stopped (2023).** The Fed's last hike of the previous cycle was July 26, 2023, bringing the range to 5.25%–5.50% — the 11th increase since March 2022 (Federal Reserve, Bankrate). The 30-year fixed was around 6.78% that week. Then the Fed did nothing for 14 months. Mortgage rates kept rising anyway, hitting 7.79% on October 26, 2023 — the highest since 2000, and three full months after the Fed's final hike (Freddie Mac). **2\. Rates fell a full point before the first cut (2024).** The Fed's first cut came September 18, 2024 — a half point. But by the week of September 19, 2024, the 30-year fixed had already dropped to 6.09%, down from 7.79%, on anticipation alone. Industry analysts said so explicitly at the time: the decline was not due to Wednesday's 50 bps rate cut but rather to market expectations (Realtor.com). Borrowers who waited for the Fed to cut before locking missed the entire rally. **3\. The Fed cut a full point and mortgage rates went up (2024–25).** This is the example I use with every skeptical client. Between September and December 2024, the Fed cut three times, taking the effective fed funds rate from 5.33% down to 4.33% — a full percentage point of easing. Over that same stretch, the 30-year fixed mortgage rate rose from 6.09% to 7.04% by mid-January 2025. The Fed cut a point. Mortgage rates rose nearly a point. In the same window. Why? Stronger-than-expected jobs and retail data, stickier inflation, election-related fiscal concerns, and a repricing of how much easing was actually coming pushed the 10-year Treasury yield higher (CNN). The Atlanta Fed noted that the assumed link between the two rates had been turned on its head (Atlanta Fed). **4\. And now, 2026: the hike arrived after the damage.** Mortgage rates bottomed at 5.98% in late February 2026. Since then, with the fed funds rate sitting perfectly still at 3.63%, the 30-year fixed climbed steadily to 6.95% for the week ending September 17, 2026 (Freddie Mac). Nearly a full point of increase — with zero Fed action. What drove it: the 10-year Treasury yield pushed above 5% for the first time since 2023, hitting its highest level in roughly 19 years, on oil-driven inflation from the conflict in Iran and a global bond selloff (CNBC, The Hill). The 19-basis-point weekly jump to 6.95% was the biggest one-week increase since April 2025 — and it happened in the survey window before the Fed's decision. **The scoreboard since the Fed's last hike.** From July 2023 through mid-September 2026 — 165 weekly Freddie Mac readings — the 30-year fixed sat at roughly 6.78% at the time of the July 2023 hike, peaked at 7.79% on October 26, 2023, bottomed at 5.98% on February 26, 2026, and closed at 6.95% on September 17, 2026, averaging 6.68% across the stretch with a total range of 1.81 percentage points. Over that same window the Fed moved its rate from 5.375% down to 3.625% and now back to 3.875%. Mortgage rates traveled a completely different path with completely different timing. ## What this means if you're buying or refinancing Don't wait for a Fed meeting to lock. By announcement day, the expected outcome is already in your rate. Waiting for the official news usually means locking after the market has moved, not before. Watch the 10-year Treasury, not the Fed. It's published daily and free. If the 10-year is rising, expect mortgage rates to follow within a day or two. That's your actual leading indicator. Understand what a Fed cut will and won't do for you. It will lower your HELOC and credit card rates fairly quickly. It may do nothing for your 30-year fixed quote — and history shows it can coincide with that rate going up. Inflation expectations are the real driver. Long-term bond investors care about what a dollar will be worth in ten years. Persistent inflation keeps long rates elevated regardless of what the overnight rate does. A rate you can afford today is a real rate. A forecast is not. The Fed's own projections now push the return to 2% inflation out to 2029, and 16 of 18 officials see at least one more hike this year (KPMG, CNBC). Nobody knows where rates land. **So should you refinance now or wait?** At a **6.95%** 30-year fixed, run the math on the rate you can lock today versus the payment you carry now. If the new payment saves you enough that the closing costs pay for themselves in roughly two to three years — the rule of thumb most lenders use — waiting for a lower rate to appear is speculating, not planning. Here's the structure of the decision: the bond market has already priced the Fed's hike and the inflation outlook into today's yield, so the **only** ways your quote improves are if the 10-year Treasury falls (oil pressure eases, inflation cools) or the spread compresses. Both are possible, but neither is guaranteed this cycle — and 16 of 18 Fed officials still project at least one more hike, which would likely push long rates _up_ before they come back down (CNBC). If a refinance makes sense at 6.95% today, locking it removes the risk that the next move is against you. If it barely breaks even, the honest answer is to wait and watch the 10-year — and either way, don't anchor your timing to the Fed's calendar. ## The bottom line When the Fed moves, the impact on mortgage rates isn't delayed. It's usually already spent. The Fed controls an overnight rate. Your mortgage is priced off a 10-year bond, plus a spread that reflects prepayment risk, credit guarantees, and lender costs — and that bond market prices tomorrow's Fed decisions today. Anyone quoting you a mortgage rate because the Fed just moved is telling you a story about the wrong number. Have questions about how current rates affect your specific scenario?
