On Wednesday September 16, the Federal Open Market Committee raised the federal funds target range by a quarter point, to 3.75% to 4.00%. It is the first increase since July 2023, ending a cutting cycle that ran from September 2024 through December 2025. The vote was 12 to 0.
Eight weeks earlier the same committee had held rates steady with three members dissenting in favor of a hike. This time nobody dissented at all.
Two days later, Freddie Mac’s weekly lender survey put the average 30-year fixed mortgage at 6.95% - the highest weekly reading since January 2025.
Update, October 14, 2026. Mortgage rates kept climbing after this decision. Freddie Mac’s survey rose three more weeks in a row - 7.03%, 7.28%, then 7.40% for the week ending October 8 - the highest 30-year average since November 2023, with the 15-year at 6.73%. The Fed’s target range is unchanged at 3.75%-4.00%, and its next decision is October 27-28. On this post’s $320,000 example loan, 7.40% means $2,216 a month in principal and interest, about $97 more than at 6.95%. The figures below remain an accurate record of the week of September 17, 2026; for the current 15-year versus 30-year math see 15 vs 30-year mortgage.
Here is what actually changed, what did not, and the one piece of this that most coverage gets backwards.
What the Fed actually did
Straight from the FOMC statement and implementation note:
- Target range: 3.75% to 4.00%, up a quarter point, effective September 17.
- Vote: 12-0. Unanimous.
- Interest on reserve balances: 3.90%.
- The statement’s reasoning, verbatim: “Inflation remains elevated. Today’s policy action will support a timelier return to the Committee’s 2 percent goal. The Committee will deliver price stability.”
- Chairman Warsh’s press conference framed it as a standard not being met: “We must be confident that underlying inflation is moving to our objective, clearly and at sufficient speed… Today, the FOMC decided that this standard has not been satisfied.”
The Summary of Economic Projections put the median participant at 4.1% for the federal funds rate at the end of this year - which implies the committee thinks one more quarter-point rise is likely before December. The next meeting is October 27-28, 2026.
For context, here is the full rate path from the Fed’s own series, not a summary of it:
| Date | Upper target moved |
|---|---|
| July 27, 2023 | 5.25% to 5.50% (the last hike before now) |
| Sept 19, 2024 | 5.50% to 5.00% |
| Nov 8, 2024 | 5.00% to 4.75% |
| Dec 19, 2024 | 4.75% to 4.50% |
| Sept 18, 2025 | 4.50% to 4.25% |
| Oct 30, 2025 | 4.25% to 4.00% |
| Dec 11, 2025 | 4.00% to 3.75% |
| Sept 17, 2026 | 3.75% to 4.00% |
Three years and two months between hikes. That is the part worth sitting with: an entire cutting cycle has been partially unwound in a single meeting.
The thing most coverage gets backwards
The Fed does not set your mortgage rate. It sets an overnight rate that banks charge each other. Thirty-year mortgage rates track the 10-year Treasury yield instead, because that is the horizon investors actually price a mortgage against.
This matters because the two can move in opposite directions, and frequently do. Our own August post covered exactly that case: the Fed held rates on July 29, and mortgage rates rose anyway the very next day.
This time they happened to move together, and the Treasury market did most of the work before the meeting:
- September 8: 10-year Treasury at 4.80%
- September 15: 5.00%
- September 16 (decision day): 5.01%
- September 17: 4.94%
The yield rose 0.21 points in the eight days into the meeting, then eased slightly after it. Markets had largely priced the hike in advance. The mortgage rate followed the Treasury, as it always does: 6.95% against a 4.94% 10-year is a spread of 2.01 points, almost exactly the spread we measured in July.
So the honest causal story is not “the Fed raised rates, therefore your mortgage got more expensive.” It is “the bond market repriced inflation risk, mortgages followed, and the Fed moved for the same underlying reason.”
The practical consequence: if the Fed hikes again in October and the bond market has already priced it, mortgage rates may barely move. And if inflation data softens, mortgage rates can fall even while the Fed is still raising. Do not plan a purchase around the Fed calendar.
What 6.95% costs on a real loan
A $400,000 home with 20% down is a $320,000 loan. Principal and interest only:
| Week | 30-yr rate | Monthly P&I | Lifetime interest |
|---|---|---|---|
| Feb 26, 2026 (12-month low) | 5.98% | $1,914 | $369,202 |
| Jul 30, 2026 | 6.66% | $2,056 | $420,306 |
| Sep 10, 2026 (pre-Fed) | 6.76% | $2,078 | $427,951 |
| Sep 17, 2026 (post-Fed) | 6.95% | $2,118 | $442,564 |
Two readings of that table, and you need both:
- The week-on-week move is small. From 6.76% to 6.95% is $41 more per month. No purchase decision should collapse over $41.
- The same move is large over thirty years. That $41 compounds into $14,613 of extra interest on this one loan. And against February’s 5.98% low, today’s buyer pays $204 more every month for the identical house.
Both facts are true at once. The monthly number is what you have to survive; the lifetime number is what you are actually buying.
Run your own figures - including taxes, insurance and PMI - in the mortgage calculator. Its default rate follows Freddie Mac’s latest weekly survey, so the opening estimate reflects the current market rather than last quarter’s.
The 15-year moved too, and the trade-off shifted
The 15-year fixed averaged 6.26%, up from 6.09%. On that same $320,000 loan it costs $2,745 a month against the 30-year’s $2,118, and lifetime interest falls from $442,564 to $174,190.
Something subtler also changed. The gap between the two terms widened from 0.62 to 0.69 points. Because of that - and because a higher certain rate is harder for an uncertain market to beat - the break-even return at which “take the 30-year and invest the difference” starts winning moved from 7.69% to 8.14%. At a steady 8% return, the 30-year buyer used to come out ahead; on today’s rates the 15-year buyer does.
We recomputed that whole comparison this week. The full math is in 15-year vs 30-year mortgage.
The good news: savings rates
This is the half of the story that gets buried. Banks reprice deposits upward when the Fed raises, usually with a lag of a few weeks. Top nationally available high-yield savings accounts were already paying 4.00% to 4.25% in the days after the decision, and several had moved up.
What a quarter point is actually worth, annually:
| Balance | At 4.00% | At 4.25% | Difference |
|---|---|---|---|
| $5,000 | $200 | $213 | $13 |
| $10,000 | $400 | $425 | $25 |
| $25,000 | $1,000 | $1,063 | $63 |
Modest - but it is free money for a transfer that takes ten minutes, and it is the only part of a rate rise that works in a saver’s favor. The much larger gap is between a high-yield account and a legacy big-bank savings account still paying well under 1%; that difference dwarfs anything the Fed did this month. How high-yield savings accounts work covers the mechanics, and the savings goal calculator shows what a given APY does to a target.
One caution: a promotional rate is not a rate. Several of the highest advertised numbers apply only to the first few thousand dollars, or require direct deposits, or lock for 90 days and then revert. Read what the rate is conditional on before moving money.
What did NOT change
Worth being precise, because this is where unnecessary worry comes from:
- Your existing fixed-rate mortgage. Unchanged. That is the entire point of a fixed rate.
- Existing fixed-rate car and personal loans. Unchanged.
- CDs you already hold. Locked at their original rate until maturity.
- Federal student loans. Fixed at origination. New rates are set each July from a Treasury auction, not by the FOMC.
What does move with the Fed: credit card APRs (usually within a billing cycle or two), HELOCs, variable-rate private student loans, and new loan pricing.
And here is a de-panicking number. A quarter point on a $6,000 credit card balance is about $15 a year. The Fed is not why credit card debt is expensive - a 21% APR is. If that balance is the problem, the debt payoff calculator will do far more for you than tracking FOMC meetings. On a $50,000 HELOC, though, the same quarter point is about $125 a year, and that one is worth a look.
What to actually do
- Buying a home soon: get quotes from more than one lender. 6.95% is a national average for a strong borrower profile, and on a $320,000 loan even an eighth of a point is worth a phone call. Do not wait for a Fed-driven drop that may not arrive.
- Sitting on cash: check what your savings account actually pays today. If it starts with a zero, that is the expensive problem, not the quarter point.
- Carrying variable-rate debt: this is the group genuinely affected. A fixed-rate consolidation looks better after every hike, not worse.
- Holding a fixed-rate mortgage under 5%: do nothing. You are holding an asset.
FAQ
Why did the Fed raise rates when it spent a year cutting them?
Because inflation stopped cooperating. The statement says inflation “remains elevated” while economic activity is “expanding at a solid pace” and unemployment “has changed little” - a combination that removes the labor-market reason for keeping rates low. The projections put PCE inflation at 3.7% this year against a 2% target.
Will mortgage rates keep rising?
Nobody knows, and anyone who says otherwise is guessing. Mortgage rates follow the 10-year Treasury, which follows inflation expectations, not the FOMC calendar. Within the past twelve months the weekly average fell to 5.98% and climbed to 6.95%. If a future rate drop is the only thing making a payment work, the payment does not work.
Is another hike coming in October?
The median FOMC participant projects 4.1% at the end of this year, which implies one more quarter-point rise. A projection is not a commitment, and the committee has changed course before. The next meeting is October 27-28, 2026.
Should I lock my mortgage rate now?
If you have a signed contract and the payment works at today’s rate, locking removes a risk you cannot control. If you are still shopping, a lock costs you the upside if rates fall. Neither answer is universally right, but the test is the same: decide on the payment you can afford, not the rate you hope for.
