The Fed raised rates for the first time since 2023. Here is what it means for mortgages and HELOCs
The short answer
On September 16, 2026, the Federal Reserve raised its benchmark federal funds rate by a quarter point to a target range of 3.75% to 4.00%, its first increase since July 2023. The Fed does not set mortgage rates directly. Variable-rate debt tied to the prime rate, such as most HELOCs, usually rises within days, while 30-year fixed mortgage rates follow longer-term Treasury yields and market expectations.

What the Fed did
The Federal Open Market Committee voted to raise its target range by 0.25 percentage point, citing inflation that has stayed above its 2% goal and a labor market that remains solid. Updated projections released with the decision showed most officials expect one more increase before the end of 2026. It was the first rate change under Chair Kevin Warsh.
How it reaches your wallet
| Type of debt | How it reacts |
|---|---|
| HELOCs | Most are priced at the prime rate plus a margin. Prime typically moves with the Fed within a day or two, so a HELOC rate usually rises by about the same quarter point on the next billing cycle. |
| Adjustable-rate mortgages | Change only at scheduled adjustment dates, based on their index (usually SOFR). The Fed's move influences that index. |
| 30-year fixed mortgages | Follow the 10-year Treasury yield and investor demand for mortgage bonds. They often move before a Fed decision, based on what markets expect. |
| Existing fixed-rate mortgages | Do not change at all. |
A quick example for HELOC borrowers
On a $75,000 HELOC balance, a 0.25-point increase adds about $15.60 a month in interest (75,000 x 0.0025 / 12). That is small on its own, but several increases add up, and many HELOC payments jump when the draw period ends and principal repayment starts.
What you can do
- If you carry a large HELOC balance, ask your lender whether you can lock part of it at a fixed rate.
- If you are about to borrow a known amount, compare a fixed-rate home equity loan with a HELOC.
- If you are buying, focus on what you can control: credit, down payment, and comparing lenders. When to lock your rate.
Common questions
Does a Fed rate hike mean my mortgage payment goes up?
Not if you have a fixed-rate mortgage. Your rate is locked for the life of the loan. Adjustable-rate loans and HELOCs can change.
What is the prime rate now?
Many banks set prime 3 percentage points above the top of the Fed's target range. After the September 2026 increase, that puts the typical prime rate around 7%. Check your lender's current rate.
