When the Federal Reserve raises interest rates, borrowing on credit cards and home equity lines gets more expensive within weeks, and savings accounts usually start paying a bit more. Mortgage rates move with long-term bond yields, not the Fed directly, but rate hikes help push them up too.
That matters now. The Fed raised its benchmark rate to 3.75%–4% on September 16, 2026, its first hike since 2023, and most officials expect at least one more by year-end.
How a Fed rate hike affects your money
| Product | What happens | How fast |
|---|---|---|
| Credit cards | Variable APRs rise with the prime rate | Usually within one or two billing cycles |
| Home equity lines (HELOCs) | Rate rises with prime | Usually next billing cycle |
| Adjustable-rate mortgages | Rate rises at next reset | At the reset date in your loan terms |
| Fixed-rate mortgages | Follow 10-year Treasury yields | Indirect; already near 7.40% |
| New car loans | Lenders charge more | Gradually |
| Existing fixed loans | No change | — |
| Savings, money market, CDs | Yields tend to rise | Gradually, varies by bank |
Why do credit card rates go up?
Most credit cards charge a variable rate pegged to the prime rate. Banks typically set prime 3 percentage points above the top of the Fed's range. So each quarter-point Fed hike adds about a quarter point to your card's APR.
On a $5,000 balance, a quarter-point increase adds only about $12.50 a year in interest. But hikes stack up. And card rates are already among the highest of any common type of borrowing.
What about mortgages?
Fixed mortgage rates follow the 10-year Treasury yield, which has been around 5.1%, the highest in years. Freddie Mac's 30-year average is 7.40%, up from 6.27% a year ago.
On a $400,000 loan, that is about $300 more a month than a year ago. See today's mortgage rates and why Treasury yields are so high.
Is it good news for savers?
Mostly. Online banks often raise yields on high-yield savings accounts and CDs after a Fed hike. Traditional banks tend to be slower.
With inflation at 3.7%, check what your savings actually pay. Many standard accounts still pay far less than inflation, meaning your money loses buying power.
Why is the Fed raising rates?
Inflation is climbing again, fueled by higher energy prices linked to the Iran war. Consumer prices rose 3.7% in the year to September, and price pressure is spreading into services.
Governor Christopher Waller said on October 8 that he anticipates "additional hikes to support a timelier return of inflation to our 2 percent goal." Analysts cited by Axios expect about 0.75 points of hikes in total, ending in early 2027.
What should you do?
- Pay down variable-rate debt first, starting with credit cards.
- Lock in fixed rates on loans you need soon, before further increases.
- Move idle cash into a higher-yield savings account or CD.
- Avoid new variable-rate borrowing unless you can repay it quickly.
- Check your ARM or HELOC terms so you know when your rate resets.
When will rates change next?
The Fed decides on October 28 and December 9. Markets lean toward a hold in October and a hike in December. Our Fed meeting guide tracks the odds.
