On September 6, 2026, the national average for a 30-year fixed refinance rate went up to 7.31%, according to Zillow, which is a jump of 34 basis points from last week's average of 6.97%. This marks a notable increase, climbing 19 basis points from yesterday's 7.12% average. Meanwhile, the 15-year fixed refinance rate also rose, moving up 8 basis points to 6.22%. The 5-year ARM refinance rate remained steady at 6.00%.
Mortgage Rates Today, Sept 6, 2026: 30-Year Refinance Rate Rises by 34 Basis Points
Let’s look at the current refinance rates:
| Loan Type | Today's Rate (Sept 6, 2026) | Change from Previous Day | Change from Previous Week |
|---|---|---|---|
| 30-Year Fixed Refinance | 7.31% | +19 basis points | +34 basis points |
| 15-Year Fixed Refinance | 6.22% | +8 basis points | N/A |
| 5-Year ARM Refinance | 6.00% | No change | N/A |
While current rates are still lower than the highest points we saw between 2022 and 2024, this recent jump has made fewer people refinance their homes. But, if you bought your home when rates were very high, you might still find good ways to lower your monthly payments.
What’s Pushing Rates Up?
Mortgage and refinance rates don't directly follow what the Federal Reserve does with its short-term rates. Instead, they follow the 10-year U.S. Treasury yield. A mix of big economic issues has caused a lot of selling in the bond market, which pushes yields—and so, mortgage rates—higher. Here’s what’s happening:
- Problems Between the U.S. and Iran & Higher Energy Costs: New issues between the U.S. and Iran are making oil prices jump around a lot. When oil prices go up, it makes people worry about inflation again. This makes investors demand higher returns on long-term bonds.
- National Debt Is Very High: The U.S. national debt is now over $40 trillion for the first time. Investors are worried about how this debt will be managed, which is putting constant pressure on the 10-year Treasury yield to go up. It recently hit 4.74%.
- Inflation Sticking Around: Key economic numbers still show that inflation is hard to get rid of completely. This makes it harder for the Federal Reserve to cut rates aggressively.
Important Things to Think About Before Refinancing
Refinancing your mortgage means looking at your whole financial picture. If you are thinking about changing your current loan, here are some key things to check:
- The Break-Even Point: The costs to refinance a mortgage are usually between 2% and 6% of the total loan amount. You need to figure out how many months it will take for the money you save each month on interest to cover these upfront costs. If you plan to move before you reach that break-even point, refinancing will actually cost you money.
- Are You Paying Too Much? Research from Bankrate shows that about 87% of people who bought homes between 2022 and 2025 are paying too much. On average, they are paying about $3,343 more each year (or $278 more per month) than they could be, compared to the best rates available for people like them. If your current interest rate is above 7.25%, getting a rate below 7% today could still save you a lot of money right away.
- When to Lock Your Rate: Because the bond market is very up and down right now, rates are changing a lot from week to week. Talk to your mortgage broker about when to lock in your rate. If you have time, waiting for a small dip in global or economic problems might get you a better rate. But, there's also a chance that rates could stay high for longer.
- Improving Your Credit Score and Debt-to-Income (DTI): The very best rates you see advertised are for people with excellent credit scores (usually 740 or higher) and low DTI. Checking your credit report for mistakes or paying down credit card debt before you apply can make a big difference in the rates lenders offer you.
I hope this helps you understand what's happening with mortgage rates today and what to consider if you're thinking about refinancing.
