Why Are Refinance Rates Going Up?

Several factors are behind these changes. Mainly, it boils down to how the economy is doing overall and how the market is interpreting what the Federal Reserve is doing.

The Link Between Treasury Yields and Mortgages

One really important thing to consider is the connection between the 10-year Treasury yield and mortgage rates. Lenders use the 10-year Treasury yield as a benchmark for pricing 30-year mortgages. This is because the average homeowner will hold a mortgage for that long. Lately, the volatility in the market added to the risk during mortgage rate pricing, which causes some pressure.

The Fed's Role and Recent Rate Cut

The Federal Reserve just made its first interest rate cut of 2025, bringing its target range down to 4.0%-4.25%. Sounds like good news, right? Usually, when the Fed cuts rates, it has a cooling effect on mortgage rates.

Not So Fast – The Whole Story

Even though the Fed lowered rates, which helps bring down Treasury yields, mortgage rates haven't dropped as much. This is due to stubborn inflation and risk from market volatility.

Stubborn Inflation Complicates Things

The problem? Inflation is still hanging around and is above the Fed's goal of 2%. The core PCE price index, which the Fed pays close attention to, was still at 2.9% year-over-year in August. This means the Fed has to be careful about cutting rates too much, because they don't want inflation to get going again.

How the “Spread” Impacts Mortgage Rates

Now, here's where things get a little tricky, but stick with me — it's important to understand. Mortgage rates are usually higher than the 10-year Treasury yield, and that difference is called a “spread.” This spread covers the extra risk that lenders are taking on.

Typical vs. Current Spread

Usually, this spread is around 1-2 percentage points between the 10-year Treasury yield and the mortgage rates. Currently, this spread has gone up to over 2 percentage points.

What Does This Mean for Homeowners?

So, how does all of this affect you as a homeowner?

Refinancing Considerations

• Think About Refinancing? If you're stuck with a mortgage rate that's higher than the current average, it might still be worth looking into your options. But be sure to think about the costs involved and how long you plan to stay in your home.
• Keep an Eye on the Market: Mortgage rates can change quickly, based on economic news and what the Fed is doing. Staying informed can help you make the right choice.
• Shop Around: Don't just take the first offer you get. Get quotes from a few different lenders to make sure you're getting the best possible rate and terms.

Should You Still Refinance?

Deciding whether to refinance always takes some careful thought. Here's the most important thing to remember:

Crunch the Numbers!

Calculate how much you could save based on the current refinance rates, and then compare that to the expenses of refinancing (like appraisal fees and origination fees). Figure out how many months it will take for you to break even.

Looking Ahead: What to Watch For

Where mortgage rates go from here depends on a few key things:

Key Factors to Watch

• Inflation Data: Watch for upcoming inflation reports (PCE and CPI). If inflation keeps cooling down, the Fed might feel more comfortable cutting rates further.
• Labor Market: If the job market starts to slow down, that could also push the Fed to loosen things up.
• Treasury Yield Spread: If the spread between Treasury yields and mortgage rates goes back to normal, that would be great news for borrowers.

My Opinion

Personally, I think we're in a tricky time. The Fed is trying to balance inflation with keeping the economy growing. That means mortgage rates will probably be up and down for a while. Don't get discouraged, just stay in the know.

Final Thoughts

Mortgage rates today change all the time, and understanding why they're going up or down is important, whether you're thinking about refinancing or buying a home. This market is a bit of a puzzle!
