The Fed Raised Rates. What Does That Mean for Your Mortgage?

September 17, 2026

The Federal Reserve raised its benchmark interest rate by 0.25 percentage point yesterday, moving its target range to 3.75%–4.00%.

The reason is fairly straightforward: inflation is still running higher than the Fed would like. Consumer prices increased 0.4% in August, and the Fed’s latest projections show inflation remaining above its 2% goal for now.

That may sound like an automatic increase in mortgage rates—but that is not how it works.

The Fed does not directly set mortgage rates

The federal funds rate is the short-term interest rate controlled by the Federal Reserve. It has a more direct effect on borrowing such as credit cards, home-equity lines of credit and some adjustable-rate loans.

Thirty-year fixed mortgage rates work differently. They are influenced by several factors, including:

  • Inflation and expectations about future inflation

  • Treasury yields and the mortgage-backed securities market

  • The overall strength of the economy

  • Investor expectations about future Federal Reserve decisions

  • The borrower’s credit, loan type, down payment and other qualifications

Because of this, a 0.25% Fed increase does not mean every mortgage rate immediately rises by 0.25%.

Markets often anticipate a Fed decision before it happens. The bigger reaction may come from what the Fed says about inflation and future policy—not simply the rate increase itself.

Why inflation remains important

Inflation is one of the biggest obstacles standing between today’s mortgage market and meaningfully lower rates.

When investors believe inflation will remain elevated, they generally demand higher returns on longer-term investments. That can place upward pressure on mortgage rates.

If inflation begins moving consistently toward the Fed’s 2% goal, mortgage rates could receive some relief. Until then, buyers and homeowners should expect continued day-to-day movement rather than a smooth or predictable path.

That does not mean rates will increase every day. It means economic reports, Fed comments and investor expectations can continue moving rates in either direction.

What should Charleston-area buyers do?

Trying to perfectly time the mortgage market can leave a buyer sitting on the sidelines indefinitely.

A better approach is to begin with a monthly payment you can comfortably afford. From there, we can compare loan programs, estimated closing costs and different combinations of interest rates and points.

Depending on the property and the terms of the offer, buyers may also be able to negotiate seller-paid closing costs or funds toward an interest-rate buydown. Those options must be evaluated individually, but they can sometimes make a larger immediate difference than waiting and hoping for the market to change.

Being pre-approved also allows you to act when the right Charleston-area home becomes available. It does not obligate you to buy, and it gives you a much clearer understanding of your actual price range.

What does this mean for current homeowners?

If you already have a fixed-rate mortgage, the Fed’s decision does not change your interest rate or your scheduled principal-and-interest payment.

Your total housing payment could still change because of property taxes or homeowners insurance, but that would be unrelated to the Fed’s decision.

Homeowners with a HELOC or another variable-rate account may feel the effects more directly because those rates are commonly tied to the prime rate or another short-term benchmark.

If you are considering refinancing, the decision should be based on more than the advertised interest rate. We need to compare:

  • Your current rate and remaining loan balance

  • The proposed new payment

  • Closing costs

  • How long you expect to keep the loan or home

  • The time required to recover the cost of refinancing

  • Whether you are shortening, extending or otherwise changing the loan

A refinance can still make sense for some homeowners, especially when consolidating debt, changing loan terms or accessing equity. It simply needs to solve a specific financial problem.

The bottom line

The headline may sound dramatic, but the practical advice has not changed.

Understand your options. Work from a realistic monthly payment. Make decisions based on your household rather than trying to react to every economic headline.

The perfect market is rarely obvious while we are living through it. The right time to buy or refinance depends much more on your finances, your plans and the actual numbers in front of you.

If you would like help reviewing a purchase, refinance or home-equity scenario, I’m happy to work through the numbers with you—without pressure or guesswork.
