The Fed May Raise Rates Tomorrow—Does That Mean Your Mortgage Rate Is Going Up?

The Fed May Raise Rates—Does That Mean Mortgage Rates Will Go Up?

The Federal Reserve is meeting this week, and there is growing expectation that the Fed may raise interest rates.

So if you're buying a home, you might naturally think:

“If the Fed raises rates, my mortgage rate is going up too.”

Not necessarily.

This is one of the biggest misconceptions I hear about mortgage rates, so let's make it simple:

The Federal Reserve does NOT directly set mortgage rates.

The Fed absolutely influences the financial markets, and its decisions matter. But there isn't someone at the Federal Reserve deciding what rate you'll get on a 30-year mortgage.

Here's how it really works.

What Does the Federal Reserve Actually Do?

The Federal Reserve—usually just called “the Fed”—is the central bank of the United States.

One of its most important responsibilities is trying to keep the economy in balance.

The Fed pays close attention to things like inflation, jobs, consumer spending, economic growth and overall financial conditions.

When inflation stays too high, the Fed may raise interest rates to try to cool things down.

When the economy becomes too weak, the Fed may lower rates to encourage more borrowing and spending.

But here's the important part:

The rate the Fed raises or lowers isn't your mortgage rate.

So What Rate Does the Fed Control?

When you hear on the news that “the Fed raised rates,” they're generally talking about the federal funds rate.

That's a very short-term interest rate used within the banking system.

Changes in that rate can work their way through the economy and affect borrowing costs.

You may notice Fed decisions more directly with things like credit cards, home equity lines of credit and other variable-rate debt.

But a 30-year fixed mortgage works differently.

What Actually Determines Mortgage Rates?

Mortgage rates are heavily influenced by the bond market, including mortgage-backed securities.

That sounds complicated, but the basic idea isn't.

After mortgages are made, many are eventually bundled together into investments called mortgage-backed securities, or MBS.

Investors buy and sell these investments every day.

What those investors are willing to pay—and the return they demand for taking the risk—helps influence the mortgage rates available to consumers.

And investors aren't just watching the Federal Reserve.

They're watching everything: inflation, jobs reports, consumer spending, economic growth, government borrowing, global events and, very importantly, what they believe the Federal Reserve is likely to do in the future.

Here's What's Happening Right Now

The Federal Reserve is scheduled to announce its next rate decision on September 16, 2026, and a rate increase is widely expected.

But here's the perfect example of why the Fed doesn't directly control mortgage rates:

The bond market didn't wait until September 16 to react.

Investors have already been adjusting their expectations based on inflation reports, economic data and the possibility of higher Fed rates.

Long-term Treasury yields have risen, and mortgage rates have also moved higher.

In other words, the market has been reacting to what it thinks the Fed will do before the Fed actually does it.

That's an incredibly important concept for homebuyers to understand.

Think of It Like a Weather Forecast

Here's one of the easiest ways to explain it.

Imagine there's a 90% chance of a hurricane arriving tomorrow.

Do stores wait until the hurricane actually arrives before people start buying water, batteries and supplies?

Of course not.

People react to the forecast.

Financial markets work similarly.

If investors become convinced that the Fed is going to raise rates, they may start adjusting investments days or even weeks before the Fed makes the announcement.

So by the time the Fed actually raises rates, much of that move may already be “priced into” the market.

If the Fed Raises Rates Tomorrow, Could Mortgage Rates Actually FALL?

Believe it or not, yes.

This is the part that surprises most people.

Imagine the Fed raises its short-term rate by 0.25%, exactly as investors expected.

But then the Fed's comments suggest this may be a one-time increase or that future increases aren't certain.

Investors could view that as better news than they expected.

Bond markets could improve.

And mortgage rates could potentially improve along with them.

The opposite could happen too.

The Fed could raise rates by exactly the amount everyone expected but signal that more increases may be coming.

The bond market might react negatively, which could put additional upward pressure on mortgage rates.

That's why the headline “FED RAISES RATES 0.25%” doesn't automatically tell us what happened to mortgage rates.

We have to look at why they raised rates, what they said about the future and how financial markets reacted.

Why Do I Talk About the 10-Year Treasury So Much?

If you've seen my mortgage market updates, you've probably heard me talk about the 10-year Treasury yield.

There's a reason.

Mortgage rates and the 10-year Treasury often move in the same general direction because they're affected by many of the same economic forces.

But they are not directly tied together.

If the 10-year Treasury moves up 0.25%, that does NOT automatically mean mortgage rates increase 0.25%.

I like to think of the 10-year Treasury as a thermometer for the bond market.

It gives us a good idea of what's happening in the broader interest-rate environment, but it doesn't determine your exact mortgage rate.

The Fed Matters—It Just Doesn't Set Your Mortgage Rate

Here's the easiest way to remember all of this:

The Fed controls an important short-term interest rate.

The financial markets react to the Fed, inflation, jobs, economic data and expectations about what's coming next.

Those market movements affect Treasury yields and mortgage-backed securities.

And those markets help influence mortgage rates.

So yes, the Federal Reserve matters tremendously.

But the Fed does not directly set your mortgage rate.

What Should Homebuyers Do?

This is why I don't recommend trying to time a home purchase around a Federal Reserve meeting.

By the time the Fed announces its decision, mortgage markets may have already reacted.

And tomorrow's announcement isn't necessarily as important as what the Fed says about what may happen next.

Instead of trying to perfectly predict interest rates, I encourage my clients to focus on the things we can actually control:

Can you comfortably afford the payment?

Is this the right home?

What financing strategy makes the most sense?

Should you consider paying points, using a temporary buydown or negotiating seller-paid closing costs?

And if mortgage rates improve significantly later, would refinancing make financial sense?

At ALCOVA Mortgage, my goal is to help buyers understand what's happening behind the headlines instead of making one of the biggest financial decisions of their lives based on a news alert.

Because “The Fed raised rates” does not mean “the Fed raised your mortgage rate.”

Understanding that difference can make you a much more confident homebuyer.
