What Happens to Mortgage Rates When the Fed Lowers the Prime Lending Rate?
If you’ve been watching the news, you’ve probably heard, “The Fed just lowered rates.” And right away, people start asking me, “Does that mean mortgage rates are dropping too?”
So today I want to break down exactly what really happens—because it’s not as simple as it sounds—and I’ll explain it in a way that’s easy to follow but from the perspective of someone who works in the mortgage world every day.
The Fed Doesn’t Directly Control Mortgage Rates
First, let’s clear up the number one misconception:
When the Federal Reserve lowers the prime lending rate, it does not directly lower 30-year mortgage rates.
The Fed controls something called the federal funds rate—that’s the rate banks charge each other for overnight borrowing. That number influences things like:
-
Credit card rates
-
Home equity lines of credit (HELOCs)
-
Auto loans
-
Adjustable-rate mortgages
But fixed mortgage rates—the ones most homeowners use—are tied to a totally different market.
So What Does Move Mortgage Rates?
Mortgage rates are actually driven mostly by the bond market, especially the 10-year Treasury yield.
Why?
Investors see mortgage-backed securities as long-term bonds. So when the bond market shifts—because of inflation, economic expectations, or investor confidence—mortgage rates follow.
Think of it this way:
-
Fed rate = short-term borrowing
-
Mortgage rates = long-term borrowing
Two different lanes. They influence each other, but they’re not the same road.
So Why Do People Think Fed Cuts Lower Mortgage Rates?
Because sometimes they do move in the same direction, but for different reasons.
When the Fed cuts rates, it’s usually because the economy is slowing or inflation is easing. Investors often respond to those conditions by putting more money into long-term bonds. When demand for bonds goes up, the yield (the return) goes down. And when that yield falls, mortgage rates often fall too.
It’s indirect, not automatic.
A good way to explain it:
A Fed rate cut doesn’t push mortgage rates down, but it can create the environment where they can move down.
What You Might See After a Fed Cut
Here’s what typically happens:
1. HELOCs and credit card rates:
These drop quickly, because they’re tied directly to the prime rate.
2. Adjustable-rate mortgages (ARMs):
These may adjust down depending on the specific index they follow.
3. Fixed mortgage rates:
These might fall, stay flat, or even rise—
depending on how investors feel about inflation and the economy overall.
It all comes down to expectations and the financial markets’ reaction.
What This Means for Homebuyers and Homeowners
If you’re hoping to buy or refinance, the key is this:
Don’t wait for Fed announcements—wait for what the bond market does afterward.
This is why working with a mortgage professional who tracks the market daily is so important. I can introduce you to lenders who can help you watch rates, understand the timing, and lock in the best opportunity when it shows up.
