Mortgage Rates: Dancing to Their Own Beat

Why the Prime Rate isn’t the DJ

When the Federal Reserve reduces the Prime Rate, people often expect mortgage rates to drop right away. It feels like they should be connected, but they are not.

I have been in the mortgage world for decades, and this is one of the most common questions I receive. I’m not on the sales side and don’t follow rates closely, but as an underwriter, I see every loan and get a clear picture of current interest rates.

The funny part is, I can be at a party or out with friends, and it always comes up. As soon as people find out I’m in the industry, they want to know about interest rates. Once we finish that, they move on to underwriting or property questions. It feels a little like being a doctor at a party. There is no way to avoid it.


Mortgage Rates Have Their Own Rhythm

So here’s the answer I give. Mortgage interest rates move to a different rhythm. They are mostly tied to the bond market, especially long-term bonds like the 10-year U.S. Treasury bond and mortgage-backed securities (MBS). Think of it this way: while the Prime Rate might be playing classical music, mortgage rates are over in the corner dancing to their Swiftie playlist, singing ‘We Are Never Ever Getting Back Together’ with every market move.

A bond is basically a loan to the government or a company. Investors buy bonds because they are considered safer than stocks (or slot machines). A mortgage-backed security works in a similar way. It is a group of home loans bundled together and sold as an investment. Both are thought of as safer because they are backed by steady payments, either from the U.S. government or from thousands of homeowners making mortgage payments.


Why Investors Move Their Money

Now, why would investors ever move their money out of something safe? Because safer investments usually earn less money. If the stock market looks strong, investors may decide to take on more risk by putting money into stocks, where they could potentially make more profit. When that happens, fewer people buy bonds, bond yields go up, and mortgage rates rise.

On the other hand, if the stock market feels shaky, investors rush back into bonds and MBS to protect their money. More demand for these safe investments pushes yields down, and mortgage rates often fall.

A Real-Life Example: COVID Panic

Here’s a real-life example. In early 2020, when the COVID-19 pandemic hit, investors panicked over more than just the toilet paper shortage. The stock market dropped, and people withdrew their money from riskier investments. Much of that money was then invested in U.S. Treasuries and MBS. The surge in demand for safe investments pushed bond yields down, and mortgage rates quickly followed. It had nothing to do with the Prime Rate. It was all about investors seeking safety.


What the Prime Rate Actually Affects

So then, what does the Prime Rate actually influence? The Prime Rate is tied to short-term debt. It is the benchmark for things like credit cards, home equity lines of credit, short-term personal loans, and auto loans. Certain business loans also track the Prime Rate. That is why when the Fed cuts the Prime Rate, your credit card interest rate might go down, but your mortgage rate may not move at all.


Investor Confidence and Global Events

This all comes back to investor confidence. If investors feel confident about the economy, they take more risks. If something makes them nervous, they play it safe, like a groundhog seeing its shadow and ducking back into its hole. A strong jobs report, higher inflation, or global events like wars, oil shortages, or banking problems in another country can all shake that confidence. These shifts ripple into the bond market, and mortgage rates respond.


Mic Drop

So the next time someone asks you why mortgage rates didn’t follow the Fed, you can tell them the truth. Mortgage rates are not glued to the Prime Rate. They are shaped by investors, bonds, and the bigger picture of how the economy feels on any given day.

And me? I will keep answering the question at parties, smiling politely while I try to sneak back to the wine bar.
