Every time the Federal Reserve cuts interest rates, I get calls from buyers who expect mortgage rates to drop the same day. Sometimes rates do drop. Sometimes they go up. Occasionally they do not move at all. The confusion comes from a misunderstanding of which rate does what.
Two Different Rates
The Federal Reserve controls the federal funds rate, which is the overnight rate that banks charge each other for short-term loans. This rate directly influences: savings account yields, money market rates, credit card interest rates, home equity lines of credit (HELOCs), and auto loan rates.
Mortgage rates are different. Long-term fixed mortgage rates are primarily determined by the bond market, specifically the yield on the 10-year U.S. Treasury Note and the market for mortgage-backed securities (MBS). The Fed does not directly set these rates.
The Actual Mechanism
When the Fed cuts rates, it signals that monetary policy is loosening. This can cause bond investors to demand lower yields on Treasuries, which would reduce mortgage rates. But that is a second-order effect, not a direct link.
Mortgage rates move based on: bond market expectations about future inflation, the supply and demand for mortgage-backed securities, economic data releases (jobs reports, CPI, GDP), and geopolitical events that cause investors to move toward or away from bonds.
The Fed's rate cut announcement is one of many factors that influence these market forces. Sometimes it is the dominant factor and rates drop significantly. Sometimes the market had already priced in the cut and rates barely move. Sometimes other economic data released the same week overwhelms the Fed's signal and rates move the opposite direction.
Why This Matters for Buyers
Buyers who are timing their purchase around Fed meetings are making a mistake. They are watching the wrong indicator. A more useful practice is watching the 10-year Treasury yield, which has a direct and near-real-time relationship with mortgage rate movement. When the 10-year yield falls, mortgage rates tend to follow within days. When it rises, mortgage rates follow.
The Fed meeting may move the 10-year yield. Or it may not. The relationship is real but indirect.
The Inflation Connection
The most important factor in mortgage rates over the past three years has not been the Fed funds rate directly. It has been inflation. Inflation erodes the real return on fixed-income investments like bonds. When inflation is high, bond investors demand higher yields to compensate. Higher Treasury yields produce higher mortgage rates.
The Fed's primary tool for fighting inflation is raising the federal funds rate, which slows economic activity and reduces price pressure. As inflation fell from its 2022 peak, mortgage rates began to moderate even before the Fed cut its benchmark rate, because bond markets anticipated the easing cycle and priced it in advance.
What You Should Watch Instead
For buyers trying to understand where rates are heading: watch inflation data (CPI and PCE reports), watch jobs reports (stronger employment = higher rates, weaker employment = lower rates), and watch the 10-year Treasury yield directly. These are the actual inputs to your mortgage rate. The Fed meeting is a signal, not the source.
