One of the most common client misconceptions in mortgage: the Fed cuts rates so mortgage rates should drop immediately. The Federal Reserve controls the overnight Fed funds rate, which governs interbank lending. The 30-year fixed mortgage rate is set by the bond market, primarily the 10-year Treasury yield. They are different instruments with different drivers.
What the Fed Funds Rate Actually Controls
- ✦The Fed funds rate is the rate at which banks lend overnight reserves to each other
- ✦The Fed directly controls this rate through its monetary policy decisions at FOMC meetings
- ✦This rate directly affects short-term products: credit card rates, auto loans, home equity lines of credit (which are tied to Prime), and adjustable-rate mortgages with short initial fixed periods
- ✦When the Fed raises or cuts the funds rate, HELOC rates move almost immediately because they are indexed to Prime, which is set at Fed funds plus 3%
What Drives the 30-Year Fixed Mortgage Rate
The 30-year fixed mortgage rate tracks the 10-year Treasury yield with a spread that reflects mortgage-specific risk. The 10-year Treasury yield is set by supply and demand in the bond market, driven by inflation expectations, economic growth forecasts, and investor risk appetite. If inflation expectations rise after a Fed cut, the 10-year yield can increase even as the Fed funds rate falls. Mortgage rates can move in the opposite direction from the Fed's action in this scenario.
Historical Disconnects
- ✦Fed cuts in a high-inflation environment: if the market believes cuts are premature, long rates rise on inflation fear, pushing mortgage rates up
- ✦Fed holds rates steady while inflation decelerates: 10-year yields can fall ahead of any Fed action, pulling mortgage rates lower before the first cut
- ✦Fed raises rates aggressively: short-term products like HELOCs rise immediately; fixed mortgage rates may have already priced in the hikes
- ✦The bond market is forward-looking: mortgage rates reflect expectations of the next 12 to 24 months of economic conditions, not the current Fed stance
How to Use This With Clients
- ✦When a client is waiting for Fed cuts to buy a house, explain that mortgage rates may have already moved before the first cut
- ✦Rate lock decisions should be based on bond market signals (10-year Treasury direction, inflation data) rather than waiting for FOMC announcements
- ✦ARM products are more directly tied to short-term rates than fixed products: explain the difference when comparing 7/1 ARM vs. 30-year fixed scenarios
