What Causes Mortgage Rates to Go Up or Down?
When you’re buying a home or refinancing, mortgage rates play a huge role in your monthly payment and overall affordability. But what actually makes these rates move? While many factors influence the market, two of the biggest drivers are the Federal Reserve’s federal funds rate and the 10-year U.S. Treasury yield.
The Federal Funds Rate
The Federal Reserve (the Fed) doesn’t directly set mortgage rates, but it does control the federal funds rate—the short-term interest rate that banks charge each other for overnight lending.
When the Fed raises the funds rate, borrowing costs increase across the economy. This often pushes mortgage rates higher, as lenders pass on the increased cost of money to borrowers. Conversely, when the Fed lowers the funds rate, mortgage rates tend to move down, though not always immediately or by the same amount.
The 10-Year Treasury Yield
Mortgage rates are more closely tied to the 10-year Treasury yield than to the Fed funds rate. Investors view U.S. Treasury bonds as a safe investment, and the yield reflects what investors demand in return for lending their money to the government.
Since most people keep their mortgages for about 7–10 years before selling or refinancing, lenders use the 10-year Treasury yield as a benchmark. When Treasury yields rise, mortgage rates usually rise as well, and when they fall, mortgage rates tend to follow.
Other Factors at Play
- Inflation: Higher inflation erodes the purchasing power of future interest payments, which leads lenders to charge higher rates.
- Economic Growth: A strong economy typically leads to higher rates as demand for credit increases.
- Global Events: Uncertainty in global markets often pushes investors toward U.S. Treasuries, driving down yields and, in turn, mortgage rates.
