How Mortgage Rates Are Set: Key Influencing Factors

Understanding the Factors That Influence What You Pay

If you’re planning to buy a home or refinance your mortgage, you’ve probably noticed that mortgage rates fluctuate, and often. But how are these rates actually determined? Let’s break down what goes into the calculation of mortgage rates and the major factors that can impact what you pay.

1. The Federal Reserve and the Economy

Mortgage rates are heavily influenced by the broader economy, especially the decisions made by the U.S. Federal Reserve. While the Fed doesn’t set mortgage rates directly, it adjusts the federal funds rate, which in turn affects the cost of borrowing across the financial system.

When the Fed raises rates to combat inflation, mortgage rates tend to rise as well. Conversely, when the Fed lowers rates to stimulate borrowing, mortgage rates usually drop.

2. Bond Market Activity

Mortgage lenders often look to the yields on 10-year U.S. Treasury bonds to guide their rates. When bond yields rise, mortgage rates generally follow. Investors flock to or flee from bonds depending on economic forecasts, which adds a layer of volatility.

3. Inflation

Inflation eats away at the purchasing power of money. When inflation is high, lenders demand higher interest rates to ensure they’re compensated for the loss in future value. If inflation cools, lenders may offer lower rates.

4. Your Credit Score

A borrower’s credit score is a personal financial factor that significantly impacts the mortgage rate offered. Higher credit scores often unlock lower rates, as they indicate a lower risk of default. Lenders reward creditworthiness with better terms.

5. Loan Type and Term

The structure of your mortgage also matters:

• Fixed-rate vs. adjustable-rate mortgages (ARMs): ARMs usually start with lower rates, but can change over time.
• Loan term: A 15-year mortgage often has a lower rate than a 30-year mortgage, though monthly payments are higher.

6. Down Payment Amount

Putting down a larger percentage of the home price reduces the lender’s risk, often resulting in a better rate. A down payment of 20% or more can also help avoid private mortgage insurance (PMI), further reducing costs.

7. Lender Competition and Location

Rates can vary between lenders due to competition and regional market conditions. Shopping around can help you find the best deal.
