Direct answer

Market mortgage rates are driven primarily by the bond market — particularly mortgage-backed securities — and are influenced by economic data, inflation expectations, and monetary policy. Your personal rate then reflects credit, loan-to-value, program, property type, and occupancy.

Key takeaways

  • The Federal Reserve does not set mortgage rates directly.
  • Mortgage-backed security prices move rates day to day.
  • Discount points can buy down your personal rate.

Market rate vs. your rate

The rate you're quoted is the market rate adjusted for your specific loan characteristics.

Important limitations

  • Mortgage guidelines, eligibility, loan limits, rates, fees, and program availability may change and can vary by lender, investor, property, occupancy, state, and borrower profile.
  • This article is educational and does not constitute a commitment to lend, a rate quote, or personalized financial advice.
