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.

Frequently asked questions

- Rate locks protect you from market movement during a defined window and are worth considering once you're under contract or ready to move quickly.
