Why does my rate keep changing every day? Are they playing games?
Key Takeaways

- Rate locks protect you from fluctuations during your loan process
Why does my mortgage rate change every day?
You're seeing different mortgage rates each day because rates move constantly based on market conditions and economic factors. Lenders typically update their rates daily, sometimes multiple times per day, based on bond market activity, Federal Reserve actions, and economic news. This daily movement is normal market behavior, not manipulation.
Mortgage rates tie to the bond market, which trades continuously during business hours. When bond prices rise, rates fall—and when bond prices drop, rates increase. Economic reports, inflation data, and Fed announcements can cause rates to shift throughout the day. Lenders adjust their pricing to reflect these changes and manage their risk.
Your lender can explain how rate locks work to protect you from daily fluctuations. Most lenders offer rate locks for 30-60 days once you have a purchase contract or decide to move forward with a refinance. During the lock period, your rate stays the same regardless of market movement. Ask your lender about their rate lock policies and any fees involved. They can walk you through current rates and help you understand the timing that works best for your situation.
