Most homebuyers know mortgage rates go up and down — but few understand the forces behind those changes. This guide explains how mortgage rates are determined, the factors that affect mortgage rates, and why mortgage rates rise or fall. Understanding these drivers can help you secure a better rate, even in a changing 2026 housing market.

Economic Drivers That Move Mortgage Rates
Mortgage rates are not set at random — they are directly tied to broad economic forces. The biggest indicator is the yield on the 10-year U.S. Treasury bond, because mortgage-backed securities often track it.
1. Inflation
High inflation pushes interest rates higher because lenders need extra protection against purchasing-power loss. This is one major reason why mortgage rates rose sharply from 2021–2024.
2. Federal Reserve Policy
The Fed does not “set” mortgage rates, but it influences them through monetary policy. When the Fed raises short-term interest rates, borrowing becomes more expensive, which indirectly moves mortgage rates upward.
3. Economic Growth & Jobs Data
Strong employment reports, GDP growth, and consumer spending often push rates higher, while recession fears typically pull them downward.
4. Bond Market Demand
Investors buying mortgage-backed securities lowers yields (and mortgage rates). Weak demand does the opposite.

Lender Pricing: Why Rates Differ Between Banks
Even when economic factors set the overall direction, lenders adjust the final rate based on their own risk models and business goals.
1. Borrower Credit Score
Higher credit scores reduce risk, resulting in lower interest rates. A 760+ score can save thousands over a 30-year loan.
2. Loan Type
- Conventional mortgages
- FHA loans
- VA loans
- Jumbo loans
Each program has its own pricing, insurance rules, and rate tiers.
3. Down Payment Size
Larger down payments lower risk for lenders, which can reduce your rate.
4. Points & Credits
You can “buy down” the rate by paying points upfront, or accept a higher rate in exchange for closing credits.
5. Competition & Market Conditions
Some lenders temporarily lower rates to attract volume, especially in slow markets.
| Factor | Impact on Rate | Typical Effect |
|---|---|---|
| Credit Score | High scores lower rates | 0.25% – 1% difference |
| Loan Program | Risk-based pricing | Varies 0.50%+ |
| Points | Buy down or buy up | ~0.25% per point |
What Buyers Can Do to Get a Lower Rate
Even when market rates rise, buyers still have options to improve their pricing.
1. Raise Your Credit Score Before Applying
Even a 20–40 point increase can unlock better rate tiers.
2. Shop Multiple Lenders
Getting 3–5 quotes can save buyers thousands. Lenders price differently every day.
3. Consider Buying Discount Points
If you’re keeping the home for 5+ years, buying points may reduce long-term costs.
4. Choose a Shorter Loan Term
15-year and 20-year mortgages usually offer lower rates than 30-year loans.
5. Watch Market Timing (Mortgage Rate Prediction 2026)
Most analysts expect moderate rate declines in mid-2026 as inflation cools and the economy stabilizes — although nothing is guaranteed. Timing your rate lock may help you secure better pricing.
