Mortgage Rates Explained: What Moves Them & Why

Reviewed by Unpack Money Research Desk · Updated October 28, 2026 · Our review process

Quick answer

Mortgage rates are driven mainly by the bond market — yields on mortgage-backed securities, shaped by inflation expectations, Federal Reserve policy expectations, and economic data — not directly by the Fed's policy rate. Your individual rate then moves away from the average by credit, down payment, loan size, property, and lender. The only rate figures on this page are the single dated Freddie Mac snapshot below (October 22, 2026), which is a benchmark, not a quote. Rates change weekly — check the latest Freddie Mac release before acting on these figures.

The dated snapshot (do not read this as today's rate)

Freddie Mac Primary Mortgage Market Survey, October 22, 2026: these figures are a dated snapshot. Rates move weekly — check the latest PMMS release before using them, and do not carry the October 22 figures forward as current.

Read the scope before using these numbers: the PMMS covers conventional, conforming, fully amortizing home-purchase loans for borrowers who put 20% down and have excellent credit. Your rate will differ — by credit, down payment, loan size, property, and lender. These averages are a benchmark, not a quote.

What actually sets mortgage rates

1. The bond market, mainly. Lenders fund mortgages by selling them into mortgage-backed securities; yields on those securities — influenced by inflation expectations, Federal Reserve policy expectations, and economic data — are the largest driver of mortgage rates. The Fed's policy rate does not directly set mortgage rates.

2. Your borrower profile. Credit score and history, down payment and loan-to-value ratio, debt-to-income ratio, loan size (conforming vs. jumbo — the 2026 baseline conforming limit for one-unit properties is $832,750 per FHFA, with a $1,249,125 high-cost ceiling), property type, and occupancy all move your individual rate away from the average.

3. The loan itself. Term (30-year vs. 15-year), fixed vs. adjustable, and discount points (prepaid interest that lowers the rate) all change the rate — and the total cost — in different directions.

What a 1% difference costs

On a $400,000 loan over 30 years: at 7.32%, about $2,748 per month (principal and interest); at 6.32% (one point lower), about $2,481 per month — a difference of roughly $267 per month.

On a $300,000 loan over 30 years at 7.32%, principal and interest is about $2,061 per month; at 7.40% (the prior week's average) it is about $2,077 — about $16 more per month for that 0.08-point move. These figures exclude taxes, insurance, mortgage insurance, and fees, which are real parts of the monthly payment. Use the existing mortgage calculator for your own numbers, and a Loan Estimate from a lender for anything resembling a quote.

Rate vs. APR vs. points

Note rate: the interest rate on the loan itself; it drives the principal-and-interest payment.

APR: the note rate plus most lender fees and mortgage insurance, expressed as an annual rate. It is the better tool for comparing total loan cost across lenders — but only if the fee assumptions behind each APR are comparable.

Discount points: 1 point = 1% of the loan amount, paid upfront to reduce the rate. Points only pay off if you keep the loan long enough for the monthly saving to exceed the upfront cost. Ask every lender to quote with and without points, on the same loan, so the comparison is honest.

Locking, floating, and shopping

Get multiple Loan Estimates. Lenders must provide one within three business days of application. Compare APR, points, lender fees, and cash to close — not just the note rate.

Ask about a rate lock: what rate is locked, for how long, what it costs to extend, and what happens if the lock expires before closing.

Remember the payment is bigger than principal and interest. Taxes, homeowners insurance, and mortgage insurance (where applicable) are part of the monthly obligation; a rate comparison that ignores them understates the true cost.

What this means for you

Use the PMMS as a benchmark for direction, never as your rate. Your rate is set by the bond market plus your profile plus the loan structure — and the only number that resembles a quote is a Loan Estimate on your exact loan, on the same day as the others you compare.
