Key Takeaways
- • Freddie Mac's PMMS is the weekly benchmark for US mortgage rates, published Thursdays
- • It measures committed 30-year and 15-year fixed rates from thousands of lenders
- • Rates track the 10-year Treasury yield, not the Fed's short-term rate
- • Your personal rate also depends on credit, LTV, term, and points
- • Always check the live PMMS at freddiemac.com/pmms for the current figure
"What are mortgage rates doing?" is the question every buyer asks first. The most authoritative answer comes from Freddie Mac's Primary Mortgage Market Survey (PMMS), published every week. This guide explains what the PMMS measures, what actually moves rates, and how to read the report — including where to find the live 2026 number.
What the PMMS Actually Measures
The PMMS is a survey of the rates lenders are committing to borrowers on fixed-rate mortgages, based on application data from a large panel of lenders nationwide. It reports the average for the 30-year fixed and 15-year fixed, typically assuming the borrower pays about 0.5 discount points. Freddie Mac releases it weekly — historically every Thursday — through its Economic & Housing Research division.
It is a benchmark, not a quote. Your actual rate depends on your credit, down payment, loan size, property type, and the points you choose. But the PMMS tells you the national direction of travel.
What Drives Mortgage Rates
The single biggest driver is the yield on the 10-year US Treasury note. Mortgages are funded by investors who can instead buy government bonds, so lenders price home-loan rates as "10-year Treasury + a spread." When Treasury yields rise on inflation or Fed-policy expectations, mortgage rates usually follow. The Federal Reserve's short-term rate gets the headlines, but it is the 10-year yield and mortgage-backed-security (MBS) spreads that move your rate most directly.
- Inflation & Fed policy: Higher expected inflation pushes long-term yields (and mortgage rates) up.
- MBS spreads: The premium investors demand for mortgage risk widens or narrows with market stress.
- Your profile: Credit score, LTV, loan type (conventional/FHA/VA), and discount points shift your rate around the benchmark.
How to Read the Weekly Report
Each release shows the 30-year fixed, the 15-year fixed, and the associated points, plus the week-over-week change. Watch three things: (1) the level — how high or low the average is; (2) the trend — whether it is rising or falling week to week; and (3) the gap between the 30-year and 15-year rates, which signals how much you save by choosing a shorter term.
Because the figure is refreshed every Thursday, the most reliable way to know "what are rates today" in 2026 is to check the live survey directly: freddiemac.com/pmms. This guide intentionally cites the source for the current number rather than freezing a weekly average that would be stale the moment it publishes.
Putting the Rate Into Your Payment
A rate move of even 0.5% changes your monthly payment materially over a 30-year loan. Use the Mortgage Payment Calculator to plug in the current PMMS average (and a few what-if rates) and see the exact impact on your principal-and-interest payment. The Refinance Break-Even Calculator shows whether a rate drop justifies refinancing costs.
Editor Update Note
Reviewed August 4, 2026. The PMMS methodology and release cadence reflect Freddie Mac's published survey; mortgage-rate drivers (10-year Treasury, MBS spreads, credit, LTV, points) are standard market mechanics.

Frequently Asked Questions
What is Freddie Mac's PMMS?
The Primary Mortgage Market Survey (PMMS) is a weekly survey published by Freddie Mac's Economic & Housing Research division, typically every Thursday. It reports the average committed interest rates lenders are offering on 30-year and 15-year fixed-rate mortgages, based on applications submitted to thousands of lenders. It is the most widely cited benchmark for US mortgage rates.
Why does the PMMS matter?
Because it is a consistent, long-running, publicly available measure of where rates actually are. Reporters, lenders, economists, and policymakers reference it. It is not a rate quote for your specific loan, but it tells you the national trend and whether rates are rising or falling week to week.
What actually drives mortgage rates?
Mortgage rates track the yield on 10-year US Treasury notes more than the Fed's short-term rate, because most mortgages are funded by investors who compare them to government bonds. Inflation expectations, Federal Reserve policy, mortgage-backed-security (MBS) spreads, your credit score, loan-to-value ratio, loan type, and discount points all move your personal rate up or down from the benchmark.
Where do I find the current 2026 rate?
The exact current average is published each week in the PMMS at freddiemac.com/pmms (search "Freddie Mac PMMS"). Because the figure changes every Thursday, always check the live survey for the most recent 30-year and 15-year fixed averages rather than relying on a static number.
How can I get a rate below the average?
Improve your credit score, put 20% or more down to lower LTV, choose a shorter term (15-year beats 30-year), pay discount points to buy the rate down, and compare multiple lenders. Rate locks also matter — locking when the weekly PMMS dips can save you over the life of the loan.
