The average rate on a 30-year fixed mortgage eased to 6.65% for the week ending Aug. 20, 2026, its second straight weekly decline, Freddie Mac’s Primary Mortgage Market Survey showed Thursday. The move gives prospective buyers a small measure of relief heading into the final weeks of summer, even as borrowing costs remain higher than a year ago.
The 30-year fixed rate slipped from 6.67% the prior week. A year ago it averaged 6.58%, leaving today’s rate nine basis points above its year-earlier level. The 15-year fixed-rate mortgage averaged 5.95%, down from 5.96% a week earlier and up from 5.69% a year ago.
“With a dip in rates providing modest relief for homebuyers, it’s important to remember borrowers can potentially save thousands by shopping around for the best mortgage rate,” Freddie Mac said in its release.
Rates edge back from 2026 highs
The two-week pullback follows a stretch that pushed the 30-year fixed to its highest levels of the year. Rates had climbed for several consecutive weeks earlier in the summer before topping out, and the survey has since drifted lower by two basis points in each of the past two weeks, following last week’s dip to 6.67%. The 30-year rate remains within a narrow band that has held for most of 2026, trading between roughly 6.5% and 6.9%.
Freddie Mac’s survey measures rates on conventional, conforming mortgages for borrowers who make a 20% down payment and have strong credit. Borrowers with smaller down payments or lower credit scores typically pay more, and the rate a given buyer is quoted can vary meaningfully from lender to lender.
Mortgage rates track the yield on the 10-year Treasury note more closely than they track the Federal Reserve’s benchmark short-term rate. The recent easing in survey rates has come as longer-dated Treasury yields fluctuated, with bond markets weighing the path of inflation and the Fed’s next moves. Minutes from the Federal Open Market Committee’s July meeting, released this week, showed several policymakers flagging inflation risks and the possibility that rates may need to move higher rather than lower.
Affordability pressure persists
Even with the modest decline, financing costs continue to squeeze affordability. At 6.65%, the monthly principal-and-interest payment on a $400,000 loan is roughly $2,570, hundreds of dollars a month higher than it would have been when rates sat near 3% earlier this decade. The National Association of Home Builders reported this week that housing affordability worsened as higher mortgage rates offset other factors, and homebuilder confidence has stayed near multi-year lows.
Higher rates have also kept many existing homeowners in place. A large share of outstanding mortgages carry rates well below current levels, discouraging owners from selling and trading into a costlier loan β a dynamic that has kept for-sale inventory constrained across much of the country. Purchase-mortgage demand has softened accordingly, with applications running below year-ago levels.
The direction of rates from here depends heavily on incoming inflation and labor-market data and on how bond markets read the Fed’s intentions. A sustained move lower would improve buyer purchasing power at the margin, while renewed inflation concerns could reverse the recent easing.
What it means: A two-basis-point weekly decline does little on its own to change the math for most buyers, and rates remain elevated relative to a year ago. But the shift lower, however small, marks a pause in the upward pressure that defined much of the summer. Whether it becomes a trend will hinge on the data the Fed and bond markets are watching in the weeks ahead.
Freddie Mac has published the Primary Mortgage Market Survey since 1971. The figures reflect rates offered to borrowers and do not include the fees and points many lenders charge, which add to the effective cost of a loan.
