Mortgage Rates Halt Their Recent Surge, Falling for Almost Every Loan Type

Just over a week ago, mortgage rates took a large jump higher as the bond market reacted to the possibility that President Trump’s proposed tax bill could become law. Experts say passing the bill could inflate the federal deficit since it would extend substantial tax cuts and boost government spending for years. That mere prospect shot 10-year Treasury yields higher—and in turn, caused a mortgage rate surge.

But in the five market days since, mortgage rates have retreated every day but one, dropping the major new purchase averages back to 3-week and 4-week lows.

Below, you can see the change in rates over the past week for each new purchase loan average. We then dive deeper into 30-year, 15-year, and jumbo 30-year fixed-rate loans.

30-Year Mortgage Rates Have Erased the Trump Tax Bill Bump—And Then Some

After shooting up to 7.12% to end the week on May 23, rates on 30-year new purchase loans saw their rate momentum shift last week. Retreating 13 points, the flagship average is back down to 6.99%—its cheapest level in three weeks.

However, things were much better in September, when the 30-year average plunged to a two-year low of 5.89% (the cheapest Friday average being 6.03%). So far this year, the lowest weekly reading has been 6.55%.

15-Year Mortgage Rates Drop Back Near 6%

Rates on 15-year new purchase loans fell a milder 9 basis points last week, dropping to an average of 6.01% on Friday. That’s a full 30 basis points below the 2025 high of 6.31%. But it’s also more than a percentage point above the two-year low of 4.97% registered in September (with a 5.07% low among Friday weekly averages).

Jumbo 30-Year Rates Sink Under 7% Again

Rates on jumbo 30-year new purchase loans fell a bold 14 basis points last week, pushing the average back below the 7% threshold. Friday’s reading of 6.96% is an improvement vs. the 2025 high of 7.15%. In contrast, September rates on new 30-year jumbo loans sank as far as 6.24%, with the lowest weekly average registering at 6.39%.

What’s a jumbo loan?

A jumbo mortgage is one that exceeds the maximum loan limits for Fannie Mae and Freddie Mac conforming loans—$806,500 for single-family homes in most parts of the U.S. in 2025, but up to $1,209,750 in certain more expensive areas.
