The average rate on a 30-year fixed mortgage climbed to 6.58% this week, its highest level of 2026 so far, according to Freddie Mac’s Primary Mortgage Market Survey released Thursday. It is the third straight weekly increase.
Freddie Mac’s survey, the industry’s benchmark weekly rate gauge, put the 30-year fixed average up from 6.55% a week earlier and 6.43% at the start of July. The 15-year fixed average rose to 5.96%, up from 5.93%. Despite the recent climb, both rates remain below where they stood a year ago: the 30-year averaged 6.74% in late July 2025, and the 15-year averaged 5.87%.
A steady climb since February
The 30-year rate has risen roughly 60 basis points since bottoming at 5.98% in late February, according to Freddie Mac data hosted by the Federal Reserve Bank of St. Louis. That puts current rates back near levels last seen in 2023, though still short of the 7%-plus rates that prevailed for stretches of 2023 and 2024.
Mortgage-industry trackers that publish daily, rather than weekly, rate averages have shown more volatility this week, with some reporting rates easing and others reporting new highs. Freddie Mac’s weekly survey, which samples rate locks from lenders nationwide, is the sourcing standard RealtyWire uses for market-wide mortgage rate figures.
What’s driving the increase
Mortgage-industry outlets, including The Mortgage Reports, have attributed this month’s rate increase to rising Treasury yields tied to renewed geopolitical tension in the Middle East and higher oil prices, which have stoked inflation concerns among bond investors. Mortgage rates track the 10-year Treasury yield closely because lenders price long-term home loans off that benchmark.
RealtyWire has not independently verified the specific magnitude of this week’s Treasury yield move; the rate driver described above reflects attributed industry reporting, not RealtyWire’s own analysis.
What it means
Verified facts: the 30-year fixed mortgage rate is at 6.58%, its highest weekly average so far in 2026, up for a third consecutive week, but still below its year-ago level.
Attributed interpretation: industry outlets tie the increase to rising Treasury yields amid inflation concerns linked to oil prices and geopolitical tension, rather than to any specific Federal Reserve policy action this week.
What to watch: Freddie Mac releases its next PMMS reading Thursday, July 30. Continued upward pressure would test the affordability gains many buyers saw earlier this year, following new home sales data released Friday showing softening prices even as financing costs rise.
