US Mortgage Rates Hit Highest Level Since August

CNBC reported Wednesday that US mortgage rates rose last week to their steepest level since August 2025, dealing a fresh blow to both refinancing activity and prospective homebuyers. Total mortgage application volume slid 8.5% week over week, according to data from the Mortgage Bankers Association.

Rates Cross a Key Threshold

The average 30-year fixed rate on conforming loan balances, those at or below $832,750, moved from 6.56% to 6.65%. Borrower points climbed alongside it, rising to 0.65 from 0.60 on loans carrying a 20% down payment. The rate has now advanced 30 basis points over five consecutive weeks, erasing the more favorable conditions that had briefly attracted rate-sensitive borrowers back to the market.

Refinance Activity Takes the Hardest Hit

Refinancing applications bore the brunt of the rate move, dropping 18% in a single week. Joel Kan, vice president and deputy chief economist at the MBA, told CNBC that declines were broad-based across loan types. Conventional refinances fell 14%, FHA applications dropped 18%, and VA applications tumbled 34%. Refinance requests shrank to just 38% of total application volume, their lowest share since June 2025. Despite the weekly collapse, refi activity still ran 19% above year-ago levels. That comparison reflects a stark reality from 2025, when the 30-year rate sat roughly 33 basis points higher than today.

A Cooling Backdrop for Housing

Purchase applications fell a more modest 0.4% for the week. Year-over-year gains narrowed to just 5%, a sign that the brief momentum building earlier in spring may be fading. One notable data point underscored affordability pressure. The average loan size on a purchase application reached a new survey record of $473,600. Kan noted that borrowers with smaller loan balances were the least active, squeezed hardest by higher rates and reduced purchasing power.

Early Signs of Relief This Week

Not all signals pointed in the same direction. A separate Mortgage News Daily survey showed rates edged marginally lower at the start of this week. Easing geopolitical tension around the Iran conflict lifted bond markets, pulling Treasury yields lower and dragging mortgage rates down with them. Whether that relief proves durable will depend on how bond investors read incoming economic data and any further developments on the geopolitical front.
