Mortgage rates moved higher again on May 26, 2026, with the average 30-year fixed rate at 6.46%, according to the Zillow lender marketplace. That was 12 basis points above yesterday’s level and marked another move higher above 6% APR in the weekly survey of mortgage lenders with the best rates.
The 15-year fixed loan was 5.91%, up 1 basis point from the day before, while the 5/1 ARM stood at 6.68%, 39 basis points higher than Monday. For borrowers tracking mortgage news daily, the latest numbers point to a market that keeps drifting up rather than settling into a narrow range.
The move matters because the benchmark 30-year loan is the product most buyers watch first, and a 12-basis-point jump in a single day can change monthly payment calculations on the margin. A borrower shopping a home purchase or a refinance sees those changes immediately in quoted rates, even if the broader housing picture has not shifted.
The Zillow lender marketplace is one of the standard snapshots used to show where mortgage pricing stands from day to day. The source also notes that mortgage refinance rates are usually higher than purchase rates, which is part of why homeowners comparing options can see a different quote from buyers entering the market. Fixed-rate mortgages lock the rate from day one, while adjustable-rate mortgages can change after an initial fixed period.
That makes the spread between the 30-year fixed, the 15-year fixed and the 5/1 ARM worth watching. The 15-year loan remains lower than the 30-year option, but the sharp weekly rise in the ARM shows how quickly pricing can shift when lenders reprice risk. For now, the market’s message is simple: borrowing costs are moving up, and they are doing it fast enough to matter to anyone planning a purchase or refinance this week.
