30-Year Fixed Rate Climbs to 6.73% Wednesday as Oil Prices Lift Borrowing Costs

Mortgage rates edged higher on Wednesday, September 9, 2026, according to [Yahoo Finance](https://finance.yahoo.com/personal-finance/mortgages/article/mortgage, refinance-rates-today-wednesday-september-9-2026-fixed-rates-inch-upward-51-arm-breaks-past-7-as-oil-prices-rise-100000700.html), with the average 30-year fixed rate climbing 6 basis points (one basis point equals one one-hundredth of a percentage point) to 6.73%, based on Zillow lender marketplace data.
The 5/1 adjustable-rate mortgage, or ARM, crossed 7% for the first time recently, settling at 7.03%, up 39 basis points from Tuesday.
The 15-year fixed loan moved only slightly, rising 1 basis point to 6.05%. Refinance rates tracked closely alongside purchase rates, with the 30-year fixed refinance averaging 6.75% on the same date.
What Is Driving Rates Higher
Rising oil prices are a central factor, with many market participants now anticipating the Federal Reserve will raise interest rates at its meeting next week, Yahoo Finance reported. That expectation is flowing through to mortgage pricing.
Broader inflationary pressures, including renewed conflict in Iran, have compounded the upward pressure on rates throughout recent weeks.
Fortune reported on September 7 that the 30-year conventional mortgage averaged 6.792%, up roughly 8 basis points from a week earlier, according to Mortgage Research Center data.
The 30-year jumbo loan stood at 6.830% on that date, and the 30-year FHA loan averaged 6.158%.
Rate Snapshot Across Loan Types
According to Zillow data cited by Yahoo Finance, Wednesday's full rate picture for home purchases included the 20-year fixed at 6.55%, the 7/1 ARM at 6.51%, the 30-year VA loan at 6.22%, and the 15-year VA at 5.78%. The 5/1 VA loan came in at 5.82%.
These figures are national averages, rounded to the nearest hundredth of a percentage point.
For refinancing borrowers, the 20-year fixed came in lower at 6.37%, and the 5/1 ARM refinance rate was 6.69%.
Housing Market Context
Fortune noted that purchase mortgage volume increased modestly during the recent period of rate volatility, even as refinance activity declined.
Mortgage Research Center data cited by Fortune described rates reaching their highest levels in four weeks as investor concern about inflation and rising deficits pushed yields higher globally.
In many local markets, buyers currently have a relatively wide selection of available homes, which Fortune reported is likely supporting transaction volume despite higher borrowing costs.
The rate environment has been unsettled since early September. A week earlier, on September 2, the 30-year fixed had briefly softened to 6.74% APR, according to Zillow data reported at that time, before resuming its upward climb.
Homebuyers locking a 30-year fixed rate at 6.73% today are borrowing at costs materially above the lows seen earlier this year.
The incremental daily moves remain modest in isolation, but the cumulative drift higher over several weeks is meaningful for monthly payment calculations on a typical purchase.
