Borrower-facing mortgage averages moved higher on Wednesday in Zillow’s lender marketplace data. The 5/1 adjustable-rate mortgage averaged 7.03%, up 39 basis points from Tuesday, while the 30-year fixed averaged 6.73%, up 6 basis points, and the 15-year fixed averaged 6.05%. Yahoo Finance, citing Zillow, framed rising oil as lifting expectations that the Fed could tighten next week. That is expectation language only. The September FOMC has not decided, and that does not mean the Fed has already hiked.
Methodology matters. The ARM-above-7% claim is a Zillow marketplace average, not a universal national rate. Mortgage News Daily showed a 30-year fixed index near 6.89% as of Sep. 8. MBA’s weekly survey for the week ended Sep. 4 put the 30-year near 6.85%.
Tuesday’s Zillow set had the 5/1 ARM at 6.64%, underscoring volatile ARM swings. This is a household rates story: product, source, and oil as a backdrop for rate-path expectations, not a completed policy move.
