The 5/1 adjustable rate mortgage climbed to 7.03 percent, up 39 basis points from Tuesday. Rising oil prices are driving expectations for a Federal Reserve rate hike.

The 5/1 adjustable rate mortgage climbed to 7.03 percent on Wednesday, September 9, 2026. This represents an increase of 39 basis points from Tuesday. The 30-year fixed rate rose 6 basis points to 6.73 percent. The 15-year fixed rate edged up 1 basis point to 6.05 percent.

These figures are national averages from the Zillow lender marketplace. Market participants expect the Federal Reserve to raise interest rates next week. This outlook follows a recent surge in oil prices. The energy sector inflation pressure is altering the monetary policy trajectory.

Refinance spreads widen across terms

Refinance rates generally remain higher than purchase rates. The 30-year fixed refinance rate stands at 6.75 percent. The 15-year fixed refinance rate is 6.11 percent. The 5/1 ARM refinance rate is 6.69 percent.

The 20-year fixed refinance rate is 6.37 percent. VA loan refinance rates show similar patterns. The 30-year VA refinance rate is 6.17 percent. The 15-year VA refinance rate is 5.71 percent.

Fixed term trade-offs persist

Borrowers choosing 30-year fixed loans accept higher total interest costs. Monthly payments are lower due to the extended amortization period. The rate remains constant for the life of the loan. This provides payment predictability against future economic shifts.

Fifteen-year fixed loans carry lower interest rates than thirty-year terms. Monthly payments are higher because the principal is repaid faster. Total interest paid over the life of the loan is significantly lower. Borrowers must qualify for higher debt-to-income ratios.

Oil prices impact mortgage outlook

Rising oil prices are a primary driver for today's rate increases. Higher energy costs feed into broader inflation metrics. The Federal Reserve is expected to respond with higher policy rates. This environment favors fixed-rate debt over adjustable structures.

GN auto markets and bonds desk data confirms the trend. Bond yields have moved in tandem with the oil price spike. Mortgage lenders adjust their pricing models to reflect this risk. Borrowers should monitor weekly rate changes closely.
