Geopolitical tensions push US 30-year mortgage rate to 6.48%
Escalating tensions with Iran pushed US mortgage rates higher last week, keeping the 30-year fixed rate at 6.48% and signalling that borrowers should not expect relief this year.
US mortgage rates climbed over the past week as an escalating conflict involving Iran pushed borrowing costs higher. According to Zillow lender marketplace data released on Sunday, the benchmark 30-year fixed rate rose 4 basis points to 6.48%. The 15-year fixed rate saw a steeper increase, gaining 8 basis points to reach 5.90%.
These weekly gains underscore how quickly geopolitical instability can disrupt mortgage pricing. For the housing market, the shift keeps financing costs elevated, squeezing affordability for new purchases and limiting the incentive for existing homeowners to refinance.
Institutional forecasters do not expect this elevated baseline to shift anytime soon. The Mortgage Bankers Association currently projects the 30-year fixed rate will remain tightly bound between 6.4% and 6.5% for the remainder of 2026. Fannie Mae’s outlook aligns closely, pegging the year-end rate at 6.4%. Such forecasts suggest the market has priced in a prolonged period of elevated rates.
The current environment is also producing unusual distortions in mortgage product pricing. Adjustable-rate mortgages, which typically offer a discount to fixed-rate products during the initial lock period, are now trading near parity with long-term rates. The 5/1 ARM stands at just 6.46%, a mere two basis points cheaper than the 30-year fixed. The 7/1 ARM is priced at 6.35%, sitting above the 20-year fixed rate of 6.18%.
This pricing dynamic removes the traditional incentive for borrowers to choose adjustable-rate products, effectively making fixed-rate loans the default choice for cost-conscious buyers.
Government-backed Veterans Affairs loans continue to offer the most favorable terms in the broader market. The 15-year VA loan sits at 5.47%, while the 30-year VA rate is at 5.93%. In the refinancing segment, rates are largely mirroring primary market levels, with the 30-year fixed refinance at 6.48%. The notable exception is the 5/1 ARM refinance, which sits lower at 6.28%.
While daily figures showed a 29 basis point drop in the 5/1 ARM from the prior day, the weekly trend confirms the upward pressure stemming from the Iranian conflict. For market participants, the data reinforces that waiting for a significant rate drop is an ineffective strategy. Borrowers are instead advised to focus on optimizing credit profiles and lowering debt-to-income ratios to secure better pricing within the current 6.4% to 6.5% band.
