Mortgage Rates Dip to 6.67% Amid Iran Peace Deal Hopes

Average rates for 30-year fixed home loans decreased to 6.67% for the week concluding August 13, marking a 2 basis point reduction from the previous week's 6.69%, according to Freddie Mac. This slight dip occurred as market participants awaited developments regarding a potential resolution to the conflict involving Iran and the subsequent normalization of global oil prices. Despite this minor decrease, mortgage rates remain elevated compared to the same period in the prior year, having surpassed the year-ago threshold for the first time in 2026 during the preceding week. For comparative context, the average rate stood at 6.58% during the corresponding week in 2025. Sam Khater, Freddie Mac's Chief Economist, commented on the stability of mortgage rates at 6.67% this week, noting that improved housing affordability from a year ago, coupled with recent upticks in purchase and refinance applications, indicates that borrowers are responsive to even marginal shifts in mortgage rates. Mortgage rates have demonstrated a close correlation with oil prices in recent months, driven by concerns that escalating energy costs could precipitate persistent inflation. Last week, speculative reports of a peace agreement that would facilitate the reopening of the crucial Strait of Hormuz led to a temporary decline in crude oil prices, with mortgage rates briefly mirroring this trend. However, this period of relief proved to be transient. Hopes for a diplomatic resolution faltered as Iran presented demands, including "service fees" for passage through the strait, the complete cessation of a U.S. blockade on Iranian ports, the lifting of sanctions, and the provision of war reparations. President Donald Trump asserted on Wednesday that the U.S. exercises "total control" over the Strait of Hormuz, a claim that Iran has contested. Concurrently, maritime traffic through this vital chokepoint experienced a reduction to a weekly low of just eight vessels, as reported by Reuters. Joel Berner, Senior Economist at Realtor.com, observed that the 10-year Treasury yield has seen only a modest increase this week, despite the prolonged conflict in Iran, which continues to exert pressure on oil prices and, consequently, on projections for future inflation. The 10-year Treasury yield, a significant benchmark for mortgage rates, had previously declined last week amidst rumors of a peace deal, but has since trended upward as negotiation efforts have stalled. The Federal Reserve's monetary policy, particularly its stance on interest rates, remains a key factor influencing mortgage rates, alongside broader economic indicators and geopolitical events.
