Iran Conflict Drives Mortgage Rates Higher as Oil Prices Surge

The recent escalation of conflict in the Middle East, specifically the U.S.-Israeli strikes in Iran, is contributing to increased volatility in global energy markets and, upward pressure on U.S. Mortgage rates. After a three-week decline, the average 30-year fixed mortgage rate has ticked upwards, interrupting a period of relative stability for homebuyers.

Mortgage Rate Increase

According to data released by Freddie Mac on March 6, 2026, the average 30-year fixed-rate mortgage rose to 6.00% this week, up from 5.98% the previous week. While still below the 6.63% average recorded a year ago, this increase marks the end of a positive trend that saw rates fall to a three-and-a-half-year low in recent weeks. National Mortgage News reported on this shift, highlighting the sensitivity of mortgage rates to broader economic factors.

The Oil Price Connection

The primary driver behind this increase is a surge in oil prices, fueled by concerns over potential disruptions to oil supply in the event of a wider conflict. Goldman Sachs Research estimates that traders are demanding approximately $14 more per barrel of oil to compensate for increased risk. Iran produced around 3.5 million barrels per day (mb/d) of crude oil and 0.8 mb/d of condensate in 2025, representing approximately 4% of global oil supply. Disruptions to the flow of oil through the Strait of Hormuz, a critical waterway for global oil transport, are a major concern. Goldman Sachs estimates a full four-week halt in flows through the Strait of Hormuz could increase oil prices significantly, with even partial disruptions having a noticeable impact.

Impact on the Housing Market

Rising oil prices contribute to broader inflationary pressures, which in turn influence the Federal Reserve’s monetary policy. While the Federal Reserve doesn’t directly set mortgage rates, its decisions regarding interest rates have a significant impact on the 10-year Treasury yield, a benchmark lenders leverage to price home loans. As the 10-year Treasury yield climbed to 4.14% on Thursday, up from around 4% a week prior, mortgage rates followed suit.

This increase in mortgage rates comes at a time when the housing market is already facing challenges. Sales of previously occupied U.S. Homes remained at 30-year lows in 2025, and affordability remains a significant barrier for many potential homebuyers. While lower rates in recent months had begun to stimulate some demand, as evidenced by an 11% jump in mortgage applications the week of February 26, 2026, according to the Mortgage Bankers Association, rising rates threaten to dampen this momentum.

Looking Ahead

The trajectory of mortgage rates in the coming months will depend heavily on the evolution of the conflict in Iran and its impact on global oil prices. As Joel Berner, senior economist at Realtor.com, noted, “For rates to continue their descent in 2026, we will necessitate clear signals in the months to come that this conflict is not driving up prices for consumers at home.” A sustained increase in oil prices could lead to further rate hikes, potentially pushing homeownership further out of reach for many Americans. However, a wider selection of homes for sale and lower listing prices in some metro areas may offer some offset to the impact of higher rates.

Key Takeaways

• Mortgage rates have increased to 6.00% due to rising oil prices and geopolitical tensions.
• The conflict in Iran is the primary driver of oil price volatility.
• Rising rates pose a challenge to the housing market, which is already facing affordability issues.
• The future direction of mortgage rates will depend on the resolution of the conflict and its impact on inflation.
