US refiner profit margins hit record as Iran war disrupts supply routes

US refiners are experiencing record profit margins from gasoline and diesel production due to elevated prices driven by supply disruptions linked to geopolitical tensions. As of July 16, 2026, refiner margins reached $69.66 per barrel, propelled by the 3-2-1 crack spread, which rose over 2% amid ongoing Middle East conflicts. The situation has been exacerbated by the Iran war, impacting critical supply routes such as the Strait of Hormuz. This has led to significant price hikes in U.S. gasoline, now averaging $4.54 per gallon, marking a 52% increase compared to pre-conflict levels.

Markets appear to be responding to these developments with increased speculation on the potential for crude oil prices to reach a new all-time high. The surge in refiner profit margins is seen as a catalyst that could influence crude oil pricing, with the current market pricing a 5% probability for a new high by September 30, and a 12.5% probability by December 31.

The pricing of these predictions suggests that markets are factoring in the potential for continued supply disruptions and geopolitical tensions. Key figures such as Mohammad Sanusi Barkindo of OPEC and Abdulaziz bin Salman Al Saud, Saudi Minister of Energy, remain central to any forthcoming developments that could impact oil supply dynamics.

Key Takeaways

• The record profit margins for US refiners appear to be driven by rising crack spreads and geopolitical tensions.
• Market pricing suggests a cautious outlook on crude oil reaching a new all-time high by the end of the year.
• Current geopolitical instability may continue influencing market expectations and crude oil pricing.

What to Watch

The situation in the Middle East, particularly the Iran conflict, remains a key factor. Any resolution or escalation could significantly impact crude oil supply and pricing. Market observers will be closely monitoring statements from OPEC and other major oil-producing nations. Additionally, fluctuations in the crack spread and changes in U.S. fuel stockpile levels could provide further insights into market directions. The potential for new developments in the geopolitical landscape may indicate shifts in market pricing towards either YES or NO outcomes in crude oil reaching a new all-time high.
