Global oil refiners have experienced a significant surge in profits in recent weeks, driven by a rare convergence of strong fuel demand and lower crude oil prices following the reopening of the Strait of Hormuz. However, industry analysts warn that this boost in refining margins may be temporary as market dynamics continue to evolve.
The benchmark U.S. 3-2-1 crack spread—a key indicator of refining profitability measuring the difference between crude costs and refined fuel prices—recently exceeded $60 per barrel, marking an all-time high. Refining margins have also risen sharply across Asia and Europe. These elevated profits stem from two main factors: a decrease in crude oil prices and relatively strong prices for refined products such as gasoline, diesel, and jet fuel.
The shift in crude pricing follows the interim ceasefire agreement signed between the United States and Iran on June 17, which ended months of severe supply disruptions caused by the closure of the Strait of Hormuz. Supply constraints that had tightened crude markets abruptly reversed as hundreds of millions of barrels of oil, previously stranded in the Gulf, were released back into global circulation.
Data from Kpler shows total Middle East crude exports—including shipments from Saudi Arabia and the United Arab Emirates routed through ports bypassing the Strait—rose sharply to 12.35 million barrels per day (bpd) in June, up from less than 8 million bpd in May. Projections for July suggest exports will reach approximately 12.5 million bpd. Although these figures remain below the pre-conflict average of around 18 million bpd, the influx of supply has created a temporary glut in the market.
The increased crude availability is reflected in benchmark Brent crude futures, which have retreated to about $70 per barrel—near pre-conflict levels and approximately $50 lower than the peak prices seen during wartime conditions. Physical market conditions are even more bearish, with key Gulf producers such as Saudi Arabia and the UAE aggressively competing for market share by offering higher discounts on oil cargoes.
Industry observers note that this market environment may persist for several months, as producers are not only releasing stored crude from tankers and onshore storage but are also reactivating oilfields that were previously shut down during the conflict. Meanwhile, concerns remain about the sustainability of global demand growth, which could further pressure prices.
On the products side, refiners continue to capitalize on robust fuel consumption, bolstering their earnings. Despite the current favorable conditions, the combination of increasing crude supply and uncertainties over demand may limit refining profit margins in the near future.
