WTI, Brent Gain Amid Diesel Shock, Global Supply Concerns

Front-month WTI crude futures rose 0.94% to trade at $84.53 per barrel on Tuesday, August 18, while Brent crude gained 0.7% to $91.51, according to midday price data. The Bakken crude differential at the Clearbrook, Minnesota, hub widened to a discount of $3.42 per barrel versus WTI.

The gains in headline crude benchmarks occurred alongside a stark warning from veteran analyst Jeff Currie about a severe dislocation in global fuel markets. According to an interview published by OilPrice.com, Currie stated that while Brent near $91 looks "almost civilized," the real energy shock is in refined products. He noted European diesel was trading around $170 per barrel—almost double the price of Brent.

"Nobody on the planet earth consumes crude oil," Currie told CNBC. He argued that the historical relationship between crude and product prices has broken down, creating an "illusion of abundance." The disconnect stems partly from 100 million to 120 million barrels of crude being trapped inside the Strait of Hormuz since late June and China's subsequent cuts to refinery runs, which tightened product supplies further.

The inflation impact is direct: CNBC reported diesel prices are up 46% year-over-year, feeding into trucking, shipping, and industrial costs. Currie expects the dislocation to eventually correct as refiners chase high margins, but until then, crude prices may paint a misleading picture for consumers.

Global supply concerns provided additional support for crude. Rigzone reported that Rystad Energy says Russia's crude production has entered "a new era of constraint." Separate Rigzone reporting also highlighted ongoing market tension, questioning whether oil prices will keep rising as Iran tensions threaten global crude supply.

For Bakken operators, the wide differential presents a headwind to realizations, despite stronger absolute WTI prices. However, the extreme margins in the diesel market, a key refined product from crude, underscore the value of Bakken barrels to refiners able to process them. The sustained high product prices and constrained global supply narrative support a firm floor under the overall oil complex.

Natural gas prices also saw strength, rising $0.05 to $2.74 per MMBtu.
