WTI Crude Squeezed by Hormuz Threat and Diesel Export Ban Speculation

The price of WTI crude oil is being squeezed between two opposing forces: the threat to global supply through the Strait of Hormuz and speculation about a US diesel export ban. The recent widening of the spread between Brent and WTI futures contracts for November delivery reflects this push and pull, with Brent's premium over WTI now at $13 a barrel.

The underlying drivers of this divergence are different from those in March, when both contracts surged due to concerns about supply disruptions. This time, Brent is rising while WTI is falling, with the latter down around $7 since September 18.

The narrative behind the diesel export ban speculation suggests that if US refiners are restricted from exporting diesel, they will have less incentive to process crude oil, resulting in weaker refinery demand for WTI relative to Brent. The record high US diesel prices, up 42.6% since July 10, add to the pressure on President Trump and Republican lawmakers.

Trump's upcoming announcement at 2:00pm ET is a key event risk that could determine whether the recent pressure on WTI extends or starts to unwind. In the short term, technical signals are uncertain, but WTI has shown respect for known levels around $93.60, which has repeatedly acted as resistance and support.
