PBF Energy IncConflict in Strait of Hormuz widens crack spreads, boosting PBF's refining margins.

Shares of petroleum refiner PBF Energy rose 10.5% in the week to Friday morning, driven by widening crack spreads amid escalating conflict in the Strait of Hormuz. The 3-2-1 crack spread, a key profitability metric for refiners, climbed by double digits over the last week to close to $69, up from nearly $43 at the start of June and just $20 at the beginning of 2026. The increase followed the collapse of a memorandum of understanding with Iran, which has restricted commercial traffic through the Strait of Hormuz, a chokepoint for about a fifth of global crude oil flows and a major source of refined products. PBF benefits because it can secure domestic crude and profit from the wider spreads, and the longer the disruption persists, the more the company stands to gain.
