Kevin Book states the "cold mathematics of inventory depletion" are at work, with OECD petroleum inventories inversely correlated to Brent price. He notes the SPR has limited room to draw further, and a prolonged Strait closure means inventory draws continue for "ten more days." If the conflict persists, the physical shortage of oil cannot be offset by inventories or increased production elsewhere. This fundamental supply constraint will keep upward pressure on prices.

The duration of the conflict and its direct impact on global inventories are the critical variables determining the magnitude of the price move. A swift, peaceful resolution and reopening of the Strait of Hormuz, allowing a rapid return of physical barrels to the market.
