Global Oil Inventories Crash as Strait of Hormuz Closure Deepens Supply Shock

Global crude and fuel inventories are plummeting at a record pace as the supply disruption from the Middle East war overwhelms the market's ability to cope without drawing down stocks, according to an analysis from OilPrice.com. While futures markets speculate on a potential U.S.-Iran deal to reopen the Strait of Hormuz, the physical disruption has already erased the oversupply present at the start of the conflict and is rapidly depleting commercial stockpiles.

Analysts warn the situation will worsen before it improves. "Inventory support remains finite and cannot sustainably offset prolonged disruptions," Sumit Ritolia at Kpler wrote last week. Goldman Sachs estimates global oil inventories are approaching an eight-year low, with the speed of depletion exposing the market to further shocks. Total global oil stocks have dropped to about 101 days of expected demand and could fall to 98 days by the end of May if the Strait remains closed.

For Bakken operators, this intensifying global supply crunch provides a powerful price floor and reinforces the value of secure, non-OPEC production. The rapid inventory drawdowns signal a tight physical market that typically supports stronger price differentials for inland crudes like Bakken. Even if the Strait of Hormuz reopens soon, analysts note it would take months for flows to normalize and for stock draws to reverse, suggesting sustained market tightness through the peak summer demand season.

Refined product stocks are falling even faster than crude, with fuel buffers "approaching very low levels fast," according to Goldman Sachs. Jet fuel stocks in the key Amsterdam-Rotterdam-Antwerp hub, for example, fell to their lowest level since March 2020 in late April. This global fuel tightness could increase demand for U.S. refined product exports, indirectly supporting domestic refining demand for Bakken crude.

The supply shock is already reshaping global revenue flows. According to Rigzone, Russia's oil tax revenue surged to a six-month high in April, directly benefiting from the crude price rally driven by the Iran war. This underscores how geopolitical disruptions create winners and losers in the oil market, with non-OPEC+ producers like those in the Bakken positioned to benefit from elevated prices.

The market has moved swiftly from a projected surplus. Patrick Pouyanné, chief executive of TotalEnergies, noted the 2026 surplus scenario was "quickly erased by the war," with global hydrocarbon inventories being drawn to balance the market at a pace of 10 to 13 million barrels per day. This abrupt shift from surplus to deficit highlights the fragile state of global supply and the critical role of stable production basins like the Bakken in a volatile geopolitical landscape.
