Global oil inventories are nearing critical lows as the ongoing closure of the Strait of Hormuz has removed approximately 13 million barrels per day (bpd) from the market, according to data from the International Energy Agency (IEA). While futures traders have largely bet on a swift diplomatic resolution, industry leaders at Exxon and Chevron warn that the physical depletion of strategic and commercial stocks is setting the stage for a potential price spike to $160 per barrel.
Why are global oil stocks dropping to record lows?
The primary driver of the current inventory drain is the sustained, multi-month blockage of the Strait of Hormuz, a vital maritime chokepoint. According to the IEA, global oil supply dropped by 1.8 million bpd in April alone, contributing to a total loss of 12.8 million bpd since February. As a result, nations have been aggressively tapping into strategic reserves to compensate for the missing supply. The IEA reports that observed global inventories, including oil currently in transit, plummeted by 250 million barrels during March and April—an average draw of 4 million bpd.
The United States is currently holding its lowest level of weekly crude and petroleum product stocks since 2004. As of late May, U.S. inventories stood at 1.53 billion barrels, according to Energy Information Administration (EIA) data.
What happens if the Strait of Hormuz remains closed?
Industry executives warn that the market is rapidly approaching a “tipping point” where existing buffers will no longer be able to suppress price volatility. Neil Chapman, Senior Vice President at Exxon, noted at the Bernstein 42nd Annual Strategic Decisions Conference that current inventory levels are “unheard of.” Chapman stated that financial models suggest dated Brent crude could climb to between $150 and $160 per barrel once inventories reach the projected rock-bottom levels.

Chevron CEO Mike Wirth reinforced this outlook, explaining that the market’s “shock absorbers” are being steadily exhausted. Wirth warned that as these buffers disappear, the imbalance between supply and demand will flow directly into physical prices, likely increasing upward pressure throughout June and July.
How does the futures market compare to physical reality?
There is a stark disconnect between the sentiment-driven futures market and the physical reality of storage tanks. Traders have spent three months betting on an imminent peace deal, often ignoring the logistical lag time required to restart supply chains. Even if the Strait were opened today, it would take weeks for tankers to reach buyers. Meanwhile, China has been a significant factor in delaying the price impact by drawing down its own reserves, which were estimated at over 1.2 billion barrels before the conflict began.
Comparison of Market Perspectives
| Market Actor | Primary Outlook |
|---|---|
| Futures Traders | Focused on diplomatic sentiment and potential for a quick supply surge. |
| Industry Executives | Focused on physical inventory depletion and imminent price spikes. |
Watch for shifts in Chinese import data. Because China acted as a major buffer in the early stages of this crisis, any move by Beijing to stop selling from reserves and return to the global market as a buyer will likely accelerate the depletion of remaining global stocks.
Frequently Asked Questions
Why don’t oil prices reflect the 13 million bpd supply loss?
Prices have been artificially capped by the release of strategic reserves, the use of “oil on water,” and the availability of de-sanctioned Russian crude. Furthermore, demand destruction is currently acting as a final, albeit insufficient, buffer.

How long would it take to restore supply if the Strait opens?
According to market analysts, even with an immediate resolution, it would take weeks or months for cargoes to physically reach buyers and restore global supply chains to pre-conflict levels.
What is the role of the U.S. in this supply crisis?
The U.S. has been a primary negotiator in the conflict. However, the market remains volatile due to the uncertainty of Iranian demands regarding operational control of the Strait and the potential for further military escalations.
