KEY POINTS
- U.S. crude inventories fell by 9.12 million barrels in the week ending June 5, the largest single-week draw since March, pushing WTI back above $88 and Brent toward $93.
- The Strait of Hormuz remains effectively closed — only seven ships transited Friday versus the normal 100 per day — creating the largest oil supply disruption in modern history.
- If inventory draws continue at this pace through June, analysts warn stocks will hit operational minimums and Brent could break back above $100 within weeks.
U.S. crude oil inventories plunged by 9.12 million barrels in the week ending June 5, the steepest single-week draw since the first days of the Hormuz closure in March, and a clear signal that the market's brief period of relative calm on energy prices is ending.
West Texas Intermediate crude climbed 0.8% to $88.97 a barrel on Tuesday before fresh U.S. strikes on Iran pushed it higher overnight, with prices touching $91.54 in early Wednesday trading. Brent futures rose 0.9% to $92.29 before pulling back slightly as an Iran-Israel mutual ceasefire announcement briefly tempered fears, though that ceasefire now appears fragile at best.
The Strait Nobody Can Open
The fundamental problem has not changed in four months: the Strait of Hormuz is closed, and nobody has a credible plan to reopen it. Under normal circumstances, roughly 100 cargo vessels transit the waterway daily, carrying approximately 25% of the world's seaborne oil and 20% of global LNG. As of this past weekend, only seven ships transited on Friday, followed by four more over the weekend, according to data from research firm Kpler.
The IEA has described this as the largest supply disruption in the history of the global oil market, with outputs from affected countries down more than 14 million barrels per day at the peak of the crisis. While some alternative routing through the Cape of Good Hope has partially offset the shortfall, the logistical penalty is enormous — an extra 10 to 14 days of transit time per voyage, tying up tanker capacity and inflating shipping costs.
Global oil inventories reflect the damage. OECD inventories are forecast to fall to just 50 days of forward demand cover by year-end, which would be the lowest level since January 2003. At the current pace of draws, the U.S. will exhaust its operational buffer by late July.
Price Has Not Caught Up to Fundamentals
Here is what should worry energy traders: despite the most severe supply disruption in half a century, Brent crude is trading at $92, well below its March wartime peak above $120. The reason is twofold. First, demand destruction in emerging markets has partially offset the supply loss, with countries like India and Pakistan cutting fuel subsidies and rationing imports. Second, the U.S. Strategic Petroleum Reserve releases in April and May added roughly 2 million barrels per day of temporary supply.
Both of those cushions are running out. SPR releases have slowed to a trickle as the reserve approaches minimum operational levels, and demand in the Northern Hemisphere is about to enter peak summer driving season. Morgan Stanley's commodities desk is now forecasting Brent will average $130 in July and August if the strait remains closed, a 40% premium to today's price.
For traders, the inventory data matters more than the headline geopolitical noise. Tuesday night's strikes were dramatic, but they did not materially change the supply picture — the strait was already closed. What the 9.12-million-barrel draw tells you is that the market is structurally undersupplied right now, even without further escalation. Each weekly draw of this magnitude brings the break above $100 closer.
What Comes Next
The EIA's Short-Term Energy Outlook, due Thursday, will provide updated forecasts on global supply and demand balances. Traders should also watch API inventory data next Tuesday for confirmation of whether draws are accelerating. If oil inventories continue to deplete at this rate through June, the math becomes unavoidable: prices need to rise to destroy enough demand to rebalance the market.
The energy complex remains the single most important variable for every other asset class in 2026. CPI, corporate earnings, consumer spending, and Fed policy all flow through oil prices. Until the Hormuz crisis resolves — and there is no sign it will — energy is the trade that matters.
