Why Oil Isn't at $150
The Strait of Hormuz has been effectively closed since February 28. That is nearly four months of disruption to roughly 20% of global oil supply, one of the largest energy shocks in modern history. By conventional models, oil should be catastrophically expensive.
It isn't. Brent crude averaged $107 per barrel in May, down from $117 in April. The Energy Information Administration is forecasting $105 for June and July. Markets looked at a 20% supply cut and decided not to panic.
That response is worth examining, because the reasons prices have stayed down are not structural. They are temporary.
Three things are suppressing the price: coordinated releases from strategic petroleum reserves in the United States, Europe, and Japan; a sharp reduction in Chinese oil imports, down nearly 3 million barrels per day due to slowing refinery demand; and Saudi Arabia rerouting some flows around the Cape of Good Hope. Remove any one of these and the math breaks.
The SPR Is a Finite Instrument
Strategic petroleum reserves are emergency buffers. They are not supply replacements.
In March, the International Energy Agency approved its largest-ever coordinated release: 400 million barrels across member nations. The number sounds significant. Measured against daily global demand of roughly 103 million barrels, it covers less than four days of consumption.
What SPR releases actually do is buy time. Time for tanker logistics to adjust, for alternative supply routes to form, for diplomacy to move. The problem is that the time being bought is running out faster than the headlines suggest.
The IEA's June report shows global observed oil stocks fell by 143 million barrels in May alone, a draw of 4.6 million barrels per day. OECD inventories are projected to fall to a 50-day supply cover by the end of 2026. That would be the lowest level since January 2003. The buffers are depleting at a record rate.
Who Gets Forced
The hardest-hit buyers in this scenario are in Asia: China, Japan, South Korea, and India. These countries depend on Hormuz flows in ways the United States and Europe do not.
Atlantic Basin crude has been rerouted east, adding roughly 3.5 million barrels per day to non-Gulf supply chains. But tanker routes around Africa add weeks to delivery times and costs that compound at scale.
China's import reduction is currently the market's largest shock absorber, larger than the coordinated SPR releases, according to analysts at Societe Generale. But reduced Chinese imports are not a sign of resilience. They reflect demand destruction. When Chinese refinery activity recovers, that 3-million-barrel-per-day buffer disappears quickly.
The Failure Path
The most likely failure scenario does not involve escalation. It involves a quiet inventory drain that markets have not yet priced.
Here is the sequence: the Strait partially reopens in the third quarter, as both the EIA and IEA project. Markets price in relief. Oil sells off toward $89 to $90 per barrel. But the SPR is largely depleted, OECD inventories are at historic lows, and the rebuild cycle creates sustained demand above normal consumption for months. Tanker rates stay elevated because vessel routing and crew logistics do not normalize overnight. Refinery margins stay compressed because product flows remain irregular.
The apparent relief becomes a trap. The structural tightness that builds through late 2026 into 2027 is the real risk. Not the disruption itself, but the inventory hole the disruption dug.
What I'm Watching
Three signals matter most. First, the pace of OECD inventory draws in June and July. If the monthly draw stays above 4 million barrels per day, the year-end supply cover math gets alarming. Second, Chinese refinery utilization rates. Any uptick in Chinese demand signals the import buffer is reversing. Third, IEA member compliance on SPR commitments. Coordinated releases only work if every member delivers what it pledged.
The IEA's June report noted that Hormuz shipments rose to around 12 million barrels per day in early June, up from a May low of 9.6 million. Pre-conflict flows ran at approximately 20 million barrels per day. Markets are behaving as though the problem is close to solved. At 60% of normal throughput, it is not.
How This Thesis Fails
If China's demand destruction proves structural rather than cyclical, the import buffer holds longer than expected and inventory draws slow. The EIA's own forecast already assumes a meaningful reduction in global demand. If demand stays lower even after flows normalize, inventories rebuild faster and any price correction in 2027 comes sooner and sharper.
Full normalization by August would also break this thesis. If the Strait reopens on an accelerated schedule and Saudi Arabia restores pre-conflict production volumes immediately, the inventory danger window closes before it becomes a crisis.
Closing Thoughts
Oil staying below $150 during a closure of one of the world's most critical energy chokepoints is not evidence that markets handled the shock well. It is evidence that every available emergency tool was deployed at once. The SPR is a one-time instrument. China's reduced imports are temporary. Saudi rerouting has physical limits.
When the Strait reopens and markets respond with relief, the question that matters is not whether supply returns. It is whether inventories can be rebuilt before the next disruption finds the tank empty.
The calm is borrowed time.
Plain English
Even though one of the world's most important oil shipping routes have been disrupted for over four months at this point, the price at the gas pump hasn't risen nearly as high as experts initially expected. I argue this because governments have been using emergency reserves, China has been buying less oil due to slower economic activity, and producers have found temporary ways to reroute shipments. Although these have kept prices stable for now, they aren't permanent solutions. Once these emergency supplies start running low and demand picks up again, you may start seeing higher gas prices, even after the current crisis ends.
