The 700-Million-Barrel Oil Shock

Based on the projection from the Kepler Institute, by the final week of April 2026, the cumulative deficit in oil supply resulting from the closure of the Strait of Hormuz will hit 700 million barrels.

The closure of the Strait of Hormuz has presented the world with one of the most critical oil supply disruptions in modern history and has driven prices sharply upward. Unlike past shocks triggered by wars or embargoes, this blockage strikes at the very jugular of global energy logistics.

According to a fresh assessment by the Kepler Institute, an ongoing halt to oil tanker transit through the Strait of Hormuz until the end of April 2026 could push the global energy market into an extraordinary crisis, bringing the total oil supply deficit caused by this closure to approximately 700 million barrels. This drop in supply has triggered one of the largest oil shocks of the current era. By April 12, around 300 million barrels of oil had been removed from the supply chain due to the stoppage of traffic through this vital chokepoint — a corridor that carries roughly 20% of the world's daily oil demand.

In the wake of this disruption, Brent crude oil prices have surpassed US$100 per barrel, and the cost of refined products such as jet fuel has risen above US$200 per barrel — a scenario that has set off the phenomenon of demand destruction, leading airlines to cancel numerous flight routes, consumer countries to impose fuel rationing and mandatory remote work, and the International Energy Agency to revise downward its 2026 oil demand growth forecast.

Meanwhile, Saudi Arabia, by leveraging the full capacity of its East-West pipeline, and the United Arab Emirates, via the Fujairah export route, are attempting to offset part of the supply shortfall.

Conversely, Iraq has been largely incapacitated, with its exports collapsing from 4 million to less than 900,000 barrels per day. Without immediate diplomatic intervention, smaller Persian Gulf states may soon follow Iraq into paralysis.

Kepler cautions that even if the crisis is resolved immediately, the process of market recovery will not be swift, and the volume of lost oil could reach one billion barrels before the supply chain is fully restored. 

Two potential paths lie ahead for the market. In the favorable scenario, limited demand contraction and a gradual easing of the crisis over the next several weeks are anticipated. However, in the unfavorable scenario, continued disruption into the third quarter of the year could push oil prices toward US$190 per barrel and cause demand destruction on the order of several million barrels per day — an outcome that would be even more severe than the oil crisis of the 1970s.
