That conclusion is now taking hold across the market. In the latest Reuters analysis of the crisis, Gulf energy officials and buyers describe a market in which even a Western declaration that the fighting is winding down would not, by itself, restart normal tanker traffic. The bottleneck is no longer whether consuming nations can find emergency oil. It is whether shipowners believe the world’s most important energy lane is safe enough to use again.
Why the Strait of Hormuz still matters more than the reserve release
The IEA has already deployed its strongest short-term tool. Its 400 million-barrel emergency release is the largest coordinated stock action in the agency’s history, and Executive Director Fatih Birol said the oil market challenges are “unprecedented in scale.” That intervention matters because it buys time for refiners and governments facing a sudden supply shock.
But time is all it buys. A more detailed Reuters account of the rollout shows that some barrels in Asia and Oceania are available immediately, while stocks from Europe and the Americas will reach the market later in March. That helps calm panic, yet it does not solve the physical problem of vessels avoiding Hormuz, producers cutting output and insurers repricing risk while attacks and threats continue.
The numbers explain why the reserve release cannot fully replace normal traffic. EIA’s latest chokepoint data show roughly 20 million barrels a day moved through Hormuz in 2024, equal to about 20% of global petroleum liquids consumption. The same passage also carried about one-fifth of global LNG trade. Saudi Arabia and the United Arab Emirates can bypass some cargoes, but EIA estimates only about 2.6 million barrels a day of spare alternative pipeline capacity is readily available — far below the volumes usually exposed to the strait.
Strait of Hormuz security, not oil stock size, is now the market test
The EIA’s latest short-term outlook makes the market logic even clearer: the strait is not physically blocked in the classic sense, but the threat of attack and the loss of insurance coverage have still been enough to push tankers away and force production shut-ins. That turns the crisis into a confidence shock as much as a supply shock.
That also explains why escort ideas or headline declarations of de-escalation may not be enough on their own. If owners, crews and insurers still think a tanker can be hit by drones, missiles or mines, the waterway can remain effectively frozen even without a formal blockade. In practical terms, Tehran now holds leverage not because it can keep every ship out forever, but because it can keep enough doubt in the market to delay a full return to ordinary flows.
For consuming nations, especially in Asia, that distinction is crucial. Emergency reserves can fill a gap for weeks. They cannot quickly replace a trade artery that carries such a large share of seaborne oil and gas, nor can they instantly reverse production shut-ins once storage backs up behind the chokepoint. Until commercial confidence returns, any relief from stockpiles is more bridge than breakthrough.
Strait of Hormuz tensions have a long recent history
The current shock also fits a pattern that markets know well. The 2019 Gulf of Oman tanker attacks showed how quickly explosions near Hormuz can jolt prices and revive fears of direct U.S.-Iran confrontation. The 2023 seizure of the Advantage Sweet proved that commercial shipping remained vulnerable even after that earlier scare faded. And the 2022 IEA release after Russia’s invasion of Ukraine set the previous benchmark for emergency action — a record the agency has now shattered, which underlines how severe the present disruption has become.
That history helps explain why traders are not treating this as a brief geopolitical premium that disappears the moment more oil is promised from storage. They are treating it as a crisis of access, confidence and durability — one in which the return of ordinary Gulf exports depends less on how many barrels consuming nations can release than on whether Iran decides continued disruption no longer serves its interests.
Until that changes, the record IEA drawdown is best seen as a stabilizer, not a reopening mechanism. It can soften the blow to refiners, utilities and households, but the decisive switch for global energy markets still sits at the Strait of Hormuz.
