The Strait of Hormuz crisis has left global oil markets with a roughly 500 million barrel inventory hole that will take more than a year to refill, even as a wave of Asian nations races to build strategic reserves.

Global oil markets face a structural supply deficit of roughly 500 million barrels after the Strait of Hormuz disruption, with the International Energy Agency forecasting the shortfall will persist through the fourth quarter of 2026 even if the waterway reopens this month, according to S&P Global data. The chokepoint, which previously handled nearly 20 percent of global oil supply, still has about 100 million barrels of crude backlogged, and each additional day of closure adds 5.8 million barrels to the deficit.
"Importing governments are only asking one question: 'What do we need to do to make sure this never happens again?'" said Kevin Book, co-founder of ClearView Energy Partners, an energy research firm.
Abu Dhabi National Oil Co. Chief Executive Officer Sultan Ahmed Al Jaber said restoring traffic through the Strait of Hormuz to 80 percent of pre-crisis levels will take four months, with full recovery not expected until the first or second quarter of 2027. Saudi Aramco has given a similar timeline. Even if the market suddenly gained 1 million barrels a day of surplus supply, S&P Global estimates it would take more than a year for global inventories to return to pre-crisis levels. The IEA expects a small surplus to emerge only in the fourth quarter, allowing stockpiles to begin replenishing.
The supply shock is reshaping energy security strategies across Asia, where governments are racing to build strategic petroleum reserves from scratch or expand existing stockpiles. Pakistan, which had no strategic reserves, is planning its first storage system and inviting international producers to build commercial inventories at Port Qasim near Karachi. The Philippines is establishing its first strategic petroleum reserve, while Indonesia announced new storage facilities and India is expanding its existing capacity. Japan has pledged $10 billion in financial assistance to support Asian nations in building storage infrastructure.
Production recovery will be uneven. Saudi Arabia and the United Arab Emirates, which left OPEC last month and is no longer bound by output quotas, both have spare capacity and can ramp up production relatively quickly. Iraq and Kuwait face a slower recovery because of their reliance on foreign oilfield service companies and the technical challenge of re-pressurizing aging, low-pressure wells.
The crisis is also accelerating a broader rethinking of energy mix. European Union ministers are discussing whether to expand domestic oil and gas production — a debate that was nearly unthinkable just a few years ago. At the same time, cheap Chinese electric vehicles and solar panels are giving import-dependent nations more options to reduce fossil fuel reliance. Ember data shows 50 countries set records for Chinese solar panel imports in March alone.
History suggests energy shocks can trigger lasting structural change. The oil crises of the 1970s pushed the U.S. to aggressively improve energy efficiency and develop alternative sources; oil now accounts for about 1 percent of U.S. electricity generation, down from nearly one-fifth in the early 1970s. But a meaningful energy transition takes time. In the interim, the overwhelming priority for governments remains securing supply — and that means stockpiling crude, a dynamic that will keep the oil market tight and prices elevated for an extended period.
