Stress Test: The Hormuz Crisis and the Fracturing of the Global Energy Order

The global energy system has entered a period of acute structural stress following the strikes by the United States and Israel on Iran in late February 2026, and the subsequent disruption of flows through the Strait of Hormuz. According to the International Energy Agency, the resulting shock marks the most severe disruption to global energy markets since the 1970s oil crises, with systemic characteristics comparable to the combined effects of those crises and the 2022 Russia-Ukraine energy shock. This policy paper examines the mechanics of the oil-price shock, then assesses the structural importance of the Strait of Hormuz as a global energy chokepoint, through which an estimated 17.8 million barrels per day of crude oil and LNG transited before the Iran conflict. It highlights the limited substitutability of existing bypass infrastructure under conditions of sustained disruption. It also evaluates the fragmentation of the OPEC+ framework, including the United Arab Emirates’s announced withdrawal from the alliance on May 1, 2026, marking a critical point in the erosion of coordinated production management among major Gulf exporters. Finally, it analyses the role of renewable energy as a structural variable in the crisis, not as a short-term buffer, but as an accelerating force reshaping the geopolitical foundations of energy security. The Hormuz disruption should therefore be understood not only as a price shock, but as a systemic stress test of global energy governance, exposing deep structural fragilities and accelerating realignments across markets, alliances, and the energy transition.
