The End of Easy Energy: Life After the Hormuz Blockade

For much of the 2010s and 2020s, global markets operated under the assumption that energy security was a solved problem. Countries from Europe to the Far East have been content to outsource their Liquefied Natural Gas (LNG) and oil needs to imports from the Gulf states of Qatar, Saudi Arabia, and the United Arab Emirates. This complacency evaporated in February 2026, following the joint US-Israeli Operation “Epic Fury” and the Iranian regime’s announcement of the closure of the Strait of Hormuz. 

Geographically, the Strait of Hormuz is a narrow tunnel separating the Persian Gulf from the Gulf of Oman, measuring only 21 miles wide at its narrowest point. It serves as a chokepoint facilitating the transit of approximately 20 million barrels of oil per day, roughly one-fifth of global consumption. The narrow strait’s proximity to the Iranian mainland has left any maritime vessel vulnerable to ballistic missiles and drone attacks – consequently, the world’s leading maritime risk insurer, Lloyd’s of London, began cancelling war premiums for ships almost immediately after the war began. Since the Iranian Revolutionary Guard Corps (IRGC) announced the official closure of the strait, there have been several attacks on commercial vessels and maritime traffic has significantly dropped for all countries.

The strategic importance of the Strait of Hormuz is underlined by a lack of viable alternatives. The East-West Pipeline, which traverses Saudi Arabia, offers potential relief, but with a capacity of around 2.5 million barrels of oil per day (with other pipelines having even less), it pales in comparison to the sheer volume passing through the Strait. Any kind of disruption to shipping lanes creates and immediate bottleneck that cannot be easily mitigated, and which may take months to fully resolve itself. In the meantime, oil prices have spiked to over $100 a barrel as of 21 March, with significant economic and political consequences to countries all over the world.

Firstly, the United States. A significant drop in GDP is expected, ranging from a drop of 0.2% to 1.3% if the Strait remains closed for several quarters. Since the shale oil boom, the US has reduced its dependency on imported petroleum, meaning they are somewhat shielded from the global impacts. The bigger concern for the current administration is political, not economic. Midterms are looming in November, and current polling of Americans suggest widespread disapproval of the direction the war is taking. With rumours of possible “boots on the ground” to facilitate the reopening of the Strait, along with a resilient Iranian regime unlikely to be toppled, memories of Iraq loom in the public consciousness. Stuck between a political rock and an economic hard place, the Trump administration may face a political blowback regardless of their actions.

Japan, which imports around 80% of its energy, released 80 million barrels of oil from its strategic reserves in an effort to maintain economic stability without military intervention. India, facing shortages of gas and crude oil as exports plummet, have begun negotiations with Tehran to secure safe passage through the Strait. The crisis has illustrated the importance of shifting towards diversified energy strategies and an acknowledgement that dependence on oil from the Persian Gulf is not sustainable under the current volatile geopolitical conditions.

Europe, on the other hand, is facing yet another crisis. Just as the European Central Bank and the Bank of England were signalling an easing of inflation and interest rates, the Strait closure has thrown a spanner in the works. For the first time in four-and-a-half years, the Bank of England’s committee voted unanimously to hold interest rates steady at 3.75%, with the governor indicating that rises may be on the table if the conflict continues to affect inflation. The UK is heavily dependent on LNG imports from Norway, the US, and the Persian Gulf, both for domestic heating and electricity generation. A second cost-of-living crisis is very much still on the cards.

Ultimately, the Hormuz crisis serves as a stress test for the globalised world. A single closure of a narrow, 20-mile body of water has caused massive ripples in the global energy markets. The long-term ramifications for policymakers are clear: under the current geopolitical climate, energy independence has become a crucial strategic priority, and nations cannot rely upon imports to fuel their economies. Even if the Strait was opened tomorrow, these lessons will remain: the world is changing, and electricity is more important than ever.
