The Strait of Hormuz Crisis: Who Really Controls Global Energy?

The Hormuz Crisis 2026 has exposed the fragile foundations of the global energy system, where a narrow strait can disrupt economies worldwide.

As tensions escalate between major powers and regional actors, the Strait of Hormuz has become more than a trade route; it is now a strategic pressure point shaping oil prices, supply chains, and political decisions.

This crisis highlights how deeply interconnected modern economies are, with distant conflicts quickly impacting everyday life. Understanding the Hormuz Crisis 2026 requires looking beyond headlines to the underlying structures of power, dependency, and vulnerability that define today’s global energy landscape.

The Strait of Hormuz, a narrow waterway between Iran and Oman connecting the Persian Gulf to the Arabian Sea, serves as one of the world’s most critical energy chokepoints. In normal times, approximately 20 million barrels per day of crude oil, condensate, and refined petroleum products transit this passage, equivalent to about 20% of global petroleum liquids consumption and roughly one-quarter of all seaborne oil trade. Additionally, around 20% of global liquefied natural gas (LNG) flows through the strait, primarily from Qatar, with significant volumes heading to Asian markets.

This geographic bottleneck underscores a fundamental vulnerability in the global energy system: a relatively small stretch of water, bordered by an adversarial state on one side, holds disproportionate sway over energy prices, supply chains, and economic stability worldwide.

The 2026 Crisis Unfolds

In late February 2026, coordinated U.S. and Israeli military strikes against Iran escalated into open conflict. Iran retaliated by targeting vessels and infrastructure, effectively declaring the strait “closed” by early March. The Islamic Revolutionary Guard Corps (IRGC) warned that ships attempting transit could face attacks, leading to a near-total collapse in commercial shipping. Daily vessel transits dropped from an average of 100–138 to just a handful, with tanker traffic plummeting to near zero at times.

Iran advanced legislation to impose tolls and ban U.S. and Israeli-affiliated vessels. Attacks on tankers, including incidents involving fires and injuries, compounded the disruption, alongside reports of mines, drones, and missile threats. By late March, the International Energy Agency described it as the most acute supply disruption in global energy market history. Gulf oil production was slashed by over 11 million barrels per day due to storage constraints and halted exports.

The impacts rippled globally:

• Market Shocks: Oil prices surged toward or into triple digits in scenarios of prolonged closure.
• Asian Paralysis: Asian economies, China, India, Japan, and South Korea, which receive 80% or more of the Strait’s oil and LNG flows, faced acute shortages.
• European Strain: Europe experienced heavy secondary effects through higher LNG and energy costs.
• Food Security: Fertiliser shipments, which typically account for one-third of global seaborne trade, passing through the strait raised fears of food price spikes and supply chain crises.

Alternative routes offered limited relief. Saudi Arabia’s East-West pipeline to the Red Sea and UAE pipelines could divert only a fraction of volumes (estimated at 2–5 million barrels per day combined). Meanwhile, Qatar’s LNG infrastructure suffered damage, threatening long-term export capacity.

Iran’s Leverage: Geography as a Weapon

Iran has long viewed the strait as its ultimate strategic asset. As the coastal state controlling key islands and the northern approaches, Tehran claims effective sovereignty or at least the practical ability to disrupt transit. Iranian officials and the IRGC have repeatedly asserted “complete control” over the waterway, threatening to turn it into a “strait of defeat and suffering” for adversaries.

This is not mere rhetoric. Iran’s asymmetric capabilities, including anti-ship missiles, fast-attack boats, mines, and drones, allow it to impose high costs on naval forces attempting to enforce passage without a massive, sustained campaign. Even after the reported destruction of much of Iran’s surface navy and mine-laying assets by U.S. strikes, traffic remained functionally halted into April 2026.

Under international law, the strait qualifies for “transit passage” rights under customary interpretations of the UN Convention on the Law of the Sea (UNCLOS), which Iran has not ratified but which many view as binding custom. Coastal states cannot impede innocent or transit passage in such straits. Yet enforcement relies on power, not parchment. Iran’s position as a bordering state gives it de facto veto power in a crisis, especially when it perceives existential threats.

The International Response and Limits of Naval Power

The United States, traditionally the guarantor of freedom of navigation in the Gulf, faces severe constraints. President Trump issued strong warnings, threatened escalated strikes on Iranian infrastructure (including power plants and Kharg Island), and floated naval escorts and political risk insurance for tankers. The U.S. Navy conducted strikes on Iranian vessels and maintained a presence via the 5th Fleet, but carriers operated outside missile range, and full reopening efforts appeared cautious due to risks of costly attrition warfare.

Allies issued joint statements supporting safe passage and calling for coalitions involving European, Gulf, and Asian navies. Proposals for international convoying and long-term “internationalisation” of security emerged, but implementation lagged. This delay was exacerbated by commercial realities: Lloyd’s of London and other maritime insurers effectively “closed” the strait to commercial traffic by hiking war risk premiums to unaffordable levels or cancelling coverage entirely.

This reveals a core asymmetry: Iran does not need to “own” the strait outright; it only needs to make passage prohibitively dangerous or expensive. Major powers, despite superior conventional forces, hesitate before committing to open-ended operations in contested littoral waters dominated by cheap, precision-guided threats.

Who Really Controls Global Energy?

The crisis reveals that no single actor holds absolute control; influence flows from vulnerability and leverage.

• Geography and Proximity: This grants Iran outsized disruptive power. A mid-tier regional power can paralyse a vital artery of the global economy, forcing even superpowers into difficult calculations.
• Market and Consumer Dependence: This empowers exporters and chokepoint states. Asia’s heavy reliance amplifies the pain, turning local conflict into a global energy shock. China, in particular, finds itself in an awkward position—forced to balance its strategic partnership with Tehran against the reality that Iran is actively starving the Chinese economy of the energy it needs.
• Naval and Military Superiority: This provides the United States and its coalitions with the potential to eventually restore flows, but at a high cost in blood, treasure, and political capital. History—from the “Tanker War” of the 1980s to freedom of navigation operations—shows sustained commitment is required, not one-off strikes.
• Diversification and Resilience: Ultimately, these factors determine true control. Nations with strategic reserves, alternative pipelines, domestic production (e.g., U.S. shale), or accelerated renewable transitions suffer less. The crisis has renewed debates on energy security, highlighting the fragility of fossil fuel dependence and making the case for faster shifts to renewables, even if immediate transitions remain limited by current supply chain realities.

In reality, global energy “control” is distributed and contested. Producers, consumers, transporters, and military actors all hold pieces of influence. The Strait Crisis demonstrates that in an interconnected world, control is illusory; interdependence creates shared vulnerabilities that can be exploited by the determined few. Iran does not dictate global energy prices in peacetime, but in conflict, it can impose massive costs on everyone.

Lessons and the Path Forward

The 2026 Strait of Hormuz crisis serves as a stark reminder of the enduring strategic weight of energy chokepoints. Long-term solutions demand more than naval patrols: accelerated investment in bypass infrastructure, diversified supply sources, strategic stockpiles, and reduced reliance on volatile regions. International diplomacy and deterrence must balance firmness with de-escalation to prevent repeated disruptions.

Ultimately, no one “really controls” global energy in absolute terms. The system is a complex web of physical geography, economic incentives, technological alternatives, and military realities. The crisis underscores humanity’s collective interest in keeping critical sea lanes open, not through dominance by any one power, but through norms, cooperation, and resilience that transcend narrow national interests. Until energy systems evolve beyond such narrow bottlenecks, the world will remain hostage to crises like this one, where a narrow strait reveals the limits of power and the breadth of global interdependence.
