The Strait of Hormuz: A Global Energy Chokepoint Under Fire

The Strait of Hormuz has transitioned from a strategic maritime passage to a primary front line in the ongoing Middle East war. As attacks on commercial vessels intensify, this critical waterway—through which 20% of the world’s crude oil and liquefied natural gas (LNG) normally flows—is facing a near-total blockade. The result is a mounting crisis for global energy security and a direct threat to the international economy.

The Scale of Maritime Attacks

The conflict has seen a surge in targeted strikes against commercial shipping. According to data from Windward Daily Intelligence, 22 vessels have been attacked since the start of the conflict. The Iranian Revolutionary Guards have specifically claimed drone strikes on the tankers Prima and Louis P, as well as the asphalt/bitumen tanker Athe Nova.

Reporting from the UK Maritime Trade Operations (UKMTO), the International Maritime Organization (IMO), and Iraqi and Iranian authorities identifies at least 10 oil tankers that have been hit or targeted, including:

• UKMTO Reported: Skylight, MKD Vyom, Hercules Star, Ocean Electra, Stena Imperative, Libra Trader, and Sonangol Namibe.
• Iraqi Authorities Reported: Safesea Vishnu and Zefyros.

The violence extends beyond oil tankers. Four bulk carriers, three container ships, a tugboat, an oil drilling vessel, and a cargo ship have reported explosions or suspicious activity. In one critical incident, Thailand’s navy reported an attack on the bulk carrier Mayuree Naree. while Oman’s navy rescued 20 crew members, three remain missing.

A Paralyzed Waterway: Transit Data

The strategic blockade has led to a sharp decline in maritime traffic. On April 2, 2026, transit activity plummeted to just nine total transits: one inbound and eight outbound.

Inbound and Outbound Trends

The sole inbound vessel recorded on April 2 was the Pacific Star, a Panama-flagged LPG tanker under Turkish commercial control. Outbound traffic consisted primarily of cargo vessels flying flags from Panama, Comoros, the Marshall Islands, Taiwan, Liberia, and Malta. Greek ownership remains prominent in these movements, accounting for four of the 12 identified ownership entries, with French ownership also appearing in recent reporting cycles.

The “Dark Activity” Phenomenon

The risk environment has forced many ships to operate covertly. Out of 656 active vessels currently in the Gulf—comprising 358 cargo ships and 298 tankers—72 are engaged in “dark activity,” meaning they have turned off their Automatic Identification System (AIS) to avoid detection and potential targeting.

Global Economic Repercussions

Iran’s strategy to inflict “maximum pain” on the global economy in retaliation for US-Israeli strikes is manifesting in volatile energy markets. The disruption of the Strait of Hormuz has triggered immediate economic pressure, including:

• Energy Price Hikes: The blockade is driving up global oil prices, leading to petrol and electricity hikes in various regions.
• Supply Chain Fragmentation: The risk to commercial shipping is creating broader pressures on the global oceans economy.

In response to the escalating crisis, US President Donald Trump has urged countries dependent on the oil flowing through the strait to take greater responsibility for keeping the passage open, promising American support for these efforts.

Key Takeaways: The Hormuz Crisis

• Critical Volume: 20% of global crude and LNG passes through the strait.
• Attack Volume: 22 vessels attacked since the conflict began.
• Transit Collapse: Daily transits have dropped to single digits (9 total on April 2).
• High-Risk Tactics: 72 vessels are currently operating “dark” (AIS off) to avoid strikes.

Looking Ahead

The Strait of Hormuz remains a high-risk zone where commercial shipping is effectively being used as leverage in a larger geopolitical conflict. With a tiny fraction of normal traffic navigating the waterway and insurance premiums and reroute costs climbing, the stability of the global energy market depends entirely on whether international coalitions can successfully reopen and secure this essential chokepoint.
