The Strait of Hormuz: A High-Stakes Waterway
The Strait of Hormuz, a critical passage for global energy trade, is not completely closed despite the ongoing tensions between the U.S., Israel, and Iran. Several brave ship captains have taken risks to transport cargo through this narrow waterway, with some claiming to be Chinese. This bold move highlights the strategic importance of the strait, as it serves as a vital route for a significant portion of the world’s oil and liquid natural gas.
Tanker traffic has largely come to a standstill since the U.S. and Israel launched a war against Iran. In response, Iran has retaliated by launching missiles and drones at Gulf neighbors and ships carrying energy resources around the globe. This disruption has led to a sharp increase in prices, creating a challenging situation for global markets.
Economic Implications of Disruption
Approximately 20% of the world’s oil and liquid natural gas pass through the Strait of Hormuz. The sudden halt in traffic has sent prices soaring, but this spike also presents an opportunity for ships willing to make deliveries. Freight rates have reached record highs, with a very large crude carrier heading from the strait to China potentially earning about $500,000 in revenue per day.
Over the past week, at least 10 ships have altered their transponder signals to indicate “Chinese Owner,” “All Chinese Crew,” or “Chinese Crew Onboard,” according to MarineTraffic data analyzed by the Financial Times. For example, one ship called the Iron Maiden briefly changed its signal to say “China owner” as it navigated through the strait on Wednesday.
Strategic Importance of the Strait
About half of China’s oil imports must traverse the strait, and 90% of Iran’s oil supply ends up in China, often via third countries to evade sanctions. As a result, Tehran relies heavily on these shipments for revenue and is sensitive to the perception that its military is preventing tankers from reaching its ally.
However, “Chinese” isn’t the only identity being used by ships. The Financial Times pointed to an instance last weekend when a fuel tanker called Bogazici crossed the strait while temporarily identifying itself as “Muslim Vsl Turkish.” This practice underscores the complexity of navigating the strait amid geopolitical tensions.
Government Interventions and Challenges
To encourage shippers to get their cargoes out of the Gulf and ease global energy markets, President Donald Trump announced a $20 billion reinsurance program for oil tankers and other maritime traffic. Analysts have noted that the threat of getting blown up by Iranian projectiles is a bigger obstacle than getting insurance coverage. Therefore, Trump has also stated that the U.S. Navy will escort tankers through the strait if necessary.
Despite these efforts, Wall Street remains unconvinced. On a normal day, 60 tankers—and as many as 90—go through the Strait of Hormuz. Leading up to the start of the war last weekend, the Navy had two aircraft carriers and 16 surface warships in the Middle East, marking its largest presence in the region since the Iraq war began in 2003.
Naval Capabilities and Logistical Challenges
According to the Center for Strategic & International Studies, the Navy’s fleet consists of 233 commissioned warships, and 59 are support ships. However, most are in port or undergoing maintenance and training, with less than a fifth of the force at sea for operations. As of late February, just 49 Navy ships were at sea conducting operations.
Meanwhile, the U.S. and its Gulf allies have faced challenges in shooting down Iran’s Shahed drones, which have hit several major military targets. Robin Brooks, a senior fellow at the Brookings Institution, highlighted the logistical difficulties of protecting so many ships. He wrote in a Substack note that all Iran needs to do is sneak through a couple of drones to blow up one ship, leading to a massive oil shock.
