Dubai: Some of the world’s busiest maritime chokepoints are becoming the latest flashpoints in global geopolitics. Iran’s proposal to charge vessels transiting the Strait of Hormuz, coupled with reports that Yemen’s Houthi movement is considering similar measures in the Bab el-Mandeb Strait linking the Red Sea to the Gulf of Aden, has reignited debate over who has the authority to regulate international waterways—and what the consequences could be for global trade.
The Strait of Hormuz and the Bab el-Mandeb are among the world’s most important maritime chokepoints. Together, they connect oil-producing Gulf nations with global markets and serve as critical routes for container shipping between Asia, Europe, and Africa.
Why These Waterways Matter
Every day, millions of barrels of crude oil, liquefied natural gas, and manufactured goods pass through these narrow passages. Any disruption can ripple through international supply chains, affecting fuel prices, shipping costs, and global inflation.
Iran’s Proposal Raises Legal Questions
Iran has argued that ships passing through the Strait of Hormuz should pay for services such as navigation, security, and environmental protection. Tehran maintains that, given its geographic position and security responsibilities, it has the right to regulate traffic through waters under its control.
However, many maritime law experts point to international legal frameworks, particularly the United Nations Convention on the Law of the Sea (UNCLOS), which generally protects the right of transit passage through international straits used for global navigation. Whether unilateral transit charges would comply with international law remains a matter of legal and diplomatic dispute.
The Red Sea Could Become the Next Flashpoint
Attention is also turning to the Bab el-Mandeb Strait, where Yemen’s Houthi movement has reportedly explored adopting a strategy similar to Iran’s by exerting greater control over shipping routes.
Regional officials warn that if commercial vessels face restrictions or additional fees in both Hormuz and the Red Sea, global maritime trade could experience unprecedented pressure, particularly for energy shipments and Europe-Asia commerce.
How Are International Straits Normally Governed?
Unlike canals such as the Suez Canal or Panama Canal—which are managed by national authorities and charge transit fees—most international straits operate under international maritime law.
Key waterways including the Strait of Hormuz, Bab el-Mandeb, and the Strait of Malacca generally allow ships from all nations to pass without requiring permission from coastal states, provided they comply with internationally recognized navigation rules. This legal framework is designed to keep global trade flowing while balancing the security interests of coastal countries.
The Economic Stakes Are Enormous
Even the possibility of new restrictions has drawn close attention from energy companies, insurers, and shipping operators.
Higher insurance premiums, longer shipping routes, and increased security measures could raise transportation costs for oil, gas, and consumer goods. Countries heavily dependent on imported energy—including many in Asia and Europe—would likely feel the effects most quickly if disruptions became prolonged.
Beyond Shipping: A New Form of Strategic Leverage
The latest developments illustrate how maritime chokepoints have become instruments of geopolitical influence as much as transportation corridors.
Rather than relying solely on conventional military operations, governments and armed groups increasingly recognize that controlling—or even threatening—major shipping routes can influence diplomacy, energy markets, and international negotiations without direct confrontation. This reflects a broader shift in modern conflict, where economic pressure and strategic geography play a growing role alongside military power.
Looking Ahead
As tensions persist across the Middle East, the future of the Strait of Hormuz and the Bab el-Mandeb will remain closely watched by governments, businesses, and financial markets alike. While international law continues to support freedom of navigation, competing security claims and regional rivalries are testing long-standing maritime norms.
For the global economy, the stakes extend well beyond regional politics. The uninterrupted flow of ships through these narrow waterways remains essential to energy security, international trade, and economic stability, making any dispute over their governance a matter of worldwide concern.
