Iran took a dramatic diplomatic turn on March 26 by announcing that commercial vessels from China, Russia, India, Iraq, and Pakistan would be granted safe passage through the Strait of Hormuz, while Western-flagged ships remain effectively blocked. The move has weaponized the world's most critical energy chokepoint as a tool of geopolitical leverage, creating a two-tier system for global oil transit.
The selective transit policy has profound implications for global energy markets. Ships from Malaysia and Thailand were subsequently added to the approved list, expanding the coalition of nations receiving preferential treatment. Collectively, these countries represent roughly 3.5 billion people and a growing share of global oil demand, giving Iran significant diplomatic leverage.
Western Allies Face Supply Squeeze
European nations and Japan have been hardest hit by the selective blockade, as their oil imports from Gulf producers have been cut to near zero since the crisis began on February 28. The EU has been forced to rely almost entirely on non-Gulf sources including Norway, West Africa, and the Americas, but logistical bottlenecks and limited spare capacity have driven European gas-oil prices to record premiums over global benchmarks.
China's strategic petroleum reserve, estimated to cover 100 to 120 days of normal consumption, provides a significant buffer that most Western importing nations lack. Beijing's refusal to support the U.S. military campaign to reopen the strait—flatly rejecting Trump's request that China send warships—has created deep fissures in what had been a tentative period of bilateral engagement.
New Toll Demand Emerges
In a further escalation, Iran has demanded that nations wishing to transit the strait pay a toll, potentially generating billions in revenue. CNN reported that this demand has become a central element of peace negotiations, with Iran seeking to establish a permanent revenue stream from the waterway it argues is within its sovereign territorial waters.
The crisis has accelerated discussions about alternative energy transit routes, including the expansion of the East-West Pipeline across Saudi Arabia and new pipeline capacity through Turkey. However, these alternatives would take years to build, leaving the global economy vulnerable to continued disruption in the near term.
