Iran’s recent parliamentary approval to consider closing the Strait of Hormuz has raised alarms across global markets and geopolitical landscapes. This critical waterway, which serves as a passage for approximately 20% of the world’s oil supply, stands at the center of heightened tensions following a series of U.S. strikes on Iranian nuclear sites. Experts caution that while Tehran appears to be flexing its muscles, it stands to lose more than it gains from such a move.
The decision to potentially close the Strait now rests with Iran’s national security council. This development could lead to increased energy prices, ignite geopolitical conflicts, and alienate vital trade partners, particularly in the Gulf region. Vandana Hari, founder of Vanda Insights, expressed skepticism regarding the likelihood of a closure, noting, “The possibility remains absolutely minimalistic.” She emphasized that blocking the Strait could turn neighboring oil-rich nations against Iran, leading to serious ramifications for the country.
U.S. Energy Information Administration data shows Iran exported 1.5 million barrels of oil per day through the Strait in early 2025. Any disruption not only threatens Iran’s existing market relationships, particularly with China— its largest oil customer-but also jeopardizes its own oil production and export infrastructures. Andrew Bishop, a senior partner at Signum Global Advisors, supported this notion, explaining that agitating China’s interests would be counterproductive for Iran, especially given ongoing tensions with the U.S. and Israel, who have exhibited a robust military posture.
Concerns over the implications of a potential closure are further echoed by Clayton Seigle, an energy security expert at the Center for Strategic and International Studies. He pointed out that China, heavily reliant on oil from the Gulf, has a vested interest in maintaining stability and ensuring the safe transit of energy supplies through the Strait.
Currently, commercial shipping in the Strait remains uninterrupted, according to the Joint Maritime Information Center. Successful transits by U.S.-associated vessels in recent days offer a reassuring sign for immediate maritime operations. However, experts like Bishop warn that any Iranian disruptions would likely fall on a spectrum, not an absolute “all or nothing” scenario. Iran may attempt to manipulate oil flows to inflict economic pain on the U.S. without provoking a significant military response.
Patrick De Haan, head of petroleum analysis at GasBuddy, recently noted potential ramifications for U.S. gas prices, which could spike to between $3.35 and $3.50 a gallon soon. If a blockade were enacted, analysts predict Iran may resort to deploying small vessels for partial obstructions or even mining the Strait, complicating international shipping routes.
A note from S&P Global Commodity Insights indicated that such a closure would not only hinder Iranian exports but also significantly impact fossil fuel supplies from neighboring countries like Saudi Arabia and Qatar. This ripple effect could lead to the removal of over 17 billion barrels from global markets, affecting refineries, particularly in Asia, Europe, and North America. The Commonwealth Bank of Australia emphasized that bypassing the Strait would be nearly impossible, as existing pipeline capacities fall drastically short of current maritime transport levels.
With Goldman Sachs projecting an oil market risk premium increase of $12 due to these tensions, Brent crude could see prices soar to $110 per barrel if supply flows suffer substantial disruptions. As global energy markets keep a wary eye on these developments, the potential fallout underscores the intricate balance of geopolitics and energy security in the region.
