The Strait of Hormuz is largely closed to commercial shipping as of late March 2026, despite Iran's claims that it remains open to all vessels except those linked to its "enemies." This development follows escalating tensions in the Middle East, which began on February 28, 2026, after joint military strikes by the United States and Israel on Iran. Iran's Islamic Revolutionary Guard Corps (IRGC) has threatened a complete shutdown of the vital waterway if the US targets Iranian energy facilities. Global oil prices have surged, and international bodies are calling for immediate de-escalation.[kpler+5]
Iran Tightens Grip on Shipping
Iran's representative to the International Maritime Organization (IMO), Ali Mousavi, stated on Sunday, March 22, 2026, that the Strait of Hormuz is open to all shipping except vessels connected to "Iran's enemies," a term widely understood to refer to the United States and Israel.Mousavi clarified that ships not linked to these "enemies" can pass through the Strait if they coordinate security and safety arrangements with Tehran.He added that diplomacy remains Iran's priority, but a full stop to aggression and mutual trust are more important.Mousavi pointed to US and Israeli actions as the root of the current situation.[hindustantimes+18]
The IRGC issued a stark warning on March 23, 2026, stating that the Strait of Hormuz would be "completely closed" and would not reopen until any Iranian power plants destroyed by US threats are rebuilt.This came after US President Donald Trump issued a 48-hour ultimatum, threatening to "obliterate" Iranian power plants if the Strait was not fully opened.Iranian Parliament Speaker Mohammad Baqer Qalibaf reinforced this, saying that critical infrastructure and energy facilities in the Middle East could be "irreversibly destroyed" if Iranian power plants are attacked.[news24online+9]
The Strait, a narrow passage connecting the Persian Gulf with the Gulf of Oman, carries approximately 20% of the world's daily oil supply and significant volumes of liquefied natural gas (LNG).Data from MarineTraffic on Thursday, March 20, 2026, showed transit activity through the Strait had slowed to a near standstill.Around 20,000 seafarers and 2,000 vessels are currently trapped in the Gulf, according to the IMO.Reports also indicate Iran is charging transit fees, with at least one tanker reportedly paying $2 million to pass.[kpler+10]
Japan Considers Minesweeping Role
Amid these heightened tensions, Japan is considering deploying its Self-Defense Forces for minesweeping operations in the Strait of Hormuz.Japanese Foreign Minister Toshimitsu Motegi stated on Sunday, March 22, 2026, that this move is purely hypothetical and would only occur if a ceasefire is reached in the ongoing conflict.Motegi emphasized that if a ceasefire were established and naval mines created an obstacle, then minesweeping would be something to consider.[middleeasteye+20]
Japan's interest in securing the waterway is significant because about 90% of its crude oil imports pass through the Strait of Hormuz.Japan's post-war pacifist constitution limits overseas military action, but 2015 security legislation allows its Self-Defense Forces to operate abroad under specific conditions, particularly when threats affect Japan's survival.Japan's minesweeping technology is considered among the best globally.However, Tokyo has no immediate plans to negotiate separate arrangements for Japanese vessels, prioritizing conditions for universal navigation.[hindustantimes+15]
Global Economic Fallout and International Response
The effective closure of the Strait has triggered a severe global energy crisis. Brent crude oil prices surpassed $100 per barrel on March 8, 2026, for the first time in four years, reaching a peak of $126 per barrel.European natural gas prices also jumped by 60% since the conflict began.This disruption affects about 20% of the world's daily oil supply and significant volumes of liquefied natural gas.Major shipping firms have suspended operations, and insurance premiums have reached multi-year highs, making transit economically unviable for most operators.[en+11]
The crisis has led to physical supply disruptions. Early reports indicate curtailment of southern Iraqi oil production, with output dropping by 70% from 4.3 million barrels per day to 1.3 million barrels per day as of March 8.Saudi Arabia also reduced its oil production by 20%, from 10 million barrels per day to 8 million, after the shutdown of two offshore fields.As of March 12, 2026, Iran had carried out 21 confirmed attacks on merchant ships.[en+2]
More than 20 countries, including Japan, the UAE, UK, France, and Germany, issued a joint statement condemning Iran's attacks on commercial vessels and infrastructure around the Strait of Hormuz.They called for an immediate end to threats, mine-laying, and drone and missile attacks, urging Iran to comply with UN Security Council Resolution 2817.The statement emphasized that freedom of navigation is a fundamental principle of international law, including under the UN Convention on the Law of the Sea (UNCLOS), which governs the Strait of Hormuz as an international waterway.The International Energy Agency has authorized a coordinated release of strategic petroleum reserves to stabilize markets.[time+9]
The ongoing situation in the Strait of Hormuz represents a critical challenge to global energy security and international maritime law. The world watches for a resolution to the conflict and the potential for a return to safe passage through this vital chokepoint.
