Iran Threatens Strait of Hormuz Closure
Analysis based on 25 articles · First reported Apr 18, 2026 · Last updated Apr 20, 2026
The standoff in the Strait of Hormuz, a critical oil chokepoint, threatens to deepen the global energy crisis, leading to potential spikes in oil prices and increased volatility in energy markets. The continued blockades by the United States and Iran also create uncertainty for international shipping and trade, potentially impacting global supply chains and increasing insurance costs for vessels transiting the region.
Iran has doubled down on its threat to restrict ships passing through the Strait of Hormuz in retaliation for the United States's blockade of Iranian ports. This escalation comes as a ceasefire between the United States and Iran is set to expire, with mediators from Pakistan scrambling to arrange further negotiations. Iranian parliamentary Speaker Mohammad Bagher Ghalibaf stated that it is 'impossible for others to pass through the Strait of Hormuz while we cannot,' emphasizing Iran's resolve. The situation intensified after Iran's Revolutionary Guard gunboats fired on two India-flagged merchant ships, forcing them to turn back. The United States, under President Donald Trump, insists its blockade will remain in full force until a deal is reached, while Iran's Deputy Foreign Minister Saeed Khatibzadeh has accused the United States of risking the global economy. The potential closure of the Strait of Hormuz, through which one-fifth of the world's oil passes, threatens to exacerbate the global energy crisis and reignite a war that has already claimed thousands of lives in Iran, Lebanon, and Israel.
