Iran Escalates Hormuz Stance: Strait Closed to 'Enemy-Linked' Ships

The Strait of Hormuz, a critical global chokepoint for oil and gas transit, is currently at the center of escalating tensions following recent, contradictory statements and actions by Iranian authorities. Initially, on March 22, 2026, Iran's representative to the UN maritime agency, Ali Mousavi, was quoted in Iranian media reports, also carried by Reuters, stating that the Strait of Hormuz remains open to all shipping except vessels linked to 'Iran's enemies'. Mousavi indicated that ships not linked to 'Iran's enemies' (identified as the United States and Israel) could pass by coordinating security and safety arrangements with Tehran. This diplomatic statement emphasized Iran's commitment to maritime safety while underscoring its stance against hostile nations during what is described as an ongoing 'US-Israeli war on Iran'. However, just days later, the situation significantly escalated. On March 27, 2026, Iran's Islamic Revolutionary Guard Corps (IRGC) issued a more stringent declaration, announcing the outright closure of the Strait of Hormuz to maritime traffic for vessels traveling to or from ports associated with the 'Israeli-American alliance'. The IRGC explicitly stated that claims by the U.S. administration that the Strait of Hormuz is open are untrue, asserting that the strait is, in fact, closed to these specific entities. As part of this enforcement, the IRGC claimed to have turned back three container ships of different nationalities that attempted to transit the strait via authorized corridors after receiving warnings from IRGC naval forces. These attempts were reportedly made following what the IRGC described as 'lies' from U.S. President Donald Trump about the strait being open. Further clarifying Iran's nuanced but firm position, Iranian Foreign Minister Abbas Araqchi reiterated on March 26, 2026, that the Strait of Hormuz is 'only closed for our enemies' and that this is considered a 'legal right' given Iran is at war. Araqchi specified that Iran has permitted passage for vessels from 'friendly countries, including China, Russia, India, Iraq, and Pakistan'. This suggests a policy of selective control, where the strait is not universally closed but is actively restricted for vessels perceived as hostile or linked to adversaries. This policy has led to uncertainty for ship operators, with some choosing to avoid the waterway due to insecurity and insurers refusing coverage, even though Iran insists it remains open for others. The Strait of Hormuz is globally recognized as an indispensable chokepoint. Approximately one-fifth of the world's global oil and liquefied natural gas (LNG) supplies transit through this narrow waterway, connecting the Persian Gulf with the Gulf of Oman and the Arabian Sea. In 2025, nearly 20 million barrels per day (mb/d) of crude oil and oil products, representing around 25% of the world's seaborne oil trade, passed through the strait, with the majority destined for Asian markets, particularly China and India. Any significant disruption to traffic through the Strait of Hormuz would have profound consequences for global energy markets, leading to potential price surges and supply chain instability. For India, the situation in the Strait of Hormuz carries critical importance for its energy security and economic stability. More than two-thirds of India's crude oil imports and nearly half of its LNG imports flow through this vital maritime corridor. India's bilateral trade with the Gulf Cooperation Council (GCC) nations, amounting to around USD 178 billion, also heavily relies on uninterrupted movement through the strait. While India has been working towards diversifying its energy suppliers and expanding strategic petroleum reserves, a prolonged crisis would still significantly elevate oil prices, intensify inflationary pressures, and increase the country's import bill. The Indian Navy is reportedly on standby, and India-bound petroleum vessels continue to transit the strait under tight conditions, with naval support in place, reflecting India's proactive measures to safeguard its interests. The recent developments highlight Iran's strategy of leveraging its control over the strait as a 'calibrated instrument of wartime policy' amidst heightened regional conflicts and ultimatums from the U.S. President.
