Iran has reclosed the Strait of Hormuz, a critical waterway for global oil supplies, in retaliation to the United States' ongoing blockade of Iranian ports. The Islamic Revolutionary Guard Corps (IRGC) announced on Saturday that control of the strait had 'returned to its previous state,' with Iranian gunboats reportedly firing at a merchant vessel attempting to cross.The strait's closure comes after a brief reopening, during which over a dozen commercial ships passed through. This development has cast doubt on US President Donald Trump's optimism about a potential peace deal to end the US-Israel war on Iran, which Trump claimed was 'very close.'The IRGC statement emphasized that the blockade represented 'acts of piracy and maritime theft,' and warned that the strait would remain under strict control until the US restores full freedom of navigation for Iranian vessels. Oil prices have been impacted, with at least eight oil and gas tankers crossing the strait by 10:30 GMT, while several others turned back.The situation has created uncertainty for maritime shipping, with specialist John-Paul Rodrigue noting that contradictory information from all parties has deterred many vessels from crossing. Al Jazeera's Tohid Asadi reported from Tehran that Iran seeks a comprehensive end to the regional war, including security assurances, sanctions relief, and a resolution to its nuclear dossier.

Oil prices have plummeted to their lowest point in weeks after Iran said the Strait of Hormuz was open for passage during a ceasefire in Lebanon. The international benchmark, Brent crude, fell more than 9 percent to $90.38 a barrel on Friday, taking it below $91 for the first time since March 10.Iranian Foreign Minister Abbas Araghchi said the strait was “completely open” and would remain so for the duration of the 10-day ceasefire between Israel and Lebanon, which took effect on Friday. US President Donald Trump hailed Tehran’s announcement, declaring the waterway “ready for business and full passage.”However, on Saturday, Iran rowed back on its decision to reopen the Strait of Hormuz, warning that it would continue to block transit through the key waterway as long as the US blockade of Iranian ports remained in effect. Trump said the blockade “will remain in full force” until Tehran reaches a deal with the US, including on its nuclear programme.Roughly one-fifth of the world’s oil passes through Hormuz and further limits would squeeze already constrained supply, driving prices higher once again. Amid the escalation, Pakistani officials say they are trying for more talks between the US and Iran ahead of the April 22 ceasefire deadline.Meanwhile, ship tracking data displayed a significant uptick in vessels crossing the strait on Saturday, with an analyst at maritime intelligence firm Windward saying it was the busiest since the Strait of Hormuz was effectively closed at the beginning of the war.

In a recent declaration, Iranian officials emphasized that the Strait of Hormuz serves as the nation’s most effective deterrent against external pressure. The statement reflects Tehran’s reliance on the narrow maritime corridor, which channels a substantial portion of the world’s oil shipments, as a cornerstone of its strategic posture.By positioning the strait as a pivotal security asset, Iran signals that any threat to its interests in the region would encounter a robust geographic counterweight. This stance reinforces the broader geopolitical narrative that Iran continues to leverage its location to shape regional dynamics and safeguard its national interests.

French President Emmanuel Macron has publicly demanded security assurances from Tehran after Iran announced the reopening of the Strait of Hormuz. The strategic waterway, through which a significant share of the world’s oil passes, has long been a focal point of geopolitical tension. Macron’s request underscores France’s concern for the safety of maritime traffic and the stability of global energy markets. While details of the assurances sought were not disclosed, the French leader emphasized the need for clear guarantees that the reopening will not jeopardize navigation or exacerbate regional volatility.

Speaker of Iran’s parliament Mohammad Bagher Ghalibaf publicly rejected seven recent statements by U.S. President Donald Trump concerning Iran, labeling them false. He warned that the Strait of Hormuz – a vital global shipping lane – will not remain open should the United States continue its blockade of Iranian ports, underscoring the potential for heightened regional disruption.In contrast, Trump told the AFP news agency that there are no "sticking points" left in the pursuit of a deal with Tehran, and he shared a series of optimistic messages on social media about apparent agreements with Iran. The divergent narratives reflect deepening mistrust as peace talks progress, with significant implications for maritime traffic and broader U.S.-Iran diplomatic efforts.

Iranian authorities announced a swift reversal of the Strait of Hormuz’s reopening, reinstating tight military oversight after Washington declared it would maintain the blockade on Iranian ports.IRGC vessels engaged a tanker attempting to transit the waterway on Saturday, and a separate Indian‑flagged crude carrier was also reported to have come under fire, according to a UK maritime agency and Reuters.The Khatam al‑Anbiya joint military command stated that the strait has returned to its "previous status" and is now under "strict management and control by the armed forces". The restrictions will stay in place unless the United States guarantees full freedom of navigation for vessels traveling to and from Iran, a condition reiterated by Deputy Foreign Minister Saeed Khatibzadeh and the IRGC navy command.Speaking at a Turkish diplomatic forum in Antalya, Khatibzadeh warned that the U.S. cannot impose a "siege" on Iran while Tehran seeks to ensure safe passage through the strategic chokepoint.On the social platform X, the IRGC navy warned that any perceived breach of U.S. commitments would elicit a "appropriate response" and that the strait’s status would remain unchanged as long as Iranian shipping faces threats.Iran initially closed the strait on 4 March following U.S.–Israeli airstrikes, reopening it only after a 10‑day ceasefire between Israel and Lebanon was brokered. The latest U‑turn follows President Donald Trump’s declaration that the U.S. blockade will remain in force until a permanent peace agreement with Tehran is reached, and he hinted that the temporary Pakistan‑mediated ceasefire may not be extended.The UK’s Maritime Trade Operations Centre reported that a tanker was approached and fired upon by two IRGC gunboats about 20 nautical miles northeast of Oman. The vessel’s captain confirmed that no radio warning was given, but the crew emerged unharmed and authorities are investigating.Despite the brief reopening, maritime tracking showed that only eight oil and gas tankers managed to pass through the strait before Iran’s reversal.Approximately 20% of global oil and liquefied natural gas transits the Strait of Hormuz, making it a focal point of the broader U.S.–Israeli‑Iran conflict. Its closure has already contributed to rising energy prices worldwide.Regional diplomats remain cautiously optimistic: Egypt’s foreign minister Badr Abdelatty expressed hope for a deal "in the coming days," noting that the prolonged conflict harms not only the Middle East but the entire world.

Iran's Foreign Minister Abbas Araghchi announced on Friday that the Strait of Hormuz is open to all commercial vessels during a 10-day Lebanon ceasefire accord. This led to a fall in oil and other commodity prices, while stock markets rose. However, shipping companies are seeking clarifications on safety and security before transiting the strait. The Norwegian Shipowners' Association and shipping association BIMCO have expressed concerns about the presence of mines and Iranian conditions for transit. The International Maritime Organization is verifying Iran's announcement to ensure compliance with freedom of navigation for all merchant vessels and secure passage. Transit would be restricted to lanes deemed safe by Iran, and military vessels are still prohibited. Shipping companies such as Hapag-Lloyd and Maersk are closely monitoring the situation and assessing risks before making a decision. The US Navy has also issued an advisory warning of the threat posed by mines in parts of the strait. The Strait of Hormuz is one of the world's most important maritime chokepoints, and any disruption can have significant impacts on global trade and economy.

Iran’s foreign minister Abbas Araghchi announced on Friday that the Strait of Hormuz is "completely open" for commercial traffic, aligning the decision with the newly‑instated ceasefire between Israel and Lebanon. President Donald Trump echoed the statement on social media, insisting the waterway is ready for business but also stressing that the U.S. naval blockade on Iranian ports will remain in full force until a comprehensive agreement is reached. In Paris, France and the United Kingdom convened a summit of roughly 40 countries to discuss a coordinated effort to restore freedom of navigation in the strait once the broader U.S.–Iran conflict subsides. The strait channels about 20 % of the world’s daily crude oil flow; its blockage had previously pushed fuel prices upward worldwide. The latest announcement prompted an immediate plunge in oil prices, offering a brief reprieve for markets. United States: Trump posted on Truth Social that the strait is "completely open and ready for business," yet reiterated that the blockade will stay in effect "until our transaction with Iran is 100 % complete." He later told AFP the deal to end the war on Iran is "close" with "no sticking points" remaining. Iran: Araghchi shared the opening on X, tying it to the 10‑day ceasefire. However, later state media quoted a senior IRGC official saying only non‑military vessels would be permitted, subject to IRGC Navy approval, highlighting internal ambiguity. United Kingdom: Prime Minister Keir Starmer co‑hosted the Paris summit with French President Emmanuel Macron, welcoming the reopening but urging that any solution be "lasting and workable." He pledged a "strictly peaceful and defensive" multinational mission to protect navigation when conditions allow. France: Macron called for an "immediate and unconditional" reopening by all parties and warned against any attempts to "privatise" the strait or impose tolls. His office outlined potential coalition roles, including intelligence, mine‑clearing, military escorts, and communication with coastal states. Germany: Chancellor Friedrich Merz offered German mine‑clearance and intelligence support, pending parliamentary approval and a UN Security Council mandate. He expressed a desire for U.S. participation, a request Trump publicly dismissed. Finland: President Alexander Stubb, attending the summit, praised Iran’s announcement but emphasized that durable solutions require diplomatic effort. United Nations: Secretary‑General António Guterres welcomed the opening as "a step in the right direction," while the International Maritime Organization began verifying compliance with freedom‑of‑navigation standards. Shipping industry: The Norwegian Shipowners’ Association, representing 130 firms and 1,500 vessels, called the development welcome but said practical details—such as mine presence and Iranian conditions—must be clarified. Germany’s Hapag‑Lloyd and Denmark’s Maersk both indicated they are reassessing risks but remain cautious about immediate transits. Markets: Analysts noted the announcement’s swift impact on oil markets. "This is the biggest development so far during the ceasefire and gives hope that the war will end soon," said Kathleen Brooks, research director at XTB.

The United Nations refugee agency has revealed that nearly 900 Rohingya refugees were reported dead or missing in the Bay of Bengal and the Andaman Sea in 2025. This was the deadliest year on record for maritime movements in South and South East Asia.Thousands of people continue to make the dangerous journeys in 2026, with the UNHCR describing the area as an “unmarked graveyard for thousands of desperate Rohingya refugees”. Over the last decade, some 5,000 Rohingya are thought to have drowned at sea.Hundreds of thousands of Rohingya refugees began fleeing Myanmar in 2017 amid an ethnic cleansing campaign. They largely settled in refugee camps in Bangladesh, which continues to give refuge to those fleeing today. However, humanitarian aid in the country has been reduced due to funding shortfalls, and there is limited access to education and opportunities in the camps, prompting people to attempt the dangerous sea crossings.More than 2,800 Rohingya have made the sea journeys this year, with the majority leaving from Cox’s Bazar in Bangladesh or Rakhine State in Myanmar in the hope of reaching Malaysia or Indonesia. The UNHCR hopes that highlighting the record death toll will make people aware of “what the Rohingyas are going through inside Myanmar and in the refugee camps and in the wider region” and prompt solutions to avoid another record toll in 2026.
