Iran Reopens Strait of Hormuz Following U.S. Ceasefire Deal

The Government of Iran announced the reopening of the Strait of Hormuz to commercial vessels on April 17, 2026, following a 10-day ceasefire between Israel and Lebanon and a broader truce with the United States. The reopening follows a 47-day blockade that began in late February after joint U.S.-Israeli airstrikes hit Iranian territory. This closure removed approximately 10 million barrels of oil per day from the market, driving Brent crude above $100 per barrel and leaving Europe with only six weeks of jet fuel reserves.

While Iranian Foreign Minister Abbas Araghchi declared the waterway "completely open," the Islamic Revolutionary Guard Corps imposed strict transit conditions, requiring ships to use Iranian-approved routes and obtain authorization. Simultaneously, Donald Trump maintained a U.S. Navy blockade of Iranian ports, asserting it would remain in force until a final peace deal is completed. Trump expressed optimism that a comprehensive agreement to end the war and resolve Iran's nuclear ambitions would be reached soon.

The announcement triggered an immediate global market reaction, with oil prices plummeting over 10% and U.S. stock markets hitting record highs. In Australia, retail petrol prices dropped below $2.10 per litre, though officials warn that infrastructure damage in the Persian Gulf may prevent a full price recovery until 2027. International leaders, including Australian Prime Minister Anthony Albanese, welcomed the move but described it as a "fragile arrangement," calling for a permanent, toll-free reopening of the strategic chokepoint.
