Oil prices, including Brent Crude and West Texas Intermediate, plunged over 10% after Iran declared the Strait of Hormuz open, easing global supply fears. This positive development led to a surge in major stock indices like the S&P 500 and Nasdaq Composite, which built on record highs, reflecting hopes for an end to conflict and normalized supply chains.
Iran's Foreign Minister, Abbas Araghchi, announced that the Strait of Hormuz, a crucial waterway for global crude oil, would be 'completely open' for commercial vessels during the ongoing ceasefire. This declaration, made on X, led to a significant drop of over 10% in oil prices, with both Brent Crude and West Texas Intermediate falling below $90 per barrel. In response, major stock markets, including the S&P 500 and Nasdaq Composite, surged to new record highs, reflecting investor optimism about easing supply chain disruptions and potential peace. However, United States President Donald Trump stated that the US naval blockade of Iranian ports would remain in effect until a full peace deal is reached. The exact duration and scope of the ceasefire mentioned by Iran's Foreign Minister, whether it refers to a 10-day truce between Lebanon and Israel or an earlier two-week truce between Iran and the United States, remained unclear. French President Emmanuel Macron and UK Prime Minister Keir Starmer were also chairing a meeting to discuss sending a multinational force to ensure free trade in the Strait of Hormuz once the conflict concludes.
