Iran Reopens Strait of Hormuz to Asian Shipping Following Agreements

Iran has granted a conditional two-week window for shipping transit through the Strait of Hormuz following an announcement of a double-sided ceasefire by US President Donald Trump. Iranian Foreign Minister Abbas Araghchi confirmed the development on April 7, 2026, though he stated that passage would only be possible via coordination with Iran’s Armed Forces and with due consideration of technical limitations.

The conditional reopening follows a period of extreme volatility in the world’s most critical energy artery. Prior to the conflict, the waterway operated under a traffic system that allowed more than 100 ships per day to pass freely through Omani and Iranian waters. However, Tehran effectively closed the strait shortly after it was attacked by the United States and Israel on February 28, 2026.

Global Market Volatility

The announcement of the limited reopening triggered a sharp reaction across global financial sectors on April 7, 2026. US crude oil, which had reached a peak of $117 per barrel earlier that day, crashed by more than 15% to settle at $95 per barrel. Despite this drop, oil prices remain up 70% for the year, a reflection of the disruptions caused by the halt of marine traffic since March.

Wall Street responded to the potential de-escalation with a relief rally. Dow futures increased by 1,000 points, while Nasdaq 100 and S&P 500 futures rose by 2.6% and 2% respectively. In Asia, the Nikkei was expected to open nearly 3% higher following the news.

The Permissions-Based Transit System

During the closure, Iran established what Lloyd’s List Intelligence described as a de facto toll booth regime. This permissions-based system, operated by the Islamic Revolutionary Guard Corps (IRGC), replaced international maritime law with direct diplomacy. Vessels from countries deemed friendly by Tehran were escorted through specific narrow corridors.

One route was established as a northern corridor near Larak island. A second, southern corridor near the Omani coastline became operational more recently. Windward Maritime Intelligence tracked 11 transits across both routes on Sunday, April 6, 2026, consisting of eight outbound and three inbound vessels.

Foreign Minister Abbas Araghchi has publicly identified the nations considered friendly enough to secure passage through this system, including China, Russia, India, Iraq, and Pakistan. The Iranian Embassy in Malaysia announced on Monday, April 7, 2026, that the first of seven stranded Malaysian ships had safely passed through the waterway, stating that the Islamic Republic of Iran does not forget his friends.

Conflict Escalation and Diplomatic Pressure

The closure of the strait was a direct response to the February 28 attacks. The IRGC declared the waterway closed to the US, Israel, and nations supporting those attacks. The impact on global energy flows was immediate; according to the maritime tracking platform Kpler, commodity traffic through the strait fell by 95% at the start of the conflict. Between March 1 and March 25, only 116 total crossings were recorded, compared to the pre-war average of approximately 135 vessels per day.

The US administration has utilized a combination of threats and diplomatic pressure to force the reopening. President Donald Trump threatened to obliterate Iran’s energy infrastructure if the strait remained closed. On March 26, 2026, Secretary of State Marco Rubio stated that the strait could be open tomorrow if Iran stops threatening global shipping.

While the US has attempted to portray the energy price spikes as a temporary issue, noting the US is less dependent on Middle Eastern oil than its allies, Trump has also suggested that the US could potentially charge tolls for passage through the strait.

Despite the two-week window announced on April 7, global markets remain cautious. The mention of technical limitations by Foreign Minister Araghchi—a factor that did not exist before the war—has led traders to question whether Tehran intends to maintain strict control or continue imposing the transit fees it established during the hostilities.
