Iran's Islamic Revolution Guards Corps (IRGC) announced on April 20, 2026, that the strategic Strait of Hormuz will remain closed until the United States ends its naval blockade against Iranian ports and vessels. The decision, effective since Saturday evening, follows Washington's alleged violation of a two-week ceasefire agreement that began on April 8.
In a statement published by Sepah News, the IRGC accused the U.S. of failing to honor commitments under the temporary truce, which aimed to de-escalate tensions in the Persian Gulf. The strait, a critical chokepoint for global oil shipments, sees 21% of the world's petroleum consumption pass through its waters annually.
Analysts warn the closure could disrupt energy markets already strained by recent geopolitical shifts. Brent crude prices surged 4.2% in early trading this week, reflecting investor concerns. Regional stability remains fragile, with the DPRK issuing a statement supporting Iran's 'right to defend its maritime interests.'
Business leaders and governments worldwide are urging diplomatic resolution, while the U.S. Navy's Fifth Fleet continues patrols near Oman's territorial waters. The standoff highlights growing friction over maritime security frameworks in the Middle East, with implications for global supply chains and energy-dependent economies across Asia.
