Iran IRGC Seizes Control, Blocks Strait
Analysis based on 6 articles · First reported Apr 19, 2026 · Last updated Apr 20, 2026
The consolidation of power by the Islamic Revolutionary Guard Corps in Iran and the subsequent blockade of the Strait of Hormuz will likely lead to increased oil prices and higher shipping costs, negatively impacting global energy markets and supply chains. The breakdown of diplomatic talks with the United States also signals prolonged instability in the region, deterring foreign investment in Iran and potentially leading to further sanctions.
The Islamic Revolutionary Guard Corps (IRGC) has effectively seized control of Iran's military and diplomatic negotiation teams, sidelining moderate figures like Abbas Araghchi and Mohammad Bagher Ghalibaf. IRGC Commander Ahmad Vahidi, with crucial support from Mohammad Bagher Zolghadr, has assumed leadership, leading to a hardline stance. This power shift is evidenced by increased maritime hostilities in the Strait of Hormuz, where Iran has targeted at least three vessels, leaving hundreds stranded and reinforcing a strict blockade. Iran has also bypassed scheduled peace negotiations with the United States, with internal dissent within the Iranian delegation, led by Mohammad Bagher Zolghadr's complaints, triggering a recall of negotiators. This development challenges Washington's assertions of a reformed Iranian regime and creates uncertainty for regional stability, with a fragile ceasefire deadline looming.
