Major Carriers Continue Strait of Hormuz Transit Amid Iran Closure Threats

Following U.S. strikes on Iranian nuclear sites, tensions have escalated around the Strait of Hormuz, a vital waterway that channels roughly 20% of the world's seaborne oil trade. Iran's parliament has approved a potential closure of the Strait, a move that would require Supreme National Security Council approval and could severely disrupt global oil supplies, sending prices soaring and threatening economic stability worldwide. In response, major shipping companies including Japan’s NYK Line and Mitsui O.S.K. Lines have directed their vessels to minimize time spent in the Persian Gulf and pass quickly through the Strait, while maintaining operations and closely monitoring the situation from safety support centers in Tokyo. Other global carriers like Maersk, Hapag-Lloyd, and CMA CGM continue transits but have adjusted routes and suspended some services, especially to ports like Haifa, citing security concerns. The U.S. has warned Iran against closing the Strait, calling such action "economic suicide" and promising a severe response, highlighting the strategic importance of the waterway for global energy markets and international trade. Despite the threats and increased military activity, satellite images confirm ongoing tanker movements through the Strait, with shipping companies balancing operational continuity against escalating risks.
