Graphic: Tracking ship traffic through the Strait of Hormuz

Ship traffic through the Strait of Hormuz has remained nearly halted for several weeks amid ongoing conflict between Iran and the United States, significantly disrupting global oil and gas shipments. Despite a naval blockade imposed by the U.S. following failed peace talks and President Donald Trump’s demand to reopen the strait as a ceasefire condition, vessel movement has been minimal. Iran’s actions, including strikes on ships and demands for tolls, have effectively closed this critical maritime passage, through which about 20% of the world’s oil and natural gas once flowed. The situation escalated after a U.S.-Israeli attack on February 28, prompting Tehran to retaliate by targeting vessels and reportedly mining the strait. Iranian state media released a map from the Islamic Revolutionary Guard Corps Navy outlining designated safe routes for inbound and outbound traffic, though the effectiveness and safety of these corridors remain uncertain. The blockade and conflict have driven global energy prices higher, with U.S. gasoline prices surging over 30% in March, surpassing an average of $4 per gallon. Efforts to monitor the situation continue, with NBC News tracking daily ship movements through the strait, though the actual number of transiting vessels may be underreported due to GPS manipulation by some ships. The prolonged disruption of this vital shipping lane underscores the broader geopolitical tensions in the region and their far-reaching impact on global energy markets and trade security.
