The US–Iran maritime standoff in the Strait of Hormuz has intensified, causing significant global economic volatility. While President Trump previously claimed the strait was navigable, a diplomatic impasse has stalled reopening efforts. Defense Secretary Pete Hegseth stated the US Navy could maintain a naval blockade “indefinitely” through ship rotation, with Trump characterizing the blockade as a “steel wall.” CENTCOM reports that the blockade has expanded, with American forces having redirected 68 commercial vessels, disabled three, and boarded two others. Maritime traffic has since seen a sharp decline, reaching historic lows. Data from Kpler indicates that commodity ship traffic has plummeted from a pre-conflict average of 95 vessels per day to approximately 15 vessels per day as of August 2026. On August 24, only two transport vessels were detected crossing the strait, the lowest level since early May. Approximately 6,000 sailors and 500 ships remain stranded in the Gulf. Iran has blacklisted 45 tankers, leading some Indian refineries and international energy companies to avoid those vessels to mitigate risks of seizure or fines. Many vessels now navigate with Automatic Identification Systems (AIS) deactivated to avoid traceability. ~~Global~~ Discrepancies have emerged regarding oil ~~supplies face severe pressure.
