Hormuz blockade cuts cargo traffic 52% as US charges 20% fee and Iran closes strait to shipping.
The Strait of Hormuz faces severe disruption as competing blockades reduce vessel transits by 52%, with the US and Iran implementing overlapping maritime restrictions. Iran has declared the Strait closed to international shipping while the US maintains a naval blockade of Iranian ports, creating dual constraints on commerce through the strategic waterway carrying approximately one-third of globally traded oil.
President Trump has announced a 20% fee on all cargo transiting the Strait, introducing a new economic mechanism for controlling passage. Iran has responded by attacking commercial vessels in the waterway, escalating the conflict from military operations into direct civilian shipping disruption.
The dramatic traffic decline reflects market uncertainty about sustained maritime access, with traders and shipping operators reassessing route viability. Oil prices have increased 3-3.75% in response to the supply disruption concerns. The competing blockade declarations and merchant vessel attacks demonstrate how the military confrontation has evolved from air and missile operations into contested control over one of the world's most critical commercial chokepoints.
