US Intensifies Economic Offensive Against Iran Amid Strait of Hormuz Conflict

The United States has launched what Treasury Secretary Scott Bessent calls an economic D Day against Iran, marking the largest financial offensive ever deployed against an enemy. This escalation comes as the US demands that other nations sever ties with Tehran or face economic exclusion. In response, Iran has threatened to block all oil shipments through the Strait of Hormuz, a critical maritime route for global energy. While Iran claims the strait remains closed and requires authorization for transit, the US military reports that it has successfully escorted approximately 1,000 ships through the strait since May. These vessels reportedly travel at night without transponders along the coast of Oman to avoid Iranian drones and missiles.

Oil flow through the region has decreased significantly since the conflict began on February 28. Data from Kpler indicates that Iranian exports through the strait fell from two million barrels per day before the war to roughly 400,000 by mid August. Meanwhile, China remains a primary buyer of Iranian oil, though volumes have fluctuated. Kpler data shows Chinese intake dropped to 534,000 barrels per day in August, down from higher levels earlier in the year. The US has targeted smaller Chinese refiners and shipping firms with sanctions to curb this trade, though some reports suggest these measures have had limited impact on overall flows.

Diplomatic efforts continue as Oman's Foreign Minister, Badr al Busaidi, is traveling to Iran to discuss the regulation of ship transit and regional security. Iran maintains that a full reopening of the strait depends on the US lifting its blockade of Iranian ports. President Donald Trump has asserted that Iran is collapsing and that the US maintains total control over the strait. Conversely, Iranian officials argue that the intensity of the US financial offensive proves that Washington has not yet achieved its military and political goals.
