Overview
- Treasury Secretary Scott Bessent framed the campaign as an "economic D‑Day" in a Financial Times op‑ed and said the administration will marshal its full authorities to isolate Iran economically.
- The plan focuses on penalizing third‑party enablers of Iranian trade, naming purchasers of oil, transporters, exchange houses, free‑trade zones and ship registries as likely targets of new measures.
- The White House is moving from public signaling to imminent implementation while leaving many enforcement details undisclosed; the Treasury already sanctioned more than 100 vessels linked to Iran’s covert "shadow fleet" in July.
- Iran has warned it will treat participation in the U.S. campaign as an act of war and threatened to disrupt oil exports through the Strait of Hormuz, raising the risk of wider regional confrontation.
- Major partners are weighing responses: China has urged restraint and said it will protect its interests, Pakistan has offered mediation, and Gulf trade and finance actors face legal and commercial pressure that could raise global fuel prices and strain banks, insurers and shipping firms.
