The Trump administration declared an expansion of secondary sanctions on entities and countries maintaining business ties with Iran, increasing economic pressure on Tehran as the conflict enters its sixth month. Treasury Secretary Scott Bessent, during a press conference, introduced what he termed an “economic D-Day” to urge countries to sever connections with Iran or face key companies and entities being isolated from the dollar-based financial system. “We are initiating an economic offensive against Iran’s global financial links. Our goal is to cut off every economic support sustaining this oppressive regime until Tehran stands isolated,” stated Bessent.
The U.S. Treasury Department revealed it has identified the networks, facilitators, and financial channels Iran utilizes to smuggle oil and evade sanctions, pledging to collaborate with U.S. partners to target any sources of Iran’s “illicit revenue.” Sanctions have been imposed on five sectors – digital assets, technology, gold, aviation, and shipping – that Iran exploits to bolster its economy, with nearly 60 entities, individuals, and vessels facing sanctions.
China has historically been the largest purchaser of Iranian oil, and efforts have intensified to restrict Chinese transactions without targeting major Chinese banks that may facilitate such trade. Iran had warned of potential military retaliation and further reductions in oil exports from the Gulf in response to U.S. economic actions. Iranian Finance and Economic Affairs Minister Ali Madanizadeh affirmed readiness for U.S. sanctions, stating, “Our defense is no longer purely defensive; the enemies should anticipate a counterattack.”
Brig-Gen. Hossein Mohebbi of Iran’s Islamic Revolutionary Guard Corps (IRGC) vowed severe repercussions for U.S. vital interests and energy chokepoints if Iran’s infrastructure is endangered. The ongoing conflict has elevated energy prices globally and disrupted oil and raw material shipments through the Strait of Hormuz, maintaining heightened energy prices. President Trump’s approval ratings have declined, with only 33% of Americans approving of his performance in the latest Reuters/Ipsos poll. Trump justifies the economic costs as necessary to prevent Iran from acquiring nuclear weapons.
The U.S. has enforced sanctions against Iran for years, primarily targeting its oil revenues, aviation sector, cryptocurrency activities, weapons procurement, and IRGC-affiliated businesses. Designated entities are barred from the dollar-based financial system, yet Iran has managed to establish new front companies and vessel registrations to evade these restrictions.
