The Trump administration announced on Monday an extension of secondary sanctions that can be enforced on entities and countries doing business with Iran, escalating economic pressure on Tehran as the conflict approaches its six-month mark. Treasury Secretary Scott Bessent, during a press briefing, revealed a new economic initiative termed as an “economic D-Day” to signal countries to sever ties with Iran or face the risk of key companies and entities being isolated from the dollar-based financial system.
“We are initiating a comprehensive economic campaign against Iran’s global financial connections. Our goal is to cut off every economic support system that sustains this oppressive regime until Tehran stands isolated,” stated Bessent. The U.S. Treasury Department disclosed that it had identified the networks, facilitators, and financial channels utilized by Iran for oil smuggling and sanctions evasion. The U.S. will collaborate with partners to target any sources of Iran’s illicit revenue.
The Treasury Department has taken action against five key sectors – digital assets, technology, gold, aviation, and shipping – exploited by the Iranian government to bolster its economy. Sanctions have been imposed on almost 60 entities, individuals, and vessels. China, a major buyer of Iranian oil, has been a focus of U.S. efforts to restrict its purchases without yet targeting significant Chinese banks potentially facilitating the trade.
Iran, prior to the announcement, issued warnings of potential military retaliation and further reduction in Gulf oil exports in response to U.S. economic measures. Iranian Finance and Economic Affairs Minister Ali Madanizadeh expressed readiness for the U.S. sanctions, stating, “We are fully prepared.” Additionally, Brig-Gen. Hossein Mohebbi from Iran’s Islamic Revolutionary Guard Corps (IRGC) threatened severe repercussions to U.S. interests and energy chokepoints if Iran’s infrastructure faced threats.
As the U.S.-Iran conflict nears six months, global energy prices have surged. Though combat has eased, diplomatic efforts to resolve the crisis have stalled, and shipping through the Strait of Hormuz remains disrupted, causing continued high energy prices. Trump’s approval ratings have declined, with only 33% of Americans in the latest Reuters/Ipsos poll supporting his performance. The President justifies the economic costs as necessary to prevent Iran from acquiring nuclear weapons.
The U.S. has upheld sanctions against Iran for years, primarily targeting its oil revenues, aviation sector, cryptocurrency activities, weapons procurement, and business enterprises linked to the IRGC. These sanctions restrict designated entities from the dollar-based financial system, yet Iran has managed to establish new front companies and vessel registrations to evade these measures.
