On Monday, the administration of U.S. President Donald Trump revealed an enhancement of secondary sanctions that can be imposed on nations and entities maintaining commercial relations with Iran, dramatically increasing economic pressure on Tehran as the conflict approaches its six-month milestone.
During a press briefing, Treasury Secretary Scott Bessent introduced what he referred to as an “economic D-Day,” designed to serve as a final warning for nations to cut business links with Iran or face repercussions that could exclude significant companies and entities from the dollar-dominated financial system.
Bessent stated, “We are initiating an economic offensive against Iran’s financial networks worldwide. Our goal is to eliminate every economic lifeline that supports this oppressive regime until Tehran is isolated.”
The U.S. Treasury Department announced that it has identified the networks, facilitators, and financial routes Iran utilizes to smuggle oil and avoid sanctions, asserting that Washington will collaborate with U.S. allies to target any source of Iran’s “illicit revenue.”
According to the department, it has made determinations against five sectors — digital currencies, technology, gold, aviation, and shipping — that the Iranian government exploits to sustain its economy. Additionally, the Treasury has enacted sanctions against nearly 60 entities, individuals, and vessels.
China has been the leading purchaser of Iranian oil for several years. Washington has escalated efforts to restrict Chinese imports but has yet to designate larger Chinese banks that might be enabling the trade.
‘Wait for an attack,’ Iran warns
Prior to the announcement, Iran issued threats of a potential military response and a further decrease in oil exports from the Gulf in reaction to any U.S. economic actions.
Following the announcement, Iranian Finance and Economic Affairs Minister Ali Madanizadeh remarked, “We are completely prepared for the U.S. sanctions.”
“Naturally, our adversaries plan to launch an economic terrorist offensive against us, but we possess our own resources and understand how to navigate the situation. Our defense has evolved from being purely defensive; the adversaries should anticipate an aggressive response,” Madanizadeh told state television.
Brig-Gen. Hossein Mohebbi, a spokesperson for Iran’s Islamic Revolutionary Guard Corps (IRGC), declared that significant retaliatory actions would be taken against U.S. critical interests and energy chokepoints if Iran’s infrastructure is jeopardized, according to Press TV.
The conflict between the U.S. and Iran is approaching a six-month duration, contributing to rising energy prices globally. While intense fighting has decreased, diplomatic attempts to resolve the situation have stalled, and oil and raw material shipments through the Strait of Hormuz remain obstructed, sustaining elevated energy prices.
Trump’s approval ratings have plummeted, with only 33 percent of Americans in the latest Reuters/Ipsos poll expressing satisfaction with his performance. He maintains that the economic burdens are essential to prevent Iran from acquiring nuclear weapons.
For decades, the U.S. has upheld sanctions against Iran, primarily aimed at limiting the nation’s oil income, targeting its aviation sector and cryptocurrency operations, restricting its acquisition of weapons components and military hardware, and cutting off funding for business entities controlled by the IRGC, which plays a significant role in the Iranian economy.
These sanctions prohibit designated entities from accessing the dollar-based financial system, yet Iran has adeptly established new front companies, entities, and vessel registrations to circumvent them.
