Iran has announced it is "fully prepared" to withstand and counter a significant expansion of U.S. economic sanctions, which Washington has characterized as an "economic D-Day" aimed at isolating the country from the global economy. The declaration comes as the U.S. Treasury Department unveiled new measures designed to tighten pressure on Tehran's revenue streams.

Iranian Economy Minister Ali Madanizadeh stated that Tehran anticipates these sanctions will ultimately result in another defeat for the United States. The announcement from Washington signals a significant escalation in economic warfare, with Treasury Secretary Scott Bessent asserting that any nation financially partnering with Iran will face isolation. Banks and businesses that continue to deal with Iran risk sharing in its isolation if they do not sever ties.

These intensified measures follow a period of shifting U.S. policy and extended deadlines concerning the ongoing conflict. Bessent described the new actions as the "single greatest financial offensive ever against Iran," intended to "tighten the noose and block every potential source of revenue." Key trading partners for Iran, including China, Turkey, and the United Arab Emirates, are now under direct pressure. The UAE had previously announced a halt to all trade and financial transactions with Tehran.

Hours after the U.S. announcement, Iran expressed confidence that its trading partners would continue their business relationships. Madanizadeh specifically stated that neither China nor Russia had accepted the U.S. measures, predicting broad international resistance. He revealed that the Iranian government has a "two-year plan to manage these events," indicating preparedness and a long-standing anticipation of such actions. "We also have our own tools and know how to play the game," Madanizadeh added.

The Chinese Foreign Ministry echoed this sentiment, with a spokesperson stating that "sanctions and pressure tactics do not help." Beijing affirmed its intention to take necessary steps to protect China's interests. The broader economic implications of the conflict have already contributed to rising global oil prices. In response to the latest U.S. threats, Iran has warned of potential disruption to oil exports from the region if the conflict persists.

Furthermore, Iran has issued a fresh warning to ships, advising them against passing through the Strait of Hormuz without permission, according to Reuters. This narrow waterway, crucial for global energy transport, typically sees one-fifth of the world's oil and gas flow. Its flow has been effectively impacted since the conflict began in late February, contributing to increased global oil prices.

During a press conference detailing "Operation Economic Outcast," Secretary Bessent outlined the U.S. strategy as an "economic onslaught against Iran's financial connections around the globe." He presented Iran with a stark choice: "complete global isolation... or a path back to normalcy with an opportunity to rejoin the global economy." Bessent declared that America is no longer merely managing the Iranian threat but is "ending it."

The Treasury Department indicated it has identified and mapped networks, facilitators, and financial channels used by Iran to circumvent sanctions, particularly in oil trading. The department has issued determinations against five key sectors, including digital assets, technology, and others, signaling a comprehensive approach to cutting off Iranian financial lifelines.
