The United States has announced plans to impose what Treasury Secretary Scott Bessent described as the “toughest sanctions in history” against Iran, marking a major escalation in Washington’s campaign to weaken Tehran’s economy and pressure its leadership.
Bessent said the new measures would form part of an intensified economic strategy aimed at cutting off Iran’s financial lifelines and reducing the resources available to the Iranian government to sustain its military activities.
Speaking on Thursday, Bessent said the United States would provide further details of the sanctions during a press conference scheduled for Monday. He also called on China and other countries that maintain economic relationships with Iran to cooperate with Washington.
The announcement comes as tensions between Washington and Tehran remain extremely high following months of conflict and stalled diplomatic efforts.
Washington Targets Iran’s Economic Lifelines
According to Reuters, Bessent described the planned sanctions as part of a broader “one-two punch,” combining the existing U.S. blockade with significantly tougher financial restrictions.
The Treasury secretary indicated that Washington’s objective was not simply to punish individual Iranian entities but to exert enough economic pressure to undermine the Iranian government.
Bessent argued that increased economic pressure could reduce the need for the United States to undertake another major military operation against Tehran.
The Trump administration has increasingly turned toward economic pressure as the conflict continues, with President Donald Trump warning countries and businesses against providing Iran with financial or commercial support.
China Faces Growing Pressure
China has emerged as one of the most important issues surrounding Washington’s strategy because of its continued economic relationship with Iran.
Reuters reported that China purchases more than 80% of Iran’s shipped oil, according to Kpler data. Washington is therefore seeking Beijing’s cooperation as it attempts to reduce Iran’s ability to generate revenue from oil exports.
Bessent urged China to cooperate with the United States, but Beijing has rejected the idea that sanctions are an effective way to resolve the dispute.
The confrontation could therefore extend beyond Washington and Tehran, potentially creating additional friction between the United States and China at a time when relations between the two powers are already strained.
Iran Warns of Retaliation
Iran has strongly rejected Washington’s approach and warned that further U.S. economic pressure could provoke a severe response.
Iranian officials have described the American sanctions campaign as economic warfare and have vowed to resist attempts to undermine the country's government.
Iranian military chief Major General Ali Abdollahi said the country was prepared to respond across military domains if Washington escalated the confrontation. Parliament Speaker Mohammad Qalibaf also accused the United States and Israel of waging economic and psychological warfare against Iran.
Iranian President Masoud Pezeshkian, meanwhile, has called for an end to the conflict, highlighting the continuing tension between diplomatic efforts and the increasingly confrontational positions of the two sides.
Strait of Hormuz Adds to the Crisis
The sanctions announcement comes against the backdrop of continuing disruption around the Strait of Hormuz, one of the world's most strategically important energy routes.
Iran has said the strait will remain closed until the United States meets conditions connected to an interim agreement, including the lifting of its blockade of Iranian ports, removal of oil sanctions and an end to military pressure.
The disruption has already affected global energy markets. Oil prices were heading toward a second consecutive weekly increase on Friday as investors assessed the impact of reduced oil flows and the possibility of further escalation.
The situation has also affected Iranian oil exports to China. Reuters reported that Iranian oil offers to Chinese buyers had fallen significantly as the U.S. blockade increasingly restricted Tehran's ability to move crude through the region.
Wider Economic Consequences
The planned sanctions could have consequences well beyond Iran if Washington applies secondary sanctions against foreign companies, financial institutions or governments that continue conducting significant business with Tehran.
Trump has already warned countries against providing Iran with what he called a “lifeline,” raising concerns among Iran's trading partners about the potential consequences of continuing commercial relations with the country.
The United Arab Emirates has also taken steps to restrict financial and economic dealings with Iran, adding to the growing pressure on Tehran.
Analysts are watching closely to determine whether the new measures will succeed in forcing Iran back to negotiations or instead deepen the confrontation.
A High-Stakes Economic Confrontation
Washington's latest announcement represents a significant expansion of its economic campaign against Iran. The United States is seeking to combine sanctions, restrictions on Iranian oil exports and pressure on international trading partners in an effort to deprive Tehran of the financial resources it needs.
Iran, however, has shown no indication that it intends to surrender to the pressure without a fight.
With the Strait of Hormuz disrupted, oil markets under pressure and Washington seeking international cooperation against Tehran, the latest sanctions announcement could have consequences far beyond the U.S.-Iran relationship.
The details of the new measures are expected to become clearer when Bessent addresses reporters on Monday. Until then, governments, financial institutions, energy companies and Iran's remaining trading partners will be closely watching Washington's next move.
