US Treasury Announces New Iran Bank Sanctions

US Treasury Secretary Scott Bessent said on Tuesday that Washington was likely to announce bank sanctions against Iran this week, with another expected the following week. Speaking at a G20 finance leaders' meeting in Asheville, North Carolina, Bessent said, "We're probably going to announce a bank sanction this week and we are going to have another one the week after."

Bessent warned that the US was intensifying action across digital assets, aviation, and maritime networks, and that enforcement could reach banks, airline leasing companies, and any entity doing business with the Islamic Revolutionary Guard Corps (IRGC). "We have zero tolerance. We are going to economically asphyxiate this regime," he said.

He also cited the case of a branch of an Egyptian bank in Dubai that he said had funneled more than $1.8 billion to the Iranian government, noting that the US used the Patriot Act to shut down the operation. Bessent added that Washington had located accounts in the British Virgin Islands and properties around the world that would be frozen.

The Treasury Secretary said the administration had received support from the European Union, the European Central Bank, Britain, and the United Arab Emirates. He also mentioned private discussions with China, saying, "The Chinese agree Iran cannot have a nuclear weapon."

Iran's Defiant Response

Iranian officials responded with defiance. Parliament speaker Mohammad Baqer Qalibaf was quoted by Iranian media as saying, "If the enemy wants us not to export oil from the Persian Gulf, no one will be able to export oil."

President Masoud Pezeshkian said Tehran would reciprocate immediately if Washington honored its commitments under a June Memorandum of Understanding. Foreign Ministry spokesman Esmaeil Baghaei accused Washington of being "addicted to making excessive demands and has mistaken negotiations for dictating terms," and warned that Tehran would "use all our capabilities, whether on the battlefield or through our diplomatic apparatus."

Escalation and Economic Impact

The announcements come after a weekend of direct military exchanges. US forces attacked Iran's Larak Island on Sunday, and Iran responded by launching missiles at two US air bases in Jordan. President Donald Trump told reporters on Monday that the strikes did not signal a return to full-scale war. A senior Iranian source told Reuters the strikes were a "limited and contained confrontation."

Brent futures rose more than 2% on Tuesday following the attacks and reports that two supertankers carrying Saudi oil were struck by unknown projectiles while transiting through the Strait of Hormuz, according to shipping intelligence firms Marisks and Kpler.

PVM analyst John Evans said, "The tit-for-tat missile exchanges between the S. and Iran bring validation to those who believe that even if not a 'forever war', this conflict will run and run."

On the economic front, Iran's central bank governor, Abdolnaser Hemmati, said Tehran had sufficient foreign currency reserves and was ready to inject up to $2 billion into the foreign exchange market to calm volatility. Iran's currency plunged to a record low in August, crossing 2 million rials to the dollar, with annual inflation at 66% in July.
