U.S. Set to Unveil Largest-Ever Economic Sanctions Against Iran

Washington (Terror Monitor) — The United States is preparing to announce what could be its largest-ever economic sanctions package against Iran, targeting countries and entities that trade with Tehran, Reuters reported Monday. Iran, meanwhile, has threatened to halt all oil exports from the Gulf if the “economic war continues.”

U.S. Treasury Secretary Scott Bessent is expected to hold a press conference Monday to announce additional measures against Iran. Tehran has faced U.S. and international economic sanctions almost continuously since the 1979 Islamic Revolution.

In an opinion article published by the Financial Times on Sunday, Bessent wrote that an “economic D-Day” would begin at the start of Monday, describing it as the largest financial action ever taken against an adversary.

The two rival countries have not exchanged direct military strikes for several weeks, but meaningful negotiations to end the conflict, which has continued for six months, have also failed to materialize.

Without providing details of the new sanctions, Bessent indicated that Washington could also target “fearful countries” that he accused of pursuing “opportunism” by maintaining economic and financial ties with Iran.

He said such countries should consider the consequences of maintaining economic relations with Tehran.

Iran had already been anticipating the new U.S. sanctions, while Iranian officials have issued increasingly tough statements threatening a major military and economic response.

Mohsen Rezaei, secretary of Iran’s Supreme National Security Council, threatened economic retaliation on Sunday.

“If the economic war continues, not a single drop of oil will be exported, neither through the Strait of Hormuz nor through any other route in the Persian Gulf,” Rezaei wrote on social media.

He added that Iran would regard any action by a country participating in or supporting the U.S. economic war against the Iranian people as an act of war.

Meanwhile, according to German news agency DPA, Iranian President Masoud Pezeshkian acknowledged the country’s economic difficulties and said his government was committed to reducing inflation.

In a speech, Pezeshkian said the government was taking measures to bring inflation under control.

The Iranian president also appeared to refer to a recent threat by U.S. President Donald Trump, who has threatened an economic war against Iran following nearly six months of military conflict.

According to the Iranian presidential office, Pezeshkian said Iran was facing a “full-scale economic, military and security war” and that its adversaries had openly threatened to impose unprecedented sanctions on the country.

However, Pezeshkian said the Iranian people remained united and steadfast and that the country would withstand the pressure.
