US to Unveil Harshest Sanctions in History Against Iran

The US is preparing to launch the most severe economic offensive against Iran, aiming to isolate Tehran and its trading partners.

US to Unveil Harshest Sanctions in History Against Iran

The United States is on the brink of launching what it describes as the single greatest financial offensive ever marshalled against an adversary. This escalation comes as the 60-day ceasefire window between the US and Iran has closed without a deal, marking a critical juncture in the six-month war.

Treasury Secretary Scott Bessent announced that he will hold a press conference on Monday to outline these unprecedented sanctions. President Donald Trump has warned of an economic D-Day to break the current stalemate in the Middle East. Meanwhile, Iran has dismissed these threats, calling sanctions an implicit admission of the enemy’s humiliating defeat.

US Treasury Secretary Announces Economic Endgame

Bessent has declared that the US is entering the endgame of its confrontation with Iran. He emphasized that the upcoming sanctions aim to sever every remaining economic lifeline to Tehran. In a post on X Bessent stated, At dawn begins an economic D-Day — the single greatest financial offensive ever marshalled against an adversary.

Iran’s Response and Maritime Restrictions

In response to the US sanctions, Iran’s Ports and Maritime Organization (PGSA) has warned that vessels violating its protocols for the Strait of Hormuz could face restrictions, including fines, detention, or confiscation. The PGSA also announced that vessels cooperating with non-compliant ships would be added to the list of restricted vessels. Additionally, Iran has stated that vessels from authorized countries transiting the Strait of Hormuz will now be required to pay service fees to Tehran.

US Naval Blockade and Market Reactions

The US has enforced a naval blockade against Iran, redirecting 70 commercial vessels, disabling three, and boarding two, according to US Central Command (CENTCOM). This blockade has had a significant impact on global oil prices, with Brent crude falling 1% to $93.43 a barrel and US crude dropping 1.1% to $86.14 ahead of the sanctions announcement.

China has expressed its commitment to promoting peace talks, stating that it continues to support a diplomatic end to the US-Iran war. However, the delayed release of this statement has raised eyebrows, as it was published almost a week after the meeting between Chinese and Iranian officials.

Iran has threatened to halt all oil exports from the Gulf if the economic war continues. Mohsen Rezaei, secretary of Iran’s Supreme national security Council, warned that not a single drop of oil will be exported, neither through the Strait of Hormuz nor from anywhere in the Persian Gulf. He also stated that Iran will regard any country’s participation in or support for America’s economic war against the Iranian people as an act of war.

Parliament Speaker Mohammad Bagher Ghalibaf has criticized Trump’s economic war against Iran, suggesting that it will ultimately backfire on the United States. He questioned how the Trump administration plans to address other economic challenges, referencing recent measures by the US president to control prices of goods.

As the conflict between the US and Iran continues to escalate, the global community watches closely, awaiting the details of the new sanctions and the potential repercussions for the Middle East and beyond.
