US Launches ‘Economic D-Day’ on Iran, Targeting China Trade Ties

The Trump administration has unveiled a sweeping new sanctions campaign against Iran, dubbed “Operation Economic Outcast,” aiming to cut off the country’s remaining financial and trade lifelines rather than rely on further military strikes. Treasury Secretary Scott Bessent announced the measures on August 24, warning that any nation or entity trading with Iran — including China, Iran’s largest oil buyer — could be cut off from the US dollar financial system. China immediately rejected the move as illegal and vowed to protect its interests, while Iran said it was “fully prepared” to counter the pressure.

What exactly did Bessent announce?

Bessent framed the campaign in explicitly historic terms, comparing it to the D-Day invasion that helped defeat Nazi Germany. He said the US would target five specific channels Iran uses to move money and goods: digital assets, technology, gold, aviation and shipping. The initial rollout sanctioned around 60 individuals, entities and vessels accused of helping Iran evade existing restrictions. Bessent said any entity caught laundering money for Iran would be “removed from the US dollar-based financial system,” adding, “the countdown starts now.” He called it “the single greatest financial offensive ever” against Tehran and said the goal was to isolate the regime “until Tehran stands alone.”

Why didn’t the US sanction Chinese banks directly?

Despite China buying an estimated 80–90% of Iran’s oil exports, no major Chinese financial institutions appeared on the initial sanctions list. Bessent, asked directly about this omission, replied: “Why would I want to blow up the global financial system?” Analysts cited by the Guardian and BBC say this reflects Washington’s caution ahead of a planned summit next month between Donald Trump and Chinese President Xi Jinping, and awareness that Beijing could retaliate by restricting exports of rare earths and critical minerals it dominates globally. Bessent did say Trump would personally call world leaders asking them to cut ties with Iran, and insisted “no one was above the reach of US sanctions.”

How has China responded?

China’s foreign ministry spokesman Lin Jian called the sanctions “illegal unilateral sanctions” and said Beijing would take “all necessary measures” to safeguard its rights and interests. He said Chinese-Iranian cooperation has always operated within international law and should not be disrupted. Trade with Iran has already declined under the US naval blockade of Iranian ports — shipments to China fell from a peak of about 1.58 million barrels per day earlier this year to roughly 534,000 barrels per day in August, down from 823,000 in July.

How is Iran reacting, and how bad is its economy?

Iranian Economy Minister Ali Madanizadeh said Tehran had a “two-year plan” to manage the fallout and had “been waiting for these plans for a long time,” adding, “we also have our own tools and know how to play the game.” He struck a defiant tone, saying Iran’s posture was “no longer so defensive” and that “enemies should wait for an attack.” On the ground, the toll is visible: Iran’s rial hit an all-time low of 2.02 million to the dollar just before Bessent’s announcement, food prices rose about 128% year-on-year in July, and property and car sales are increasingly conducted in dollars rather than rial. A Tehran building-materials seller told Deutsche Welle that inflation is now so severe that holding inventory can be more profitable than selling it.

Where does this leave the wider conflict?

The sanctions come roughly six months into the Iran war and shortly after a 60-day ceasefire expired without a settlement. Iran has effectively restricted exports through the Strait of Hormuz, and the US has slowed traffic there with its own naval presence; an oil tanker was reportedly struck by an unidentified projectile near the strait’s mouth this week, with only two commercial vessels said to have transited on Monday. Analysts told Fox News that sustained economic pressure could eventually help trigger a domestic uprising against Iran’s clerical leadership, though they stressed the timing of any such unrest is impossible to predict. Others note the shift toward economic rather than military tools suggests Washington still has no clear path to ending the conflict, and that the campaign’s success hinges largely on whether China — increasingly economically resilient — can be pressured to comply.
