Treasury Secretary Scott Bessent unveiled "Operation Economic Outcast" on Monday, calling it an "economic D-Day" against Iran. The campaign expands secondary sanctions on anyone doing business with Tehran. It also adds new penalties across digital assets, gold, aviation, technology, and shipping, and blacklists nearly 60 people, companies, and vessels. Bessent said enforcement won't be immediate. Countries get a "cure period" to change course first, and he declined to set a deadline. He signaled China isn't exempt. China's Foreign Ministry called the new sanctions counterproductive today, and Beijing has separately ordered its companies, since May, to defy such sanctions outright. Iran's Strait of Hormuz authority threatened to seize violating vessels, and Iranian officials floated cutting off the Strait entirely. The war, which began February 28, hit a deadline for a lasting deal on August 17 without a resolution.

1. The Administration (Treasury Secretary Scott Bessent)

Bessent is betting sanctions end this war, not more strikes.

Bessent is pivoting from military strikes to economic pressure. He framed Operation Economic Outcast as the main event, not a sideshow to the war. He called it an "economic onslaught" meant to cut off Iran's revenue instead of ordering more strikes.

Washington is really aiming this at China. Bessent said Treasury will target any entity that turns Iranian oil "into money, into repression," and confirmed China isn't exempt. China buys more than 90% of Iran's oil exports, so the sanctions only work if Beijing complies.

Bessent built the rollout to move slowly, on purpose. Countries get a "cure period" before sanctions actually bite, and Bessent wouldn't commit to a deadline: "I'm not going to set a timeline, but we do not have infinite patience here." The blacklist of nearly 60 people, businesses, and vessels is just the start — more sanctions are coming.

2. Iran and China (President Masoud Pezeshkian, Iran's Persian Gulf Strait Authority, China's Foreign and Commerce Ministries)

This isn't Washington ending the war. It's Washington admitting it can't win the war it's already fighting.

Iran says it's already fighting on every front. President Masoud Pezeshkian said Sunday, "We are apologetic that these problems exist, as we find ourselves in a full-scale economic, military, and security war." Iranian officials have separately called the new sanctions campaign an admission of U.S. failure.

Iran is threatening the world's most important oil chokepoint. Before the war, the Strait of Hormuz carried roughly a fifth of global oil and gas supply. Iran's Strait Authority warned it could fine, seize, or confiscate vessels that violate its transit rules, and Iranian officials have floated shutting the Strait down entirely if the sanctions push continues.

China is pushing back two ways. China's Foreign Ministry said today that sanctions "cannot resolve problems, as they only heighten tensions, escalate the situation," and that Beijing will "take necessary measures to safeguard its legitimate rights and interests." Beijing's diplomatic pushback builds on a standing order from May. That order tells Chinese companies to ignore U.S. sanctions on firms buying Iranian oil — a direct government instruction to defy Washington, not a workaround.

3. War-Weary Americans and Senate Democrats (Sens. Tim Kaine and Jeff Merkley)

Congress never voted for this war, and most Americans have stopped backing it.

Fewer Americans back the war now than ever. A Reuters/Ipsos poll out Monday put approval at 31%, down from 37% in March. Republican support slipped too, from 77% to 69% over the same stretch.

Sen. Tim Kaine (D-VA) calls this a war of choice. "President Trump's deeply unpopular war of choice in Iran has imposed a tremendous cost on the American people — including deaths and injuries of our servicemembers and soaring gas prices," Kaine said.

Merkley says the administration keeps Congress shut out. Sen. Jeff Merkley (D-OR) has called the war "Operation Epic Failure" and accused the administration of "dangerous incompetence" for refusing to give Congress straight answers. He and Kaine have repeatedly forced War Powers Resolution votes to end the war. Senate Republicans have blocked every one of those votes, so the war continues without a fresh congressional vote — and so does the sanctions campaign. Independents currently favor Democrats over Republicans on the generic ballot by 33% to 19%.

Where This Lands

Bessent says the sanctions campaign is how the U.S. wins without more strikes. Iran and China are answering with defiance, not compliance, and Iran is holding the Strait of Hormuz as leverage. Back home, the war's approval rating is at its lowest point yet, and the senators trying to end it keep losing the vote. Markets aren't betting the sanctions land as hard as advertised. Oil prices fell the day Bessent announced them, and the IMF has already trimmed its 2026 global growth forecast to 3.0%, citing the war.
