He's launched what Treasury Sec. Bessent describes as an unprecedented campaign to sever every financial lifeline keeping Tehran alive.
Washington says it will go after the banks, oil traders, shipping companies, crypto networks and foreign entities helping Iran circumvent American pressure.
But one question exposes just how enormous this could become: What about China?
Iran can only be economically isolated if the countries still doing business with it cooperate. If they don't, America's secondary sanctions eventually have to reach them too.
Enforce Operation Economic Outcast too selectively, and Iran keeps finding routes around it.
Enforce it ruthlessly enough to genuinely isolate Tehran and Washington risks a much larger confrontation with the countries, banks and businesses refusing to comply.
For all the extraordinary rhetoric, though, this also represents a significant movement down the escalation ladder.
Weeks ago, Trump was threatening Iran with annihilation, and people were discussing ground troops and even nuclear escalation.
Now Washington's principal weapon is the Treasury; the war has moved from bombs to banks.
That's unquestionably preferable to Americans and Iranians killing each other, but it also suggests Washington is searching for another way to extract concessions it couldn't force militarily.
Iran's negotiating position remains extremely ambitious: control over Hormuz, substantial shipping fees, reparations and the removal of American bases from the region.
The precise details remain uncertain, but Washington clearly isn't prepared to accept the position as it currently understands it.
So Trump needs leverage, and Operation Economic Outcast is designed to create it.
The problem is that sanctions take time. Banks and companies adapt, trade gets rerouted, and new payment mechanisms emerge. Meanwhile, Washington wants Hormuz normalised, and energy markets stabilised quickly.
And Iran is already signalling that it won't simply absorb unlimited pressure without responding.
That creates the risk of a new escalation cycle: America squeezes Iran, they refuse to concede, Washington targets the countries keeping Tehran afloat, and Iran increases the cost for countries helping Washington.
The bombs may have stopped falling, but Trump has replaced the military war with an economic gamble that could reach far beyond Iran.
