Bessent’s Iran Squeeze: Washington’s Last Sanctions Card, Played Against China
(SeaPRwire) – By: Helena Brooks
Scott Bessent walked into the Treasury with a theatrical promise. Economic Fury. Unprecedented pressure. Critics laughed. Iran is already under a naval blockade and buried under thousands of sanctions. The question is not whether Washington has tools left. It is whether any of them actually bite without snapping back on the American economy.
China absorbs over ninety percent of Iran’s oil exports. The Treasury has slapped penalties on a handful of Chinese teapot refineries since the conflict escalated in late February. It has not touched the major banks financing the trade. That restraint is deliberate. Hitting Beijing’s financial system would ignite a collision ahead of the Trump-Xi summit. And removing discounted Iranian crude from global markets would push oil prices higher, exactly where American consumers do not need them.
This is the core contradiction of Bessent’s posture. He is signaling maximum pressure while the Treasury knows that maximum pressure means maximum self-harm. China’s May directive ordering domestic companies not to comply with US sanctions on five refiners is not a warning. It is a declaration of fait accompli. Those Chinese banks caught between Washington’s threats and Beijing’s commands are already operating in a gray zone. Sanctioning them further would not expand US leverage. It would simply force every dollar of Iranian trade deeper underground.
The remaining playbook is narrower than the rhetoric suggests. Secondary sanctions on Iran’s broader trading partners were floated by Trump as a twenty-five percent tariff threat. He has not followed through. The mechanism is real but diplomatically corrosive. Turkey, a NATO ally with significant commercial ties to Tehran, would be collateral damage. Russia benefits from pressure. Neighbors of Iran do not.
Exchange houses in the UAE and other Gulf states remain a viable target. The Treasury has already sanctioned a number of them under the Economic Fury campaign for allegedly laundering billions in foreign currency. Cutting off specific channels will not stop the flow. Iran has spent years building alternative routes. Transactions will shift toward new intermediaries, different currencies, or digital assets. The pressure is incremental. It is not decisive.
The most dramatic option on the table is asset confiscation. Washington could go beyond freezing Iranian state assets and seize them outright, invoking a precedent from the Bush administration after the 2003 Iraq invasion. The problem is the pool of reachable assets is small. Most of Iran’s overseas wealth sits in third countries. Confiscation requires foreign cooperation. It also requires Washington to accept the diplomatic blowback of openly expropriating sovereign wealth without a formal legal basis.
The shadow fleet is the final pressure point. A US naval blockade has already reduced traffic to Iranian ports. The Treasury could expand its targeting to include the companies, terminals, and infrastructure enabling shipments, not just individual vessels. This is more actionable than broad secondary sanctions. It is also more likely to face practical limits. Shadow fleet operators are already adapting. Sanction evasion is a market. Pressuring one node simply migrates the risk elsewhere.
The real constraint is not Iran’s resilience. It is America’s. Bessent’s threat only carries weight if the White House is willing to absorb the economic cost. Prioritizing Iran over China is a strategic choice with tangible consequences. The Treasury knows this. The administration knows this. The rhetoric is loud because the options are thin.
