Trump Signals US Dollar Bans on Chinese Banks over Iran Trade
In this article (7)
US President Donald Trump signaled plans to bar Chinese banks from the US dollar system over their commercial transactions with Iran. The warning follows the blacklisting of 60 international entities, including firms in mainland China and Hong Kong, under an enforcement push labeled Economic D-Day.
Treasury Secretary Scott Bessent announced the initial sanctions package earlier in the week, demanding an immediate halt to commercial dealings with Tehran. The measures aim to intensify economic pressure after six months of regional conflict and disruptions in the Strait of Hormuz failed to resolve through military action or negotiations.
Dollar clearing and secondary sanctions
Bessent stated that any institution facilitating transactions on behalf of Iranian entities faces removal from the US dollar network. The mechanism targets secondary intermediaries, putting Chinese state-owned and commercial lenders at direct risk of losing correspondent banking access in New York.
For corporate treasuries and supply chain operators across Asia, exclusion from greenback settlement creates immediate operational friction. Trade finance across the region relies heavily on dollar-denominated letters of credit, even when settlement involves third-party energy and commodity flows originating in the Middle East.
Pre-summit pressure on Beijing
Commercial lenders in Beijing and Hong Kong have maintained trade settlement channels with trading partners across the Gulf. Cutting those conduits would force corporate clients to route settlement through alternative clearing channels or drop counterparties entirely to protect broader international banking books.
The next test arrives with the scheduled bilateral summit between Trump and Chinese President Xi Jinping in Washington, where trade enforcement and financial sector access sit at the center of negotiations.
