Scott Bessent warned non-Chinese buyers of Iranian oil that they “deal with Tehran at your own risk,” putting them on notice as the US Treasury sharpens its sanctions posture. The warning targets buyers and banks outside China, where the pressure campaign is already narrowing the market for Iranian crude.
The Treasury’s latest line is part of a broader effort to choke off Iran’s revenue streams. Banks that facilitate Iranian oil transactions face potential cutoffs from the US financial system, a consequence that can reach beyond the cargo buyer and into the payment chain.
US Treasury pressure campaign
China remains the dominant buyer of Iranian oil, while the Treasury is aiming at non-Chinese buyers that have kept the trade moving. That leaves a narrower set of counterparties exposed to the risk of losing access to dollar clearing and other US financial channels if they continue handling Iranian crude.
For buyers, the practical issue is not just whether they can purchase oil, but whether the bank handling the transfer is willing to stay in the transaction. When that bank steps back, the trade becomes harder to settle and more expensive to move.
OFAC and Nobitex
The oil warning came alongside a separate Treasury enforcement push against Iranian-linked digital assets. On June 2, OFAC sanctioned Nobitex and three other Iranian digital asset platforms, and accused the platforms of helping the regime sidestep financial restrictions.
That action made it illegal for US persons to transact with the sanctioned exchanges. The Treasury has also seized approximately $1 billion in crypto assets linked to Iran, showing that the pressure campaign is extending beyond oil sales to the financial tools that help move value around them.
Non-Chinese buyers
Non-Chinese buyers are already growing more cautious and stepping back from Iranian crude. The warning from Bessent puts a clearer line under the risk: if they keep buying, the exposure is no longer limited to cargo or shipping problems, but to sanctions consequences that can reach the institutions moving the money.
The open question now is which countries or companies still sit in that non-Chinese buyer pool. For anyone still handling Iranian oil, the Treasury has made the cost of staying in the trade harder to ignore.
