How the US could squeeze Iran with economic isolation – and the risks involved
The Treasury Department is exploring targeting Chinese banks, shadow fleets and exchange houses, but secondary sanctions risk economic blowback

Treasury Secretary Scott Bessent says the US is getting ready to squeeze Iran with unprecedented economic pressure, a claim critics greeted with scepticism given the country is already subject to a naval blockade and thousands of sanctions.
While the Trump administration has not said what it is planning to do, there are still pressure points that Bessent’s Treasury Department could hit. The main challenge is that targeting the remaining options risks blowback on the US economy.
“Unless the president decides to prioritise addressing the Iran threat over all other issues, and namely China, it’s unlikely any action they take is going to materially change Iran’s calculus,” Bloomberg Economics analyst Chris Kennedy said.

Below is a look at a few options. They are far from exhaustive and it remains unclear which, if any, the administration will pursue. Officials could combine several of these measures or opt for a different approach altogether.
China buys more than 90 per cent of Iran’s oil exports. Penalties on entities that facilitate these purchases would directly reduce Tehran’s oil revenues.
