US Treasury Secretary Scott Bessent said Washington would launch what he characterised as its most extensive financial campaign against Iran, severing all US economic ties with the country and seeking to isolate nations that continue financial partnerships with Tehran. His comments were reported on 24 August 2026.
Bessent’s statement indicates that the planned pressure would not be confined to direct dealings between the United States and Iran. Countries that maintain financial relationships with Iran would also face isolation under the approach he outlined, potentially widening the scope of the US campaign to international partners of Tehran.
The available report does not specify which countries, banks, companies or sectors Washington may target. It also does not provide a timetable for cutting economic ties, explain what form the threatened isolation would take, or identify the legal and regulatory measures that the US Treasury would use.
It is therefore not yet clear how the announcement will be implemented or how other governments may respond. No Iranian response was included in the supplied evidence. Further details would be needed to establish the practical reach of the policy and which existing financial relationships could be affected.
