BBC (analysis) · back to the audit

To break the deadlock, Trump has vowed an 'economic D-Day' under which any country that does business with Iran would face 'tremendous' economic consequences.
Treasury Secretary Scott Bessent promising to reveal them in a news conference on 24 August.
"'You are either with us or against us,' he said. 'If you insist on doing business with [Iran], either transferring money, buying their oil or doing seaborne sea transfers, then the US Treasury and the US government... will put its full might and force toward enforcing against you.'"
"The US has already announced Operation Economic Fury, a two-pronged US economic campaign combining US Treasury-co-ordinated sanctions against regime financial flows and a naval blockade against Iranian ports."
Vice-President JD Vance has described the sanctions as a "new phase" of the conflict in which economic pressure was the "most effective" tool available to the US.
Michael Parker, an eight-year veteran of the Office of Foreign Assets Control, said the new strategy will likely represent an effort to "expand the economic blast radius" of sanctions.
Imran Bayoumi (Atlantic Council): "recognition that the US is almost stuck in this war."
Mohammed Hammouda (London Stock Exchange Group): "Whatever sanctions one does, they find a new road [around it]." "Iran adapting really quickly."
