U.S. Treasury Secretary Scott Bessent said the United States will soon roll out economic measures against Iran unlike anything previously deployed, intensifying pressure on Tehran nearly six months into the broader conflict between the two countries. Speaking in a Newsmax interview, Bessent said to “watch this space for more announcements coming next week because we are going to apply measures like have never been seen in the history of economic isolation on a country.”
Bessent described the coming package as part of a “one-two punch” that pairs the new economic measures with the continued naval blockade of the Strait of Hormuz, the narrow waterway through which a substantial share of the world's seaborne oil trade passes, aimed at preventing goods from moving in or out of Iranian ports.
An Escalation on Top of an Existing Blockade
The announcement builds on measures already in place rather than replacing them. U.S. officials have maintained that the Strait of Hormuz blockade can be sustained indefinitely, and Bessent's comments suggest the administration now intends to layer a more aggressive financial-isolation campaign on top of that physical chokehold rather than treating the blockade alone as sufficient pressure. Treasury officials have separately described plans to “hunt down and dismantle” Iran's financial networks, signaling the new measures will likely target the intermediary banks, shadow-fleet tankers and trading networks Iran has used to route oil sales around existing sanctions.
The push comes as talks between the two countries remain stalled, with the administration framing the expanded economic-isolation package as leverage meant to be sustained over an extended period rather than a short-term pressure tactic tied to a specific negotiating deadline.

Why Markets Are Watching
Iran remains a significant global oil producer and exporter despite years of existing sanctions, and any measures that materially disrupt its remaining export channels carry the potential to tighten global crude supply further at a moment when the region is already dealing with repeated attacks on Saudi refining infrastructure. Markets have already begun pricing in elevated geopolitical risk from the broader conflict; a genuinely unprecedented sanctions package, if it succeeds in choking off Iran's remaining oil revenue, would add another layer of supply uncertainty on top of the direct physical disruptions the conflict has already caused to regional energy infrastructure.
