Washington has opened a new front in its economic campaign against Tehran, with Treasury Secretary Scott Bessent declaring that frozen Iranian assets will be used to compensate Gulf allies for any damage inflicted on them and to offset tolls demanded by Iran for transiting the Strait of Hormuz. In a social media statement, Bessent framed the confrontation as a 'zero-sum game' that Tehran would inevitably lose, signalling a readiness to escalate financial pressure far beyond conventional sanctions. The immediate trigger is Iran's recent assertion that it will levy fees on vessels passing through the strait – a threat the US has vowed to neutralise by seizing the regime's own sequestered funds.

Viewed from Washington, the move serves a dual purpose: it reassures nervous Gulf partners that the US will back them against Iranian aggression while reinforcing the message that the Strait of Hormuz remains an international waterway. For Saudi Arabia, the UAE and other littoral states, the pledge is a concrete deterrent – but it also embeds them deeper in a US-led financial architecture that could draw retaliatory strikes. Moscow-based reports note that Bessent explicitly linked future hostilities to deeper economic pain for Tehran, a logic that some analysts in London suggest could incentivise the Iranian leadership to test American resolve before the asset-seizure mechanism becomes operational.

In Tehran, the threat is being depicted as a colonial-style confiscation and a violation of sovereignty. Iranian media outlets relayed Bessent's language with an edge of alarm, highlighting his reference to the 'Persian Gulf Strait Authority' – the entity Tehran claims has the right to manage transit. By declaring that any tolls paid to that authority will be offset by debiting frozen accounts, the US is in effect declaring that it will recognise no such Iranian levy. This direct financial countermeasure, should it be implemented, would strike at the heart of Iran's attempt to monetise its geographic position, a strategy the Islamic Republic has long brandished as a bargaining chip.

Whether the threat proves effective or escalatory depends on the opaque scale of frozen Iranian assets and the willingness of third countries to facilitate their seizure. The bulk of these funds are believed held in East Asian and European banks, beyond immediate US jurisdiction, meaning implementation would require a new round of diplomatic strong-arming. Forward-looking assessments from regional analysts suggest that even if the offset mechanism remains largely rhetorical, it has already raised the stakes in the maritime stand-off. With Washington insistent that Iran will 'deepen its economic and financial consequences' with any new attack, the risk of miscalculation along the world's most vital oil chokepoint has rarely been higher.
