US Treasury prepares "toughest" Iran sanctions as Tehran shrugs off economic threat
Scott Bessent is set to unveil a new package of measures against Tehran, which he has described as the most severe in history, even as Iranian officials dismiss the prospect of economic warfare.

US Treasury Secretary Scott Bessent is scheduled to announce a new package of sanctions against Iran, a move that marks a significant escalation in the ongoing economic standoff between the two nations. Speaking to CNBC, Bessent characterised the upcoming measures as the "toughest" in history, signalling Washington’s intent to intensify pressure on Tehran’s financial systems.
The announcement comes after nearly six months of conflict between the US and Iran, a period during which previous diplomatic efforts to reach an agreement have stalled. President Donald Trump has previously described the broader strategy as a "crushing economic operation," indicating a shift towards more aggressive financial tools to influence Iranian policy.
Despite the severity of the new measures, Tehran has publicly dismissed the threat of economic warfare. Iranian officials have maintained a firm diplomatic stance, suggesting that the country is prepared to withstand the financial strain imposed by Washington’s latest actions.
However, the move complicates efforts to build a broad international coalition. Tehran has warned that any country participating in the US-led campaign will be treated as an enemy, forcing other nations to weigh the benefits of joining the sanctions against the risk of being classified as adversaries by Iran.
Regional tensions remain high, with recent disputes over the Strait of Hormuz adding to the uncertainty. Reports indicate that ships have been struck in the waterway, and Iran’s deputy foreign minister has stated that the strait "will remain Iranian," rebuffing US claims that it would soon become US territory.
For investors and institutions, the lack of specific details on the scope of the new sanctions introduces an element of volatility. While the Treasury has framed the move as a decisive step, the precise impact on global markets and trade routes remains to be seen.
