US Launches Major Financial Offensive Against Iran, Warns Allies Against Cooperation

On August 24, 2026, US Treasury Secretary Scott Bessant announced the start of an unprecedented economic campaign against Iran, describing it as the largest coordinated financial attack ever directed at a rival. He declared that the "D-Day" of this financial offensive would begin at dawn (Israel time), with new sanction packages expected to be unveiled the same day. Bessant warned that any country acting as a financial conduit for the Iranian regime would face isolation and be branded a pariah by the United States, emphasizing that becoming a haven for terrorism would result in international ostracism.

Bessant stressed the US administration's determination to sever all economic ties with Tehran, stating that nations cutting remaining trade links would strengthen their global financial credibility and market trust. Conversely, those maintaining connections with Iran risk accelerating their economic exclusion. He highlighted that Iran had previously relied on coercion and miscalculated US enforcement, but under President Trump, that era has ended.

The Treasury Secretary also addressed the possibility of Iranian military escalation amid economic collapse, warning that any attack on US forces or Gulf neighbors would provoke a swift and decisive American response. Meanwhile, diplomatic efforts continue in Tehran, where Pakistan's Army Chief Asim Munir arrived to revive talks with Washington. Additionally, Oman's Foreign Minister Badr al-Busaidi is scheduled to visit Tehran to discuss control over the strategic Strait of Hormuz.

This dual approach of intensified sanctions and diplomatic engagement reflects the complex dynamics surrounding Iran's economic and geopolitical position in the region.
