Washington: US President Donald Trump has dramatically expanded his economic pressure campaign against Iran, warning countries, companies and financial institutions that provide Tehran with a financial or commercial lifeline could face severe economic consequences. The latest move marks a significant escalation in Washington’s strategy as diplomatic efforts to resolve the conflict remain stalled.
Trump announced the new campaign on social media, describing it as the “most crushing economic operation” ever undertaken against a country and calling it economic warfare and isolation on an unprecedented scale. He warned that the measures would not be limited to Iran itself but could also target entities that help Tehran maintain access to international trade and finance.
According to the latest details, Washington is looking at a broad range of economic channels that could provide Iran with revenue. Trump specifically highlighted activities including oil smuggling, currency swaps, cash transfers, exchange houses, ship registries and front companies. The threat could therefore extend beyond traditional sanctions against Iranian individuals and organisations and put pressure on third-country businesses involved in Iran-related transactions.
The announcement comes after weeks of increasing US pressure on Tehran. The Trump administration has already sanctioned more than 1,000 individuals and entities linked to Iran, with particular attention on the country’s oil trade, shipping networks and financial channels. US officials are also considering additional measures targeting Chinese independent oil refineries and potentially financial institutions that process Iranian funds.
The Strait of Hormuz remains at the centre of the confrontation. The strategically important waterway is a major route for global oil shipments, and disruptions there have already affected shipping and energy markets. Washington has been attempting to use economic and maritime pressure to push Tehran towards an agreement that would reopen the waterway and address broader US demands.
The latest escalation also comes as diplomatic efforts have struggled to produce a breakthrough. A previously discussed 60-day framework expired without a lasting resolution, while Washington and Tehran have continued to exchange conflicting messages about the possibility of renewed negotiations. Trump has indicated that talks could resume at some point, but his administration is simultaneously preparing stronger economic measures.
Iran has rejected Washington’s approach and criticised the economic pressure campaign, with Iranian officials portraying the US strategy as economic coercion rather than a path towards diplomacy. Tehran has shown little indication that the latest threats will immediately force it to accept Washington’s demands.
The pressure is also creating challenges for Iran’s major trading partners. China remains an important buyer of Iranian oil, meaning any attempt to impose tougher secondary sanctions on Chinese companies or banks could significantly raise tensions between Washington and Beijing. Analysts have warned that targeting major Chinese financial institutions could trigger a wider economic and diplomatic confrontation.
Meanwhile, the United Arab Emirates has suspended trade and financial transactions with Iran following renewed missile-related tensions, further narrowing Tehran’s regional economic options. The UAE had been an important commercial and re-export hub for Iran.
Trump’s expanded economic campaign therefore represents more than another round of Iran sanctions. It signals an effort to pressure Iran’s entire international economic network—from oil revenues and shipping to banks, businesses and trade partners. Whether the strategy pushes Tehran back to negotiations or deepens the wider regional conflict remains a key question in the days ahead.
