U.S. Vows 'Unseen' Economic Measures Against Iran, Escalating Sanctions

U.S. President Donald Trump has pledged to impose severe economic pressure on Iran, with the Treasury Secretary indicating 'never before seen' measures could be implemented as early as next week. Washington has already levied additional maritime, energy, and financial sanctions and initiated a naval blockade since the Iran war began in February. Recent actions have targeted Iran's shadow oil fleet, shipping insurers, and entities facilitating weapons acquisition, freezing an estimated $500 billion in Iran-linked cryptocurrency. Experts suggest further options include sanctions on Chinese 'teapot' refineries and larger Chinese banks, though this risks retaliatory actions from Beijing.
