US threatens unprecedented economic pressure on Iran

The escalation of US sanctions on Iran threatens to further disrupt global oil markets, particularly given China's significant purchases of Iranian crude, potentially raising oil prices and shipping costs. Sanctions on Chinese banks and refiners could chill international trade and financial flows, while the threat of secondary tariffs adds uncertainty for global businesses.
US President Donald Trump vowed on Friday to hit Iran hard economically, following Treasury Secretary Scott Bessent's statement that Washington would impose measures on Tehran that have 'never been seen' as soon as next week. Since the Iran war began in February, the US has levied additional maritime, energy, and financial sanctions and started a naval blockade. The United States — Office of Foreign Assets Control (OFAC) has imposed sanctions on more than 1,000 people, vessels, and aircraft since Trump began his second term, including targeting Iran's shadow oil fleet, shipping insurers, entities enabling weapons acquisition, and digital exchanges, freezing an estimated $500 billion in Iran-linked cryptocurrency. Experts outline potential further actions: sanctions on Chinese 'teapot' refiners that buy over 80% of Iran's shipped oil; secondary sanctions on Chinese banks, with two larger banks warned; continued 'whack-a-mole' targeting of sanctions evaders; a possible land blockade requiring cooperation from Iran's neighbors; and secondary tariffs, though the Supreme Court struck down the legal basis for such taxes. The Senate passed a Russia sanctions bill including new Iran sanctions and tariff powers, but it faces challenges in the House. The administration is also mindful of potential Chinese retaliation on critical minerals exports.
