US President Donald Trump has declared what he described as “economic warfare” against Iran, warning countries, businesses and financial institutions that provide economic support to Tehran that they could face severe consequences from Washington.
Trump made the announcement on August 20, 2026, in a post on Truth Social, his social media platform, as the nearly seven-month-old conflict involving the United States, Israel and Iran continues to disrupt energy markets and intensify economic pressure across the Middle East.
What you should know
The latest announcement represents a further escalation of the US administration’s economic pressure campaign against Iran.
Trump’s warning extends beyond the Iranian government to countries, companies and financial institutions that Washington believes are helping Tehran maintain access to international trade, finance or other sources of economic support.
The development comes as the prolonged conflict continues to create uncertainty across global energy markets, with the Middle East remaining a major source of crude oil and other energy supplies.
What they are saying
Trump warned that entities providing what he described as an economic lifeline to Iran would face severe consequences from the United States.
The US president’s latest threat comes after months of fighting between the United States, Israel and Iran, during which Iran has continued attacks on US military assets and bases as well as US allies across the Middle East.
The escalation could increase pressure on businesses and financial institutions with commercial or financial links to Iran, while raising concerns about further disruption to global trade and energy markets.
The conflict has already placed significant pressure on Iran’s economy, while continued hostilities have heightened uncertainty over the direction of oil prices, inflation and broader global economic conditions.
