History

Historical Context

After radical students seized the U.S. embassy in Tehran in November 1979, President Carter’s Executive Order 12170 froze roughly $8.1 billion of Iranian assets and launched the first comprehensive OFAC sanctions. Decades later, the Trump administration revived that framework, targeting Amin Exchange’s owners Yousef Ebrahimi and Samad Nemati and dozens of vessels linked to China, the UAE and Turkey, extending pressure on Iran’s maritime trade.
