Washington rolled out a two‑pronged pressure campaign against Tehran in early 2024. After the Feb. 28 strike named Operation Epic Fury hit Iran’s nuclear and missile sites, the Pentagon and Treasury unveiled Operation Economic Fury on April 16 to choke the regime’s financing. Officials say the economic offensive could eclipse kinetic actions, signaling a shift to coordinated pressure.

The effort splits into sanctions and a naval blockade. Treasury’s Office of Foreign Assets Control (OFAC) will tighten restrictions on financial and logistical channels, zeroing in on oil, gas and even cryptocurrency trades tied to Iran. Simultaneously, U.S. warships will bar any vessel from entering or leaving Iranian ports, tightening the maritime stranglehold. The blockade will also curb humanitarian aid shipments.

For markets, the crackdown threatens Iran’s oil exports, which have underpinned regional energy pricing and exposed multinational firms to compliance risk. Companies with exposure to Iranian shipping or crypto platforms must audit their transactions or face penalties. Investors watch the policy closely as bond spreads tighten, giving Washington a lever that could force Tehran to the negotiating table.
