Treasury Secretary Scott Bessent announced a sweeping campaign of economic sanctions on Iran on Monday, August 24, 2026, dubbed “Operation Economic Outcast,” targeting nearly 60 entities, individuals, and vessels while threatening secondary sanctions against countries that continue trading with Tehran.
The Treasury Department’s Office of Foreign Assets Control (OFAC) designated specific sanctions on Iranian defense ministry procurement networks, cybercriminal groups, and oil trading operations, according to Reuters. Bessent described the campaign as an “economic onslaught” designed to foreclose every remaining economic option available to the Iranian regime.

The new sanctions broaden the scope of secondary sanctions to five vital sectors of Iran’s economy: digital assets and cryptocurrency, technology, gold, aviation, and shipping. Reuters reported that the Treasury also targeted Iran’s Special Trade and Finance Institute (STFI), an alternate financial system the regime established to circumvent existing sanctions.
Bessent warned that any entity facilitating money laundering or sanctions evasion for Iran would be cut off from the U.S. financial system. The campaign also identified five tankers as part of Iran’s “shadow fleet” and listed them as blocked property, prohibiting U.S. nationals from any financial dealings with them, according to Reuters.
The Treasury set timelines for other governments to shut down economic activity with Iran but stopped short of naming specific countries that would face secondary sanctions or specifying when those penalties would take effect. This strategy mirrors the U.S. approach first significantly deployed against Iran in 2010, when secondary sanctions began compelling foreign companies and banks to withdraw from Iran, according to the Center for a New American Security.

Analysts cautioned that despite the scale of the new measures, Iran has survived decades of previous sanctions and may escalate rather than surrender. “Iran has survived decades of sanctions. Faced with more, it is likely to escalate rather than surrender, analysts said,” according to reporting by the New York Times on August 19, 2026, ahead of the announcement.
Iran responded to the announcement with warnings. According to the internal links pool, Iran declared that countries joining the U.S. economic campaign would be treated as “enemies,” signaling defiance to the broader isolation strategy.
