The US Treasury Department has been waging a sustained campaign against sprawling fraud networks in Southeast Asia, sanctioning hundreds of individuals and entities tied to crypto scam operations that have drained billions from American victims. Under Secretary Scott Bessent, the effort has escalated from targeted designations to one of the most aggressive anti-fraud pushes in the department’s recent history.

The numbers tell the story. Americans lost at least $10 billion to scams originating from Southeast Asia in 2024, a 66% increase from the prior year. Total online investment scam losses have exceeded $16.6 billion in recent years.

A rolling wave of sanctions

The Treasury’s Office of Foreign Assets Control has executed multiple rounds of sanctions across several months, each one expanding the net wider. On September 8, 2025, OFAC sanctioned nine targets in Burma and ten in Cambodia connected to virtual currency scams. The Burmese side of the operation was linked to the Karen National Army.

Then came October 14, 2025, when the US and UK jointly sanctioned 146 targets tied to the Prince Group Transnational Criminal Organization. The Prince Group was identified as a major player in Cambodia’s scam economy, responsible for billions in illicit financial flows.

The most recent action, on April 23, 2026, went after Cambodian Senator Kok An along with 28 associated individuals and entities. That round resulted in $700 million in restrained digital assets and the seizure of 503 scam domains.

These actions were coordinated through the interagency Scam Center Strike Force, which has combined OFAC designations with asset restraints, domain seizures, and criminal charges.

The mechanics of pig butchering

The scams in question are commonly referred to as “pig butchering” schemes, where scammers cultivate relationships with victims over weeks or months, building trust before steering them toward fraudulent digital asset investment platforms.

The Treasury has highlighted that many of these scam centers rely on forced labor and human trafficking. Workers are lured to compounds in Cambodia, Myanmar, and other parts of Southeast Asia with promises of legitimate jobs, then coerced into running scam operations.

The criminal enterprises behind these operations are embedded in broader business networks that include casinos, holding companies, and real estate firms. The Prince Group, for example, operates across multiple sectors in Cambodia, and scam revenue gets laundered through seemingly legitimate commercial activity.

What this means for crypto investors

Secretary Bessent has stated that combating fraud remains a top priority for the Trump Administration.

The 66% year-over-year increase in losses suggests these scam networks were scaling faster than enforcement could keep up. Cambodia’s willingness to tolerate a sitting senator running scam centers suggests that local enforcement remains inconsistent.
