Transnational criminal networks based in Southeast Asia stole between $88.3 billion and $114.1 billion from victims across the Asia-Pacific region in 2025, according to a threat assessment released this week by the United Nations Office on Drugs and Crime (UNODC). A significant portion of those funds moved through cryptocurrencies, and the agency warned that the scale of the criminal economy is now outpacing law enforcement efforts.

The UNODC report, published Tuesday, marks a dramatic escalation from the UN's previous estimates. The 2025 figure is at least three times higher than the $18 billion to $37 billion range estimated for 2023. The report attributed the surge to "the dramatic scaling of this criminal economy." The findings arrive as governments across the Asia-Pacific region have been tightening virtual asset regulations, including licensing regimes for crypto service providers and phased implementation of the Financial Action Task Force's Travel Rule, which requires intermediaries to share sender and recipient information for qualifying transactions.

Syndicates Evolve into Integrated Transnational Networks

UNODC describes a structural shift in the region's criminal landscape. Syndicates that once operated within single territories and specialized in single crime types have consolidated into an interconnected transnational network. Groups now sell services to one another through shared infrastructure, with money laundering, fraud, human trafficking, and data harvesting functioning as specialized divisions within the same system.

Delphine Schantz, UNODC regional representative for Southeast Asia and the Pacific, compared the arrangement to "corporate franchising" in a statement accompanying the report.

The aggregate losses "outstrip the GDP of several countries in the region," the report noted, characterizing the criminal economy as an integrated industry rather than a loose collection of gangs.

China, South Korea, and Taiwan have each reported billions in losses over the past two years. While syndicates previously targeted primarily Chinese-speaking audiences, their reach has since expanded. AI-powered translation tools have enabled operators to pitch to new demographics, and recruiters continue to seek staff fluent in English, German, Polish, Dutch, Spanish, Italian, French, Swedish, and Norwegian. Individuals from at least 80 countries and territories have been identified inside compounds across the Mekong region.

Compounds in Cambodia and Myanmar Outlast Raids and Sanctions

The operations maintain a regional base in Cambodia and Myanmar, where fortified compounds house both willing and trafficked workers who conduct fake romance schemes and fraudulent crypto investment operations—a method commonly known as "pig butchering." Proceeds are then laundered through blockchain-based mechanisms. The UNODC findings echo advisories issued over the past two years by the U.S. Treasury, the UK's National Crime Agency, and Europol, all of which have flagged Southeast Asia as a hub for crypto-enabled fraud targeting victims in Europe and North America.

UNODC situates these scam centers within a broader criminal ecosystem that also encompasses methamphetamine trafficking, child sexual exploitation, and real estate investment. These activities flow through established trade channels and are concealed behind cryptocurrencies, according to the report.

The agency delivered a blunt assessment to law enforcement: raids alone are insufficient. Although alleged kingpins have been arrested and extradited—including several network bosses transferred from Cambodia to China over the past year, following sanctions imposed by Washington and London on linked firms and individuals—many operational centers have continued uninterrupted.

Schantz warned of the blurred line between trafficked victims and individuals who acquire criminal skills inside the compounds. Some return to their home countries and connect with existing criminal networks in Africa and the Balkans, further propagating the model.

UNODC urged regional police forces to undergo specialized cryptocurrency training to improve their ability to track and seize on-chain proceeds. The recommendation underscores a capability gap documented across the region: while blockchain analytics firms such as Chainalysis and TRM Labs have expanded their coverage of Southeast Asian illicit activity, many national police units still lack dedicated crypto-investigation teams.

INTERPOL's Operation First Light 2026, conducted across 97 countries from January through April, resulted in 5,811 arrests and the freezing of $293 million. In one notable case, a 20-year-old suspect in Thailand moved over $122.5 million in romance scam proceeds through a single wallet within ten months, laundering the funds via cross-chain token swaps to obscure the transaction trail across blockchains. Cross-chain bridges allow assets to move between separate networks, breaking the contiguous transaction history that investigators depend on to follow funds from origin to cash-out point.
