U.S. and U.K. law-enforcement agencies have established a joint framework to investigate transnational cryptocurrency and cyber-enabled investment scam networks, which authorities say cost Americans nearly $10 billion annually. The U.S. Attorney's Office for the District of Columbia, the Crown Prosecution Service of England and Wales and the U.K. National Crime Agency will investigate shared targets in parallel, exchange intelligence on organized crime groups and determine where common cases should be brought. FBI findings put total reported internet-crime losses at $20.88 billion in 2025, including $11.37 billion linked to cryptocurrency and about $7.2 billion from cryptocurrency investment fraud. The agreement builds on the U.S. Scam Center Strike Force and broader efforts to freeze assets, disrupt online accounts and pursue networks operating scam compounds, particularly in Southeast Asia. The National Crime Agency will host U.S., U.K. and private-sector partners at a disruption event in London in early October.
