The Riffle
The global stablecoin market has grown rapidly, with over 250 stablecoins in circulation and a market capitalization exceeding USD 300 billion. While stablecoins support faster payments and improved liquidity, they are increasingly being used in illicit financial activities.
In 2025, stablecoins accounted for approximately 84% of illicit virtual asset transaction volumes, reflecting their growing role in financial crime. A key vulnerability lies in peer-to-peer (P2P) transfers conducted through unhosted wallets, where transactions occur without AML/CFT-regulated intermediaries.
Key Highlights
1. Stablecoin Market Dominance
Fiat-backed stablecoins represent around 95% of total stablecoin market capitalization.
Stablecoins now account for about 30% of on-chain transaction volume.
Financial institutions and payment providers are increasingly integrating stablecoins for cross-border payments and settlements.
2. Illicit Use Cases
Stablecoins are increasingly used for:
Money laundering and fraud, including romance scams and investment fraud
Drug trafficking payments and laundering through OTC brokers
Proliferation financing, including activity linked to DPRK cyber groups
Terrorist financing, where donations are collected via encrypted platforms.
Criminal actors often rely on chain-hopping, micro-splitting, and cross-chain transactions to obscure fund flows.
3. Risks from Unhosted Wallets
Unhosted wallets allow users to transact directly without regulated intermediaries.
Key risks include:
Pseudonymous blockchain transactions that obscure user identities
Rapid creation of new wallet addresses to avoid detection
Multi-layer wallet structures distancing funds from regulated entities.
These features make P2P stablecoin transfers particularly difficult to monitor or control.
4. Emerging Mitigation Practices
Regulators and issuers are exploring new tools to manage risks:
Allow-listing: restricting transfers to verified wallet addresses
Deny-listing: blocking addresses linked to illicit activity
Freeze or burn mechanisms: enabling issuers to immobilize funds when required by authorities.
Blockchain analytics tools are also increasingly used to track suspicious activity and identify high-risk wallets.
Why It Matters
As stablecoins become increasingly embedded within global payment infrastructure, the line between crypto markets and traditional finance continues to blur.
Regulators are therefore focusing on ensuring that stablecoins do not become a systemic channel for financial crime.
For jurisdictions and market participants, this means:
Implementing robust AML/CFT frameworks aligned with FATF Recommendation 15
Enhancing monitoring of P2P transactions involving unhosted wallets
Deploying blockchain analytics and sanctions screening tools
Strengthening international cooperation across supervisory authorities.
Conclusion
Stablecoins offer significant opportunities for faster payments, improved liquidity, and financial innovation. However, their rapid adoption has also introduced new risks, particularly when transactions occur outside regulated intermediaries.
Addressing these challenges will require coordinated regulatory oversight, technological innovation, and proactive monitoring by both the public and private sectors. As jurisdictions refine their approaches, stablecoin governance will remain a critical focus area in the global fight against financial crime.
