FATF Warns Stablecoins Dominate Illicit Crypto Transactions, Urges Stronger AML Oversight

The Financial Action Task Force (FATF) has intensified its scrutiny of stablecoins, warning that dollar-pegged digital assets have become the primary vehicle for illicit cryptocurrency transactions. In a 42-page report released Tuesday, the global anti-money laundering watchdog stated that stablecoins are now the most widely used virtual assets in illegal finance, including transactions linked to Iran and North Korea.

According to the FATF, stablecoins accounted for the majority of illicit on-chain activity in recent years. In January 2026, the organization estimated that fraud and scam-related activity involving stablecoins reached approximately $51 billion in 2024. Its March 2026 report reinforced these concerns, citing data from blockchain analytics firm Chainalysis showing that stablecoins represented 84% of the $154 billion in illicit virtual asset transaction volume in 2025.

The report highlighted the growing use of tokens such as Tether (USDT) in proliferation financing and cross-border payments tied to sanctioned entities. North Korean and Iranian actors were specifically identified as leveraging stablecoin platforms to move funds and bypass traditional financial restrictions.

Research from TRM Labs further underscores the scale of the issue. The firm reported that illicit entities received $141 billion in stablecoins in 2025, marking the highest level recorded in five years. Overall stablecoin transaction activity surpassed $1 trillion per month multiple times last year. Notably, sanctions-related activity accounted for 86% of illicit crypto flows, with bad actors predominantly relying on stablecoin infrastructure.

The FATF emphasized that peer-to-peer transfers through unhosted wallets pose a significant vulnerability, as these transactions can occur without robust anti-money laundering controls. While stopping short of recommending blanket blacklisting, the watchdog called on regulators to impose stricter AML requirements on stablecoin issuers. It also suggested implementing wallet-freezing mechanisms and restricting certain smart contract functions to mitigate risks.

With the stablecoin market now exceeding $300 billion in market capitalization, the FATF warned that regulators must act swiftly to close compliance gaps as adoption accelerates across the global digital asset ecosystem.
