Roughly $141 billion in stablecoins flowed to illicit actors in 2025, with sanctions-linked networks — including a ruble-pegged token tied to Russian operations — accounting for the vast majority of detected transfers, according to blockchain analytics firms TRM Labs and Chainalysis.
What Happened: Sanctions-Tied Transfers
TRM Labs reported that sanctions-related flows made up approximately 86% of all detected illicit cryptocurrency transfers last year. Of the stablecoin total, around $72 billion traced back to a ruble-pegged token connected to Russian networks.
Those networks showed overlaps with entities linked to China, Iran, North Korea, and Venezuela.
Stablecoins served as bridges between different sanctioned systems because their price stability allows predictable settlement with minimal volatility risk.
Separately, escrow and guarantee marketplaces — platforms that act as intermediaries for high-value transfers — saw tens of billions of dollars move through their systems, almost entirely in stablecoins. Chainalysis identified sharp increases in flows to networks connected to human trafficking and escort services, with those operations relying on stablecoins for payment certainty.
Scams, ransomware, and thefts often start in Bitcoin (BTC) or Ether (ETH) before shifting into stablecoins later in the laundering chain. Attackers favor assets that hold value as funds move through fewer intermediaries.

Why It Matters: Market Scale Context
The $141 billion figure lands against a stablecoin sector that has grown into a roughly $270 billion market as of early 2026, according to Stablecoin.com data.
Two issuers dominate. Tether's USDT (USDT) leads with a market cap frequently reported above $180 billion, representing more than two-thirds of total stablecoin capitalization. Circle's USD Coin (USDC) holds second place above $70 billion — together the two account for over 90% of the market.
Smaller tokens including Ethena USDe (USDe), DAI (DAI), and PayPal USD (PYUSD) represent a much smaller share but signal ongoing diversification among stablecoin providers, the data tracker noted.
