Stablecoins have become the primary means for illegal money flows, especially for entities under embargo that need liquid, dollar-pegged instruments for cross-border transactions.
The rise in criminal transactions using cryptocurrency has coincided with the increasing use of stablecoins in 2025. Coingecko recorded a 48.9% surge in stablecoin market capitalization, reaching a new high of $311 billion in 2025.

Geopolitical Pressures
The second factor driving the increase in illegal crypto-linked transactions is geopolitical pressure, which encouraged state actors to use crypto as core financial infrastructure rather than as a last resort. In other words, crypto is being institutionalized by various state actors subject to US sanctions.
For example, Venezuela uses crypto to support domestic and international payments and other state financial activities.
Meanwhile, in China, crypto volume increased from $123 million in 2020 to $103 billion in 2025, in line with the rise of escrow services and underground banking networks.
Conclusion
As crypto adoption expands, its use for illegal activities is also increasing. The actors are no longer just individuals or organizations, but players in the state level. Cryptocurrency is not just a transaction or investment tool, but a tool for building a shadow economy that runs parallel to the economy we see every day.
