How Geopolitical Sanctions are Changing the Role of Crypto in Cross-Border Payments

Economic sanctions were designed around a financial system dominated by banks, correspondent accounts and identifiable intermediaries. Stablecoins and blockchain networks are complicating that model by allowing value to move internationally without relying on the same infrastructure.

That does not make crypto transactions invisible. Instead, it is creating a parallel contest between governments trying to enforce sanctions and state-linked actors searching for alternative settlement rails.

Sanctions-Related Crypto Activity has Surged

Chainalysis estimates that sanctioned entities received about USD 104 billion in cryptocurrency in 2025, representing a 694% year-over-year increase. Total value received by identified illicit crypto addresses reached at least USD 154 billion, although illegal activity remained below 1% of attributed crypto transaction volume overall.

Stablecoins accounted for approximately 84% of identified illicit transaction volume, reflecting the same characteristics that make them useful for legitimate cross-border payments: relatively stable prices, 24/7 settlement and international transferability.

Russia provides one example. The ruble-backed A7A5 stablecoin processed about USD 93.3 billion within 10 months, according to Chainalysis, as businesses searched for ways to transact outside conventional banking channels.

Iran Shows Both the Opportunity and the Limits

Crypto has also become increasingly relevant to Iran as international financial restrictions tighten. Chainalysis estimates Iran's crypto ecosystem received around USD 7.78 billion in 2025, while networks linked to the Islamic Revolutionary Guard Corps accounted for more than USD 3 billion. Yet blockchain transactions can be traced and assets can still be frozen when centralized issuers are involved.

In July, the US Office of Foreign Assets Control added four crypto addresses associated with Iran's central bank to its designation. Those wallets had received around USD 165 million in stablecoins, and Tether subsequently froze approximately USD 131 million. The Treasury followed with additional sanctions against Iranian digital-asset exchanges in August.

Governments are Adapting Their Sanctions Tools

Enforcement is becoming increasingly blockchain-specific. The European Union's 21st Russia sanctions package imposed transaction restrictions on 14 crypto-related platforms across six jurisdictions and introduced mechanisms targeting third-country crypto providers used for sanctions circumvention.

The result is a shift from sanctioning bank accounts alone to monitoring exchanges, wallet addresses, stablecoins and digital-asset service providers.

Crypto is Becoming Geopolitical Financial Infrastructure

Stablecoins can lower friction for legitimate remittances and international commerce, but the same infrastructure can also support sanctioned trade.

That dual use is likely to shape future regulation. Crypto's role in cross-border payments may therefore expand alongside, rather than outside, financial surveillance as governments bring blockchain activity deeper into sanctions enforcement.
