Who is liable when an exchange processes transactions for sanctioned entities?

Processing transactions for sanctioned parties can expose a virtual asset service provider to multiple layers of accountability. Guidance from the Office of Foreign Assets Control under Andrea M. Gacki, U.S. Department of the Treasury, clarifies that exchanges must prevent transactions that would circumvent sanctions programs; failure to do so risks regulatory and criminal liability. The Financial Action Task Force provides complementary standards that expect robust controls for virtual assets, and the Financial Crimes Enforcement Network, U.S. Department of the Treasury, has repeatedly emphasized transaction monitoring and suspicious activity reporting as baseline obligations.

Legal and regulatory liability

Regulators pursue both civil penalties and criminal charges depending on conduct. Under U.S. sanctions law, civil fines can result from apparent violations, while willful violations, where an exchange knowingly facilitates prohibited transactions, can trigger criminal prosecution and much higher penalties. Secondary sanctions may also apply, allowing authorities to penalize non-U.S. entities that materially support sanctioned parties. National licensing regimes and supervisory authorities in Europe, Asia, and elsewhere can revoke operating permits or impose administrative sanctions if compliance frameworks are deficient. These frameworks are grounded in FATF recommendations that prioritize customer due diligence, sanctions screening, and recordkeeping.

Operational, contractual, and social consequences

Beyond fines, an exchange faces operational disruption: frozen funds, loss of correspondent banking, and contract breaches with payment processors and custodians. For communities relying on remittances, overly broad blocking can have humanitarian consequences, prompting regulators to issue specific or general licenses to permit aid and permitted transactions while still enforcing sanctions. Reputation risk also has real economic effects; customers and partners may depart after public enforcement actions, reducing liquidity and market access.

Practical implications require exchanges to maintain end-to-end compliance: real-time sanctions screening, enhanced due diligence on high-risk jurisdictions, and documented policies demonstrating an intent to comply. Applying guidance from Andrea M. Gacki at the Office of Foreign Assets Control and from the Financial Action Task Force helps align controls with international norms. Ultimately, liability depends on jurisdiction, the exchange’s knowledge and intent, and the adequacy of its compliance program; robust, well-documented defenses substantially reduce legal exposure while protecting broader social and territorial interests.
