Anti-Money Laundering & Economic Sanctions

Anti-money laundering (AML) and sanctions are top U.S. and global enforcement priorities. The failure to meet increasingly complex expectations can result in investigations, billion-dollar fines and reputational damage. Our team provides sophisticated AML and sanctions counsel to banks, fintechs, digital asset companies and other multinational clients.

Deep Government Experience

Our team is our primary value proposition. We formulated and enforced AML and sanctions policies while serving in key government posts, enabling us to provide unique insights and strong regulatory relationships.

Our team includes:

  • The former U.S. Treasury deputy general counsel responsible for overseeing the legal offices of the Financial Crimes Enforcement Network (FinCEN) and Office of Foreign Assets Control (OFAC), as well as a former Treasury senior advisor for AML and sanctions issues.
  • The former deputy head of enforcement at FinCEN, as well as a former OFAC enforcement officer.
  • The former principal deputy chief of DOJ’s Money Laundering and Asset Recovery Section (MLARS, now MNF), which is responsible for AML/sanctions investigations of financial institutions.
  • The former principal deputy assistant attorney general of DOJ’s Criminal Division.
  • Former counsel at the Office of the Comptroller of the Currency (OCC), the Federal Reserve Board, the New York State Department of Financial Services (NY DFS) and other financial regulators.

Our team also includes experienced lawyers in the U.K., the EU and Asia, allowing us to provide multijurisdictional advice and defense. We work seamlessly with our export controls, bank regulatory, fintech and consumer protection teams, as well as our broader white collar defense practice.

Regulatory Advice and Compliance Counseling

Our primary objective is to help clients avoid unwanted regulatory attention. To this end, we assist with risk assessments and compliance upgrades and partner with clients to anticipate, interpret and implement rapidly evolving regulatory expectations. We have helped, for example, clients plan for imminent regulatory changes (including FinCEN’s proposed program and stablecoin rules), address government priorities (including around cartels, trade-based money laundering and the growing focus on fraud) and integrate AI into compliance processes. We also advise on correspondent banking, KYC/CIP/CDD implementation issues, the Travel Rule, SAR-filing decisions and other areas that continue to pose risk.

We have also helped clients adapt to the growing number of Foreign Terrorist Organization (FTO) designations and OFAC’s evolving approaches to Iran, China, Russia, Venezuela and Cuba. We have extensive experience counseling on sanctions compliance for digital assets. We also have a strong track record of obtaining novel OFAC licenses and submitting voluntary disclosures that result in no penalty.

Examinations and Investigations

In examinations, we are adept at reducing adverse findings and avoiding escalations to enforcement. When the government initiates an investigation, we are tireless, creative and efficient at delivering the best results possible for our clients. Our team has successfully handled some of the largest criminal and regulatory enforcement matters in this space. We have represented clients in AML and sanctions matters before the DOJ (including various U.S. Attorneys’ Offices), Treasury (FinCEN and OFAC), federal banking agencies (including the OCC, Federal Reserve and FDIC), congressional committees and state authorities such as the New York Department of Financial Services (NY DFS) and California Department of Financial Protection and Innovation (CA DFPI). We have also handled investigations internationally before the U.K. Financial Conduct Authority (FCA), U.K. Serious Fraud Office (SFO) and U.K. Office of Financial Sanctions Implementation (OFSI), among others. We have also represented clients in parallel civil lawsuits involving AML and sanctions matters, including under the Anti-Terrorism Act.
