What You Need to Know about Anti-Money Laundering Enforcement and National Security

The Bank Secrecy Act requires financial institutions to file Suspicious Activity Reports (SARs) when they detect transactions that may involve money laundering or sanctions evasion. OFAC administers sanctions programs that prohibit transactions with designated individuals, entities, and countries. FinCEN enforces anti-money laundering rules and coordinates with law enforcement. Anti-Money Laundering compliance obligations extend beyond financial institutions to certain non-financial businesses and professions, including attorneys, accountants, and real estate professionals in high-risk transactions. The penalties for violations range from civil fines to criminal prosecution, with individual officers and the corporation itself facing exposure.

CFIUS and CFIUS & US National Security screening mechanisms evaluate whether foreign investment threatens critical infrastructure, sensitive technology, or national defense capabilities. Unlike AML enforcement, which responds to detected suspicious activity, national security review often operates prospectively, requiring advance notification and approval before a transaction closes. Courts have upheld broad CFIUS authority to block or condition transactions based on classified intelligence and threat assessments. A corporation cannot rely on the absence of criminal intent or AML compliance to satisfy national security concerns; the standard focuses on whether the transaction poses strategic risk, regardless of the foreign party's financial or legal status.

An effective AML compliance program includes customer due diligence (CDD), enhanced due diligence (EDD) for higher-risk customers, ongoing transaction monitoring, independent auditing, and staff training. Corporations must identify beneficial owners of customer entities, verify customer information against government watchlists, and document the basis for customer acceptance. Monitoring systems must flag transactions that deviate from customer profiles or involve high-risk jurisdictions. When monitoring detects suspicious patterns, the corporation must decide whether to file a SAR or continue monitoring; this decision is often contested in enforcement proceedings because the timing and content of SARs create evidence trails that regulators and prosecutors later use to establish knowledge and intent.

Failure to file a SAR when the corporation knew or should have known of suspicious activity constitutes a violation of the Bank Secrecy Act. FinCEN can impose civil penalties ranging from thousands to millions of dollars per violation. Criminal prosecution is possible if the failure was willful. In practice, enforcement actions often turn on whether the corporation's monitoring systems were adequate and whether decision-makers documented their reasoning for reporting or not reporting. A New York federal district court may examine whether the corporation's internal procedures created accountability for AML decisions and whether training records demonstrate that compliance personnel understood reporting obligations; delays in implementing monitoring upgrades or gaps in documentation of SAR decisions can shift liability exposure significantly.

OFAC maintains lists of sanctioned entities and individuals, and corporations must screen customers, counterparties, and beneficial owners against these lists. Transacting with a sanctioned party, even unknowingly, violates OFAC regulations. The intersection with national security occurs because many sanctioned entities are designated precisely because of their links to hostile foreign governments or terrorist organizations. A corporation's failure to detect a sanctioned party in a transaction can be characterized as either an AML compliance failure or a national security concern, depending on the government agency leading the investigation.

Corporations should conduct a comprehensive audit of existing compliance programs to identify gaps in customer due diligence, transaction monitoring, and SAR decision documentation. Review beneficial ownership records for all material customers and counterparties to ensure accuracy and completeness. Establish a clear escalation protocol for transactions involving high-risk jurisdictions or politically exposed persons. Document the basis for customer acceptance decisions and the rationale for transaction monitoring thresholds. Create a record-keeping system that preserves evidence of compliance decisions and the timing of any concerns identified. For transactions involving foreign investment or cross-border payments, obtain CFIUS guidance or OFAC licenses before proceeding if the transaction involves a sensitive sector or a party from a higher-risk jurisdiction. These steps create a defensible record if government investigators later examine the corporation's conduct and help ensure that compliance decisions are grounded in documented risk assessment rather than ad hoc judgment.

Upon receiving a subpoena or investigative demand, a corporation should immediately notify its compliance officer, general counsel, and external counsel. Do not destroy or alter documents. Request an extension if the timeline is unreasonable. Identify privileged communications and withhold them on the basis of attorney-client privilege or work product doctrine. Coordinate responses across departments to ensure consistency and accuracy. In some cases, the corporation may request a meet-and-confer with government investigators to clarify the scope of the investigation and negotiate a manageable production schedule. Proactive engagement and transparent cooperation, supported by thorough documentation of the corporation's compliance efforts, can influence how investigators characterize the corporation's conduct and the ultimate enforcement decision.
