Definition
In AML contexts, a Blocked Person is any person or entity subject to asset-blocking measures under sanctions regimes, where financial institutions must immediately freeze funds, securities, or property in which the Blocked Person has an interest. This prohibition extends to direct or indirect dealings, ensuring no funds or assets are transferred without regulatory authorization. Unlike general high-risk clients, interaction with Blocked Persons triggers an absolute “no-deal” policy.
Key Characteristics
Blocked Persons are typically listed on official sanctions databases such as the U.S. Office of Foreign Assets Control (OFAC) Specially Designated Nationals (SDN) List, UN Security Council lists, or EU consolidated lists. Designation often stems from involvement in money laundering, terrorism support, weapons proliferation, or narcotics trafficking. Assets remain blocked—held in interest-bearing accounts—until delisting or license approval.
Purpose and Regulatory Basis
Role in AML Compliance
The designation of Blocked Persons disrupts illicit finance by isolating bad actors from the global financial system, preventing money laundering proceeds from being legitimized. It protects financial integrity, national security, and economic stability by deterring sanctions evasion. For institutions, it enforces due diligence, reducing exposure to criminal networks.
Key Global and National Regulations
The Financial Action Task Force (FATF) Recommendations (e.g., Recommendation 6) mandate asset freezing without prior notice for terrorism financing and proliferation risks, forming the global standard. In the U.S., the USA PATRIOT Act (Sections 311/312) and International Emergency Economic Powers Act (IEEPA) empower OFAC to block assets linked to designated persons. EU AML Directives (AMLD 5/6) require real-time screening against EU, UN, and national lists, with similar obligations in the UK under the Money Laundering Regulations 2017.
When and How it Applies
Triggers for Designation
Blocking applies when screening matches a customer, beneficial owner, or transaction against sanctions lists, including via the OFAC 50% Ownership Rule—where entities owned 50% or more by Blocked Persons are themselves blocked. Real-world triggers include wire transfers from SDN-listed entities or account openings with matching identifiers.
Real-World Use Cases and Examples
A bank receives a payment from a client whose subsidiary is 60% owned by an SDN-listed individual; the entire transaction must be blocked. In cryptocurrency, exchanges freeze wallets linked to sanctioned addresses. During Russia-Ukraine sanctions post-2022, numerous Russian oligarchs and banks became Blocked Persons, freezing billions in assets globally.
Types or Variants
Primary Classifications
- Specially Designated Nationals (SDNs): OFAC’s core list for comprehensive blocking, including terrorists and narcotics kingpins.
- Specially Designated Global Terrorists (SDGTs): Terrorism-focused subset with UN alignment.
- Blocked Entities via Ownership: Under the 50% Rule, non-listed companies controlled by Blocked Persons.
- Sectoral Sanctions (SSI): Limited restrictions, e.g., U.S. SSIs on Russian energy firms, versus full blocks.
Examples of Variants
EU “freeze lists” distinguish between asset freezes and travel bans, while UN 1267/1989 lists target Al-Qaida/Taliban affiliates.
Procedures and Implementation
Compliance Steps for Institutions
- Deploy automated sanctions screening software integrated into CDD, transaction monitoring, and payment systems.
- Upon match, block assets immediately—do not return funds or proceed—and notify senior management.
- File blocking reports: OFAC requires initial reports within 10 days, annual updates by September 30 for held property.
- Maintain segregated blocked accounts; seek OFAC licenses for limited releases if applicable.
Systems and Controls
Institutions must calibrate screening for false positives using fuzzy logic and maintain audit trails. Training ensures staff recognize indirect interests, like joint accounts.
Impact on Customers/Clients
Rights and Restrictions
Customers linked to Blocked Persons face frozen accounts, rejected transactions, and potential U.S. entry bans or green card ineligibility. They retain rights to challenge designations administratively or judicially, but institutions cannot unfreeze without authorization. Notification occurs post-blocking to prevent dissipation.
Client Interactions
Ongoing relationships halt; institutions provide status updates but decline new business. Clients may apply for delisting via petition processes.
Duration, Review, and Resolution
Timeframes and Ongoing Obligations
Blocks persist indefinitely until delisting, with no fixed duration. Institutions hold assets “in perpetuity” unless licensed. Annual reporting to OFAC covers June 30 balances.
Review Processes
OFAC conducts periodic list reviews; targets can submit delisting requests with evidence. Institutions re-screen regularly for changes.
Reporting and Compliance Duties
Institutional Responsibilities
Report blocks to regulators (e.g., OFAC Block Report Form), retain records for the block’s duration plus 5 years, and document screening efforts. Penalties for non-compliance include fines up to $1M per violation, criminal charges, and reputational harm.
Documentation Essentials
Logs of matches, decisions, and communications form the compliance backbone, supporting audits by FinCEN or equivalents.
Related AML Terms
Blocked Person status intersects with:
- Sanctions Screening: Initial detection tool.
- Payment Blocking: Transaction-specific freezes.
- Know Your Customer (KYC)/CDD: Identifies beneficial owners.
- Suspicious Activity Reports (SARs): Filed alongside blocks for laundering suspicions.
- Designated Persons: Broader term encompassing Blocked Persons.
This linkage ensures holistic AML programs.
Challenges and Best Practices
Common Issues
False positives overwhelm operations; complex ownership structures evade basic screening; crypto anonymity complicates identification. Legacy systems lag real-time monitoring.
Mitigation Strategies
Adopt AI-driven screening with name variants and blockchain analytics. Conduct periodic enhanced due diligence (EDD) on high-risk jurisdictions. Partner with legal experts for license applications and staff training via scenario-based simulations.
Recent Developments
As of April 2026, the U.S. GENIUS Act mandates AML/CFT compliance for payment stablecoin issuers, requiring token freezes for Blocked Persons—even in non-custodial wallets—and annual certifications. FATF’s 2025 updates emphasize virtual asset screening. EU AMLR (effective 2027) strengthens real-time blocking with centralized access to sanctions data.
