What is the difference between transaction screening and transaction monitoring?
Transaction screening involves checking transactions against sanction lists to ensure compliance with AML regulations before processing.
Transaction monitoring is a continuous process that detects suspicious or unusual behavior, potentially indicating financial crime, by monitoring processed transactions.
Both transaction screening and transaction monitoring are key components of financial crime prevention, especially in anti-money laundering (AML) and fraud detection systems. However, they serve different purposes and operate in distinct ways:
| Aspect | Transaction Screening | Transaction Monitoring |
|---|---|---|
| Definition | The process of checking customers, entities, and transactions against sanctions lists to identify and block prohibited activities. | The continuous monitoring of financial transactions to detect suspicious or unusual behavior that may indicate financial crime. |
| Objective | To ensure compliance with sanctions regulations by preventing dealings with sanctioned individuals, entities, or countries. | To detect and prevent financial crimes such as money laundering, fraud, and terrorist financing. |
| Scope | Focuses on screening names, organizations, and jurisdictions against global sanction lists (e.g., OFAC, UN, EU, UK, etc.) or other applicable watchlists. | Monitors customers’ transactions in real-time or retrospectively to identify unusual activity patterns. |
| Key Data Sources | Sanctions lists, Politically Exposed Persons (PEP) lists, adverse media databases, internal and 3rd -party watchlists, industry-specific regulatory sources. | Customer transaction history, behavioral patterns, risk profiles, account usage data, geographic and jurisdictional risk indicators, thresholds for suspicious activities. |
| When It Happens | Screening transactions in real-time, upon customer onboarding (Know Your Customer – KYC), and periodically as sanctions lists are updated. | Continuously throughout the customer relationship, tracking transactions in real-time or batch processing. |
| Technology Used | Name matching algorithms, fuzzy logic, and artificial intelligence (AI) to detect similarities and prevent false positives. | Machine learning, rule-based analytics, and AI-driven pattern recognition to detect anomalies. |
| Regulatory Focus | Mandated by regulatory requirements to prevent transactions with sanctioned individuals or organizations. | Compliance with AML regulations and fraud detection. |
| Examples of Use Cases | Blocking a transaction involving a person on the OFAC list or other sanction or watchlist; rejecting a new account opening if the applicant is on a sanctions list. | Detecting an account with an unusual number of high-value cash deposits; identifying structured transactions indicative of money laundering. |
Key Takeaways
- Transaction Screening prevents financial institutions from engaging with sanctioned entities and is primarily an AML compliance function.
- Transaction Monitoring ensures ongoing surveillance of financial activities to detect suspicious behaviours related to money laundering and other illicit activities.
Both processes work together to protect financial institutions from regulatory risks and financial crime exposure.
