What is transaction screening?

Payment screening, also known as transaction screening, is the critical process of verifying the information attached to a payment to ensure it does not present red flags for financial crime. Payment screening is conducted before a payment is processed and focuses on combatting payments to illicit actors on predefined watchlists and sanctions lists, or specific criteria such as dual-use or prohibited goods lists.

Which regulations require transaction screening?

In adherence to global, regional, and industry-specific sanctions regulations, organizations are expressly forbidden from facilitating transactions involving individuals, entities, or countries subjected to sanctions within their operating jurisdiction.  

Sanctions regulations 

It is paramount for organizations to implement rigorous procedures for scrutinizing the sanction status of all transaction parties prior to approval. With geopolitical instability, rising sanctions activity, and constantly changing regulations, organizations must continuously update sanctions lists and customize watchlists for different jurisdictions. Regulatory bodies, such as OFAC, emphasize a risk-based approach to sanctions compliance for instant payments, pushing firms to modernize screening workflows. By leveraging a robust transaction screening solution, they can effectively identify, and screen all involved parties against the relevant sanctions lists, thereby remaining in compliance with regulatory requirements. 

AML and CTF regulations 

Compliance with AML and Counter-Terrorist Financing (CTF) regulations mandates that organizations diligently investigate and report suspicious activities indicative of potential money laundering and terrorist financing risks. To meet this obligation, organizations must establish robust procedures for scrutinizing transaction attributes and seek out red flags that warrant further investigation. Through the use of transaction screening software, they can proficiently flag high-risk countries and currencies, dual-use goods, and instances of wire stripping. As a result, organizations can reinforce their ability to pinpoint suspicious activity, thus ensuring strict compliance with AML and CTF regulations. 

Which organizations should conduct transaction screening?

Because regulations vary by country, industries that are more prone to money laundering and terrorist financing may have additional compliance requirements. Here are some of the types of organizations that are obligated to implement a robust transaction screening program in the US, according to the Electronic Code of Federal Regulations: 

• Banks and Financial Services: Commercial banks, investment banks, credit unions, brokerage firms, operators of credit card systems, and loan or finance companies 

• Money Services Businesses (MSBs): Hedge funds and private equity firms, including fintechs that are payment service providers, and cryptocurrency exchanges 

• Insurance Companies: Insurance providers, especially those dealing with high-risk products like cash value life insurance and annuities 

• Securities and Investment Firms: Stock exchanges, securities brokers and dealers, investment advisors, and mutual funds 

• Precious Metals Dealers: Businesses involved in buying and selling high-value items susceptible to money laundering 

• Casinos and Gaming Industry: Casinos and gaming establishments that handle large cash transactions 

And depending on the jurisdiction and regulations, other industries are typically expected to implement a transaction screening program. These include:

• Non-Profit Organizations: Charities and endowments, particularly those involved in internationally funded donations and donors 

• Exporters and Importers: Companies engaged in international trade, as cross-border transactions may pose higher AML risks as well as risks through dual-use commodities 

• Legal and Accounting Firms: Professional service providers dealing with financial transactions and client funds 

• Real Estate Sector: Real estate brokers and agents involved in high-value transactions 

Real-time vs. batch processing

When it comes to transaction screening, the choice between real-time screening and batch processing hinges on the urgency of your transactions. The cardinal rule is to ensure that every transaction undergoes screening, and that any potential alerts are thoroughly reviewed before authorizing the transaction’s release. 

For time-sensitive transactions, opting for real-time screening through an API, as offered by FinScan Payments, is often the preferred route. This allows for instantaneous screening and, if no alerts are raised, the transaction can be promptly released. This method is particularly well-suited for scenarios such as card payments, where swiftness speed is crucial to the customer experience. 

On the other hand, batch processing entails screening a group of transactions, typically at a specified time, before their collective release. This approach is apt for sectors like insurance, where the time sensitivity of payments may be less acute than card transactions, making batch processing a more pragmatic and workload-efficient choice. 

Five main challenges in transaction screening

While vital for AML compliance, transaction screening is not without its challenges. Organizations face key hurdles which underscore the complexity and critical nature of effective transaction screening in safeguarding financial integrity. Here are the five main challenges organizations encounter in transaction screening: 

1. False positives 

False positives, in which legitimate transactions are erroneously flagged as suspicious, present a formidable challenge. Not only do they consume valuable resources, but they also divert the attention of your team away from genuine risks. This inefficiency can lead to operational bottlenecks that could compromise the efficacy of your compliance efforts while also hampering customer experience as their payments get delayed. Smarter, risk-based transaction screening approaches are essential to maintaining speed without compromising security 

2. False negatives 

Conversely, false negatives represent a significant risk. They occur when potentially illicit activity goes undetected, undermining the very essence of AML efforts. This leaves organizations vulnerable to compliance breaches and exposes them to the potential for reputational damage and penalties. It is imperative to fortify transaction screening processes to reduce false negatives. 

3. Managing high transaction volumes 

Ensuring your transaction screening AML solution can seamlessly handle large daily transaction volumes, potentially in the millions and without compromising on reliability, is crucial. However, many traditional AML compliance systems were built for slower settlement cycles and struggle to keep pace with real-time transaction processing.  

4. Response time 

In the realm of compliance, speed is essential. Instant payments create a narrower window for transaction screening and risk assessment, requiring millisecond-level compliance checks. Timely responses are crucial to prevent the escalation of risks and maintain adherence to regulatory requirements. Swift action ensures that opportunities for intervention are not missed, safeguarding the integrity of your AML compliance program. 

5. SWIFT integration 

In the case of international transactions, seamless integration with the SWIFT network is fundamental for ensuring secure and expedient transaction processing. This integration is pivotal in preventing delays or errors in screening, thereby maintaining operational continuity. In addition, the adoption of ISO 20022 messaging standards and cross-border payment systems means compliance teams must adapt to evolving transaction formats and workflows. 

The transformative power of transaction screening

Transaction screening AML represents a cornerstone of modern financial compliance, playing a pivotal role in safeguarding the integrity of financial systems worldwide. Transaction screening spans a diverse range of industries and is guided by stringent regulations aimed at preventing illicit financial activities. 

Despite its challenges, such as managing high volumes of transactions and avoiding false positives and negatives, effective transaction screening is vital for maintaining the trust and security essential in the financial sector. Advanced platforms like FinScan offer promising solutions to these challenges, ensuring that organizations can stay compliant and vigilant against financial crimes. As the financial landscape continues to evolve, transaction screening remains an indispensable tool, constantly adapting to meet new challenges and protect against emerging risks. 

Six steps to an effective transaction screening process

Implementing an effective transaction screening process is crucial for maintaining compliance and preventing financial crimes. Here are six essential steps to follow, from the initiation of a transaction to ongoing testing and refinement, to ensure a robust and efficient screening process. 

Step 1: Initiation of the transaction 

This involves the initiation of a financial transaction, during which relevant transaction details are provided. These details are then used to generate a standardized message format, such as SWIFT’s MT messages or ISO20022. The formatted message is transmitted through secure channels, ensuring the integrity and confidentiality of the data. 

Step 2: Transaction screening initiation 

Once the transaction message is received, the transaction screening process is triggered. Transaction screening software like FinScan, equipped with advanced screening algorithms and predefined rules, systematically examines the transaction details. This includes cross-checking transaction parties and elements against various watchlists and generating alerts against specific attributes such as name and address of the ordering entity and its beneficiaries, BIC code elements, currency types, dual-use goods, and countries. 

Step 3: Alert review and investigation 

In this step, a team of compliance analysts, led by a Money Laundering Reporting Officer (MLRO) or a compliance officer, takes over. They review and investigate the generated alerts. Integrated case management systems provide additional information for a thorough examination. The team assesses the validity of the flagged transaction and evaluates potential risks associated with it. 

Step 4: Blocking or releasing transactions 

Depending on the alert severity, the analyst remediates the alert by either blocking or releasing the alerted transaction. For more complex scenarios, the reviewer notifies the designated authority, typically through an escalation workflow provided in the platform’s case management tool. This transaction screening AML workflow allows analysts to execute the necessary actions, ensuring appropriate measures are taken to identify and stop potentially illicit activity, which is crucial in mitigating risks and maintaining compliance. 

Step 5: Documentation and reporting 

Every action taken in the transaction screening process is meticulously documented. Document management systems and reporting tools facilitate this process, creating a detailed record of the screening process and alert dispositions. These records are vital components of compliance reporting and serve as audit trails during internal or external inspections. 

Step 6: Ongoing testing 

The transaction screening process is not static. It requires regular testing and fine-tuning to ensure effectiveness over time. This step involves systematic assessments and checks to identify any areas for improvement or adjustment in the transaction screening AML procedures. Ongoing testing is crucial for staying ahead of evolving risks and compliance requirements. 

What’s the difference between transaction screening and transaction monitoring?

Transaction screening and transaction monitoring are not the same. Transaction screening is a pre-transaction process designed to identify and flag potentially suspicious transactions before they occur. In contrast, transaction monitoring is an ongoing post-transaction process focused on detecting unusual or suspicious patterns in transactional behavior. 

Transaction screening involves cross-checking transaction details, parties, and attributes against watchlists and predefined rules. The objective is to ensure that no transactions involve entities or individuals subject to sanctions or other regulatory restrictions. This process is crucial for preventing illicit activities like money laundering and terrorist financing. 

Transaction monitoring involves analyzing historical and real-time transaction data to identify potentially high-risk activities. The objective is to alert compliance teams to potentially suspicious transactions for further investigation, even after they have been executed. This helps in identifying and reporting any suspicious activities that may not have been flagged during the initial screening process.
