In 2024, the ACH (Automated Clearing House) Network experienced significant growth in both transaction volume and value. According to Nacha, 33.6 billion transactions with a total value of $86.2 trillion were processed. As the volume of ACH transactions continues to grow, it is becoming crucial for Financial Institutions to implement accurate and efficient automated OFAC screening to ensure their regulatory compliance.
Screening ACH payments for sanctions compliance can be easier said than done. Financial institutions face several common challenges that make effective ACH screening a complex task. Below are some of the major hurdles and pain points, along with insights on why they occur.
Summing up the challenges of ACH payments screening
High Volume, Low Data Density
- ACH files include multiple transaction records. These files are typically very large and contain multiple batches of thousands of transaction records.
- Unlike wires, ACH payments records carry minimal data, often just name and account number, with few unique identifiers like DOB or address.
- ACH payments detail records often contain unstructured, or misspelled names, which makes name matching against OFAC’s sanctions lists and other watchlists highly error-prone, resulting in high volume of false positives and increasing the chance of missing true matches, which directly impacts compliance.
- Traditional OFAC screening methods often generate a high number of false positives, making it a huge burden and difficult to screen each transaction of the ACH file, increasing workload and payment processing time, and leading to operational inefficiencies.
Batch File Processing and “File Trust”
- ACH payments files often arrive in bulk files from originators (corporates or third-party senders).
- ODFIs may not “unbatch” files for detailed screening due to processing burdens, instead trusting that the originator has already done proper OFAC screening.
- This delegation creates a compliance blind spot and introduces third-party risk.
Dual Responsibility Between ODFIs and RDFIs
- Unlike wires (where the sending bank carries most compliance responsibility), ACH compliance duties are split:
- ODFIs must screen originators,
- RDFIs must screen receivers.
- This split leads to gaps or overreliance on counterparties, especially if roles aren’t clearly defined or processes misaligned.
Same Day ACH and Speed Pressure
- With the expansion of Same Day ACH, banks have less time to screen, investigate, and act on potential OFAC hits.
- Real-time or near-real-time screening becomes essential. However, legacy ACH screening systems are incapable to satisfy the real-time requirement, causing considerable delays. This led FIs to prioritize speed over accuracy, risking compliance breaches.
International ACH Transactions (IAT) Complexity
- IATs carry added sanction risks and require special formatting under NACHA rules.
- IATs must include complete sender and receiver information, but that data is often incomplete or inconsistent.
- Failure to properly flag an international ACH as IAT can lead to regulatory findings or missed screenings.
Technology Limitations
Many FIs use legacy OFAC screening systems that do not support modern and accurate name matching algorithms. This results in inefficient screening performance and a high volume of false positives.
- Legacy systems also often lack an intuitive case resolution user interface. This limitation can significantly impact the investigation time of ACH transactions’ alerted lines.
- Difficulty Managing Sanctions List Updates. OFAC and other regulatory bodies frequently update their SDN and other sanction lists. If a FI performs list updates manually, it may (and often does) cause missed or delayed list synchronization and, hence, leads to compliance breaches.
In summary, high volumes, data limitations, changing regulatory requirements, technological limitations, and skilled resources constraints form a web of challenges around ACH sanctions screening. These challenges are interrelated. For instance, high volume combined with poor screening technology magnifies false positives, which then strain resources.
Regulators, including OFAC and FinCEN, expect automated, auditable, and comprehensive screening of ACH payments. They can take enforcement action (including hefty fines) if they find that a FI is neglecting AML and sanctions screening for the ACH payments they process.
Acknowledging these pain points is the first step. The next step is to apply smarter processes and technology.
A technological solution built to handle ACH payments sanctions screening is required to meet these challenges. Such solutions must address the unique structural, operational, and regulatory challenges of ACH payments processing. Below is a breakdown of the key features required to effectively overcome those pain points.
Smarter processes and advanced technology for ACH payments screening
| Feature | Why it’s needed | Required capability | Benefit | Fincom AML Screening |
