Anti-Money Laundering (AML) and Know Your Customer (KYC) are terms often mentioned together in financial compliance discussions. While they are closely linked, within banking operations AML serves as the broader regulatory umbrella, and KYC acts as the customer-specific frontline defense. This post explores how AML fits within the KYC lifecycle, specifically in banking contexts, to help institutions understand the intertwined roles these frameworks play in preventing financial crime and ensuring regulatory compliance.
What Is AML in KYC in Banking?
AML refers to the comprehensive framework of laws, procedures and technologies designed to prevent illegal funds from entering and circulating through the financial system. It aims to detect and stop money laundering activities before they can cause harm or mask criminal proceeds.
On the other hand, KYC is a structured process banks use to verify customer identities, assess their risk levels, and determine whether they qualify to open accounts or access financial services. It’s the crucial first step in preventing money laundering at the individual customer level.
In essence, AML regulations require KYC procedures to be in place. Think of it this way: KYC is the compliance process, while AML is the compliance objective. KYC is how banks verify and monitor customers, and AML is the overarching goal of stopping illicit funds from moving through the system.
Why AML and KYC Are Critical in Banking
Banks serve as gateways to the global financial system, making them prime targets for illicit actors seeking to launder money or finance unlawful activities. Global regulators such as the Financial Action Task Force (FATF), Financial Crimes Enforcement Network (FinCEN), and the EU’s AML Authority (AMLA) impose strict expectations on banks to maintain robust AML-KYC programs.
Recent financial crime trends highlight evolving challenges:
- Money mule schemes, where criminals recruit others to move illicit funds, are common.
- Synthetic identity fraud is surging.
- Crypto-to-fiat laundering exploiting digital asset platforms has become a major problem.
Failures in AML-KYC compliance have led to severe consequences, including hefty fines and reputational damage. In 2020 alone, banking AML deficiencies resulted in over $10.4 billion in fines worldwide.
Banks that don’t maintain effective AML-KYC controls risk fines, license revocation, and even criminal penalties.
Comprehensive AML KYC Requirements for Banks
1. Customer Identification Program (CIP)
A customer identification program (CIP) is a foundational requirement under AML laws such as the Bank Secrecy Act (BSA) and is further mandated by Section 326 of the USA PATRIOT Act. Regulators, including FinCEN, require banks to implement CIP rules that specify the information collected and verification steps for customers.
Required Information Collection
- For Individual Customers: Full legal name (including aliases and former names), date and place of birth, residential or business address, government-issued ID numbers (SSN, ITIN, etc.), and valid ID documentation like driver’s licenses or passports.
- For Business Customers: Legal business name, trade names, business address, incorporation details, tax IDs (EIN, TIN), business purpose, ownership structures, and beneficial ownership information.
Technologies such as document scanning, biometric facial comparison, and liveness detection assist banks in authenticating documents and verifying customers. Documentary verification includes government-issued IDs and certified documents, while non-documentary methods rely on database and credit bureau checks. Risk-based verification tailors scrutiny levels based on customer risk profiles.
Banks must keep CIP records for at least five years to satisfy regulatory retention requirements.
2. Customer Due Diligence (CDD)
Customer due diligence (CDD) involves assessing the customer’s risk level by considering factors such as the type of account, transaction volume, industry sector, and country of origin. This step ensures banks understand their customers’ expected activity and potential risks.
| Factor | Risk Level Impact |
|---|---|
| Type of Account | Business accounts are often higher risk than personal accounts |
| Transaction Volume | High volumes increase risk |
| Industry/Business Type | Certain industries (e.g., casinos, crypto) are higher risk |
| Country of Origin | Customers from sanctioned or high-risk countries carry more risk |
Banks must also identify beneficial owners for business accounts to prevent hidden risks.
Standard CDD requirements include verifying identity and address, confirming business purpose, anticipating transaction patterns, and verifying sources of funds when necessary.
3. Enhanced Due Diligence (EDD)
For customers who pose higher risks, such as politically exposed persons (PEPs), offshore entities, crypto-related businesses, or accounts with complex transactions, enhanced due diligence (EDD) mandates deeper background checks and more frequent monitoring. EDD ensures banks gain a comprehensive understanding of these customers to mitigate potential AML risks.
4. Ongoing Monitoring
AML and KYC are not one-time tasks but continuous processes. Banks conduct ongoing transaction monitoring to identify suspicious activity, including:
- Structuring or “smurfing” to avoid reporting thresholds
- Unusual transaction patterns or counterparties
- Real-time screening against updated sanctions and PEP lists
- Velocity and threshold checks across multiple channels
Customer profiles are reviewed annually or more frequently for high-risk customers, with event-driven updates based on behavior changes.
Automated risk scoring tools dynamically adjust risk ratings, documenting all review decisions for compliance audits.
Real-World AML-in-KYC Workflow in a Bank
Here’s a typical workflow showcasing how AML integrates with KYC in banking:
| Step | Description |
|---|---|
| Onboarding Initiation | Customer starts account application |
| KYC Identity Verification | Upload ID document and take a selfie to perform biometric verification against government records |
| AML Screening | Automated name checks against OFAC/sanctions lists, PEP lists, and negative news databases |
| Risk Scoring | The AML rules engine assigns a risk tier based on multiple factors |
| EDD Triggered if Needed | Additional verification steps for high-risk customers |
| Account Approved or Rejected | Final decision made based on risk assessment and verification results |
| Ongoing Monitoring | Continuous AML monitoring post-approval |

FAQs
Is KYC part of AML compliance in banking?
Yes. KYC is a critical first step in AML programs to verify customers and assess risk before granting access to financial services. Without proper KYC procedures, banks cannot effectively implement transaction monitoring, conduct meaningful risk assessments, or fulfill their regulatory obligations to prevent money laundering. AML is the overarching compliance framework mandated by regulations, while KYC represents the specific customer onboarding and due diligence processes that enable banks to meet their AML obligations
What are the key differences between AML and KYC in banking?
AML is the broad regulatory framework targeting money laundering prevention, while KYC is the specific customer verification process supporting AML objectives. AML encompasses broader activities including transaction monitoring systems, suspicious activity reporting (SARs), currency transaction reporting (CTRs), sanctions screening, employee training, and compliance program governance. While KYC asks “who is this customer and what risk do they present,” AML asks “what is this customer doing and does it appear suspicious.”
What happens if banks don’t comply with AML/KYC regulations?
Non-compliance with AML/KYC regulations can result in hefty fines exceeding $1-2 billion. In extreme cases, regulators can revoke banking licenses, prohibit specific business activities, or require management changes, while criminal charges may be filed against individual executives for willful violations. Beyond that, financial institutions often face significant reputational damage.
How often must banks review and update customer KYC information?
Review frequency varies by risk.
Low-risk customers (typically individuals with simple banking relationships, stable employment, and no unusual activity patterns) generally require comprehensive KYC reviews every 3-5 years.
Medium-risk customers (small businesses, customers with international connections, or those in moderately regulated industries) typically need reviews every 1-2 years to account for changing business circumstances and risk profiles.
High-risk customers (politically exposed persons, customers in high-risk industries like money services or cannabis, or individuals with complex ownership structures) require annual or even more frequent reviews, with some banks conducting quarterly or continuous monitoring for the highest-risk relationships.
What are common AML checks within KYC?
Typical AML checks include sanctions screening against government watchlists, PEP identification to detect customers with heightened corruption risks due to political positions or family connections, and transaction monitoring. Banks also conduct identity verification through multiple databases to detect synthetic identities, verify Social Security numbers, and cross-reference customer information against credit bureaus and public records. Risk scoring algorithms analyze customer profiles, transaction patterns, geographic factors, and industry associations to assign risk ratings that determine monitoring intensity and service restrictions.
What is enhanced due diligence (EDD) in banking?
Enhanced due diligence (EDD) is an in-depth verification process for high-risk customers that helps ensure banks do not facilitate financial crime unknowingly.
EDD goes far beyond basic identity verification to include comprehensive background investigations, source of wealth and source of funds documentation, detailed business purpose analysis, and enhanced ongoing monitoring with lower transaction thresholds for suspicious activity alerts.
For individual customers, EDD might involve verifying employment through employer contact, analyzing tax returns or financial statements, conducting site visits for business owners, and obtaining detailed explanations for unusual wealth or transaction patterns.
For business customers, EDD includes beneficial ownership analysis to identify ultimate controlling parties, review of business licenses and registrations, analysis of customer relationships and transaction patterns, and sometimes third-party due diligence reports from specialized firms.
