Every day, your inbox fills with new applications, and you're tasked with verifying identities, cross-checking documents, and ensuring compliance with ever-evolving regulations. While it may feel like a repetitive task, this process is crucial in safeguarding your institution from financial crime.

Think of the Customer Due Diligence (CDD) process as your institution's security system. Just like you wouldn’t allow an unknown person into your office without verifying their identity, CDD ensures only legitimate customers gain access to your services.

In this article, we’ll guide you through the essentials of the CDD process, helping you gain a deeper understanding to protect your institution against fraud and financial crime.

What is Customer Due Diligence?

Customer due diligence is a critical process used by financial institutions and other regulated entities to verify the identities of customers and business partners, ensuring compliance with anti-money laundering (AML) and counter-terrorist financing (CTF) regulations.

The primary objective of CDD is to confirm that the individual or entity you are engaging with is who they claim to be and that they are not involved in illicit activities or financial crimes. CDD includes several key components that helps you identify, assess and continuously monitor for potential risks posed by these individuals or entities.

Why is Customer Due Diligence Important?

The Customer Due Diligence process is important because it primarily serves as a countermeasure to combat money laundering and a wide range of financial and non-financial crimes.

For banks and financial institutions, CDD is also important in managing compliance risks. This is because without proper CDD measures in place, institutions expose themselves to significant risks, including hefty fines, legal consequences, and reputational damage.

Moreover, with the rapid advancement of technology over the past two decades, criminals now have access to more sophisticated methods to carry out illegal activities. Here, CDD plays an important role as a proactive prevention control to keep criminals out of your ecosystem, at the onset and throughout the business relationship.

Who Must Adhere to CDD Practices?

Customer Due Diligence applies to individuals and entities across various industries. While it is mandatory for organisations in regulated sectors, businesses in unregulated sectors are also strongly encouraged to adopt CDD measures.

Anti-money laundering regulations can change over time, and sectors previously unregulated may come under scrutiny as new risks or data emerge. A proactive approach to CDD helps future-proof your organisation against evolving regulations.

Entities required to follow CDD practices include, but are not limited to:

  • Financial Institutions (FIs)

  • Designated Non-Financial Business and Professionals (DNFBP)

    • Casino and Gaming

    • Real Estate Developers and Agents

    • Precious Metal and Precious Stone Dealers

    • Lawyers, Notaries and Other Independent Legal Professionals

    • Accountants

    • Trusts

    • Corporate Service Providers

  • Non-Profit Organisations (NPOs)

  • Businesses onboarding High-Risk Individuals

When Should You Perform Customer Due Diligence Checks?

Customer Due Diligence (CDD) checks are crucial at various stages of the customer relationship to prevent financial crime and ensure compliance. While CDD is typically performed when establishing a business relationship and throughout the customer lifecycle, it should also be applied to one-off projects or transactions.

Conducting CDD for ad-hoc transactions helps institutions understand the nature of the business and the source of funds. This allows for preemptive safeguards against potential money laundering risks and financial crime exploitation.

CDD should be carried out at the start of business relationship, when major changes to profile or risk occur, when anomalies are detected in transaction monitoring, when high risk customers are identified and when new regulatory requirements surface

Below is an overview of critical points where CDD checks need to be performed:

Onset of Business Relationship

When a customer first engages with a financial institution to open an account or initiate a transaction, CDD must be conducted. This ensures that the customer’s identity is verified and that the institution is not knowingly facilitating illegal activities.

Significant Changes to Customer Profile

If there are substantial changes to a customer’s information or risk profile, such as alterations in the nature of their business, source of funds, ownership, jurisdiction, or transaction behaviour, CDD checks should be conducted again. This ensures that the customer’s details remain current and accurate.

Continuous Transaction Monitoring

Banks and financial institutions must continuously monitor customer transactions to identify any deviation from the customer’s known profile. Suspicious activities must be flagged and investigated to prevent potential involvement in financial crimes.

Identification of High-Risk Customers

High-Risk Individuals (HRIs), such as Politically Exposed Persons (PEPs) and sanctioned parties, pose significant risks for money laundering and corruption. As global regulations evolve, customer due diligence requirements are expanding in scope to include individuals with adverse media profiles, reflecting regulators’ increasing demand for a more comprehensive approach to identifying HRIs.

With tightening regulations, tools like internet-based adverse media searches have shifted from optional to essential for identifying HRIs and ensuring compliance. Once these high-risk individuals or entities are identified, Enhanced Due Diligence (EDD) is required, involving thorough background checks, source of funds verification, and ongoing monitoring to mitigate potential risks.

New Regulatory Requirements

When regulatory requirements change or new laws are enacted, banks and financial institutions must update their CDD procedures to ensure compliance with the latest mandates and maintain regulatory compliance.

Effective Approach to Performing Customer Due Diligence

To effectively conduct customer due diligence, institutions must design their CDD programs to meet, at a minimum, regulatory requirements. While national regulations like FinCEN in the United States play a role, this article focuses on the Financial Action Task Force (FATF) Recommendation 10 due to its broad international scope and relevance in guiding us in this process.

FATF Customer Due Diligence Requirements

FATF Recommendation 10 mandates that financial institutions perform CDD when establishing business relationships, conducting transactions or wire transfers above USD/EUR 15,000, suspecting money laundering or terrorist financing, or when there are doubts about the accuracy of customer information. Appropriate CDD measures to be undertaken include:

  1. Collecting and Verifying Customer Identity Information

Banks and financial institutions must collect identity information from customers and verify it against reliable, independent sources. This also includes business details such as the nature of the business, its address, and the source of funds.

  1. Verifying Beneficial Ownership

Banks and financial institutions must take reasonable steps to identify and verify the beneficial owner. For legal entities, this includes understanding the ownership and control structure of the business.

  1. Understanding the Purpose and Nature of the Business Relationship

Banks and financial institutions must understand the specific services the customer seeks, the types of transactions expected, and the customer’s regular business activities.

  1. Ongoing Monitoring and Risk Assessment

Throughout the course of the business relationship, banks and financial institutions should also monitor and scrutinise transactions undertaken to ensure consistency with the institution’s knowledge of the customer, their intended nature and purpose of the relationship, their risk profile and source of funds.

Example of an Effective Customer Due Diligence Workflow

Next, performing a customer risk assessment, AML & CFT screening, and identifying high-risk individuals. If necessary, conducting enhanced due diligence, followed by ongoing monitoring, periodic reviews, and filing suspicious transaction reports when red flags are detected.

The above customer due diligence workflow is one of the many ways in which banks and financial institutions can effectively perform CDD checks on their customers. At its core, a strong CDD program should help address four critical Know-Your-Customer (KYC) questions:

  1. Who is the customer?

A robust CDD process ensures that banks and financial institutions can accurately verify a customer’s identity and ensure that they are factually who they claim to be. 

  1. Who is the customer not?

Beyond identity verification, an effective CDD process helps institutions identify potential risks by confirming that the customer is not a high-risk individual or bad actors associated with illicit activities.

  1. Is the customer still who they say they are?

CDD does not stop after initial checks. Continuous monitoring is essential in ensuring that the customer risk profile remains consistent over time and that any changes are promptly flagged.

  1. What does the customer do?

Transactions play a key role in facilitating money laundering and financial crime. An effective CDD programme should include real-time monitoring mechanisms to detect unusual transactional activity associated with the customer and alert compliance teams for timely intervention.

By collecting comprehensive customer information and conducting thorough risk assessments, banks and financial institutions can gain a clear understanding of each customer’s risk profile. This information allows for more efficient resource allocation, for instance, low-risk clients can be processed quickly, while more resources and attention can be dedicated to managing higher-risk clients.

What are the Key Trends in Customer Due Diligence?

Customer Due Diligence processes have significantly evolved in recent years, driven mainly by technological advancements, regulatory changes and increasing sophistication of financial crimes. Some of the key trends in CDD processes are as follows:

Increased Use of Technology and Automation

Thanks to the global pandemic which changed the way consumers interact with financial services, banks and financial institutions are also increasingly relying on digital onboarding technologies and automated KYC checks to streamline CDD processes, ensuring quicker, accurate customer verification.

Enhanced Scrutiny on Corporate Structure and Beneficial Ownership

Regulators are pushing for greater transparency around the ownership of legal entities and trusts. Banks and financial institutions are now required to conduct more thorough checks to identify beneficial owners, especially in complex corporate structures. This is crucial for preventing money laundering and terrorist financing.

Ongoing and Real-Time Monitoring

The scope of CDD has evolved in scope from a one-off check in the past to a continuous process today. Banks and financial institutions are increasingly focusing on continuous monitoring of customer risk profiles, relationships, and transactions, ensuring they detect suspicious activities in real-time and adapt to any changes in the customer's behaviour or circumstances.

Strengthened Risk-Based Approach

CDD processes are increasingly adopting a risk-based approach, focusing more resources on high-risk clients, sectors, or jurisdictions. This shift enables institutions to tailor their CDD efforts based on the customer’s risk level, rather than applying a one-size-fits-all approach, aligning with evolving global regulatory expectations.

Harmonisation of Global Regulatory Standards

Over the past few decades, significant progress has been made in aligning international CDD standards. Intergovernmental organisations like the FATF have led efforts to update guidelines regularly, reflecting the growing sophistication in methodologies of financial crime and ensuring that regulations stay ahead of new and emerging threats.

Balancing Customer Due Diligence and Customer Experience

Customer due diligence processes are essential for safeguarding both the financial system and institutions against financial crime. However, these processes often present a challenge. One key challenge is finding the right balance between thorough due diligence and maintaining a smooth customer experience. 

Banks and financial institutions must determine the fine line between conducting sufficient CDD checks and not overwhelming customers with excessive steps. If the onboarding process is excessively cumbersome or filled with hurdles, it can frustrate customers and result in customer exit. 

The goal is to implement comprehensive checks while still ensuring that the customer experience remains as seamless and efficient as possible. To aid us in this process, we turn to technology to help streamline the CDD process from start to end.
