Know Your Customer (KYC) has long been treated as a box-ticking exercise at account opening, but for financial institutions the real danger lies in what happens afterwards.
According to Alessa, KYC is the process banks use to verify a customer’s identity, understand the nature of the relationship, and gauge the risk of money laundering, terrorist financing and fraud – and it does not stop once an account is live.
Alessa recently discussed what is KYC in banking, detailing its definition, requirements & examples.
While requirements differ across jurisdictions, the goal is universal: institutions must know who they are dealing with and be able to spot unusual or suspicious behaviour. Globally, standards are shapeWhy KYC failures leave banks exposed to financial crime. Read now for the strategic intelligence FinTech leaders trust.d by the Financial Action Task Force (FATF), whose recommendations underpin anti-money laundering (AML) rules in more than 200 jurisdictions.
In Canada, obligations sit under the Proceeds of Crime (Money Laundering) and Terrorist Financing Act (PCMLTFA), overseen by FINTRAC, while in the US they flow primarily from the USA PATRIOT Act, the Bank Secrecy Act and FinCEN regulations.
At its heart, KYC answers three questions: who is this customer, what financial crime risk do they pose, and does their activity remain consistent with what the institution knows about them? These answers inform onboarding decisions, transaction monitoring, investigations and regulatory reporting.
Canadian reporting entities must verify identities through approved methods, understand the purpose of the business relationship, identify beneficial owners, monitor higher-risk relationships and keep records demonstrating compliance. Their US counterparts must run a Customer Identification Program (CIP), perform Customer Due Diligence (CDD), identify beneficial owners, monitor for suspicious transactions and maintain supporting records. Different frameworks, same destination.
The data collected typically spans full legal name, date of birth, address, government-issued identification, occupation, expected account activity, source of funds or wealth, and beneficial ownership details for legal entities. Higher-risk customers face additional demands before an account can be opened.
Crucially, KYC extends far beyond checking ID. A robust programme comprises identity verification, CDD, Enhanced Due Diligence (EDD) for higher-risk customers such as politically exposed persons (PEPs), and ongoing monitoring. Red flags include unexpected international wires, large cash deposits at odds with customer history, ownership changes and dealings with sanctioned or high-risk jurisdictions.
In practice, this plays out daily: banks screening new savings account holders against sanctions and PEP lists, mapping beneficial ownership before onboarding a business, applying EDD to politically exposed persons, flagging a long-standing customer whose transaction pattern suddenly shifts overseas, or reassessing a corporate client’s risk rating after an acquisition changes its ownership.
The stakes are high. Effective KYC helps detect money laundering, prevent fraud and identity theft, satisfy regulators, and reduce reputational risk. Without reliable customer data, sanctions screening and suspicious activity reporting lose much of their power.
Yet KYC remains one of the most resource-intensive corners of AML. Institutions wrestle with manual onboarding, incomplete records, opaque ownership structures, false positive sanctions matches and shifting regulatory expectations across borders. Modern AML and RegTech software is increasingly stepping in, automating identity verification, risk scoring, monitoring and case management while providing a full audit trail.
The bottom line: KYC is not a one-off onboarding hurdle but an ongoing, risk-based discipline – and the institutions that treat it that way are the ones best placed to keep financial crime out.
