Definition (canonical)
Anti-Money Laundering (AML) is the framework of laws and duties designed to stop criminal money from entering the legal economy — by forcing businesses that handle money and transactions to know their clients, monitor activity and report suspicions. It converts private firms into the financial system's first line of detection.
Who is obligated
The core list is broadly universal: banks and payment institutions, investment and insurance firms, currency exchanges and crypto-asset providers, notaries, lawyers and accountants for transactional work, real-estate agents, high-value goods dealers above cash thresholds. Each jurisdiction tunes the perimeter, but the trend is one-directional: broader coverage, lower thresholds, more sectors — crypto being the last decade's headline addition. If your business touches other people's money or high-value transfers, assume the perimeter is moving toward you.
The duty stack
Obligated entities must run a written, risk-based program: CDD (customer due diligence) — identify and verify clients and their beneficial owners before the relationship (KYB for entities); risk assessment of clients, products and geographies with enhanced diligence for high risk (PEPs, sanctioned-adjacent, opaque structures); ongoing monitoring of transactions against the expected profile; reporting suspicious activity to the national FIU without tipping off the client; record-keeping for statutory periods; training and an appointed compliance officer. Regulators grade the PROGRAM, not just outcomes — missing paperwork is a violation even when no laundering occurred.
Red flags and the cost of failure
Recurring laundering patterns every business should recognize: transactions with no economic rationale, structuring (many payments just under thresholds), sudden third-party payers unrelated to the contract, prices detached from market, shell counterparties with no real activity or web presence, pressure for cash or crypto in unusual contexts. Penalties for program failures reach millions and — increasingly — personal liability for management; the reputational sentence of an AML scandal usually outlasts the fine.
FAQ
My firm is not obligated — does AML concern me? Indirectly, always: your bank screens YOUR transactions, and opaque counterparties can freeze your payments. Basic counterparty hygiene is self-defense.
AML vs sanctions screening? Separate regimes that overlap operationally — sanctions bind EVERYONE, obligated or not; screening usually rides the same tooling.
What triggers a suspicious activity report? Suspicion, not proof — the reporting threshold is deliberately low, and the obligation is to report, not to investigate.
