Why It Matters
The United Nations estimates that $800 billion to $2 trillion is laundered globally each year — 2–5% of global GDP. Money laundering enables every form of serious crime: drug trafficking, terrorism, human trafficking, corruption, and tax evasion. Businesses that fail to detect and report suspicious transactions face massive fines, criminal prosecution, and reputational ruin.
The Three Stages
1. Placement
Introducing criminal proceeds into the legitimate financial system:
- Structuring (smurfing) — breaking large sums into small deposits below reporting thresholds
- Cash-intensive businesses — laundering through restaurants, car washes, casinos
- Currency exchange — converting cash into foreign currencies
- Cash smuggling — physically moving cash across borders
2. Layering
Disguising the trail through complex transactions:
- Multiple bank transfers — moving money between accounts across jurisdictions
- Shell companies — creating entities with no real business activity
- Trade-based laundering — over- or under-invoicing international trade
- Real estate — buying and selling property to create legitimate transactions
- Cryptocurrency — using mixers, chain-hopping, and privacy coins
3. Integration
The "cleaned" money re-enters the legitimate economy:
- Luxury purchases — art, jewelry, vehicles, yachts
- Real estate investment — residential and commercial property
- Business investment — legitimate business acquisitions
- Financial instruments — stocks, bonds, insurance products
- Professional services — legal fees, consulting contracts
Red Flags
Businesses should watch for:
- Unusually large cash transactions or frequent transactions just below reporting thresholds
- Complex ownership structures with no clear business purpose
- Transactions with high-risk countries on FATF grey or black lists
- Reluctance to provide identification or inconsistent documentation
- Rapid movement of funds through multiple accounts
- Business activities inconsistent with the customer's profile
- Use of nominees or third parties without explanation
- Overpayment followed by requests for refunds to different accounts
Industries Most Targeted
- Banking and financial services — traditional gatekeepers
- Real estate — high-value, opaque transactions
- Crypto-asset providers — pseudonymous, cross-border, fast
- Luxury goods — art, jewelry, watches, vehicles
- Gambling and casinos — cash-intensive with payout mechanisms
- Professional services — lawyers, accountants creating corporate structures
- Trade and export — invoice manipulation across borders
