Laundering Typologies & Money/Commodities Flows

5 min read · CFCS

Recognize the patterns the exam loves: trade-based laundering, shell companies, smurfing, hawala, and commodity flows. Learn to name the typology from a messy scenario.

Typologies are the exam's bread and butter

  • Typology = a recurring method criminals use
  • Recognizing the pattern beats memorizing definitions
  • Today: TBML, shells, smurfing, value transfer
  • Match red flags to the typology

A typology is just a recurring method criminals use to launder or move money. The CFCS exam leans heavily on typologies because the real skill isn't reciting a definition, it's recognizing a pattern in a messy scenario. So in this lecture we'll walk the big ones: trade-based laundering, shell and front companies, smurfing and structuring, and informal value-transfer systems.

As we go, train yourself to do the thing the exam rewards: read a fact pattern, then name the typology it fits and the red flag that gives it away. FATF publishes typology reports for exactly this reason, cataloguing how methods evolve, and the exam mirrors that approach. A useful habit: for each typology, fix in your mind one signature red flag and one counter-measure, so that when a scenario appears you can move from recognition straight to the control that addresses it.

Trade-based money laundering

  • Mis-invoicing: over- or under-stating price or quantity
  • Moves value across borders disguised as trade
  • Phantom shipments and multiple invoicing
  • FATF and FinCEN both flag TBML as high-risk

Trade-based money laundering, or TBML, hides the movement of value inside legitimate-looking trade. The core trick is mis-invoicing: over-stating or under-stating the price or quantity of goods so that value shifts between buyer and seller off the books. Other variants include phantom shipments, where no goods actually move, and multiple invoicing for the same shipment.

FATF and FinCEN both treat TBML as a major, hard-to-detect channel. The red flags: invoices that don't match shipping documents, prices far from market value, goods routed through countries with no business logic, and payments from third parties unrelated to the trade. FinCEN's TBML advisory highlights additional tells: a commodity shipped in volumes inconsistent with the trader's known business, or goods that take a needlessly circuitous route.

Remember that under-invoicing moves value to the buyer while over-invoicing moves value to the seller, and the exam expects you to reason out which direction the money is really flowing.

Shell and front companies

  • Shell = no real operations, used to hold/move money
  • Front = a real business masking illicit flows
  • Obscure beneficial ownership behind layers
  • Beneficial-ownership transparency is the counter

Shell companies and front companies are the launderer's favorite tools. A shell company has no real operations; it exists on paper to hold accounts and move money. A front company is a genuine, operating business that masks illicit flows within real ones, the classic cash-intensive restaurant.

Both work by hiding the beneficial owner, the real human being who ultimately controls the money, behind layers of entities and nominees. The counter-measure, and a major regulatory trend worldwide, is beneficial-ownership transparency: forcing companies to disclose who really owns and controls them so investigators can pierce the layers. Watch for a company with no website, no employees, and an address shared by hundreds of other entities, or one whose bank activity bears no relation to its stated business.

FATF Recommendation 24 pushes countries toward beneficial-ownership registries, and being able to identify the natural person behind the structure is a skill the exam rewards directly.

Smurfing, structuring & money mules

  • Smurfing: many people make sub-threshold deposits
  • Structuring: splitting transactions to dodge reporting
  • Money mules move funds through their own accounts
  • Watch coordinated, just-under-threshold patterns

Next, the small-amount tactics. Smurfing uses many individuals, the smurfs, to each deposit small sums that together add up to a large laundered amount. Structuring is splitting a single sum into multiple sub-threshold transactions to avoid triggering a report, a crime in its own right.

And money mules are people, sometimes witting, sometimes duped, who let illicit funds pass through their personal accounts. The pattern to watch for is coordination: many accounts moving similar amounts just under reporting thresholds, often in a tight time window. The exam will dress this up in a scenario; your job is to spot the coordinated, just-under-the-line behavior.

Distinguish them cleanly for the exam: structuring is one person splitting transactions to dodge a reporting threshold, while smurfing recruits many people to do the depositing. A common distractor blurs the two. With mules, watch for an account that receives funds from strangers and forwards them within hours, often opened by someone with no obvious reason to be moving such sums.

Informal value transfer & commodity flows

  • Hawala and other IVTS move value without moving cash
  • Settle through trade, offsets, or trusted networks
  • Bulk-cash smuggling and high-value commodities
  • Gold, gems, art store and move value

Finally, value can move without money obviously moving at all. Informal value-transfer systems like hawala settle obligations through trusted networks, trade, and offsets rather than wires, leaving little conventional paper trail. They serve many legitimate users, but they also attract abuse.

Alongside them sit physical flows: bulk-cash smuggling across borders, and high-value commodities like gold, gemstones, and art that store and move value compactly. These connect to our next content area, money and commodities flows. So, recap: TBML, shells and fronts, smurfing and mules, and informal and commodity value transfer.

Learn the pattern, not just the name. One more nuance the exam likes: hawala itself is legal in many places and serves migrant workers sending remittances home, so the typology is the abuse of the channel, not the channel existing. When you see settlement with no corresponding bank wire, or value carried as gold or gems instead of money, name the informal or commodity transfer.

A few CFCS questions on this material — pick an answer to see the explanation.

  1. Q1. A foreign bank must identify and report accounts held by U.S. persons to the IRS or face a withholding penalty on U.S.-source payments. Which regime imposes this, and how does it differ from CRS?

  2. Q2. A criminal moves crypto through a mixer, then chain-hops across several coins and cross-chain bridges before cashing out at a weakly supervised exchange. Investigators can still often trace this because crypto on public blockchains is best described as:

  3. Q3. A laundering scheme spans five countries, and their national financial intelligence units need to share information securely and quickly without waiting on slow formal treaty channels. Which body enables this?

  4. Q4. Under U.S. law, how does 18 U.S.C. 1956 differ from 18 U.S.C. 1957 in terms of what must be proved?
