Underground banking refers to unlicensed parallel banking networks, such as hawala, that take deposits, extend credit, and settle value outside regulated channels. They run on trust and net settlement with no supervisor watching, which is where the real risk lies, not in the informal model itself.
What is underground banking, in plain English?
Underground banking is a banking system that operates outside the regulated one. Networks like hawala and hundi take in money in one place and pay it out in another, extend credit, and settle balances between operators, all without licenses, supervision, or the record-keeping a bank must maintain. To the customer it feels like a fast, cheap money transfer; underneath, it is a parallel financial system running on relationships rather than rails.
The mechanism is trust and net settlement. When someone hands cash to an operator to send abroad, the operator contacts a counterpart in the destination who pays out the equivalent, and the two settle up later, often by netting many transfers against each other rather than moving money for each one. No funds necessarily cross the border for any individual transfer, which is precisely what makes the flow hard to see from any regulated vantage point.
These systems are also called informal value transfer systems or IVTS, and they serve enormous volumes of legitimate activity, especially remittances to regions poorly served by banks. Lumping all of them in with crime misses the point. The defining risk is the lack of licensing and controls, no customer checks, no monitoring, no supervisor, which is what makes them attractive to launderers, not the informal model in itself.
How a value transfer settles
- Pay in — Local deposit. A customer hands cash to an operator in one country to send value abroad.
- Instruct — Message the counterpart. The operator contacts a partner in the destination and passes a code or reference for the payout.
- Pay out — Local disbursement. The partner pays the recipient the agreed amount, with no cross-border transfer for that transaction.
- Settle — Net the books. Operators reconcile balances over time by netting, offsetting trade, or occasional bulk transfers.
Who is involved?
Who | Their role |
The operators | Run the network, take deposits and pay out, and settle balances among themselves. |
The customers | Send and receive value, mostly for legitimate remittances, sometimes to move illicit funds. |
The settlement layer | Where operators net balances, often through trade, cash movements, or reciprocal payouts. |
Banks and regulators | See only the local funding and payout legs, with the cross-border link hidden in operator ledgers. |
What it looks like in practice
In practice
A bank notices a small trading business whose account regularly receives cash deposits from many unrelated individuals and periodically sends larger payments to counterparts overseas and to accounts in higher-risk regions. The business does not obviously sell enough to explain the flows.
What the bank cannot see is that the account is one operator's leg of an informal network: the local deposits are customers paying in, the outbound payments are periodic settlement, and the matching payouts happen abroad through a partner. Each visible leg looks like ordinary business, while the cross-border link that ties them together lives only in the operators' private ledgers.
Why it is hard for operators
The difficulty is that a bank only ever sees one leg at a time. The funding side and the payout side happen in different countries through different operators, and no money necessarily moves across the border for a given transfer, so the connection that would make sense of the activity is invisible. What shows up instead is third-party cash, pooled deposits, and periodic payments to high-risk routes, which are suggestive but not conclusive.
The framing matters too. Because these networks carry vast legitimate remittance volumes, treating every hawala-style flow as criminal is both wrong and unworkable. The productive stance is to focus on the absence of licensing and controls: whether the operator is registered where required, whether there is any customer diligence or monitoring, and whether the visible legs are consistent with a lawful money transfer business rather than a channel for illicit value.
What to watch in the data
- Pooled third-party cash. Many unrelated individuals depositing cash into one account that then sends value abroad.
- Local legs only. Funding and payout activity that is domestic, with the cross-border link never visible.
- High-risk routes. Periodic payments to counterparts or accounts in regions associated with informal networks.
- Business mismatch. Flows that exceed what the stated business could plausibly generate.
- No licensing. An operator acting as a money transmitter without the registration or controls the activity requires.
Quick questions
Is underground banking illegal?
It depends on licensing. The informal model itself is not inherently criminal and carries huge legitimate remittance volume, but operating as an unlicensed money transmitter where a license is required is unlawful, and the lack of controls is what enables abuse.
How does hawala relate to underground banking?
Hawala is a specific and well-known form of underground banking. Underground banking is the broader category of unlicensed parallel networks, which also includes hundi and other informal value transfer systems.
Why does no money cross the border?
Operators settle by netting many transfers against each other rather than moving funds for each one. A deposit in one country is offset by a payout in another, and balances are reconciled later, so individual transfers need no cross-border transfer.
What makes it attractive to launderers?
The absence of customer checks, monitoring, and records, plus settlement that hides the cross-border link. Illicit value can enter and exit without the diligence a regulated transfer would apply.
What can a bank actually see?
Usually only the local funding or payout leg: pooled third-party cash and periodic payments, sometimes to high-risk regions. The connecting cross-border link stays inside the operators' private ledgers.
How should a team handle suspected underground banking?
Assess whether the operator is licensed and applies any controls, examine the visible legs for consistency with a lawful business, and file suspicious activity reporting where the standard is met, without assuming all informal transfer is criminal.
