A concentration account centralises funds, but the term has two uses

A concentration account is a central account used to bring funds together. In corporate treasury, it is commonly a company’s header account, receiving funds from operating or collection accounts. Within a bank, it is an internal account used to process and settle customer transactions, usually on the same day.

For companies, the purpose is cash visibility and efficient movement of liquidity. For banks, the priority is preserving the record that connects each transaction with the relevant customer, according to the Federal Financial Institutions Examination Council’s Bank Secrecy Act and anti-money-laundering manual.

Two uses of the term

• Corporate treasury concentration account: A company transfers funds from dispersed depository or operating accounts to a central account, often at its primary bank. This cash-concentration process pools funds for future use, and the central account may be called a header account.
• Bank-internal concentration account: A bank uses an internal account to facilitate processing and settlement of multiple or individual customer transactions. The FFIEC manual says such accounts may also be called special-use, omnibus, suspense, settlement, intraday, sweep or collection accounts.

Both uses centralise flows, but they are not interchangeable. Corporate cash concentration is a liquidity-management arrangement. The bank-internal definition concerns transaction processing and the controls required to maintain traceability.

How corporate cash concentration works

A company can arrange for balances in collection or operating accounts to be transferred, or swept, to its concentration account under an agreed process.

Illustrative flow:

• Regional account A: $40,000
• Regional account B: $25,000
• Online collections account: $35,000
• Central concentration account after the sweep: $100,000

The company’s treasury team can then view a consolidated cash position rather than separate balances. The Association for Financial Professionals describes the principal objectives as moving cash efficiently from deposit accounts to the concentration account and gaining visibility over the organisation’s cash position.

Pooling can help an organisation balance excess and deficit cash positions and optimise idle balances. A company may operate more than one concentration account where it has substantial cash flows in several currencies or where regional pools are more operationally efficient.

Ways to pool cash

• Physical pooling: Funds transfer between participating subaccounts and the concentration account. The treasury guidance describes this as a same-currency structure. Where separate entities participate, the movements are accounted for as intercompany loans.
• Notional pooling: A bank makes balancing entries across accounts without physically moving funds. The guidance says banks generally require cross-guarantees from participating entities and credit facilities to support negative balances; cross-border availability may be limited.
• Virtual accounts: These are internal ledgers with their own account numbers. Only the header account is a real legal account, according to the treasury guidance.

A sweep is a transfer mechanism that may be used in a physical-pooling arrangement. The concentration account is the central destination for the cash.

Why bank-internal accounts require controls

The FFIEC manual says bank-internal concentration accounts are frequently used for private banking, trust and custody accounts, funds transfers and international affiliates. The principal risk arises if customer-identifying information, including the customer name, transaction amount and account number, is separated from the transaction. The audit trail can then be lost.

The manual calls for policies, procedures and recordkeeping processes, as well as monitoring to identify and report unusual or suspicious transactions. Its listed controls include prohibiting direct customer access; retaining transaction and customer-identifying information; capturing customer transactions in account statements; frequent reconciliation by someone independent of the transactions; and timely resolution of discrepancies.

A corporate concentration account gathers a company’s cash for central management. A bank’s internal concentration account supports customer-transaction processing and must retain information that keeps each transaction attributable to the customer involved.

Frequently asked questions

How does cash concentration differ from a sweep account?

Cash concentration is the practice of bringing funds from dispersed accounts into a central concentration or header account. A sweep is the transfer process used to move funds between participating accounts and that central account, including in a physical-pooling structure.

What is the difference between physical pooling and notional pooling?

Physical pooling involves actual transfers between subaccounts and a concentration account. Notional pooling uses balancing entries without physically moving funds. The Association for Financial Professionals says banks generally require cross-guarantees and credit facilities to support negative balances in notional pools.

Why do banks restrict customer access to internal concentration accounts?

The FFIEC manual lists prohibiting direct customer access as an internal control for concentration accounts. It also warns that separating customer-identifying information from a transaction can cause the audit trail to be lost, undermining transaction monitoring and recordkeeping.

Can a company use more than one concentration account?

Yes. The Association for Financial Professionals says separate currency pools may be more efficient for major operating currencies, and regional pools may be more practical for operations in different regions.
