Treasury liquidity structures
Pooling, sweeping, and virtual accounts: how group treasury concentrates scattered cash into one working position without losing per-payer detail.
L0 Explain simply
A company with many bank accounts wants its spare cash in one place, working, rather than scattered and idle. Treasury liquidity structures are the arrangements banks offer to do exactly that. Analogy: a household with several jars. Every night you tip the small jars into one big jar so you can see and spend the whole amount — that is cash sweeping, physically moving balances into a central account. Or you leave the coins where they are but add the jars up on paper to get one combined figure — that is notional pooling, where no money actually moves. Group treasurers use these to fund payments from one pot, cut overdraft costs, and see all their cash at once. Which structures are allowed depends on the bank, the countries involved, and the tax and legal rules that apply.
L1 Core concepts
Two families of pooling exist. In physical cash pooling, balances are actually moved — swept — from participating accounts into a single header account, leaving the sub-accounts at zero or at a target balance; the movements are real transfers with real value dates, and intercompany loans arise between the entities involved. The scheduled movement itself is cash sweeping, run daily, on a threshold, or on demand. In notional cash pooling, nothing moves: the bank calculates interest on the combined balance across the accounts as if they were one, so credit balances offset debit balances without any transfer. Physical pooling concentrates the cash but creates intercompany positions to track; notional pooling avoids the transfers but depends on the bank's willingness to offset and on rules that permit it. Many groups combine both across a hierarchy of accounts.
L2 Practitioner view
Reconciliation is where pooling meets its complication: concentrate the cash and you lose the per-payer detail unless you plan for it. Virtual accounts solve this — a single real account is subdivided into many virtual reference accounts, each with its own identifier, often a virtual IBAN, that a payer quotes. Money still lands in one real account, but the virtual identifier tells the receiver which customer or subsidiary paid, so incoming payments reconcile automatically. Operations and treasury teams run sweeps to cut-off deadlines, prove the intercompany loan entries that physical pooling creates, and check that swept balances settled with the correct value dates. A virtual IBAN can also let a group present local-looking account details in several countries while collecting into one place. Naming and capability differ widely between banks, so learn your own bank's model first.
L3 Technical details
The structures carry risks worth naming plainly. Notional pooling relies on the bank offsetting debit and credit balances across entities, which uses the bank's own balance sheet and is constrained by capital rules and by some jurisdictions that limit cross-entity offset; where it is restricted, groups fall back to physical sweeping. Physical pooling turns balances into intercompany loans, which raise tax, transfer-pricing, and legal questions treasury cannot ignore. Virtual accounts and virtual IBANs shift the complexity into identifier management: the mapping from virtual reference to underlying customer must be accurate and current, or the reconciliation gains simply leak back out as exceptions. None of this is settled market-wide; capability, pricing, and permitted structures depend on the bank and the countries a group operates in, so each arrangement is designed case by case with tax and legal advice.

What this simplifies: The jars analogy and the pooling illustrations compress physical sweeping, notional offset, and virtual-account reconciliation into single readable stages; real cash-management products differ by bank and jurisdiction, and permitted structures depend on local tax, capital, and legal rules that this teaching pass does not attempt to state.
