An operational bank account, often called an operating account, is the bank account a business uses to run its day-to-day activities: receiving revenue, paying suppliers and staff, settling taxes and covering routine costs. It holds the firm's own money, as opposed to money held for customers, funds set aside as reserves or deposits locked for a particular purpose. Most organisations, from a small shop to a multinational, have at least one.
The term matters most where a business must keep different kinds of money apart. Payment firms, brokers, lawyers and escrow agents hold customer funds in safeguarding or client money accounts, and their own operating funds in a separate operational account. In bank regulation, a related term, "operational deposits", describes balances that corporate clients keep at a bank because they need them for clearing, custody or cash management services.
Operational bank account in plain terms
Think of a family with a household account for groceries and bills, a savings account for emergencies and a separate pot of money they are looking after for a relative. The household account is the one that moves every day; the others are kept apart so nobody spends them by mistake. A business's operational account is its household account.
For firms that look after other people's money, keeping the pots apart is not just tidy, it is the law. If the firm fails, the separation shows clearly which money belongs to customers.
How businesses structure operating accounts
Larger organisations rarely use one account for everything. A common structure, set up as part of treasury management, includes:
- Main operating account. The central account through which most of the firm's own cash flows, often a business bank account at the firm's main bank.
- Collection accounts. Accounts that receive customer payments and card settlements, feeding accounts receivable; see collection account.
- Disbursement accounts. Accounts for paying suppliers and accounts payable, sometimes with positive-pay controls; see disbursement account.
- Payroll and tax accounts. Dedicated accounts for payroll and tax remittances, which make reconciliation and audit easier.
- Reserve accounts. Funds held back for a lender, card acquirer or regulatory requirement, kept in a reserve account.
Balances are often moved automatically using sweep accounts or zero-balance accounts, and multinational groups may link operating accounts in a cash pool. Treasury teams monitor them daily for cash positioning and cash forecasting, and accountants match them to the books through bank reconciliation.
Operational accounts at payment and money service firms
For electronic money institutions, payment institutions, money transmitters and brokers, the line between operational and customer accounts is a core regulatory duty. Customer funds go into designated safeguarding, client money or for-benefit-of accounts under segregation of funds rules; the firm's revenue, fees and capital sit in its operational account. Fees earned from customers must be moved out of the safeguarding account promptly, and the firm's own money must not be used to top up or blur the customer pool beyond what the rules allow. Mixing the two, known as commingling, is a frequent finding in supervisory reviews and a major cause of losses when such firms fail. Banks that open an MSB bank account usually ask which accounts are operational and which hold customer money.
Operational deposits in bank liquidity rules
From a bank's point of view, some corporate and institutional balances are "operational" because the client cannot easily move them. Under the Basel Committee's Basel III Liquidity Coverage Ratio (published 2013), deposits that a client keeps to support clearing, custody or cash management services, where the client has a substantive dependency on the bank, can be assumed to run off at 25% in a 30-day stress scenario, rather than the much higher rates applied to other wholesale funding. Any part fully covered by deposit insurance can receive the lower rate given to stable retail deposits. Balances above what the client needs for those services do not qualify, and correspondent banking and prime brokerage balances are generally excluded. Banks must therefore identify which client balances are truly operational, a key input to managing liquidity risk.
Good practice and risks
Keeping operational accounts at more than one bank reduces the risk that a single bank failure or outage stops payroll, a lesson many US firms drew from the 2023 regional bank failures. Clear naming, approval limits, dual authorisation and daily reconciliation reduce fraud and error, and a corporate treasury usually sets minimum and maximum balances so cash beyond working capital needs is invested or moved to safer accounts.
