Sweeping

Sweeping, in banking and payments, is the automatic transfer of money between accounts that belong to the same person or organisation, according to rules the account holder sets in advance. A consumer might have surplus funds swept from a current account into savings at the end of each month, or have money moved in to avoid an overdraft. A company might sweep balances from many subsidiary accounts into a central treasury account every evening. The aim is to keep money where it is most useful without the holder having to make each transfer manually.

The term has two main settings. In open banking, especially in the United Kingdom, sweeping refers to transfers between a customer's own accounts at different providers, initiated by a third party using variable recurring payments (VRP). In corporate treasury, it refers to automated cash concentration within a bank or banking group, often through an account sweeping agreement. The word has an unrelated meaning in crypto, where a sweep moves all funds out of a wallet whose key may be compromised.

In the United Kingdom, the Competition and Markets Authority required the nine largest banks, under its open banking remedies, to support VRPs for sweeping. This allows a regulated payment initiation service provider to move money between a customer's accounts, within limits the customer agrees, without the customer having to authenticate each payment. Typical uses include:

• Savings automation. Moving spare cash to a higher-interest savings account at another provider.
• Overdraft avoidance. Topping up a current account from savings when the balance falls low.
• Debt repayment. Paying down a credit card or loan held in the customer's own name.
• Account consolidation. Gathering balances from several accounts into one for budgeting.

Customers set a mandate with parameters such as maximum payment size, frequency and duration, and can revoke it through either the third party or their bank. Because the payer and payee accounts belong to the same person, sweeping qualifies for a strong customer authentication exemption for subsequent payments. Payments beyond sweeping, for example to merchants, fall under commercial variable recurring payments, which the industry has been developing on a separate commercial basis.

Defining exactly what counts as sweeping proved contentious. Regulators and industry bodies set out a definition covering transfers between accounts in the same name, including certain credit accounts, and excluding payments to merchants or third parties. The scope matters because banks are obliged to offer sweeping access but can charge for, or decline, wider uses.

Businesses use sweeping as part of cash management. In a typical physical sweep, the balances of subsidiary or operating accounts are transferred to a header account at the end of each day, leaving the subsidiary accounts at zero, as in a zero balance account structure, or at a set target balance. The reverse transfer funds accounts that are overdrawn. This is a form of cash concentration and is often combined with a cash pool, in which group companies share liquidity.

Investment sweeps move surplus balances overnight into interest-bearing products such as money market funds and return them the next morning, a service described under automated investment sweep. Banks also sweep client deposits between affiliated banks to extend deposit insurance coverage, through a deposit sweep program.

For consumers, sweeping can reduce overdraft fees, raise interest earned on savings and make debt repayment easier, without relying on manual transfers. For businesses, it gives treasury a single view of cash, reduces external borrowing by using internal surpluses and cuts idle balances in many accounts. For the payments system, open banking sweeping increases competition among savings and credit providers, because customers can keep their main account while easily using better products elsewhere.

Sweeping relies on accurate rules and reliable connections. Badly set parameters can drain an account before a large payment is due, and outages at a third party can stop expected transfers. For open banking sweeping, consumer protection depends on the authorisation of the third-party provider, clear consent and easy revocation. Corporate sweeping across legal entities raises tax, legal and intercompany lending issues, such as transfer pricing on interest and restrictions in some countries on cross-border pooling, so groups document their arrangements carefully.
