Instant Account-to-Account Payment

An instant account-to-account payment is a payment that moves funds straight from the payer's bank or payment account to the payee's account and makes them available to the payee within seconds, usually around the clock on every day of the year. It runs on an instant payment system rather than on card networks, and no card or intermediary wallet holds the money along the way. Examples include payments through Faster Payments in the UK, SEPA Instant Credit Transfer in Europe, FedNow in the United States, Pix in Brazil and the Unified Payments Interface in India.

Instant account-to-account payments are a fast form of the broader category of account-to-account, or A2A, payments, which also includes slower bank transfers and direct debits. They are usually push payments, initiated by the payer. Many countries now treat instant payments as a public good and have built or mandated systems to provide them, as described under real-time payment systems.

1. The payer starts a payment in a banking app, through a merchant's checkout using pay by bank, by scanning a QR code or using an alias such as a phone number.
2. The payer's bank authenticates the payer, checks the balance and runs fraud and sanctions checks.
3. The payment message, often in ISO 20022 format, is sent to the instant payment system, which forwards it to the payee's bank.
4. The payee's bank confirms the account and credits it, and a confirmation returns to the payer's bank, usually within a few seconds.
5. Settlement between the banks happens in real time in central bank money or through prefunded positions, depending on the system's design.

• Person-to-person transfers. Splitting bills, sending money to family and paying individuals.
• Retail and online payments. Paying merchants by bank, often initiated through open banking payment initiation, as an alternative to cards.
• Bill payments and request to pay. Settling invoices and utility bills, sometimes triggered by a request to pay message.
• Business payments. Paying suppliers, gig workers and refunds instantly, and managing cash in real time.
• Government payments. Disbursing benefits and tax refunds quickly.

Instant payments give payees immediate access to funds, which improves cash flow for businesses and reduces the need for credit. For merchants, they can be cheaper than card payments, with no interchange in many systems, and there is no risk of a chargeback in the card sense. Payment confirmation is final, which simplifies reconciliation. For economies, widespread instant payments can reduce cash use and support financial inclusion, as seen in Brazil and India, where public systems achieved very rapid adoption.

Speed and finality also create risks. Because funds move instantly and cannot easily be recalled, instant payments are a common channel for authorised push payment fraud, where victims are tricked into sending money to criminals, and for moving funds through money mule networks. Countermeasures include Confirmation of Payee and other name checks, real-time fraud monitoring, limits on new payees, delays on high-risk payments and data sharing between banks. In the UK, payment service providers must reimburse most victims of APP fraud on Faster Payments, subject to a maximum and some exceptions. Consumers do not have the card-style dispute rights that apply to card payments, so protections depend on local rules.

Governments and central banks have pushed instant payments through infrastructure investment and regulation. The EU's Instant Payments Regulation requires payment service providers that offer euro credit transfers to offer instant transfers too, at no higher price than standard transfers, and to provide Verification of Payee. Brazil's central bank built and operates Pix and required large institutions to participate. In the United States, the Federal Reserve launched FedNow in 2023, alongside the private RTP network. International work under the G20 cross-border payments programme is exploring links between national instant systems so that cross-border payments can also be instant.

Adoption for retail payments depends on merchant acceptance, a smooth customer experience and incentives that compete with card rewards. Transaction limits in some systems restrict high-value use. Refunds and buyer protection need separate processes. Coverage can be uneven where not all banks participate or offer instant payments to all customers. Despite these issues, instant account-to-account payments are growing quickly and are reshaping domestic payment markets in many countries.
