Real-Time Gross Settlement (RTGS)
Real-time gross settlement is the settlement of payments one by one, in central bank money, the moment each is processed and with finality — as opposed to net settlement, where obligations are accumulated and settled as a balance at fixed times. Fedwire, CHAPS and the euro area's T2 are RTGS systems; they move the largest values in each economy and are the accounts everything else settles into.
- Also known as
- RTGS, Gross settlement, Wholesale payment system
- Used at
- high-value and time-critical payments — interbank transfers, securities and FX settlement, house purchases, the final leg of card and retail schemes
- Binding
- yes — settlement in an RTGS system is final and irrevocable by law once the central bank has made the entry
- Typical operators
- the central bank — the Federal Reserve (Fedwire), the Bank of England (CHAPS), the Eurosystem (T2, which replaced TARGET2 in 2023)
- Typical access
- banks hold settlement accounts directly; since 2018 UK non-bank payment institutions can too, which is how Wise, then TransferWise, became the first fintech with direct access
- Parties
- the central bank, its direct participants, and the indirect participants — most fintechs — who settle through a direct one
How RTGS works in practice
In a net system, a bank's payments to and from every other bank over the day are added up and only the balance moves, at a set time, from the accounts the banks hold at the central bank. It is efficient and it carries risk: until settlement, every bank is exposed to every other bank's ability to pay its net position at the end of the day. RTGS removes that by settling each payment individually as it arrives, debiting the sender's central bank account and crediting the receiver's, with no netting and no waiting. The cost is liquidity: a bank must have the money in its account at the moment each payment goes, so RTGS participants manage intraday liquidity actively and central banks lend it against collateral.
The value that flows through these systems dwarfs everything else — Fedwire settles trillions of dollars on an ordinary day — and finality is the point. A CHAPS payment, once made, cannot be recalled; a house completes on it. Retail payment schemes, card networks and the faster-payment systems all settle their own participants' net positions across RTGS accounts, which is why direct access matters: a fintech that settles through a bank depends on that bank's willingness to keep it, and a fintech with its own settlement account depends on the central bank.
For a fintech acquisition, direct access is an asset that does not appear on the balance sheet, and one that the regulator's change-of-control review can put at risk.
Example
A payments company settles its customers' outgoing transfers through a sponsor bank, which holds the company's funds in a client account and submits CHAPS payments on its behalf. The sponsor's cut-off is 15:30; a customer's £2.4m property completion instructed at 15:45 waits until the next morning, and the buyer's solicitor charges a day's delay. The company applies for direct CHAPS access: a settlement account at the Bank of England, £5m of intraday liquidity to fund, and a fourteen-month process. Once live, its cut-off moves to 17:40, its sponsor fees of about £900,000 a year fall away, and its dependence on a bank that could give notice ends. A prospective acquirer, itself a bank, notes that the company's access was granted to a non-bank and will be reassessed if a bank owns it.
Common mistakes
- Confusing RTGS with instant retail payments; a faster-payment scheme settles between its members net, across an RTGS account. - Assuming a payment sent to an RTGS system can be recalled if the details were wrong. - Underestimating the intraday liquidity a direct participant must fund. - Building on a single sponsor bank with no fallback, so the sponsor's notice period is the company's survival horizon. - In diligence, missing that direct access is granted to the applicant and reviewed on a change of ownership.
