Article summary

TL;DR

Real-time gross settlement (RTGS) is a way for banks to settle payments one at a time, as soon as each is accepted, for the full amount and without netting. Central banks run most RTGS systems, such as Fedwire in the US, T2 in the euro area, CHAPS in the UK and RTGS in India. Settled payments are final.

RTGS stands for real-time gross settlement: each payment settles on its own (gross), as soon as it is accepted (real time).
A settled RTGS payment is final and irrevocable. Fedwire calls its transfers immediate, final and irrevocable once processed.
The trade-off is liquidity: banks must fund the full amount of every payment, while net settlement only needs the net balance.
In India, RTGS has a ₹2 lakh minimum, no maximum, and has run 24x7 since December 14, 2020.

What is real-time gross settlement?

The Committee on Payments and Market Infrastructures at the BIS, which sets the vocabulary central banks use, defines RTGS this way:

The real-time settlement of payments, transfer instructions or other obligations individually on a transaction-by-transaction basis.

CPMI Glossary, real-time gross settlement (RTGS)

"Real time" means no waiting for a batch. "Gross" means each payment settles for its full value, not netted against others. When a bank sends a payment, the system checks it and checks that the sender has enough funds or credit. If it does, the payment settles and is typically unconditional and irrevocable. If not, the payment is queued or rejected.2

Most countries run one, usually at the central bank:

System	Where	What the operator says
Fedwire Funds	United States	Transfers are "immediate, final, and irrevocable once processed." Open 9:00 p.m. ET the day before to 7:00 p.m. ET.3
T2	Euro area	The Eurosystem's RTGS, launched in March 2023 to replace TARGET2. Settles in central bank money, Monday to Friday.4
CHAPS	United Kingdom	Run by the Bank of England on its RTGS. About 0.5% of UK payment volumes but 92% of sterling payment values.5
RTGS	India	Run by the RBI. Minimum ₹2,00,000, no maximum, 24x7x365 since December 14, 2020.6

RTGS vs deferred net settlement

The CPMI defines deferred net settlement (DNS) as settlement "on a net basis at the end of a predefined settlement cycle."1 ACH-type batch systems work this way.

	RTGS	Deferred net settlement
Settlement timing	Each payment, continuously during the day	Net balances, at the end of a cycle
Liquidity need	High: the full amount of every payment	Much lower: only net positions
Settlement risk	Final payment by payment, so little exposure between banks	Credit and liquidity risk until settlement; payments can be unwound if a bank fails

Source: CPSS-IOSCO, Annex D.2

The line is blurring. Many RTGS systems now queue payments and offset them against each other to save liquidity. The CPMI calls these "hybrid" systems.1 CHIPS is a private example of that design.

RTGS is also not only for large payments. The Federal Reserve described FedNow as "a new interbank 24x7x365 real-time gross settlement (RTGS) service with integrated clearing functionality."7 It went live on July 20, 2023, for instant payments.8 For that category, see real-time payments.

Benefits and risks of RTGS

Benefits

Each payment is final once settled, not at the end of the day
Less credit and liquidity exposure between banks during the day
Settlement in central bank money, not a claim on a commercial bank

Risks

Liquidity risk: banks must fund the full amount of every payment
Queues and delays when a bank waits for incoming funds
Operational risk: one central system, so an outage stops payments

International standards say an RTGS system "can therefore require relatively large amounts of intraday liquidity." Banks draw it from central bank balances, incoming payments and intraday credit, and queues or other liquidity-saving tools reduce the need.2

For operational risk, Principle 17 asks a payment system to resume critical IT systems "within two hours following disruptive events" and to finish settlement by the end of that day.2

For a business, the practical point is finality. An RTGS payment cannot be pulled back like a card payment. In India, the RBI FAQ says the beneficiary bank must credit the account within 30 minutes, or return the funds within one hour if it cannot.6 Check the account details before you send.

Frequently asked questions

What are the risks associated with RTGS operations?

The two main ones are liquidity risk and operational risk. A bank must hold enough funds or intraday credit to cover the full amount of each payment, or its payments wait in a queue. And if the central system goes down, payments stop. International standards ask payment systems to resume critical IT systems within two hours of a disruption and to finish settlement by the end of that day.

What is the minimum amount for RTGS in India, and what are the timings?

The Reserve Bank of India sets the minimum at ₹2,00,000, with no upper limit. RTGS has been available 24x7x365 since December 14, 2020. The beneficiary bank must credit the account within 30 minutes of receiving the transfer message. Your own bank may set its own limits for online transfers.

Is RTGS the same as an instant payment system?

Not quite. Classic RTGS systems like Fedwire or CHAPS serve large, mostly interbank payments during set hours. Instant payment systems serve everyday payments around the clock. Some are built on the RTGS model: the Federal Reserve described FedNow, live since July 20, 2023, as an interbank 24x7x365 RTGS service with clearing built in.
