Definition

RTGS Real-Time Gross Settlement refers to a clearing process in which payments are settled individually and immediately. The name reflects both characteristics:

  • Real-Time – Processing takes place continuously throughout the business day, not in batches at fixed times.
  • Gross Settlement – Each payment is processed individually on a gross basis; there is no offsetting against payments in the opposite direction.

RTGS is also a component of the TARGET system. Large-value payments between participants are processed here on a final and irrevocable basis.

Gross vs. net

RTGS is best understood by looking at its counterpart: the net settlement system. Both perform the same function but with different priorities. Net settlement systems—such as the Deutsche Bundesbank’s SEPA Clearer(opens in new tab)—are designed to handle high transaction volumes. Transactions are netted against one another within a processing cycle to conserve participants’ liquidity.

With RTGS, speed is the priority.

RTGS versus cyclic net settlement — four banksFour banks exchange six payments: A to B 100, B to C 80, C to A 50, B to A 60, D to A 40 and A to D 70. In the RTGS system every payment is settled on its own and is final the moment it settles, so the full gross amount of 400 has to be funded. In the cyclic net settlement system the payments only change the running net positions; nothing is settled until the cycle closes. At the end bank A owes 20 and bank B owes 40, while bank C and bank D receive 30 each, so only 60 actually moves. Same payments, a fraction of the liquidity — but the net system carries an open exposure until the cycle closes.A → B 100B → C 80C → A 50B → A 60D → A 40A → D 70RTGSreal-time gross settlementNet settlementcyclic, e.g. SEPA ClearerBank ABank BBank CBank DRTGSsettles one by one100100A → B 100 ✓8080B → C 80 ✓5050C → A 50 ✓6060B → A 60 ✓4040D → A 40 ✓7070A → D 70 ✓liquidity actually moved100180230290330400Bank ABank BBank CBank Dclearing cyclecollects — settles at the end1008050604070Bank A0−100−50+10+50−20Bank B0+100+20−40Bank C0+80+30Bank D0−40+30no money has moved yetcycle closed — net positions final20403030liquidity actually moved060Four banks, six payments — the same six on both sidesRTGS: every payment settles on its own, immediately and finallyThe net system only moves the positions — no money leaves a bankAt the cycle end two banks owe (A 20, B 40) and two receive (C 30, D 30)Only those net positions are settled: 60 in, 60 out400 against 60 — same payments, a fraction of the liquidity, but an open exposure until the cycle closes
Gross versus net settlement — four banks, six payments, a very different liquidity need

Because the high liquidity requirement is the weakness of the procedure, modern RTGS systems have mechanisms that mitigate it without sacrificing finality:

  • Queues – await payments that cannot be covered immediately, instead of being rejected
  • Priorities – urgent payments are prioritized
  • Scheduled payments – orders are set for a specific time
  • Reservations– liquidity is held for specific purposes
  • Optimization – the system searches the queue for offsetting payments and processes them together

RTGS in the Eurosystem

In the euro area, RTGS is not a standalone application but a component of T2. The latter went live in March 2023, replacing TARGET2, and consists of two parts:

  • CLM (Central Liquidity Management) for liquidity management, with the MCA (Main Cash Account) as the central account
  • RTGS for the processing of payments, using the RTGS DCA (Dedicated Cash Account)

In addition, depending on their participation, institutions maintain further accounts—usually a T2S DCA for securities settlement and a TIPS DCA for real-time payments(opens in new tab).

RTGS outside the Eurosystem

Almost every major currency has its own RTGS system operated by the respective central bank—such as Fedwire in the USA, CHAPS in the United Kingdom, and SIC in Switzerland.

The common denominator is settlement in central bank money. This fundamentally distinguishes RTGS systems from private-sector clearing houses and is the reason why they are classified as systemically important infrastructure and subject to corresponding oversight.
