A large-value transfer system is a payment system built to move high-value, usually time-critical payments between banks and other financial institutions. Typical traffic includes interbank lending and repayment, the cash side of securities and foreign exchange trades, central bank operations and urgent corporate payments. Individual payments can be very large, and the total value settled in a single day in the major systems runs to trillions in the relevant currency.
The phrase is often used interchangeably with wholesale payment system, although "large-value" describes the size of payments while "wholesale" describes the participants and markets served. Most such systems today settle on a real-time gross settlement (RTGS) basis in central bank money, and many are treated as systemically important, which brings them under the international Principles for Financial Market Infrastructures.
Large-value transfer systems in plain terms
A country's payment systems are a bit like its roads. Most traffic is cars: card payments, salary credits and transfers between friends, each small and handled in great numbers by retail systems. A large-value transfer system is the heavy freight route. Far fewer vehicles use it, but each one carries an enormous load, and a breakdown would block the deliveries everything else depends on.
Because the loads are so big, the route is built differently. Each payment is checked and settled on its own rather than bundled with thousands of others, the money moves across accounts at the central bank so there is no doubt that it is good, and the central bank watches closely to make sure the system keeps running even on very bad days.
How they work
Participants, usually banks and some other financial institutions, hold settlement accounts with the operator, which in most cases is the central bank. A participant sends a payment instruction through a secure network, often using Swift or a domestic network carrying ISO 20022 messages. The system checks the instruction and, if the sender has enough balance or available intraday credit, debits the sender and credits the receiver at once. That transfer is final and irrevocable under the system's rules. If funds are short, the payment may wait in a queue, where liquidity-saving mechanisms can offset it against payments flowing the other way.
Not all large-value systems use RTGS. Some are deferred net settlement systems that net payments and settle the balances at the end of the day, while others are hybrid settlement systems that combine the two approaches.
Major examples
- Fedwire Funds Service. Operated by the Federal Reserve Banks, Fedwire is the US dollar RTGS system for high-value interbank and customer transfers.
- CHIPS. The privately owned CHIPS settles US dollar payments, many linked to international trade and finance, using prefunded balances and offsetting.
- CHAPS. The UK's sterling high-value system, CHAPS, settles across accounts in the Bank of England's RTGS service.
- T2. The Eurosystem's T2 replaced TARGET2 in 2023 and settles euro payments in central bank money.
- EURO1. A privately run euro system operated by EBA CLEARING, with participants' positions settled in central bank money at the end of the day.
- Lynx. Canada's high-value system, which in 2021 replaced the Large Value Transfer System (LVTS), a system whose name was simply the generic term.
Large-value compared with retail systems
| Feature | Large-value systems | Retail systems |
|---|---|---|
| Typical payment size | Very large | Small to medium |
| Volume | Relatively low | Very high |
| Settlement method | Mostly gross, in real time | Often net in batches, or instant with deferred settlement |
| Main users | Banks, financial markets, central bank | Consumers, businesses, governments |
| Urgency | Usually time-critical | Varies |
The boundary is not absolute. Companies use large-value systems for property purchases and supplier payments, and instant retail payment systems now handle some sizeable transfers.
Risk and oversight
Because so much value passes through them, large-value systems concentrate risk. A failure could stop the settlement of securities and foreign exchange trades and leave banks unable to meet their obligations. Central banks therefore treat most of them as systemically important payment systems and expect them to meet the Principles for Financial Market Infrastructures, covering legal basis, credit and liquidity risk, settlement finality, operational resilience and governance. Operators run backup sites, contingency procedures and regular testing. Participants manage their own intraday liquidity closely, since a bank that cannot fund its outgoing payments can hold up payments to many others.
