A settlement institution is the institution on whose books funds are transferred between participants so that their payment obligations are settled. In most payment systems, participants hold accounts with the settlement institution, and settlement happens when it debits one participant's account and credits another's. For the major payment systems of most countries the settlement institution is the central bank, so settlement takes place in central bank money.
The term sits among several similar-sounding roles. A settlement agent manages the settlement process, for example by calculating positions and submitting the resulting entries, while a settlement bank is usually a participant bank that settles on its own behalf and often for others. One body sometimes plays more than one of these roles, which is why the terms are often blurred in everyday use.
Settlement institutions in plain terms
Think of a group of friends who all keep money in the same savings club. When one friend pays another, nobody hands over notes; the club's treasurer simply moves the amount from one member's page in the ledger to another's. The treasurer's book is where payments actually become real. That treasurer is the settlement institution.
Because the treasurer's book is the final word, the safety of everyone's money depends on how trustworthy the treasurer is. That is why most countries make the central bank the treasurer for the most important payments between banks: a central bank cannot run out of its own currency, so a balance in its books is as safe as money gets.
Role in a payment system
The settlement institution provides the accounts across which value finally moves. In a real-time gross settlement (RTGS) system, it debits and credits participants' accounts one payment at a time. In a deferred net settlement system, a separate clearing house may calculate net positions, and the settlement institution then posts those positions to participants' accounts. In both cases, settlement is complete only when the settlement institution has made the entries.
Many settlement institutions also provide credit to make settlement smoother. Central banks commonly offer intraday credit against collateral so that participants can make payments before incoming funds arrive. The settlement institution's rules define when entries are final and irrevocable, and those rules are often backed by law.
Central bank and private settlement institutions
International standards prefer settlement in central bank money where practical, because it carries no credit or liquidity risk for participants. Fedwire, CHAPS, T2 and most other large-value systems settle on the books of the central bank, which is both operator and settlement institution.
Some systems settle in commercial bank money on the books of a private institution. Participants then face the risk that the settlement institution itself fails, so the Principles for Financial Market Infrastructures expect such institutions to have strong capital, limited activities and robust risk management. CLS Bank International is a special case: it settles foreign exchange trades on its own books, but its accounts are funded through the RTGS systems of the central banks whose currencies it handles. In some smaller or regional arrangements a commercial bank acts as settlement institution for others, an arrangement close to correspondent banking.
Settlement institution, settlement agent and settlement bank
| Role | What it does | Typical example |
|---|---|---|
| Settlement institution | Holds the accounts on whose books settlement entries are made | A central bank for its national RTGS system |
| Settlement agent | Manages the settlement process, such as calculating net positions and instructing entries | A clearing house operator that sends net positions to the central bank |
| Settlement bank | A participant that settles directly, often also for indirect participants or a CCP's members | A large commercial bank holding a settlement account at the central bank |
These roles can overlap. A central bank that operates its own RTGS system is both settlement institution and settlement agent. A clearing house that calculates positions and instructs the central bank is a settlement agent but not the settlement institution. A commercial bank that holds a settlement account at the central bank is a settlement bank, and for its own customers it acts as a settlement institution in a looser sense, because their payments to each other settle on its books.
Why the distinction matters
Identifying the settlement institution tells participants where settlement risk ultimately lies. If it is a central bank, the remaining risks are mainly operational and legal. If it is a private institution, participants also bear credit risk on it. Regulators look at this when assessing payment systems, and participants consider it when deciding how much liquidity to hold in the system and what settlement finality protections apply.
