Deferred settlement is a method in which payment or securities obligations are accepted and processed during a cycle but settled only later, at a predefined time such as the end of the day or a fixed settlement window. Until that time, the receiving institution has a claim on the sender rather than final funds. Retail payment systems, card schemes, cheque clearing and many netting systems use deferred settlement, usually alongside netting to cut the liquidity needed.
Deferred settlement describes timing, not method. It is commonly paired with netting in a deferred net settlement (DNS) system, but the two ideas are separate: obligations can be settled on a deferred gross basis, and netted positions can in principle be settled immediately. Deferred settlement is also not the same as delayed settlement, which refers to settlement happening later than expected, often because of a problem. Its counterpart is immediate settlement, as in real-time gross settlement.
Deferred settlement in plain terms
A restaurant regular might sign for meals all week and settle the bill every Friday. The restaurant serves the food immediately, but the money only arrives at the end of the week. Until Friday, the restaurant is trusting the customer to pay.
Deferred settlement works the same way between banks. Payments are agreed and processed straight away, and customers may even see their money, but the banks only square up with each other at a set later time. Until then, each bank is relying on the others to pay what they owe.
How deferred settlement works
Instructions are accepted throughout a settlement period. The system records each obligation and, if it nets, calculates running positions. At the scheduled settlement window, each participant's settlement obligation, gross or net, is passed to the settlement agent, often the central bank, which debits and credits settlement accounts. Only then do the obligations become final. Many systems run several cycles a day; others settle once, after the close of business.
Because the gap between acceptance and settlement can be hours or days, banks often give customers provisional credit before settlement, which can be reversed if the sending bank fails to settle. This is common in card payments and some automated clearing house payments.
Advantages
- Lower liquidity needs. Settling once, especially on a net basis, requires far less funding than settling each payment as it arrives.
- Efficient bulk processing. Large volumes of low-value payments can be handled cheaply, as in batch settlement.
- Operational simplicity. Participants can plan funding around known settlement times.
Risks
The time gap creates settlement risk. If a participant fails before settlement, others face credit risk on what it owes them and liquidity risk if they have already released funds to customers. In older systems, a failure could trigger unwinding, where the defaulter's payments are removed and all positions recalculated, potentially causing knock-on failures. Exposure tends to grow through the day as unsettled obligations accumulate.
Modern systems manage these risks with caps and limits on positions, collateral pools, loss-sharing agreements and settlement guarantees. The Principles for Financial Market Infrastructures require final settlement no later than the end of the value date, and intraday or real-time finality where needed to reduce risk. They also require a DNS system to cover the failure of the participant with the largest settlement obligation.
Deferred and immediate settlement compared
| Feature | Deferred settlement | Immediate settlement |
|---|---|---|
| When funds move | At scheduled times | As each instruction is processed |
| Interbank exposure | Builds up until settlement | Little or none once settled |
| Liquidity need | Lower | Higher, unless offset by liquidity-saving features |
| Typical systems | ACH, cards, cheques, DNS systems | RTGS systems such as Fedwire and CHAPS |
Trends
Central banks pushed large-value payments from deferred to real-time settlement in the 1990s and 2000s to reduce systemic risk. Retail systems have followed more slowly. Instant payment schemes give customers immediate funds while some still settle between banks on a deferred basis, and operators have responded by shortening cycles, adding prefunding, or moving to settlement in central bank money in real time. Many systems now take the form of a hybrid settlement system that blends deferred and immediate features.
