Settlement Cycle

A settlement cycle is the pattern on which a payment system, market or provider settles transactions. The term has two closely related meanings. It can describe the recurring schedule of settlement runs, such as a card network settling once per business day or an automated clearing house settling several times a day. It can also describe the length of time between the moment a transaction is agreed and the moment it is finally settled, written in securities and foreign exchange markets as trade date plus a number of business days, such as T+1 or T+2. Some systems settle several times during the day, which is known as intraday settlement.

Settlement cycles determine how long money or assets are in transit and how long participants are exposed to each other. Shorter cycles reduce settlement risk and free up capital, while longer ones give time for checks, corrections and funding. The cycle is related to, but different from, the settlement cut-off, which is the deadline for entering a given cycle, and the settlement lag, which describes the delay experienced in practice.

Different payment systems settle on different cycles:

• Card networks. Visa, Mastercard and other networks typically clear transactions in daily cycles and settle net positions with issuers and acquirers once per business day, or in several windows. Merchants are then paid on their acquirer's own merchant settlement cycle, which may be next day, two days later or longer for higher-risk businesses.
• Automated clearing houses. ACH systems settle in batches at scheduled times. The US ACH network has same-day and next-day cycles, while other countries' systems may settle once or several times per day.
• Real-time gross settlement. In an RTGS system, each payment settles individually, so there is no cycle in the batch sense, only the system's operating day.
• Instant payment systems. Customer payments complete in seconds, but interbank settlement may be immediate in central bank money or may follow periodic deferred net settlement with prefunded positions.

In securities markets the settlement cycle is the number of business days between trade and settlement. Over several decades, major markets have shortened it, from five business days to three, then to two, and the United States, Canada and Mexico moved most equity and corporate bond trades to T+1 in May 2024. The European Union, the United Kingdom and Switzerland have announced plans to move to T+1 in October 2027. Settlement takes place through a central securities depository on a delivery versus payment basis.

Spot foreign exchange trades in most currency pairs settle two business days after the trade date, with some pairs, such as US dollar against Canadian dollar, settling one day after. Settlement of many FX trades runs through Continuous Linked Settlement, which settles both legs simultaneously to remove the risk that one side pays and the other does not.

The time between agreement and settlement creates exposure. If one party fails before settlement, the other may lose the value of the trade or have to replace it at a worse price. Clearing houses and central counterparties manage this by collecting margin, which grows with the length of the cycle. In payments, longer cycles mean merchants wait for their money and providers carry more credit exposure to merchants who might fail before refunds and chargebacks are covered.

Shorter cycles reduce these risks but require faster processing, earlier funding and more automated exception handling. Market participants moving to T+1, for example, had to compress trade confirmation, allocation and foreign exchange funding into much less time, particularly for investors in other time zones.

Settlement cycles are set by system rules, market conventions and contracts. Payment providers may offer faster settlement for a fee, while acquirers may lengthen a merchant's cycle or add a reserve if risk rises. In markets, changes to the standard cycle are coordinated by regulators and industry bodies because every participant must change at the same time. Technology such as distributed ledgers and tokenised assets has prompted proposals for same-day or instant settlement, though these raise questions about liquidity and the ability to net transactions.

Faster cycles can also reduce the benefits of netting. When transactions settle less often, many payments in opposite directions cancel out before money moves; when each settles almost immediately, participants need more liquidity on hand. System designers therefore weigh speed against the funding burden placed on participants.
