The settlement discipline regime is a body of European Union rules designed to make securities trades settle on time. It forms part of the Central Securities Depositories Regulation (CSDR), adopted in 2014, and combines measures intended to prevent settlement fails with measures that apply once a fail has occurred. It affects every firm in the settlement chain: trading parties, brokers, custodians, central counterparties and each central securities depository in the European Economic Area.
The regime exists because a settlement failure has costs beyond the two parties involved. A seller that delivers late can cause the buyer to fail on its own onward delivery, and chains of fails tie up collateral and add risk. Before the regime, penalty arrangements differed from market to market. The detailed rules took effect on 1 February 2022, after several postponements.
Measures to prevent fails
The first group of rules is aimed at getting instructions right before the intended settlement date:
- Allocation and confirmation. Investment firms must have arrangements with professional clients for prompt trade allocation and trade confirmation, with deadlines on the trade date or shortly after.
- Matching. Depositories must offer automated, continuous settlement instruction matching and standard matching fields.
- Tolerance levels. Small differences in cash amounts are ignored within set limits so that trivial mismatches do not block settlement.
- Hold and release, and partial settlement. Depositories must provide tools to hold an instruction back and to allow partial settlement when only part of the securities is available.
- Monitoring and reporting. Depositories track fails, report them to regulators and work with participants that fail persistently.
Cash penalties
The second group applies once a matched instruction has not settled on its intended date. The depository calculates a settlement penalty for each business day the instruction remains unsettled. The penalty is charged to the participant responsible for the fail and credited to the participant that suffered it, so the depository does not keep the money. Rates are set in EU rules and vary by type of instrument, with higher rates for liquid shares than for bonds. A separate penalty applies where instructions are matched only after the intended settlement date.
Penalties are calculated daily and collected and distributed monthly. Participants then pass the amounts down to their own clients, which has required custodians and brokers to build processes for allocating, reporting and disputing penalties. Trades cleared through a central counterparty follow adapted collection arrangements.
Mandatory buy-ins
The original regulation also provided for mandatory buy-ins. If securities were still undelivered a set number of days after the intended date, the buyer would have been obliged to start a buy-in procedure, purchasing the securities elsewhere at the failing seller's expense. This element was strongly contested by market participants, who argued that it would reduce liquidity, especially in bonds and less-traded shares.
The buy-in rules were not brought into force with the rest of the regime in 2022. A review of the regulation, known as CSDR Refit and adopted in 2023, recast mandatory buy-ins as a measure of last resort that the European Commission can switch on only if penalties have not reduced fails sufficiently and fail rates threaten financial stability. Contractual buy-ins under market rules and trading agreements continue to be available.
Effect on operations
The regime turned settlement efficiency into a direct financial cost. Firms responded by improving settlement fail management: checking inventory before settlement date, pre-matching instructions, borrowing securities to cover shortfalls and using partial settlement more widely. Teams responsible for fails repair prioritise items by expected penalty. Standing settlement instructions and reference data have received more attention because many fails begin with incorrect account details.
Penalty statements must be reconciled each month, and firms need rules on whether small amounts are passed to clients. Activity settled at an international central securities depository established in the EU falls within scope, wherever the trading parties are based.
Later developments
The United Kingdom did not adopt the settlement discipline rules when it kept the rest of the regulation in domestic law after leaving the EU, so penalties of this kind do not apply at the UK depository. Within the EU, the supervisory authority for securities markets has reviewed the penalty mechanism and rates. The planned shortening of the EU settlement cycle to one business day after the trade, scheduled for October 2027, leaves less time to correct problems before a penalty starts to accrue, and further changes to the regime have been proposed to support that move.
