The international standard for settlement finality is set at the Bank for International Settlements (BIS) and applied through national law. Part 2 walks through the international anchor first, then the major national regimes that operators of tokenised settlement systems map onto.
The international framework
The international standard sits in the Committee on Payments and Market Infrastructures (CPMI) and International Organization of Securities Commissions (IOSCO) Principles for Financial Market Infrastructures (PFMI), published in 2012 and applied to globally significant payment systems, central securities depositaries (CSDs), securities settlement systems, central counterparties (CCPs), and trade repositories (CPMI-IOSCO PFMI). Principle 8 is the finality principle: a financial market infrastructure should provide clear and certain final settlement, at a minimum by the end of the value date, ideally intraday or in real time. Principle 1 covers legal basis. The rest of the cluster covers credit, liquidity, governance and operational risk.
The PFMIs are not law. They are standards. Each jurisdiction translates them into law through its own designation regime, with the result that the underlying expectation is global while the legal mechanics differ. The BIS Innovation Hub under Hyun Song Shin and Tommaso Mancini-Griffoli has extended the framing to tokenised settlement systems and unified-ledger designs that may span multiple jurisdictions (BIS Annual Economic Report 2024 Ch III). The CPMI-IOSCO application of the PFMIs to stablecoin arrangements, published in 2022, is the closest the international standards have come to addressing tokenised cash arrangements directly (CPMI-IOSCO stablecoin application).
ISO 20022 enters indirectly. The migration across SWIFT, T2, CHAPS, Fedwire, and the major Asian real-time gross settlement (RTGS) systems through 2022 to 2025 matters here because finality is increasingly determined by parsing structured fields in the message, with the legal status of those fields under each finality regime something operators have to settle.
The major national finality regimes
The European Union's Settlement Finality Directive (SFD), 98/26/EC, in force since 1999 and amended several times since, is the foundation document for how the modern world thinks about finality (EU SFD). It applies to designated payment and securities settlement systems within the EU. Once a system is designated, transfer orders entered into the system are legally final under the rules of the system, and the protection is enforced against the insolvency of any participant: the liquidator cannot retrospectively unwind transfers, collateral provided to the system is protected, and the zero hour rule is disapplied. The Directive is implemented through national legislation in each member state.
The English Settlement Finality Regulations (SFR) 1999, statutory instrument 1999/2979, implement the Directive into UK law and continue in force after Brexit (UK SFR 1999). The regulations operate through designation by HM Treasury or the Bank of England (BoE), depending on the system type, and apply to designated payment systems such as CHAPS, designated securities settlement systems such as CREST, and embedded systems within central counterparties such as LCH and ICE Clear Europe. The BoE maintains a public list of designated payment systems under its supervisory remit (BoE FMI supervision).
In the United States, there is no single SFD analogue. Finality flows from a combination of statutory provisions and Federal Reserve regulation. Uniform Commercial Code (UCC) Article 4A, adopted in every state, governs the legal characteristics of wholesale credit transfers, including the timing of payment finality. UCC Article 8 governs investment property and the indirect holding system. The 2022 UCC amendments added Article 12, the controllable electronic record category that supports tokenised property characterisation, covered in Tokenisation, defined. The Federal Reserve's Regulation J governs Fedwire, including the moment of finality for funds transfers passing through it (Federal Reserve Regulation J). Fedwire transfers achieve finality at the moment the receiving institution's account is credited, with no zero hour exposure.
In Hong Kong, the finality regime sits within the Payment Systems and Stored Value Facilities Ordinance, which gives the Hong Kong Monetary Authority (HKMA) designation power over payment systems (HK PSSVFO). CHATS, the Hong Kong RTGS, is designated, with finality protected under the Ordinance once a transfer order is processed. The Securities and Futures Ordinance and the Securities and Futures (Clearing Houses) Rules cover designated securities clearing and settlement systems.
In Singapore, finality runs across three statutes. The Payment Services Act covers payment systems and digital payment token services. The Securities and Futures Act covers securities settlement systems and approved clearing houses. The Payment and Settlement Systems (Finality and Netting) Act provides the cross-cutting finality regime, including the protection of designated systems against insolvency clawback and the validity of netting arrangements within designated systems (Singapore PSSFNA). The Monetary Authority of Singapore (MAS) designates systems under the framework. MEPS+, the Singapore dollar RTGS, and the major retail and securities settlement systems are designated.
In Japan, the finality framework runs through the Banking Act and the Payment Services Act, with subsidiary regulations under the Financial Services Agency (FSA). The Bank of Japan operates BOJ-NET under the Bank of Japan's own legal authority. Securities settlement runs through separate statutory and operating-rule arrangements, with JSCC as the central counterparty for listed derivatives. The Japanese architecture is less codified into a single finality statute than the EU model and more dispersed across instrument-specific regimes.
Designation: the legal hook
Designation is the act by which a competent authority brings a payment or settlement system within the scope of a finality regime. The form differs by jurisdiction, ministerial order in some, regulator notice in others, but the substance is uniform. Once designated, transfers within the system inherit insolvency-protected finality. Without designation, a system relies on contractual arrangements among participants and the underlying law of the jurisdiction, which may or may not yield the same protection.
What the authority looks at when designating a system. The legal soundness of the system rules. The robustness of the operational infrastructure. The risk management and access criteria. The systemic significance of the flows passing through. The fit with PFMI principles where the system is large enough to matter at the international level.
Examples. CHAPS, CHATS in hong kong, MEPS+ in Singapore, BOJ-NET in japan, T2 in the eurozone, Fedwire under Regulation J in the US. Designated securities settlement systems include CREST, Euroclear, Clearstream, the major APAC CSDs, and the embedded settlement systems within CCPs such as LCH, ICE Clear, and JSCC.
