Payment finality is the legally recognized point at which a transfer of an asset or the discharge of an obligation becomes irrevocable and unconditional under the applicable rules and legal framework.
Financial market infrastructure standards generally use the term settlement finality for this concept. In stablecoin arrangements, the legal point of finality can differ from the state of the distributed ledger. A network may reach technical settlement according to its consensus rules while the legal framework defines finality differently. CPMI-IOSCO requires systemically important stablecoin arrangements to define final settlement clearly and address possible misalignment between the ledger state and legal finality.
Transaction confirmation and technical settlement describe states of the network or ledger. Payment finality concerns the point at which the transfer or discharge is legally irrevocable and unconditional.
Finality determines when the parties can rely on settlement as complete and when the relevant settlement exposure has ended.
A merchant can wait for a network-defined level of confirmation before releasing goods, while the legally final point of settlement may be determined by separate system rules or law.
