Transaction Settlement

Overview

Transaction settlement is the completion of the funds or asset movement that discharges the financial obligation created by a transaction. It may occur individually or as part of a netted or batched settlement. The customer transaction and its inter-participant settlement may have different amounts, references, and timing.

It can occur in central bank accounts, commercial bank accounts, a securities system, an internal ledger, or a blockchain, depending on the arrangement. Operational systems must therefore preserve the allocation between the customer event and the settlement movement. Finality rules determine when the settlement can no longer be revoked under the governing system. The operational record should capture obligation, participant, gross or net position, settlement asset, account, liquidity source, value date, and finality evidence for Transaction Settlement, including the handoff to Settlement Asset .

Transaction Settlement should remain distinct from Settlement Asset and Settlement, because each can represent a different stage, record, control, or financial outcome. Fees, reserves, foreign exchange, netting, and batching can cause one settlement entry to represent many transactions or only part of one transaction.

For Transaction Settlement, the failure model should include incorrect obligations, liquidity shortfalls, participant default, wrong settlement assets, premature finality, and unreconciled movements. Important failure modes include insufficient liquidity, duplicate instructions, wrong settlement assets, delayed delivery, participant default, unmatched evidence, and premature claims of finality.

Settlement should be distinguished from authorization, clearing, and a provider success response. Controls should validate instructions, funding, destination, currency or asset, cutoffs, and participant positions before treating a settlement step as complete.
