Settlement Instruction ID

Overview

Settlement Instruction ID is a unique identifier assigned to a settlement instruction for tracking, deduplication, status inquiry, and reconciliation. It identifies the instruction and should remain stable across status inquiries and retries that refer to the same intent.

Settlement Instruction ID is closely connected to Settlement Instruction Status , Settlement Instruction Validation , and Payout Processing Pipeline . The implementation should identify the obligation, participants, settlement asset, accounts or addresses, value date, liquidity source, posting sequence, and evidence of finality.

Settlement Instruction ID should remain distinct from Settlement Instruction Status, Settlement Instruction Validation, and Payout Processing Pipeline, because each can represent a different stage, record, control, or financial outcome.

Important failure modes include insufficient liquidity, duplicate instructions, wrong settlement assets, delayed delivery, participant default, unmatched evidence, and premature claims of finality. For Settlement Instruction ID, this point supports the definition’s focus on unique identifier assigned to a settlement instruction for tracking, deduplication, status inquiry, and reconciliation.
