Swap Reconciliation

Overview

Swap reconciliation verifies that an asset or currency swap was quoted, executed, settled, and recorded correctly across orders, fills, balances, fees, rates, and counterparties. It explains differences between expected and realized exchange outcomes. Reconciliation confirms conservation of value within the defined accounting method and assigns every residual amount.

It then compares actual fills, execution prices, fees, transferred quantities, settlement movements, and ledger entries. The system should retain each fill and conversion step rather than replacing them with one calculated average without source evidence. Teams should design for missing records, false matches, wrong cutoffs, inconsistent currencies, hidden exceptions, and unsupported manual corrections. The operating record should identify the source population, counterpart data, matching rule, cutoff, amount or value, tolerance, exception reason, owner, and resolution evidence. Controls should keep original source records immutable, use stable match keys, explain many-to-one or one-to-many relationships, and route unresolved differences to an aged exception queue.

Swap Reconciliation should remain distinct from Reconciliation and Reconciliation Exception, because each can represent a different stage, record, control, or financial outcome.

Partial fills, multiple venues, rounding, network fees, slippage, failed legs, and delayed settlement can produce legitimate differences. Important failure modes include missing records, duplicate matches, timing differences, hidden fees, currency mismatches, stale files, and adjustments that force balances to agree without explaining the cause.

On-chain swaps also require verification of network, contract, transaction, token addresses, decimals, and finality. Unmatched or out-of-tolerance results should remain exceptions until corrected or approved. For Swap Reconciliation, the authoritative record and completion rule should be documented before any irreversible operational, customer, or accounting action is released.
