What does the term 'settlement finality' refer to?

The term 'settlement finality' refers to the point at which the transfer of an asset becomes irrevocable, meaning that once it occurs, it cannot be reversed or undone. This concept is crucial in payment systems and financial markets because it provides certainty to both parties involved in a transaction. When settlement finality is established, it reassures participants that their transactions are complete and legally binding.

Understanding settlement finality is important as it helps prevent disputes and reduces systemic risk in financial transactions. For instance, when a payment has been settled, it confirms that the receiving party has clear ownership, and the sender no longer has any claim to the asset. This finality is essential in establishing trust and reliability in electronic payment systems.

In contrast, the other options relate to different concepts that do not capture the essence of settlement finality. For example, a transaction being reversed pertains to the process of canceling a payment, while the period for disputing payments focuses on the timeframe within which a claim about a transaction can be made. The final balance of a payment account is simply a statement of the current state of funds and does not address the irrevocable nature of completed transactions.
