What does the term 'Liquidity' refer to in payment systems?

The term 'Liquidity' in payment systems primarily refers to the availability of adequate money or balances that a payment participant maintains in their settlement account. This aspect of liquidity is critical because it ensures that transactions can be executed promptly and efficiently without delays or issues related to insufficient funds.

In a payment system context, having sufficient liquidity means that a participant can meet their payment obligations as they arise, allowing for smooth financial operations and minimizing risks associated with payment delays. This capability is essential for maintaining trust and reliability within payment systems, as participants must be able to access funds as needed to complete transactions.

While liquidity can also be understood more broadly, such as the general concept of converting assets to cash quickly, in the specific context of payment systems, it is about the cash available in settlement accounts that facilitates immediate payments.
