The main distinction is when obligations are settled. In real-time settlement, each payment obligation is settled individually as it is processed. Under netting, obligations are combined so participating banks settle their resulting net positions collectively. This difference affects the timing of funds movement and the liquidity banks must manage while payments move through the financial system.
Central bank balances provide a commonly used basis for final settlement, allowing participating banks to complete obligations through balances held at the central bank. Their role links payment processing with banks’ liquidity management because institutions must have sufficient funds available for settlement. This makes central-bank settlement relevant to payment continuity and the functioning of the wider banking system.
Clearing arrangements, correspondent accounts, and payment systems organize the path from one bank to another through different institutional channels. Clearing arrangements can establish obligations for settlement, while correspondent accounts support transfers between banks through account relationships. Payment systems provide the means through which these transactions are processed, helping connect separate institutions within one financial network.
Interbank payments transmit monetary policy because they connect banks’ liquidity management with financial-market activity and the broader economy. As banks manage funds needed to complete obligations, payment flows provide a channel through which policy conditions can affect the financial system. The macroeconomic relevance lies in this connection between settlement activity, market functioning, and economic transactions.
Processing generally moves from a transfer entering an applicable clearing arrangement, correspondent account, or payment system to settlement between the banks. The obligation may be completed individually in real time or combined with others for net settlement. Where central-bank balances are used, the process concludes with settlement through those balances, supporting completion across the network.
Interbank payments matter whenever separate institutions must settle transactions, including activity involving businesses, households, governments, and financial institutions. They connect these users to the banking network rather than operating only within one bank. Their macroeconomic importance comes from supporting payment efficiency and linking financial-market operations with the economic activity those transactions represent.
Speed and reliability influence how efficiently obligations are completed, while resilience concerns whether the payment network continues to function under strain. Weakness in these characteristics can increase systemic risk because banks are connected through shared payment flows. Strong performance, by contrast, supports stability in the broader banking system and helps transactions proceed across financial markets.
