Central Bank Money

Overview

Central Bank Money is money that is a direct liability of a central bank, including banknotes and central bank reserve balances used for settlement. In a payment system, teams should identify the form and access model, understand operating hours and finality, and distinguish settlement in central bank money from claims on private institutions. Central bank money is a direct central bank liability; commercial bank money is a claim on a private bank.

Central Bank Money is closely connected to Commercial Bank Money , Payment Settlement Risk , and Clearing House Interbank Payments System (CHIPS) . Both may be denominated in the same currency while carrying different access, credit, liquidity, and operational characteristics. Operationally, the implementation should identify the form and access model, understand operating hours and finality, and distinguish settlement in central bank money from claims on private institutions. Scenario analysis should include bank outage or resolution, restricted access to reserves, conversion between forms of money, intraday liquidity stress, payment-system closure, and loss of confidence in par convertibility.

Central Bank Money should remain distinct from Commercial Bank Money, Payment Settlement Risk, and Clearing House Interbank Payments System (CHIPS), because each can represent a different stage, record, control, or financial outcome.

Useful measures include balances by issuer and form, concentration, settlement-asset usage, intraday liquidity, conversion delays, counterparty limits, and exposure during system outages. Important failure modes include duplicate or delayed events, wrong destinations or currencies, stale instructions, unavailable providers, unsupported retries, and customer-facing status that differs from authoritative records.
