1.1 Defining Payment Systems
A payment system is the set of instruments, banking procedures, and interbank funds transfer systems that ensure the circulation of money within an economy . It is the essential infrastructure that enables financial transactions between payers and beneficiaries. Payment systems are a major channel by which financial shocks can be transmitted across domestic and international markets .
1.2 Key Participants and Components
Every national payment system consists of several key participants :
-
The Central Bank:Â The primary overseer, operator of critical infrastructure, and provider of settlement accounts.
-
Commercial Banks and Financial Institutions:Â The primary users of the system on behalf of their customers.
-
Payment System Providers:Â Non-bank entities authorized to provide payment services.
-
The Government:Â A major user for its own transactions.
-
Customers:Â Both individuals and businesses who initiate and receive payments.
Payment systems are a critical component of a country’s financial system and are often categorized into Large Value (Wholesale) and Low Value (Retail) Payment Systems . Understanding the framework is crucial for analyzing how funds move securely through banking networks .
1.3 The Role of Central Banks
Central banks play a central, multi-faceted role in ensuring the soundness and efficiency of payment systems . Their functions include :
-
Overseer:Â To promote efficiency and soundness.
-
Supervisor:Â To maintain integrity and confidence in the system.
-
Facilitator of Settlement:Â By providing settlement accounts to commercial banks.
-
Provider:Â Operating key systems like RTGS.
-
User:Â For their own transactions.
-
Provider of Liquidity:Â To facilitate efficient settlement.

Central banks seek to ensure payment systems do not generate high levels of risk, continue to operate without major disruptions, and offer efficient, reliable, and safe services .
