Payment infrastructure design requires a systematic approach to identifying and mitigating technical and financial failures. Risks within a processing loop are classified into five distinct operational domains:
[Payment System Risk Domains]
|- 1. Credit Risk ------> The threat that a participant bank defaults before settling its gross debts
|- 2. Liquidity Risk ---> The risk that a bank lacks sufficient reserves to clear on-time transfers
|- 3. Operational Risk -> System downtime, software bugs, or cyberattacks disrupting processing
|- 4. Legal Risk -------> Lack of enforceable contracts or court rulings overturning transactions
|- 5. Systemic Risk ----> A single bank failure triggering a domino collapse across the network
To achieve system resiliency, central banks mandate that platforms isolate these risks, implementing automated collateral checks and real-time settlement tracking to prevent localized shocks from spreading.
