Basel Approaches for ORC

Approach	Full Name	How It Works (Simple Explanation)
BIA	Basic Indicator Approach	Uses gross income as a proxy for operational risk. Capital = 15% × 3-year average gross income.
TSA	Standardised Approach	Applies different percentage factors to income across business lines.
AMA	Advanced Measurement Approach	Uses internal models based on historical losses, scenarios, and internal controls.
SMA	Standardised Measurement Approach	Combines the Business Indicator Component (BIC) with the Internal Loss Multiplier (ILM). Capital = BIC × ILM.

Approach	Data Required	Pros	Cons
BIA	Only financial statements (gross income).	Simple, fast, very low effort.	Not risk-sensitive; income does not reflect operational risk.
TSA	Financial statements + business line allocation.	More risk-sensitive than BIA; structured.	Still income-based; weak link to real losses.
AMA	Large internal loss database, scenario analysis, internal models.	Highly risk-sensitive and tailored.	Very complex and costly
SMA	Financial statements + 10 years of operational loss data.	Balanced, transparent, globally adopted; rewards strong data quality.	Requires disciplined loss reporting and clean data.
