The Three Pillars of Basel III
The Basel III accord is structured around three mutually reinforcing pillars designed to strengthen bank resilience and capital buffers:
Pillar 1: Minimum Capital
Defines minimum regulatory requirements for Credit, Market, and Operational Risk capital charges.
Pillar 2: Supervisory Review
Requires banks to perform internal capital adequacy assessments (ICAAP) and evaluates risk control efficacy.
Pillar 3: Market Discipline
Mandates detailed public disclosures on risk exposures, capital structures, and credit safety margins.
Regulatory Capital Tiers & Thresholds (RBI Rules)
Under RBI's implementation of Basel III guidelines, commercial banks in India are required to maintain a minimum Capital-to-Risk-Weighted-Assets Ratio (CRAR) of 9% (Basel minimum) plus a 2.5% Capital Conservation Buffer (CCB) = 11.5% in total:
| Capital Tier | Minimum Ratio | Minimum Ratio + 2.5% CCB |
|---|---|---|
| Common Equity Tier 1 (CET1) | 5.5% | 8.0% |
| Tier 1 Capital (CET1 + AT1) | 7.0% | 9.5% |
| Total Capital (CRAR) | 9.0% | 11.5% |
