### Risk Assessment

- **[CATALYST] SEBI/RBI Governance Regulatory Action** (NEUTRAL, Risk: MODERATE): This risk is STABLE but highlighted as a critical vulnerability; management admitted that while digital systems are strong, physical 'eye-to-eye' checks were compromised by internal collusion. (1 stable)

  > 14% of total loan book is Unsecured Retail Credit GNPA = 1.48% NNPA = 0.45%
- LCR improved to 117% from 114% in the previous quarter. While new regulatory guidelines on runoff factors may pose a 1-2% headwind, the overall trajectory is stable to improving. (2 stable, 1 high-severity) (NEGATIVE, Risk: MODERATE)
  > This is a physical transaction where people have come, you know, the cheques have been forged... obviously happened with the connivance of employees. There is maker, checker, authorizer, the whole system exists, but obviously with some bunch of people have come together to make it happen.
