- **[METRIC] Net Interest Margin** (NEGATIVE, Risk: MODERATE): NIM has compressed further to 5.71% from 5.95% in the previous quarter, intensified by the passing on of repo rate cuts to customers while deposit repricing lags. (3 intensifying, 2 easing)
  > In FY25 and FY26, the NIM reduced from the peak levels due to drastic reduction of Micro-finance book due to the industry crisis.
- **[METRIC] Return on Equity ROE** (NEGATIVE, Risk: MODERATE): The CET-1 ratio fell further to 12.80% this quarter, primarily due to a re-assessment of Operational Risk Risk-Weighted Assets (RWA). (2 intensifying, 1 stable)
  > Overall Bank C:I ratio Trend: (excl. trading gain) 73.5%
- **[METRIC] Gross NPA and Slippage Ratio** (NEGATIVE, Risk: HIGH): The risk is easing as the MFI loan book has been aggressively reduced to just 3.3% of total funded assets, and collection efficiency has improved to 99.0%. (5 easing, 1 high-severity)

- **[PRINCIPLE] Technology and Digital Banking Leadership** (POSITIVE): The C:I ratio remains high at 74% (excluding trading gains), showing a slight increase from the previous year's average, though management targets a reduction to 65% by FY27. (4 stable, 1 easing)
  > Overall Bank C:I ratio Trend: (excl. trading gain) ... Q1FY26 74%. At an overall Bank level, the C:I planned to improve to ~65% by FY27 because of scale.
- **[PRINCIPLE] Management Quality and Governance Standards** (NEGATIVE, Risk: HIGH): A new, specific fraud incident involving employee collusion at a Chandigarh branch has been identified, with a total estimated financial impact of INR 590 crores. This is an isolated but significant operational risk event. (1 intensifying, 1 resolved, 1 high-severity)

  > CET-1 Ratio (%) Mar-26 13.73% [vs] Dec-25 14.23%

### Scenario Analysis

- The bank's deployment of AI for underwriting and diagnostics (first-order) allows it to penetrate the MSME and personal finance segments with granular risk-adjusted yields exceeding 11%. This leads to a second-order reduction in cost-to-serve, as evidenced by business growth (18.6%) significantly outpacing opex growth (12.3%). Ultimately, this results in a third-order shift in sector leadership, where the bank converts its proprietary data and digital process depth into superior market share in high-velocity credit products. (POSITIVE)
  > This is further improved with the advanced use of Indian digital ecosystems and specialized credit controls. IDFC is a digitally advanced bank and is able to lend to these segments in a controlled manner.
- The Iran conflict's first-order impact on crude prices and the rupee directly increases demand for the bank's forex hedging and trade finance solutions, which comprise 10% of fee income. As the oil shock forces the RBI to maintain higher interest rates (second-order), the bank's successful reduction of its cost of funds to 6.11% allows it to maintain margins better than peers. Ultimately, the bank's near-zero exposure to infrastructure prevents third-order fiscal slippage from the government's rising subsidy bill from impacting its balance sheet, a major historical pain point now resolved. (POSITIVE)
  > Cost of Funds (Q4-FY26) 6.00% (-51 bps YoY | -11 bps QoQ)
