Altman Z-Score Flags Canara, Bank of India & Union Bank

Altman Z-Score Distress Zone: What the Numbers Actually Say The Altman Z-Score for [Canara Bank](/stock/CANBK), [Bank of India](/stock/BANKINDIA), and [Union Bank of India](/stock/UNIONBANK) sits in a range of 0.34 to 0.37 — well below the 1.81 threshold that Edward Altman originally defined as the distress zone boundary. On a raw screening basis, that's a red flag. But context matters enormously here, and ignoring it would be a mistake for anyone using this metric to make portfolio decisions on Indian PSU banks. The distress signal is almost entirely a function of debt-to-equity ratios exceeding 11x across all three names. For a manufacturing company or an NBFC, that kind of leverage would warrant serious concern. For a public sector bank, it's structural. Deposits are booked as liabilities, and equity capital is thin by design. The Altman model was built on US industrial firms in the 1960s — it was never calibrated for deposit-taking institutions, and applying it to PSU banks without adjustment produces a reading that's more noise than signal. That said, dismissing the Z-Score entirely would also be wrong. It's a useful screening flag that prompts the right follow-up questions: How clean is the loan book? What's the capital adequacy position? Are provisions adequate? Those questions deserve answers before any buy decision. ROCE, P/E, and What the Market Is Actually Pricing Here's where the picture gets genuinely interesting. All three banks are posting ROCE figures above 6%, which isn't spectacular but is meaningfully positive for state-owned lenders that were deep in NPA trouble as recently as FY2019–20. NSE: CANBK trades at a trailing P/E below 7. NSE: BANKINDIA and NSE: UNIONBANK are in similar territory. The market is not pricing these as growth compounders — it's pricing them as value plays with a risk discount baked in. That risk discount reflects a few real concerns. Gross NPA ratios, while improved, remain elevated relative to private sector peers. C...
