Bank Valuation Simplified.
Understanding the metrics that matter for Indian banks
Imagine you lent money to a friend who promised to return it with interest. But what if your friend's business went bust? A bank is like that friend, but with safeguards. Let's see how it works.
A bank takes deposits and lends them out. Its equity is the safety cushion that protects your deposits.
P/BV is a key metric; it shows the premium over the bank's book value. A high RoE justifies a high P/BV.
GNPA reveals bad loans. High GNPA eats away at the safety cushion.
CASA deposits are cheap and sticky, reducing borrowing costs. NIM is the lending spread, the gap between loan and deposit interest.
Banks like Chai Businesses
Just as a fancy cafe and a tapri have different profit margins, banks with different RoE are like two chai businesses turning rupee into profit differently.
Why this matters
Understanding bank valuation helps you make informed decisions about your investments. You can assess the safety cushion and potential returns.
Try moving the sliders to see how RoE and GNPA impact P/BV.
What justifies the P/BV premium?
A bank with 15% RoE and 3% GNPA justifies a 2.1x P/BV. High RoE builds the equity cushion; high GNPA eats it. Drag the sliders to watch the premium appear or vanish.
Where people go wrong

- Ignoring GNPAHigh GNPA eats away at the safety cushion.

CASA ratio impacts borrowing costs and NIM
People often buy low P/BV banks hoping for a turnaround, confusing a cheap price with a genuine margin of safety.
