This is well known - HDFC Bank and Kotak are more the exceptions in the Indian banking game. Well, I am not as sure about Kotak, but HDFC Bank is clearly an outlier.
But then, it is one thing to claim that Yes Bank lends more aggressively - and another thing to claim that the management is hiding / misreporting NPAs.
Aggressive lending doesn’t always convert into NPAs - because of better collaterals, or favorable loan agreements, or lending to group entities with better cash flows, etc etc.
In case of an economic recession/depression, Yes Bank’s books will be in more trouble than those of peers like HDFC. But during normal times, I think Yes Bank’s books tend to be as good as those of HDFC - at least that is the experience so far…
