Chapter 01 · The loan book
₹2.59 lakh crore lent out by March 2026. To whom?
A loan book is everything a lender has lent that has not yet been paid back. It is not profit and not revenue: it is the money still owed to it, on one day.
The simple version. When someone takes a ₹50 lakh home loan, it sits in IDBI Bank's loan book until it is repaid. Add up every loan it had out on 31 March 2026, from housing loan down, and you get ₹2.59 lakh crore. By 30 Sep 2026 it was ₹2.77 lakh crore.
