“Stable balance sheet growth of ~20%”
The bank successfully reduced credit costs to 2.05% in Q3 FY26, hitting the lower end of the full-year guidance range. (2 met across 2 tracked commitments)
“And our overall guidance on credit cost still stays around that 2.05%, 2.1%, which we had guided in the previous quarter. H1 credit cost, if you put together, it's about 2.45%. So definitely, because we are anticipating a lower stress going forward, the credit cost in H2 will be much lower to that number of 2.05% to 2.1%.”
