Deposits grew 24.8 per cent, while overall advances grew 21.8 per cent, while total income rose to Rs 13,894.7 crore from Rs 11,937.7 crore.
However, the bank exceeded its own forecast on the key net interest margin, which expanded to 4.5 per cent as against the general guidance of 3.9-4.2 per cent.
On the future trajectory of margins, he said the bank will maintain it in the 4-4.4 per cent range.
Asked about the lending rates, especially in the wake of the bank exceeding its guidance on margins and rival Axis Bank cutting its base rate by 10 bps last week, Sukthankar said HDFC Bank has not taken a call yet and is comfortably placed on liquidity.
He further said the base rate is a function of the deposit rates, which are in turn guided by the liquidity position.
He said a GDP growth of over 5.5 per cent will result in the system's credit growth, which has barely breached the double digit mark this fiscal, growing to 12-13 per cent and the bank shall outpace the system by 4-5 per cent.
Demand from corporates for greenfield projects is yet to come in and Sukthankar said the same is a few quarters away, adding its corporate book growth came in form of working capital loans and some medium term loans.
