The country's largest private bank had reported net profit of Rs 1,815.05 crore in the year-ago period.
It booked a Rs 403 crore income from treasury operations in the first quarter of 2013-14, as against Rs 21-crore loss in the year-ago period, which was the major reason for the spike in overall profit.
A healthy 20 per cent spurt in key net interest income, which is the difference between interest paid and interest earned, at Rs 3,820 crore during the quarter pushed up the total income of the bank 13 per cent to Rs 12,905 crore.
This has had a positive impact on the net interest margin (NIM), which is a key gauge of profitability for banks, pushing it up to 3.27 per cent in the quarter from 3.01 per cent a year ago, ICICI Bank Managing Director and chief executive Chanda Kochhar told reporters at a conference call.

The domestic margins stood at higher 3.63 per cent in the quarter, she said.
Kochhar also attributed the good set of numbers to a sharp spurt in dividend and non-interest incomes as well as treasury incomes.
Dividend and other incomes rose to Rs 288 crore from Rs 254 crore, out which treasury income was Rs 403 crore from a loss of Rs 21 crore a year back.
The market however did not lap up the numbers and the bank scrip lost more than 2 per cent to close at Rs 907.50 on the BSE, pulling down the Bankex by 1.84 per cent to 11,440.96 points. The benchmark BSE Sensex closed flat with a negative bias.
