"Obviously, if more and more positive news on inflation front comes, it's a reasonable expectation to expect that rates will be cut at the September policy," HDFC Bank's managing director Aditya Puri told reporters outside RBI here.
He said Governor Raghuram Rajan had earlier said that the RBI is "actively looking" at a rate cut.
State-run Bank of India's chief executive and managing director B P Sharma said bankers have always been asking for a rate cut and the lower inflation reading only heightens their hopes.
It can be noted that after it turned confident on the inflation front early this year, the RBI cut its key rates by 0.75 per cent in 2015.

Apart from further softening in inflation, the RBI said transmission of its policy rates into lending by banks, impact of the monsoons and the US Fed's stance will be the key factors it will look out for.
On transmission, where the RBI says banks have passed only 0.30 per cent in their lending rates as against its 0.75 per cent in cuts, Puri conceded that more rate cuts are required.
A base rate cut is possible only after the cost of deposits come down, he added.
Retail inflation fell to multi-year low of 3.78 per cent in July on account of cheaper food prices, including of vegetables, fruits and cereals.
The retail inflation based on Consumer Price Index (CPI) was at 5.40 per cent in June 2015. In July 2014, CPI based retail inflation was as high as 7.39 per cent.
Puri and Sharma were speaking to reporters post a luncheon meet at the central bank after annual board meet.
Other bankers who were present included SBI's chairman Arundhati Bhattacharya, ICICI Bank's Chanda Kochhar, Shikha Sharma of Axis Bank and Uday Kotak.
