"Whatever assumptions we made in terms of oil prices and other commodity prices, subsequently what we see now is that the prices have come off even more. So, the disinflationary process would see a bit stronger than what the last policy had done," Mohanty, whose remit includes the crucial monetary policy department, said at a conference.
The price of Indian crude basket has fallen to a low of around USD 81 a barrel as against USD 108.05 in May end.
He had said the target of getting consumer price inflation to 8 per cent by January 2015 was more certain, while the risks to the January 2016 target of 6 per cent had subsided.
It can be noted that the RBI has been very vocal with its resolve to contain inflation in a decisive manner and has been holding on to elevated rates to achieve this objective even at the cost of criticism from the pro-growth lobby, which wants a rate cut.
Mohanty said the lower crude prices, coupled with a stable currency has helped reduce the inflation. However, he expressed caution, saying we should not be "overly joyous" stating that the 6.46 per cent number will rise further soon.
"There is a base effect in that and we should not be overly joyous over the fact that we are at 6.5 per cent, but it could slightly go up as we go down the line," he said.
