Falling food prices helped cool India's consumer inflation rate to 3.17%in January year-on-year, the mildest reading in at least five years and well below the Reserve Bank of India's medium-term target of 4%.
But core inflation accelerated to around 5.1% pointing to building price pressures in the broader economy.
India's wholesale prices rose at the fastest pace in two-and-a-half years in January as fuel prices climbed, reinforcing the Reserve Bank of India's surprise decision last week to move to a neutral policy stance as inflation risks grow.
"We also find commodity prices have firmed up globally," Patel said, in an initial snippet of the interview that aired early on Friday.
Global crude oil prices are up more than 23% since mid-November.
The RBI is expected to keep interest rates on hold until at least the second half of next year, according to a Reuters snap poll taken after earlier this month after the central bank's change in policy stance.
Patel has faced some criticism from bankers for not adequately guiding the markets on the central bank's thinking, especially after it abruptly shifted its stance from "accommodative" last week.
"The committee felt that inflation excluding food and fuel is something that has been stubborn since September-October and has shown little sign of coming decisively below 5 and that was the main reason why we had to look through headline inflation," Patel said.
Asia's third-largest economy is still limping back to health after Prime Minister Narendra Modi's November 8 decision to outlaw old 500- and 1,000- rupee banknotes wiped out 86% of the currency in circulation overnight.
The move dampened consumer and corporate demand, sending prices lower, though activity is slowly returning to normal.
Patel said the RBI's monetary policy committee will continue to monitor how long the disinflationary pulse from the cash crackdown will last.
"It's most likely going to be short-lived," he told CNBC.
"That was the reason that MPC thought that we needed to have flexibility going forward, therefore the shift of stance form accommodative to neutral".
