Junking of old Rs 500 and Rs 1000 notes, he said, will help the world's fastest growing major economy to move towards less cash economy and digital payments that will help shore up tax revenues and check evasions.
Besides, restrictions on cash spending together with mandatory furnishing of PAN will help bring down the level of corruption, he said, adding that the transient problems arising from demonetisation are being addressed by rapidly replacing the junked currency with valid banknotes.
Corruption scandals - ranging from 2G spectrum scam to coal block allocation to Commonwealth Games to deal with AugustaWestland for procuring VVIP helicopters - peaked during the UPA regime, he alleged.
"Each of the scandals which is even today discussed in public space belongs to that period. Given this scandalous record, it is not surprising that Congress party is extremely uncomfortable with anti-corruption campaign that the NDA led by Narendra Modi has launched," Jaitley told reporters here.

Demonetisation, he said, is part of the system overhaul by the NDA government.
"It is our strategy that from high cash dominated economy we should become a less cash economy where the amount of paper currency comes down," he said.
As more and more of the new currency comes into
circulation and re-circulated in the banking system, ATMs will make it increasingly available, Jaitley said.
On the advantages of the demonetisation move, he said a large volume of cash has come into the banking system and taxes will be recovered wherever they are not paid.
"Future transactions would be substantially digital and once they are substantially digital they get caught in the tax net. Therefore the future taxation level would be much higher than what is currently being collected," he said.
Also, the banking system will have lot more cash, which will boost it's ability to support economy with low cost lending.
"Obviously with all these advantages the social cost also on the system will go down. Therefore, the cash used for bribery, for counterfeit currency, for terrorism, for evading taxes itself will go down," he said.
Taken together with other reforms particularly the proposed GST and the restrictions on cash spending subjected to PAN declaration, it is going to "bring down the levels of corruption in society", he said.
Stating that the government is ready for a debate on the demonetisation issue in Parliament, he urged the Congress and other opposition parties to "rise above slogans and look at the positive advantages that this changes system in the long run is going to bring to the economy as a whole".
"Therefore, from national perspective, I would appeal to the opposition to join this campaign rather than create obstruction and fail to understand what the real purpose and the import of this campaign really is," he said.
