"I don't approve of personal comments against anyone, let alone the RBI Governor," the minister said when asked about the continuing attack on Rajan in past few months and whether there was an effort on part of the government to ring-fence the Governor.
The Reserve Bank, Jaitley said, is an important institution which makes its own judgement.
"One can agree or disagree with their judgment, but that's a debate on issues. But I don't think we should allow a public discourse where instead of debate on issues we concentrate on debate on persons," he told NDTV.
Swamy also accused Rajan of sending confidential and sensitive financial information around the world.

Jaitley said RBI and the government are in continuous dialogue and that relationship will continue.
"And I hope from the later part of this year, the Monetary Policy Committee will get into action and therefore, both the bank and the government nominees will have to sit together and decide monetary policy," he said.
the rupee will crash and economy will face crisis if Rajan is removed as RBI Governor, Jaitley said there was no need for him to comment.
"I think in democracy debate of every kind takes place. Now people make comment one way, somebody else makes the other way. I read those comments, its not necessary for me to express views on those comments," he said.
On a question that should RBI Governor remain conservative and publicly shy, Jaitley said it all depends upon individuals.
"It depends on persons. Even among ministers you will have people who express themselves freely...You can always have personalities which keep to themselves and just read statements.
As an outspoken RBI Governor, Rajan has expressed his views on host of issues, including intolerance and has even described India as 'one-eyed king' in the land of blind in reference to the country's high economic growth.
