New Delhi: Expressing concern over the circulation of fake currency notes, Reserve Bank of India Governor Urjit Patel on Tuesday said the apex bank will launch new Rs 500 and Rs 2,000 currency notes from November 10.

"RBI will launch new currency notes from November 10," Economic Affairs Secretary Shaktikanta Das said while unveiling the new notes.

Both Patel and Das were briefing media after Prime Minister Narendra Modi in a sudden address to the nation on Tuesday, announced that Rs 500 and Rs 1,000 denomination notes are being withdrawn from midnight. He said that such notes will become "mere paper".

"Banks will keep record of people who will come to exchange cash," Das added.
