The RBI Friday tweaked norms for exchange of mutilated currency notes following introduction of Rs 2,000, Rs 200 and other lower denomination currencies. Post demonetisation in November 2016, the Reserve Bank has introduced Rs 200 and Rs 2,000 notes. Besides, it came out with smaller notes of Rs 10, Rs 20, Rs 50, Rs 100 and Rs 500. Public can exchange banks mutilated or defective notes at RBI offices and designated bank branches across the country for either full or half value depending upon the condition of the currency. While making amendments to the Reserve Bank of India (Note Refund) Rules, 2009, the central bank said it has been done to enable the public to exchange mutilated notes in Mahatma Gandhi (New) series, which are smaller in size compared to the earlier series. These rules have come into force with immediate effect. We further inform that there is a change in the minimum area of the single largest undivided piece of the note required for payment of full value for notes of rupees fifty and above denominations, the RBI said.
