Over 500 kilograms of gold has been mobilised under the gold monetisation scheme. Economic Affairs Secretary Shaktikanta Das gave the information through a tweet yesterday adding that the scheme is picking up. He said the government is committed to making both gold bond and monetisation scheme successful. Under the monetisation scheme, launched on November 5th last years, banks were authorised to collect gold for up to 15 years to auction them off or lend to jewellers from time to time. Depositors will earn up to 2.50 per cent interest per annum.
