Unfazed by criticism of the demonetisation move, Finance Minister Arun Jaitley on Friday said replacing 86 per cent of the currency in circulation with new bank notes could not have been executed in a better way than currently being done. Ten days after the Government withdrew Rs 1,000 and Rs 500 rupee notes, he said the move will help banks lend at a cheaper rate to businesses, trade, agriculture and infrastructure while getting rid of the shadow economy.
