India's Bonfire of the Bank Notes

Why did India's prime minister ban the use of the country's most widely used bank notes? On 8 November, the Indian Prime Minister Narendra Modi made a stunning announcement. As of midnight that day, all 500 and 1000 rupee notes would no longer be legal tender. The announcement came as a shock not only to the Indian public, but also to businesses, banks and some of Mr Modi's closest advisors. Large queues formed at banks across the country as people tried to exchange their old notes for new ones and businesses came to a grinding halt. Agriculture was one of the sectors that was hardest hit. It was sowing season for India's farmers, many of whom had no means to buy the seeds, so reliant are they on cash transactions.So what was Modi trying to achieve through this shock and awe tactic? Is this a stroke of economic genius or a highly damaging political move? And did the move have the desired effect? David Aaronovitch speaks to a panel of experts to find out.CONTRIBUTORS: Nilanjan Mukhopadhyay, author of a biography about Narendra Modi, Narendra Modi: The Man, The TimesIla Patnaik, former economic advisor to the Modi government and a professor at the National Institute of Public Finance and PolicyDouglas Busvine, Reuters bureau chief in New DelhiJustin Rowlatt, BBC South Asia CorrespondentProducer: Phil Kemp Research: Serena Tarling and Kirsteen Knight Editor: Innes Bowen.
