While the world was watching the outcome of the US Presidential election, a momentous policy change was announced in India. On November 8th, the Modi government announced that all 500 and 1,000 rupee notes would no longer be legal tender. Existing notes must be exchanged at a bank for new rupee notes and this must be done by December 31, 2016. These notes account for over 85% of total bills in circulation in India. The process of over a billion people changing this magnitude of old money into new money is a massive undertaking. We were on the ground in India a few days after the demonetisation was announced. We witnessed long lines at banks as people clambered to exchange notes.
