In late 2016, the Indian Prime Minister, Narendra Modi, came on TV at 8 pm to announce that most currency bills would no longer be legal tender after midnight. An individual was allowed to convert only about $30 per visit to the bank. This led to massive crowds (not lineups, because Indians don’t follow the lineup system) at the banks, suffering, chaos, and deaths— there were no exceptions for the sick, older people, and pregnant women.
Eventually, more than 100% of the demonetized cash returned to the banks, although I know no one who didn’t forget to convert some of his misplaced currency bills. What happened? Demonetization ended up laundering massive amounts of counterfeit currency. But thinking through the consequences of their utopian—rather puerile—policies isn’t within the competencies of the Indian bureaucrats. Worse, to patch up, they kept issuing contradictory policies that even school students should not make. This led to a constant cycle of paranoia, rumors, and confusion.
