On the evening of 8 November 2016, Narendra Modi announced that the existing ₹500 and ₹1,000 banknotes would cease to be legal tender at midnight. People could deposit the withdrawn notes, subject to the prescribed rules, while replacement currency entered circulation. A decision presented as a campaign against black money immediately became a practical problem of exchanging cash. [1]
The scale was exceptional. The two denominations represented 86% of currency in circulation by value, according to the subsequent study by economists Gabriel Chodorow-Reich, Gita Gopinath, Prachi Mishra and Abhinav Narayanan. New notes would take months to replace the withdrawn stock. [3]
The money that came back
The government’s announcement linked demonetisation to corruption, counterfeit currency and terrorist financing. It also announced new ₹500 and ₹2,000 notes and a deposit window running to 30 December. These were the policy’s stated purposes and initial arrangements; they were not measurements of what it accomplished. [1]
The eventual reconciliation produced a striking number. In a January 2019 parliamentary reply, the finance ministry put the value of withdrawn notes outstanding on 8 November 2016 at ₹15,417.93 billion, and the value returned at ₹15,310.73 billion. Approximately 99.3% had come back. [2]
That left little of the withdrawn stock outside the return process. It did not establish that every deposit was legitimate, or that all illicit wealth had been held in cash. Determining tax evasion required examining deposits and their owners; counting returned notes could not answer those questions by itself.
The cost of a cash shortage
The economists’ study compared districts experiencing different degrees of cash replacement. It combined employment surveys, satellite measures of night-time light, payment data and banking records. More severely affected districts experienced weaker activity and faster adoption of alternative payment methods. [3]
Their estimates implied employment and nightlights-based output were at least two percentage points below their counterfactual paths in the final quarter of 2016. The effects dissipated over the following months. This was evidence about the cash shortage, with specified methods and a limited period, rather than a calculation of every long-term cost or benefit. [3]
The Supreme Court addressed a different question in January 2023. A four-judge majority upheld the decision; Justice B.V. Nagarathna dissented over the legal route used for a government-initiated withdrawal. The majority expressly declined to determine whether demonetisation had achieved its objectives or produced the claimed benefits. [4]
The ruling settled the challenge before that bench without resolving the economic argument. The enduring records remain distinct: an implemented currency withdrawal, an almost complete return of the affected notes, and measurable disruption while cash was being replaced. [2] [3] [4]
