Reports have come in from various parts of the country about a shortage of currency notes. In Bihar, Karnataka, Gujarat and Telangana, in particular, there are reports of ATMs running dry, although the phenomenon is not limited to those areas. In response to these concerns, the government and the Reserve Bank of India (RBI) have issued statements intended to reassure the public. The finance minister has said that there is enough currency in circulation. The central bank has said that there is “sufficient cash in the RBI vaults and currency chests”. Both went on to add that there was unexpected demand for currency, leading to localised and temporary shortages. But it is clear that, if there are indeed shortages, then there is, by definition, not “enough” currency in circulation. The government and the central bank have likely miscalculated the demand for currency and overestimated the velocity of money — the rate at which currency changes hands. The increase in the rate of ATM withdrawals — according to the State Bank of India, such withdrawals increased by 12.2 per cent in the second half of 2017-18, 4 percentage points over the normal rate of increase — has clearly been known for some time. It is thus unclear why the authorities did not respond in time to the developing situation. Why should there be a cash crunch before the RBI steps up its printing of notes?
