Sometime ago, Baba Ramdev had suggested taking Rs 500 and Rs 1,000 notes out of circulation as a measure to curb black money. Possible? No, Reserve Bank Deputy Governor K C Chakrabarty told someone who asked the question at an event. Withdrawing these notes and introducing an equal amount of money in lower denominations was beyond the current capacity of the mint, he explained. So, doing this would stall many day-to-day transactions. The question is whether the yoga guru-turned activist will understand this simple truth.
