There are two objectives of demonetisation – ridding the system of counterfeit currency and destroying cash hoards. Both of these goals were cited by the government while carrying it out on Tuesday. Both can only be achieved by complete demonetisation of the existing series of currency notes. If this is not done, the cleaning-up process becomes excruciatingly slow. Old notes can only be withdrawn when they pass through the banking system.
The effectiveness of introducing new security features in notes is diluted by the fact that old notes remain in circulation as long as they do not pass through banks. Counterfeiters can simply copy the older notes, while the value of cash hoards remains intact. If it had to be done, it had to be done at one stroke.
