Finance Secretary T V Somanathan spoke to Shrimi Choudhary in New Delhi on why the step was taken. Edited excerpts:
It has outlived its purpose, especially with the growth of digital transactions at payment systems. It was introduced for a quick circulation after the [2016] demonetisation, and it has served its purpose. Now there is no need to have a high-denomination note keeping in view the spread of electronic transactions.
