Why RBI decided to scrap Rs 2000 notes?

The Rs 2,000 denomination banknote was introduced in November 2016, primarily to meet the currency requirement of the economy in an expeditious manner after the withdrawal of the legal tender status of all Rs 500 and Rs 1,000 bank notes that were in circulation at that time.
The objective of introducing Rs 2,000 banknotes was met once banknotes in other denominations became available in adequate quantities. Therefore, the printing of Rs 2,000 banknotes was stopped in 2018-19, RBI said.
About 89 percent of the Rs 2,000 denomination banknotes were issued prior to March 2017 and are at the end of their estimated life span of 4-5 years. The total value of these banknotes in circulation has declined from Rs 6.73 lakh crore at its peak of March 31, 2018 (37.3 percent of notes in circulation) to Rs 3.62 lakh crore constituting only 10.8 percent of notes in circulation on March 31, 2023, the apex bank added.
The Reserve Bank of India (RBI) on Friday said it has decided to withdraw the Rs 2,000 denomination bank notes from circulation. However, the Rs 2,000 denomination bank notes will continue to be legal tender.
