"The demonetisation exercise has resulted in net loss of seigniorage to the RBI," SBI's research report Ecowrap said.
"In the current case, there is a seigniorage loss, as the face value of Rs 15.28 trillion of Rs 17.1 trillion has been printed," it said.
The report further said that "the cost of printing notes and coins has increased during this year".
In its Annual Report for 2016-17, RBI has said that post-demonetisation it has spent Rs 7,965 crore on printing new Rs 500 and Rs 2,000 and other denomination notes, more than double the Rs 3,421 crore spent in the previous year.
The banned notes formed 86 per cent of the currency in circulation at that time. Holders of old notes were given a 50-day window to deposit them in banks.
The estimated value of Specified Bank Notes (SBNs) received as on June 30, 2017 is Rs 15.28 trillion (Rs 15.28 lakh crore) out of Rs 15.44 trillion demonetised currency. The net transfer of profits to the Union Government as a result have fallen drastically during this year by 53.5 per cent.
The report further said that the number of suspicious transaction reports by Banks/FIs/Intermediaries also increased by 345 per cent and this in turn "could possibly lead to increase in future tax revenues".
"This coupled with implementation of GST will help in better fiscal realisation at a future date," the report added.
