"We have got clear directions from the EC not to make available indelible ink to banks," CEO Kunal told reporters here.
Kunal said the EC has decided to keep a close watch on supply of the ink in Goa, where Assembly election schedule is yet to be announced.
The IAS officer said life of the ink, supplied by a Mysore -based firm, is restricted to two-three weeks only.
"But to avoid any confusion during elections, we will monitor the supply and usage of ink once the poll code comes into force."
The central bank took the measure to stop repeat money exchangers thronging banks with invalid currency notes and reduce the rush of customers.
The EC gets stock of indelible ink at the time of elections.
