The bourse has also decided to continue with the transaction fee it is currently levying on trading members for interest rate futures (IRF) for two months.
The National Stock Exchange (NSE), in March, this year, lowered transaction charges for trading on its currency derivatives platform. It had, among others, given a discount of up to 59 per cent on such levies.
These concessions, which were valid up to July 31, have now been extended for a further period of two months.
In order to improve the liquidity in the currency futures segment, NSE in March 2015 had decided to provide a concession in the transaction charges including discounts.
