Besides, NSE has also announced a liquidity enhancement scheme for Exchange Traded Funds (ETFs) on its indices.
The third major player in this segment, MCX-SX had also tweaked its transaction charges for futures contracts traded on its currency derivatives platform earlier this month.
NSE's decision comes days ahead of BSE beginning to impose
charges for currency futures trade with effect from December 1, after exempting such trades from any transaction levy for about a year.
In equity options, NSE will give a flat concession of 40 per cent in the transaction charges levied on the incremental billable volume, or Premium value, above Rs 750 crores in a month for a period of 2 months beginning December 1.
Incidentally, BSE has clocked higher volumes than NSE in equity options segment in some recent days. In currency derivatives, NSE is the largest exchange, while BSE has now overtaken MCX-SX as the second largest player.
As per capital markets regulator Sebi's latest monthly bulletin, the turnover of currency derivatives at BSE increased by 22.6 per cent to Rs 1,41,170 crore in September this year from Rs 1,15,127 crore in the previous month.
This assumes significance as BSE began currency derivatives trade in November 2013 itself and it has overtaken MCX-SX as the second largest exchange in this segment with a market share of about 30 per cent currently.
The turnover at the fourth exchange USE in this segment also rose by 14.2 per cent to Rs 9,370 crore in September, over the previous month, making MCX-SX the only exchange to witness a decline.
While the turnover at BSE has almost doubled from Rs 72,000 crore in April this year, in case of MCX-SX it has marginally fallen from Rs 59,000 crore in the first month of 2014-15.
