The demerger is effective April 1, 2017, Cox & Kings said in a statement.
Cox & Kings Group CEO Peter Kerkar said: "Strong macro drivers coupled with a strategic brand presence will enable CKFSL to flourish".
There are abundant, large-sized avenues for natural product diversification and the timing of this demerger is most opportune, he added.
With a view to enable the forex business to capitalise on growth opportunities in an independent manner, it has been decided to demerge it into a separate company, Cox & Kings said.
Shares of Cox & Kings today closed at Rs 217.50 per scrip on BSE, up 2.50 per cent from its previous close.
