The rupee gained marginally tracking the positive equity markets on Friday. The domestic currency opened at 45.70 and closed at 45.68, against the previous close of 4.574. Exporters were seen selling dollars, which also helped the rupee, said a forex dealer with a private bank.

However, the lower IIP figures were a negative factor, he added. In the overseas market, the dollar gained against other currencies such as euro. This limited the extent of the rupee's gains. In the forward premia market, the one-year closed at 5.88 per cent (5.74 per cent).
