The rupee rose 12 paise to end at 66.59 against the dollar on Friday at the Forex market on increased selling of the US currency by exporters and banks.

The domestic unit moved between 66.72 and 66.55 in intra-day deals.

Forex dealers said that besides selling of the American currency by exporters and banks, weakness of the dollar against other currencies overseas also supported the rupee.

Yesterday, the rupee closed flat at 66.71 against the dollar as cautious traders avoided taking any position ahead of the exit polls outcome and concerns over an impending Fed rate hike next week.
