The rupee was trading weak at 63.96 against the US currency on dollar demand from importers.

The rupee’s weakness against the dollar was in line with the global trend where the greenback rose against other currencies overseas on better-than-expected US growth data. However, a firm domestic equity market capped the rupee's losses.

The domestic unit opened weak by 3 paise at 63.93 at the Interbank Foreign Exchange market today. It hovered in a range of 64 and 63.87 before quoting at 63.96, down 6 paise at 11.10 am local time.

Yesterday, the rupee had closed at 63.90 against the American currency by gaining 11 paise on bouts of dollar unwinding from exporters and corporates.

Meanwhile, the benchmark BSE Sensex was trading higher by 138.26 points or 0.44 per cent at 31,857.86.
