Mumbai, May 5: The Indian rupee strengthened by 13 paise to trade at 60.03 against the dollar Monday, extending its rising streak for the fourth straight day, at the Interbank Foreign Exchange market on sustained selling of the US currency by exporters.

The local currency had appreciated by 15 paise to close at three-week high of 60.16 per dollar on Friday, following sustained selling of the US currency by exporters amid capital inflows.

Dealers said besides persistent dollar selling by exporters, gains in other currencies against the American currency overseas supported the rupee but a lower opening in the domestic equity market, capped the gains.

Meanwhile, the BSE benchmark index Sensex fell by 16.00 points, or 0.07 per cent, to 22,387.89 in early trade.
