Mumbai - The rupee lost 21 paise to Rs 63.50 against the US dollar in early trade Monday at the Interbank Foreign Exchange due to rise in the greenback's value against other currencies overseas.

Dealers attributed the fall in rupee to dollar's gains against the euro which fell to a nine-year low; but a higher opening in the domestic stock market limited the fall of the domestic currency.

The Indian rupee had ended 6 paise higher at 63.29 against the greenback on Friday, helped by selling of dollars by banks and exporters amid hopes of more foreign capital inflows into the equity market.

Meanwhile, The benchmark BSE Sensex regained the 28,000-mark by rising 122.45 points, or 0.44 percent, to 28,010.35 in early trade today. PTI
