The rupee today lost four paise to 55.58 against the dollar in early trade as the American currency gained strength against euro and other Asian currencies.
Forex dealers said besides dollar's gains in the overseas markets, a weak opening in the stock market following capital ouflows, also put pressure on the local unit.
The rupee had gained a whopping 54 paise to end at 55.54 against the dollar on Friday's trade on persistent dollar- selling by exporters amid RBI hinting at opening a separate dollar window for oil firms.
Meanwhile, the BSE benchmark Sensex fell by 161.62 points, or 1.01%, at 15,803.54 in early trade today.
