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 per cent, at 15,803.54 in early trade today.
