The rupee today lost 33 paise to 54.14 against the US dollar in early trade. This happened due to appreciation of the American currency against the euro and other rivals overseas and a weak opening in the domestic equity market.Increased demand for the dollar from banks and importers also put pressure on the rupee. Dealers attributed the rupee's fall to dollar gains against the euro overseas and a lower opening in the stock market.The rupee had closed 11 paise lower at 53.81 a dollar on Friday.
