Forex dealers said besides dollar's gains against euro and yen in the overseas markets following a rise in the US data, a weak opening in the stock market also put pressure on the domestic currency.
The rupee had strengthened by 15 paise to close at 55.27 against the US dollar yesterday on sustained capital inflows.
Meanwhile, the BSE benchmark Sensex fell by 33.18 points, or 0.19 per cent, at 17,527.69.
