The rupee depreciated by as much as 75 paise - or 1.06 per cent - against the US dollar hurt by soaring crude oil prices. After opening at 71.57 against the greenback, down 64 paise compared to the previous close, the rupee declined to 71.67 at the day's weakest point. Analysts say the sharp rise in crude oil prices following drone attacks on Saudi Aramco oil facilities hurt the rupee in the domestic forex market, stoking concerns about the twin deficits. At 2:41 pm, the rupee traded 52 paise - or 0.74 per cent - lower at 71.45 against the US currency.
