The rupee saw a steep fall of Rs 1.05 in the last three days and it continued the southward journey following the bullish phase in crude oil prices.
Rupee fell to a year's low at 41.76 per dollar as record high oil prices pushed up dollar demand from refiners and weak stock markets doused hopes for foreign inflows.
Later, Rupee ended at 41.76/77 per dollar, off an intraday low of 41.80, the weakest since April 20, 2007, and high at 41.53 against the US dollar. The rupee had closed at 41.36/37 on Wednesday.
Reserve Bank of India today fixed the reference rate for US Dollar at Rs 41.79, up 59 paise from yesterday's rate of Rs 41.20 per USD.
The six-month premium was quoted at 1.56/52 (1.80/82) per cent and annualised premium closed at 1,37/39 (1.53/55) per cent.
The local currency ended the day at 64.07/09 (63.67/69) against the Euro, 81.58/60 (80.69/71)per unit against the Pound Sterling and 40.06/08 (39.20/22) per hundred units against the Japanese Yen, dealers said.
