The rupee appreciated 12 paise to 77.46 against the US dollar in opening trade on Monday, supported by a fall in the dollar index and positive domestic equities.
At the interbank foreign exchange, the rupee opened at 77.53 against the American dollar, then gained further ground to quote 77.46, registering a rise of 12 paise from the last close.
On Friday, the rupee had settled at 77.58 against the US dollar. Global oil benchmark Brent crude futures surged 0.54 per cent to USD 120.08 per barrel.
The dollar index, which gauges the greenback's strength against a basket of six currencies, was trading 0.11 per cent lower at 101.55. According to Sriram Iyer, Senior Research Analyst at Reliance Securities, the Indian rupee could trade in a narrow range against the dollar this Monday, as a fall in the dollar index could offset losses from strong crude oil prices.
Asian currencies were stronger and could aid sentiments while emerging market peers were weak, Iyer said. On the domestic equity market front, the 30-share Sensex was trading 885.17 points or 1.61 per cent higher at 55,769.83, while the broader NSE Nifty advanced 261.80 points or 1.6 per cent to 16,614.25.
