The rupee ended 15 paise weaker at 61.94 against the dollar on a weaker euro and dollar demand from oil importing companies. The domestic unit had closed at 61.79 on Friday.
The unit opened at 61.74 on Monday aided by foreign capital flows into the domestic equity markets. It strengthened to 61.65 per dollar at the Interbank Foreign Exchange market.
However, the rupee was pulled down after the Euro depreciated to a near two-year low as investors bet the European Central Bank will ease monetary policy more aggressively to ward off deflation.
In addition, demand for the American currency from state-run banks on behalf of oil importers were also a drag on the rupee, which fell to 61.96 during the closing hours.
Investors will further watch out for key economic data due this week. The government will issue gross domestic product (GDP) data for the September quarter and fiscal deficit data for October on 28 November.
