The rupee erased its initial gains to end 10 paise weaker at 59.04 against the dollar due to month-end dollar buying by importers and poor performance of the domestic equity market.
The domestic unit had ended stronger on Wednesday at 58.94 per dollar.
On Thursday, the unit nudged up in the opening trade at 58.92 at the Interbank Foreign Exchange (Forex) market. It strengthened to 58.79 on dollar sales by foreign investors.
However, the rupee broke the rising momentum as the dollar demand from banks on behalf of oil importers and capital outflows from the domestic equity market weighed on the rupee.

This led the rupee to decline to 59.07 towards the end of the trading session. Intra-day, it moved 28 paise in a range of 58.79 and 59.07 per dollar.
Market investors will keenly watch for the monetary policy by the RBI next week. RBI Governor Raghuram Rajan has hinted at a hawkish policy stance by saying that it will be targeted at inflation.
