The Indian rupee on Tuesday gave up all its intra-day gains to close 6 paise lower at 75.61 against the US dollar in line with weaker sentiment in financial markets triggered by steeply rising coronavirus cases in the country.
Besides, robust US dollar against its key rivals also had an impact on the domestic unit.
The dollar index, which gauges the greenback's strength against a basket of six currencies, rose 0.42 per cent to 97.02.
The rupee opened at 75.53 against the US dollar, but pared the gains to settle at 75.61 against the US dollar, down 6 paise over its previous close.

Likewise, the NSE Nifty ended 120.80 points or 1.19 per cent down at 10,046.65 as an uncertainty about economic revival amid mounting COVID cases in the country hung heavy on investor minds.
Foreign institutional investors were net buyers in the capital market as they bought shares worth Rs 490.81 crore on Tuesday, according to provisional exchange data.
Brent crude futures, the global oil benchmark, fell 1.27 per cent to USD 40.28 per barrel.
Forex traders said rupee surrendered its intra-day gains due to dollar buying by banks and oil importers.
"Traders refrained from placing aggressive bets in favour of the rupee due to concern over India's macroeconomic fundamentals and caution continue after the Reserve Bank of India's dollar-buying interventions in the spot market around 75.40 per dollar of late," said Jateen Trivedi, Senior Research Analyst (Commodity & Currency) at LKP Securities.
According to Devarsh Vakil, Deputy Head of Retail Research, HDFC Securities, traders are weighing the global stock rally amid still challenging economic conditions.
"The strong dollar inflows supporting rupee while rise in COVID-19 cases after Unlock-1 and weaker economic data weighed down on rupee," Vakil said.

In India, the death toll due to COVID-19 rose to 7,466 and the number of infections rose to 2,66,598, according to the health ministry.
