The rupee pared its initial gains to close marginally down by 1 paisa at 74.88 against the US dollar on Tuesday due to worries that the alarming surge in COVID-19 cases could derail the economic recovery in the country.

At the interbank forex market, the domestic unit opened at 74.65 against the US dollar, but lost ground to close at 74.88 against the US dollar. During the session, the local unit witnessed an intra-day high of 74.64 and a low of 74.98 against the greenback.

Meanwhile, the dollar index, which gauges the greenback's strength against a basket of six currencies, fell 0.04 per cent to 91.03.
