The Indian rupee on Monday slid 20 paise to close at 75.01 to the US dollar, weighed down by lackluster equities and concerns over a continuous surge in COVID-19 cases in the country. Starting off the session on a weak note, the domestic unit swung between a high of 74.88 and a low of 75.03.
It finally ended at 75.01, registering a loss of 20 paise against the greenback.
The dollar index, which gauges the greenback's strength against a basket of six currencies, rose 0.11 per cent to 93.45.
Forex traders attributed the rupee fall to a host of reasons like stronger dollar, muted domestic equities and rising COVID-19 cases dragged the local unit down.
On the domestic equity market front, the BSE Sensex plunged 667.29 points or 1.77 per cent to end at 36,939.60; while the NSE Nifty slumped 181.85 points or 1.64 per cent to settle at 10,891.60.
