The rupee on Monday plunged by six paise at 48.14 against the US currency in early trade on increased dollar demand from importers and a strong American unit in the overseas market.
At the Interbank Foreign Exchange (forex) market, the domestic currency lost six paise to quote at 48.14 over previous close of 48.08/09.
Forex dealers said heavy dollar demand from importers and strengthening dollar against major currencies mainly led to the fall in rupee.
Meanwhile, the BSE benchmark Sensex is likely to open flat. The Indian benchmark Sensex ended higher by 256.36 or 1.80 per cent on Friday.
