The rupee depreciated by 4 paise against the dollar in early trade today following the US currency's gains overseas.
At the Interbank Foreign Exchange (Forex) market, the rupee fell by 4 paise to 46.32 a dollar. The rupee had closed lower by 8 paise at 46.32/33 a dollar in the previous session.
Forex dealers said besides strong dollar overseas, month-end demand from importers for the US currency also weighed on the rupee sentiment.
Meanwhile, the Bombay Stock Exchange index Sensex rose by over 73 points, or 0.45 per cent at 16,329.33 points in the opening trade today.
