The Indian rupee depreciated by 13 paise against the dollar in early trade today, following gains in the US currency against its rivals.
Capital outflows by foreign funds from equities too put pressure on the rupee.
At the Interbank Foreign Exchange (Forex) market, the rupee fell by 13 paise to 45.56 a dollar.
The rupee closed higher by 18 paise at 45.43/44 a dollar in the previous session on Friday.
Forex dealers said besides strong dollar overseas, some demand from importers for the US currency also weighed on the rupee sentiment.
Meanwhile, the Bombay Stock Exchange index Sensex fell by 77.67 points, or 0.45 per cent at 17,088.95 points in the opening trade today.
