At the Interbank Foreign Exchange (Forex) market, the local currency resumed lower at 60.23 a dollar from previous close of 60.13. It then declined further to one-week lows of 60.3850 on initial dollar demand from importers, mainly oil refiners.
Lacklustre trade on the local equity markets also weighed on the rupee. The Indian benchmark S&P BSE Sensex today closed down by 55.16 points, or 0.22 per cent. FIIs had infused Rs 284.61 crore yesterday, as per provisional data.
Anindya Banerjee, currency analyst, Kotak Securities, said: "The Indian rupee weakened at the open due to uptick in global petroleum prices. However, hedging demand from ITes sector, pushed it back up towards 60.17/18 levels on spot. PSU bids were absent in today's session and there was little inter-market effect from a largely ranged equity market."
The dollar index was up by 0.03 per cent against six major global rivals.
Militants launched a dawn raid today on a key Iraqi oil refinery they have been trying to take for days but were repelled by security forces. US benchmark West Texas Intermediate rose 17 cents to USD 106.20 a barrel while Brent crude eased 65 cents to USD 113.81 in afternoon trade.
