In tandem with weaker equities, the rupee on Friday closed 10 paise lower at 60.18 against the US dollar driven by higher oil-related demand for the American currency, extending its string of weekly losses to four.
The rupee resumed lower at 60.22 per dollar as against the last closing level of 60.08 at the Interbank Foreign Exchange (Forex) Market. It hovered in a range of 60.14 per dollar and 60.34 per dollar during the day, before ending at 60.18 per dollar, showing a loss of 10 paise or 0.17%.
The local unit has lost 41 paise this week. It had lost 60 paise, 6 paise and 59 paise in the three preceding weeks.
Banks and importers today preferred to increase their dollar position due to rise in crude oil due to ongoing violence in Iraq, say forex dealers.
The dollar index, a gauge of six major global rivals, was up by 0.11%.
"Rupee was seen trading weak during the session taking cues from the soaring global crude prices as crisis in Iraq continued. Domestic currency was seen leading the losses along with Indonesia's Rupiah reflecting the threat that increased crude poses to both countries' current account balances and inflation rates," said Abhishek Goenka, Founder & CEO, India Forex Advisors.
In the international market, crude oil prices retained support near a nine-month peak as dealers track the unfolding conflict in Iraq fearing it could cause supply disruption.
Brent crude for August eased 15 cents to $114.91 in mid-morning trade, after rallying to $115.06 in London, its highest since early September.
In London, the dollar was under pressure in the early trade on Friday, heading for its biggest weekly loss in over two months against a basket of currencies following the Federal Reserve's surprisingly dovish policy outlook.
Meanwhile, the Indian benchmark Sensex moved down by 96.29 points, of 0.38%, to end at 25,105.51.
