The rupee finished at an all time low of 74.39 on Tuesday against the US dollar on account of high crude oil prices, strengthening of the dollar and unabated foreign fund outflows.
Falling for the sixth straight sessions, it finally closed at 74.39 against the US dollar, down by 33 paise.
At the Interbank Foreign Exchange (Forex), the rupee made a cautious recovery of 18 paise to 73.88 against the US dollar in early trade on fresh selling of the American currency by banks and exporters.
However, the domestic currency failed to sustain the momentum after Brent crude breached the USD 84 per-barrel-mark again and the US dollar strengthened overseas.
On Monday, the domestic unit plummeted by 30 paise to close at 74.06.
Traders said unabated foreign fund outflows weighed on the rupee.
Foreign institutional investors (FIIs) sold shares worth a net of Rs 1,805 crore Monday, provisional data showed.
Investors remained concerned over sustained foreign capital outflows and rise in crude oil price to USD 84.48.
Forex dealers said besides strong demand for the American currency from importers, concerns over rising fiscal deficit and capital outflows weighed on the domestic currency.
"The balance of payments (BoP) turning negative has led to a sharp depreciation in rupee in the past two months. With steep depreciation over the past two months, rupee is now the worst performing currency against the USD in Asia so far this year, down 13.4 per cent," global brokerage firm Nomura said in a research note.
Traders said rising crude oil prices and higher US bonds yields resulted in weak Indian currency.
"Interest rates are headed higher in the US. The US 10 year bond yields surged to 3.26 per cent. Fears that global investors will withdraw their funds from global markets and park in US treasuries is affecting the global markets. Crude oil prices also rose 1 per cent to USD 84.7," said V K Sharma, Head PCG & Capital Markets Strategy, HDFC Securities.
Nomura further noted that policy responses to the depreciating currency have been muted thus far and with limited policy response, the concerns on the rupee have risen significantly.
"We believe a fall in oil prices will only possibly help stabilise rupee," it added.
Meanwhile, the BSE Sensex erased all its early gains to end lower by 175 points in see-saw trade Tuesday, posting its fourth fall in five sessions.
The 30-share Sensex opened higher at 34,651.82 points but slipped into the negative zone to hit a low of 34,233.50 before concluding at 34,299.47, recording a fall of 174.91 points, or 0.51 per cent.
Similarly, the NSE Nifty after shuttling between 10,397.60 and 10,279.35 points, ended 47 points, or 0.45 per cent, lower at 10,301.05.
