Falling for the third session in a row, the BSE benchmark Sensex today closed down by 320 points.
The 30-share BSE index Sensex slipped below the psychologically important 17,000 levels amid heavy selling by foreign funds due to fresh concerns over the Mauritius tax treaty review and a weak rupee.
The 30-share Sensex, which had lost 168 points in last two trading sessions, plunged further by 320.11 points or 1.87 per cent to 16,831.08, its lowest level since January 30.
Similarly, the 50-share NSE Nifty dropped by 101.55 points or 1.96 per cent to 5,086.85 led by a steep fall in the stocks of capital goods and banking sectors.
Rupee fall
Brokers said the weakening of rupee to a fresh four-month low spur concerns that the Government might find it hard to cool inflation and curb the fiscal deficit.
The rupee slid as low as 53.84 per dollar, the weakest since December 15, lifting the cost of imported oil, fuelling inflation and reduce scope to cut interest rates.
US jobs data
A weak trend in the Asian region and lower opening in Europe ahead of US jobless data and elections in France, Greece, Italy and Germany this week-end further fuelled the selling pressure.
The domestic stock market received another jerk as Reliance Industries dropped by 1.68 per cent to Rs 726.45 following reports that the Oil Ministry has hiked the penalty for falling natural gas output from KG-D6 fields.
Euro Zone debt crisis
Infosys dropped by 1.74 per cent to Rs 2,441.15 on fears that the Euro Zone debt crisis might affect the revenue of software exporting companies. IT companies get more than 50 per cent of their revenues from the US and Europe.
The BSE Capital Goods sector index suffered the most by losing 3.74 per cent to 8,908.74 followed by the BSE Bankex that closed 3.17 per cent down at 11,284.03.
