Market benchmark BSE Sensex tanked nearly 537 points to end at over two-month low of 36,305.02 and the Nifty crashed below the 11,000-mark on Monday, extending their slide for the fifth straight session after heavy losses in banking and auto stocks.

The 30-share Sensex hit a low of 36,216.95 before settling at 36,305.02, down by 536.58 points or 1.46% — the biggest single-session fall since February 6 when it had lost 561.22 points.

This is the weakest closing since July 11 when it settled at 36,265.93. The index had lost 1,249.04 points in the previous four sessions.

The broader NSE Nifty cracked below the 11,000 level by dropping 168.20 points, or 1.51 % to end at 10,974.90 due to foreign fund outflows amid prospects of a 25 basis point hike in the interest rate by the U.S. Federal Reserve this week.

Yes Bank fell by another 0.35%, taking its total losses to more than 29% after the RBI curtailed the term of its founding CEO Rana Kapoor.

Bucking the trend, IT stocks TCS and Infosys rose by 4.5% and 1.5%. Coal India rose by 2.1% while Reliance gained 1.27%.

Sentiments remained distinctly weak in sync with declining global markets as the intensifying dispute between the world’s two biggest economies has spooked financial markets worried about the fallout on global growth, brokers said.
