Stocks in India continued to slide on Monday registering the largest monthly decline in 16 years, after the Left allies of the United Progressive Alliance coalition government threatened to withdraw their support for Prime Minister Manmohan Sigh if the Congress singed a nuclear agreement with the United States. Also weighing on investor sentiment in the Far East were rising inflation concerns following record high crude oil prices that touched $143 a barrel in pre-market trading on the New York Mercantile Exchange."It is a complete breakdown of confidence. The nervousness is quite high," said Deven Choksey, CEO of the brokerage KR Choksey. "Panic is leading to further panic. We need some comforting words that suggest the fundamentals are still intact and inflation is being addressed to arrest this free fall." The Bombay Stock Exchange's Sensex Index dropped 340.62 points, or 2.47%, to 13,461.60. The Sensex is now down 34% year-to-date, its worst six-month showing on record.
