Stocks Plummet in Germany, Hong Kong, India, Brazil in Rout

Stocks plunged in Germany, Hong Kong, India and Brazil, and U.S. index futures dropped on mounting speculation that the global economy is slowing and company defaults will rise.

Europe's Dow Jones Stoxx 600 Index fell the most since the Sept. 11 terrorist attacks and sank into a bear market, as Allianz SE and BNP Paribas SA slid. Hong Kong's Hang Seng Index had its biggest drop in six years after BNP Paribas said Bank of China Ltd. may write down overseas securities by $4.8 billion because of losses from U.S. subprime mortgages. Citigroup Inc. retreated in Frankfurt.
