Anglo American Plc led a slump in mining stocks to the lowest in more than a decade as market turmoil in China, the biggest consumer of metals, ignites a vicious spiral of tumbling equities and collapsing commodity prices around the world.
The 80-member Bloomberg World Mining Index sank as much as 4.1 percent on Thursday, with Anglo sliding 12 percent at one point to a record low and Glencore Plc down as much as 7.9 percent in London trading.
The Bloomberg Commodity Index, a gauge of returns on raw materials, dropped to its lowest level since 1999 as industrial metals and oil declined.
