Copper futures fell by more than 6% on Sept. 22, 2011. Rio Tinto's shares were down close to 11%. In 2011 shares of BHP, Rio Tinto and Xstrata have dropped by 30-40% from the peak reached on July 7. This is much faster than the fall in metals prices. The Dow Jones-UBS Industrial Metals Index declined by 19% in that period. The decline in mining shares suggest medium term metals prices will drop to the recession levels in the last quarter of 2008 and the first quarter of 2009, according to RBC Capital Markets. This view is not reflected in commodities markets. Iron ore prices are double now compared to prices during the 2008-2009 recession, and copper prices at $3.48 are much higher than the $2.02 average price during the 2008-2009 recession. Goldman Sachs estimates that BRIC's growth would have to decline sharply for this to happen.
