Platinum holdings slumped 16% to a three-week low. Prices fell 5.4% in New York last week, the most since December 2011.
Investors increased their net-short position in copper to 29,018 contracts, from 18,722 a week earlier, CFTC data show. Prices fell for a sixth week, the longest slump in a year. Stockpiles monitored by the London Metal Exchange have more than doubled this year.
A measure of net-long positions across 11 agricultural products fell 7.9% to 296,081 futures and options, as soybean and cattle holdings dropped.

Bullish corn bets declined 9.8% to 74,405, the lowest since May 21.
