the article by john kemp seems clear that energy-related commodities will have position limits, but i'm not sure what gata is reading into this about precious metals:

In an e-mail to a GATA supporter today, U.S. Commodity Futures Trading Commission member Bart Chilton wrote that the financial regulation legislation pending in Congress, described in the report below, would require the commission to set position limits in all commodities of finite supply, including precious metals, which Chilton has advocated but which the commission still seems unprepared to do on its own.
