Woodcutter is right about the contract size: I was thinking in terms of pounds--the COMEX unit size, but he's wrong about OI: LME updates "Market Open Interest" daily at http://www.lme.co.uk/dataprices_reports.asp. Still, the amount of copper in question is negligible. So the media have identified the possible holder of a 4-8000 contract short position; since there are holders of over 340,000 long contracts, focusing great mental energy on discerning motives of this one short holder is a waste. Big copper players have dismissed this news. It's better to focus on this weird move up in this metal: copper initially moved up on unprecedented Chinese buying in Fall 2003 which buying happened at the same time as a disastrous landlide at the world's largest copper mine, Freeport McMoran's Grassberg mine in Indonesia. Since these events, Chinese imports have dropped sharply, and Grassberg is operating at nearly 100%. I took about 10 cents out of copper on the short side in May before I fortunately stopped trading it. I still cannot figure out this move up. Until I do, I won't trade it again from either the long or short side.
The fact is that there is 55,000tonnes of lme warranted stock, it is alleged that SRB have to deliver 200,000tonnes to the market on the 21st Dec of this year to satisfy their short position, and 200 doesn't go into 55 very well so they either have to buy the outright, borrow the position to a later date, or warrant material from their alleged stockpile of 1.2m tonnes which isn't straightforward. But if you think this is a whole lot of nonsense then sell copper....
your link didn't work but the LME publish gross client and exchange open interest which often means positions are double counted ... fyi;
