Silver struggles again after futures market raises margin requirements
Silver’s great bull market of 2011 may be facing its biggest test so far.
The metal was struggling in electronic futures market trading late Monday after the market’s parent, CME Group, again raised margin requirements on silver contracts -- an effort to cool speculative trading activity.
The increase in minimum margins, the cash deposits investors must put up or maintain to trade silver contracts, was the third by CME in a week. Effective at the close of business Tuesday the initial margin will rise to $16,200 per contract from $14,513.
