CME Raises Silver, Gold Margins Again In Frantic Attempt To Kill Rally

``The CME has just raised its margin requirement on silver again, bringing maintenance margins up from $6,500 to $7,250, after hiking it less than a week ago for the first time and preventing silver from surpassing $30. Of course, why the CME is raising it more after the spot price of silver is now far lower than where it was at the first raise is a good question, but is most certainly due to the exchange's "risk mitigation" concerns, and has nothing to do at all with the intent to continue killing PM prices.
