4.1 National supervisors should develop their own list of eligible collateral assets based on the key principle, taking into account the conditions of their own markets.  As a guide, examples of the types of eligible collateral that satisfy the key principle would generally include:

CME Group Hiking Silver-Futures Margins By Another 11.6%

I view each margin hike as short-term negative for any commodity, as weak longs liquidate, but long-term it remains bullish for silver because buyers of physical bullion buy at discounted prices and provide a floor for the silver market.

CME raises precious metals margins requirements--again

In another desperate attempt to knock down the futures prices of gold and silver, the CME raised the margin requirements on gold and silver futures contracts.

I hope they raise the margin requirements to 100%, so there will be no leverage allowed. Although that would bankrupt the GLD and SLV ETF's, which are not 100% backed by physical inventory.

The more they play the price suppression game, the tighter the noose around their own necks. Buy physical.

Of course, only margin requirements for non-member speculators were raised, while member firms' margin requirements were not. Gee, while some members are accused of rigging the game, the CME decides to punish the non-members. How's that for justice?
