CME Group late Friday raised margin
requirements for some gold- silver- and copper-futures contracts, adding
pressure to metals prices Monday. The CME increased the so-called
initial margin by 21 percent to $11,475 per 100-ounce contract from
$9,450, pushing small investors out of the gold market as it raises the
cost to trade a futures contract. Gold futures sank as much as 8.5
percent in the two days following the last CME margin hike on August 25.
