Comex Raises Copper Margin Requirements -- Gold & Silver Next? (CME, FCX, SCCO, NEM, ABX, SLW, JJC, GLD, GDX, GDXJ, SIL)

In what appears to be a counterintuitive move, CME Group (NASDAQ: CME) today raised its margin requirements for copper futures contracts. The requirement rose by 15%, from $6,750 to $7,763 for an initial contract and from $5,000 to $5,750 on a maintenance contract. That works out to a margin cost of about 9.6% on a new contract for 25,000 pounds of copper at around $3.24/pound.

Copper prices have dropped by more than $1/pound from around $4.50/pound at the beginning of August. CME raised the copper margin by 18% on September 24th, so this is the second rise in just over two weeks. At the same time as the last rise, CME also raised the margin requirements on gold by 21% and silver by 16%. CME’s rationale for raising margin requirements is based on what it calls a “normal review of market volatility to ensure adequate collateral coverage.”

CME’s move has probably played a part in lifting copper mining stocks Freeport-McMoran Copper & Gold (NYSE: FCX) and Southern Copper (NYSE: SCCO), as well as gold miners Newmont Mining (NYSE: NEM) and Barrick Gold (NYSE: ABX), and silver miner Silver Wheaton (NYSE: SLW).

If copper margins are rising today, can requirements on gold and silver be far behind? The margin requirement for a speculative trader to open a position on a 100-ounce gold contract is $11,475. At today’s price of around $1,648/ounce, that is just 7% of the value of the contract.

The margin requirement for a speculative 5,000-ounce silver contract is $24,875. At today’s silver price of nearly $32/ounce, the value of a contract is $160,000. That calculates to a margin requirement of about 15.5%.

The rise in margin requirements last month put a damper on prices for all three of the metals. That is not happening with copper today, as the price is up nearly 5%. The news that the European Central Bank is offering essentially unlimited additional emergency loans to eurozone banks is putting some air under all markets today, and the commodities markets are not excepted.

Still, there is a nearly certain chance that CME will lift its gold and silver margin requirements again. The margin on gold contracts seems particularly out of kilter given the 15% requirement for both silver and copper. But if today’s market reaction is any indication, margin requirement increases do not play as big a role in metals trading as might be thought.
