UPDATE AT 9 PM ON OCTOBER 6

Copper fell the most in 13 months in London and aluminum

slumped to almost a three-year low as the credit crisis

deepened, threatening to curb global demand for raw materials.

The London Metal Exchange index of six metals tumbled 9.6

percent last week, the most since July 2006. Declines in all

commodities accelerated as Goldman Sachs Group Inc. said

the U.S. economy will enter a recession ``significantly deeper''

than previously forecast.

Copper for delivery in three months fell as much as 7.7 percent to

$5,545 a metric ton, the biggest intraday drop since Aug. 16, 2007.

It traded at $5,610 a ton as of 12:25 p.m. local time. Aluminum fell

as much as 3.9 percent to $2,248 a ton, the lowest since January 2006.

Copper stockpiles monitored by the LME gained 250 tons to

198,750 tons, according to the exchange's daily report.

Open interest of copper futures has risen 13 percent to 275,423

contracts since the end of June while prices have lost 34 percent,

reflecting new short positions are being added. Increasing short

positions on the LME could mean either more bets on price

declines, or producers are hedging against further metal weakness.
