Metal, energy prices rally as dollar weakens

NEW YORK — Prices for copper, silver and other metals roseThursday as a weaker dollar and the promise of an economic recovery lured investors to commodities.

Commodities prices advanced despite Thursday’s disappointing retail sales report that showed consumers are still too worried about their jobs to spend freely. Government reports showed retail sales unexpectedly fell in July, while the number of first-time claims for unemployment were higher than projected.

But investors looked past the day’s news, and continued buying in response to the Federal Reserve’s more positive assessment of the economy that helped carry stocks and commodities higher on Wednesday.

“These markets are hanging in there,” said Matt Zeman, head trader at LaSalle Futures in Chicago. “Equities have been very resilient and commodities have been following suit.”

Major stock indicators wavered, but managed to hold on the prior day’s big gains. Commodities got an extra push from a weaker dollar, which fell further against the euro and the British pound. Commodities are priced in U.S. dollars so foreign investors tend to buy more when the greenback is falling.

On the New York Mercantile Exchange, September copper futures rose 9.05 cents, or 3.2 percent, to $2.9140 a pound. Aluminum prices jumped 4 percent.

Among precious metals, September silver soared 40.2 cents, or 2.7 percent, to $14.9870 an ounce, while October platinum rallied $28.30, or 2.3 percent, to $1,272.70 an ounce.

Gold for December delivery added $4 to $956.50 an ounce.

A weaker dollar also lured investors to energy commodities. Oil prices gained 36 cents to settle at $70.52 a barrel.

Heating oil rose 1.07 cents to $1.9028 a gallon, while gasoline for September delivery gave up less than a penny to close at $2.0192 a gallon.

Natural gas prices, which have underperformed the rest of the energy market this year, lost 14.3 cents to $3.336 per 1,000 cubic feet.

Among soft commodities, cotton and cocoa were higher, while coffee and sugar prices declined.

Soybean and corn futures retreated on the Chicago Board of Trade after two days of gains.

November soybeans dropped 25.25 cents to $10.1875 a bushel, while corn for December fell 4.25 cents to $3.32 a bushel.

December wheat futures lost 8.5 cents to $5.0925 a bushel.
