NEW YORK, July 10 (Reuters) - Gold futures finished lower in quiet trade on Friday as the stronger dollar and tumbling oil prices signaled lingering worries over economic growth and diminished bullion's appeal as an inflation hedge.
The precious metal held above $900 an ounce but lost nearly $20 to end near a two-month low for the week. Gold was weighed down by deflation fears and broad-based commodities weakness stemming from U.S. regulatory pressure to limit speculation in energy and metals markets.
"People are now a little skeptical about whether the green shoots are actually happening, and that is taking a lot of momentum out of the gold market," said Tom Hartmann, analyst at California-based Altavest.
"There had been a lot of talk about inflation, inflation, inflation due to all the government spending, but none of that is going to happen until you have economic growth," he said.
U.S. August futures <GCQ9> settled down $3.70 at $912.50 an ounce on the COMEX division of the New York Mercantile Exchange.
Spot gold <XAU=> was at $912.85 an ounce at 2:20 p.m. EDT (1820 GMT), against $911.45 an ounce in New York late Thursday.
U.S. stocks extended losses on Friday. The Dow industrials and the S&P 500 were set for their fourth weekly drop as investors doubted whether companies can post sustainable earnings. [
]The mood of the equities market was soured by fresh data showing July consumer sentiment hit its lowest level since March.
Even with the stock market weakened by economic worries, bullion has failed to rise. Muted inflation concerns have sent flight-to-quality buying into U.S. Treasuries and the dollar.
A flight to quality could still boost gold in the future, but a lack of imminent inflation signals has been weighing on the metal's appeal as a hedge, market watchers said.
"I would not be getting aggressively long in gold for a long-term play until sentiment improves with stocks and the general economy," Hartmann said.
Other commodities also weakened. Oil, widely seen as the bellwether of the asset class, slipped more than $1 a barrel on Friday as economic pessimism deepened and traders worried about new rules to curb speculation. [
]The Commodity Futures Trading Commission, regulator of the U.S. futures market, will move aggressively to rein in excessive speculation in energy and commodity markets by focusing on expanding its existing authority and could have new regulations in place by late October. [
] [ ]Among other precious metals, platinum <XPT=> touched a low of $1,085, its weakest price since May 4, and was last at $1,103.50 an ounce an ounce versus $1,105, while palladium <XPD=> was at $232.50 versus $233.
A new General Motors <GMGMQ.PK> emerged from bankruptcy protection on Friday, far more quickly than most industry watchers had expected, and the company expected to repay loans to the U.S. government "much sooner" than 2015 as planned. [
]Traders focused on the potential market implications for autocatalysts related to GM's emerging from bankruptcy protection.
Silver <XAG=> slipped to a near 10-week low, pressured by strength in the dollar and reflecting losses in industrial metals such as copper on the weaker economic outlook. It was last at $12.63 an ounce, compared with its previous finish of $12.82.
COMEX options traders cited selling pressure related to heavy buying of December put options with strike prices of $12 and $11.75 an ounce. (Additional reporting by Jan Harvey in London; editing by Jim Marshall)
