SINGAPORE, July 24 (Reuters) - Gold struck a two-week low on Thursday, losing some of of its safe-haven appeal after oil extended losses and stock markets rose, while platinum tumbled to its weakest in six months. Platinum has been hit by fears of falling demand from car makers, including General Motors <GM.N> and Toyota Motor Corp <7203.T>, due to a slowing U.S. economy. Autocatalysts account for around 35 percent of global demand for the metal.
Gold <XAU=> fell as low as $916.40 an ounce, its lowest since July 9, down from $921.35/922.95 late in New York on Wednesday -- well below a record high of $1,030.80 hit in March.
"Weaker oil prices, a stronger dollar, both of these are negative for gold. I just think there's a good possibility that we might see a continuation of a fall in oil prices," said Darren Heathcote of Investec Australia in Sydney.
"I've got to say I didn't foresee gold sort of breaking through the $936 area as easily as it did. But now it's here. We've got to be targeting $912-$904 or something like that," he said.
Oil <CLc1> extended losses and hit a seven-week low of $123.89 a barrel after data showed a larger-than-expected increase in domestic U.S. gasoline stocks last week. [

> climbed 1.27 percent.Declines in holdings on SPDR Gold Trust in New York, the world's biggest gold-backed exchange-traded fund <XAUEXT-NYS-TT>, to around 673 tonnes this week from a record above 705 tonnes in mid-July, suggested there was a shift to equities, said dealers.
In theory, a weaker oil price reduces gold's appeal as a hedge against inflation, and rising stock markets reduce its appeal as an alternative investment.
Platinum <XPT=> dropped to $1,715.00/1,725.00 an ounce from $1,744.00/1,764.00 an ounce. It tumbled to $1,703.50 an ounce on Thursday, its lowest level since late January.
"I am bearish on precious metals for now, particularly platinum and palladium. Their charts looks quite bad," said a dealer in Singapore.
"The next support is $1,684 but if we break this level, it's a long long way down to the $1,590 regions," he said.
Platinum struck a record at $2,290 in March after an electricity shortage that disrupted mining in main producer South Africa triggered speculative buying, but a combination of profit taking and demand fears erased most of the gains.
Spot palladium <XPD=> fell to $376.00/384.00 an ounce from $383.00/391.00 late in New York. It hit an intraday low of $371.50 an ounce, its lowest level since Jan. 25.
Palladium is also used in jewellery and autocatalysts.
Silver <XAG=> was steady at $17.32/17.40 an ounce compared with $17.33/17.38 late in New York, off a three-week low of $17.26 an ounce.
