LONDON, Aug 19 (Reuters) - Precious metals languished in Europe on Tuesday after slipping sharply in Asian trade, as oil prices slipped and the dollar rallied to a fresh six-month high against the euro.
Platinum dropped more than 6 percent, gold by more than 2 percent and silver by 5 percent earlier in the session as Asian traders sold off the metals. Benchmark Tokyo platinum futures fell by their daily limit to a one-year low.
"Platinum closed in New York last night around $1,390 and this morning we hit a low below $1,300," said Afshin Nabavi, head of trading at MKS Finance. "That was the main reason for everything else coming off quite sharply."
Spot platinum <XPT=> was at $1,317.50/1,337.50 at 0953 GMT against $1,386.00/1,406.00 an ounce late in New York, having earlier touched a session low of $1,296.50.
The white metal is coming under pressure from fears slowing economic growth could dent demand from the automotive industry, which consumes more than half of the world's platinum.
Investment bank Investec cut its third-quarter price target for platinum on Tuesday to $1,660 an ounce from $2,050 an ounce, and sliced its full-year market deficit to 194,000 ounces.
The oil market also slipped on Tuesday, further weighing on the precious metals, and could decline further if Wednesday's U.S. oil inventory data shows stocks are rising.
"The consensus is looking for a strong build of crude oil inventories to be reported tomorrow," Dresdner Kleinwort consultant Peter Fertig said. "The outlook for weaker demand is probably pushing crude oil prices deeper to the south."
"Falling crude oil prices are another negative factor for gold and other precious metals," he added.
Lower crude prices tend to pressure gold in particular, both because it is often bought as a hedge against oil-led inflation and because weakness in oil dents interest in commodities as an asset class.
Oil fell below $112 a barrel on Tuesday as concerns over possible supply disruptions in the Gulf of Mexico eased as Tropical Storm Fay swept through the area with minimal disruption. [
]The firmer dollar is also weighing on interest in gold, which is often bought as a hedge against weakness in the U.S. currency.
The dollar resumed its upward march on Tuesday, rising to its highest level this year against a basket of currencies amid fears over slowing global growth, and hitting a six-month peak against the euro. [
]Gold and silver prices tracked platinum lower, pressured by oil and the dollar. Gold slipped to a session low of $782.05, before ticking back up to trade at $793.70/794.70 an ounce against $799.65/801.05 late in New York on Monday.
Gold prices have hit good support at $775 an ounce and should hold this level as interest in physical gold from jewellers is stoked by lower prices. Buying has picked up sharply in the last week as prices have fallen, traders say.
Among other precious metals spot palladium <XPD=> fell to $274.50/282.50 an ounce from $283.00/291.00 an ounce.
Silver <XAG=> slipped to $12.96/13.02 an ounce from $13.07/13.13 an ounce, having earlier touched a low of $12.45.
