LONDON, Aug 4 (Reuters) - Platinum extended losses in Europe on Monday after a weak session in Asia, as investors worried about the outlook for the automotive industry after monthly U.S. car sales slipped to a 16-year low.
Around half of global platinum supply is used by the automotive industry in catalytic converters, so any slowdown in car manufacturing could have a major impact on demand.
Spot platinum <XPT=> fell to $1,617.50/1,637.50 an ounce at 0850 GMT from $1,646.50/1,666.50 an ounce late in New York. Earlier it slid as much as 2 percent to a session low of $1,612.50, its weakest level since January 25.
Sister metal palladium <XPD=> was little changed at $363.50/371.50 an ounce from $364.00/372.00 late in New York.
In Asia, the most active contract on Tokyo platinum futures <0#JPL:> slid by its daily 300-yen limit to its weakest since late January as speculators sold their contracts.
"If platinum falls to around $1,450, and palladium to $320, we might see some mines... starting to lose money," said Standard Bank analyst Walter de Wet. "That is probably a short-run floor in prices."
"The other big question is (whether) the market is still in deficit," he added. "A lot of investors have got rid of platinum, and demand is also now falling behind supply. If we're not in a deficit any more, $1,500 is a possibility."
The demand drop is largely a result of a slowdown in the car industry. U.S. car sales slipped to a 16-year low in July, led by a 27 percent drop at General Motors Corp <GM.N>. High gasoline prices and tight credit are buffeting the industry. [
]On Friday spot platinum shed $100 an ounce after General Motors lost another $15.5 billion, BMW issued a profits warning and Nissan earnings fell far short of expectations. [
]Investment demand for platinum also appears softer. London-based ETF Securities said its Physical Platinum ETF <PHPT.L> has seen outflows of over 42,000 ounces, or 11 percent, over the last month.
Earlier this year platinum spiked up to an all-time high of $2,290 an ounce on fears a power shortage in major producer South Africa could seriously deepen the metal's supply deficit this year.
GOLD REBOUNDS
Gold prices ticked up as a rebound in crude prices encouraged buying of the precious metal as a hedge against oil-led inflation.
Oil climbed as a tropical storm formed near the Gulf of Mexico, seat of key U.S. oil installations, and as fresh violence broke out in OPEC oil producer Nigeria. [
]The dollar came off a five-week high against the euro on the back of oil's high, further supporting gold's move. [
]The precious metal typically moves in the opposite direction to the U.S. currency, as it is often bought as a hedge against dollar weakness.
The firmer tone the currency has taken in recent weeks is raising fears over the outlook for gold.
"The deterioration in German economic activity and Euroland capital flows are increasing the possibility of short-term strength in the US dollar," said Deutsche Bank in a note.
The market will be looking to a spate of central bank meetings this week, including Federal Reserve talks on Tuesday, to lend fresh direction to the foreign exchange markets.
In investment news, gold holdings of the world's largest gold-backed exchange traded fund, the SPDR Gold Trust <GLD>, edged up 0.1 percent to 674.02 tonnes on Friday, the trust said.
Spot gold <XAG=> rose to $912.65/913.65 an ounce from $909.85/911.45 late in New York on Friday.
Among other precious metals, spot silver <XAG=> edged up to $17.56/17.62 an ounce from $17.47/17.55 late in New York.
