* Gold edges below $800 again, dollar weighs
* Platinum extends losses; TOCOM at 1-year low
* Oil slumps $1 as strong dollar counters storm fears (Updates prices)
SINGAPORE, Sept 9 (Reuters) - Gold slipped below $800 on Tuesday after the dollar struck a one-year high against a basket of other currencies, prompting speculators to ditch their holdings and shift some of their money back to currencies.
Other precious metals also dropped, with platinum falling almost 2 percent on worries about demand for autocalysts due to poor car sales in key markets such as the United States, Japan and China. Tokyo platinum futures hit a 1-year low.
Gold <XAU=> fell 0.4 percent to to $798.55/799.55 an ounce from $802.25/803.60 an ounce late in New York on Monday, having hit an intraday high of $803.50 an ounce.
Bullion has fallen more than 19 percent since hitting a four-month high of $987.75 an ounce in mid-July but stabilised around $800 an ounce -- still up 14 percent from a year ago.
Gold was well below a lifetime high of $1,030.80 hit in March and within sight of a nine-month low of $773.90 struck in mid-August. Festive demand especially from main consumer India was likely to offer support at lower levels, dealers said.
"The dollar's strength has pulled down the gold market. But it looks like there's a bit of support at below $800," said Ronald Leung, director of Lee Cheong Gold Dealers in Hong Kong, referring to physical demand from jewellers.
The dollar index <.DXY>, a gauge of the greenback's performance against a basket of six currencies, hit another one-year high on Tuesday after the U.S. government seized control of Fannie Mae <FNM.N> and Freddie Mac <FRE.N>. [
]"The range is maybe between $780 and $820 for the time being. Speculators are only on the selling side. They may buy back on short covering," said Leung.
India is stepping up purchases during the festive season, which peaks in October with Diwali, the Hindu festival of lights. Dealers also saw purchases from jewellers in Indonesia ahead of the Eid al-Fitri Muslim holidays in October.
Investors also watched oil for direction after U.S. crude futures <CLc1> fell more than $1 as traders shed their commodity positions to join the rally in the dollar and anticipated OPEC would keep output targets unchanged at Tuesday's meeting. [
]Spot platinum <XPT=> fell 1.8 percent to $1,312.50/1,334.50 an ounce from $1,337.00/1,357.50 late in New York on Monday, when it tumbled nearly 4 percent.
Worries about falling demand for autocatalysts, a slowing U.S. economy and profit-taking have dragged down platinum by more than 40 percent from its record high of $2,290 in March.
The benchmark platinum contract on the Tokyo Commodity Exchange, August 2009 <JAUc6>, ended the morning session 212 yen per gram lower at 4,502 yen, having hit an intraday low of 4,484 yen -- its weakest since late August 2007.
"Fund money has shifted out of the commodities markets to stocks and currencies. It's a bearish mood in Tokyo commodities markets," said Kazuhiko Saito of Interes Capital Management in Tokyo.
"Demand is very bad. Automakers are not buying," said Saito, adding that ash platinum may trade below $1,200 by end-September, referring to a level last seen in March 2007.
Autocatalysts, used to clean exhaust fumes, account for more than 50 percent of global demand. China's passenger car sales fell in August from a year earlier, the first monthly decline in more than two years as a slowing economy and the Beijing Olympics kept would-be car buyers from showrooms. [
