LONDON, Aug 5 (Reuters) - Gold held near $965 an ounce on Wednesday, supported by a weaker dollar, while gains were limited by a lack of underlying demand for the metal from jewellers and exchange-traded funds.
Platinum and palladium built on the previous session's rise, with the threat of supply disruption in major producer South Africa taking the metals to multi-month highs.
Spot gold <XAU=> was bid at $964.20 an ounce at 1243 GMT, against $966.75 an ounce late in New York on Tuesday. That session it hit a high of $970.05, its strongest since June 5.
"The major forces that are affecting gold are the dollar on the one hand and ETF flows on the other," said Deutsche Bank commodities analyst Michael Lewis.
He said the dollar was at risk of falling still further, depressed by low interest rates coupled with a large fiscal deficit. "The exchange rate and interest rate environments still look quite supportive for gold."
He added that the dollar would have to weaken to $1.60 or $1.70 against the euro for gold to push past $1,000 an ounce. The dollar is now near $1.44 against the euro. [
]Weakness in the U.S. currency encourages more investors to move into hard assets such as gold, and makes dollar-priced commodities cheaper for holders of other currencies.
The dollar is holding near its lowest level this year, though it reduced its losses versus the euro after data showed U.S. employers cut more jobs than expected in July.
European shares also pared gains and U.S. stock futures turned negative after the ADP jobs report, which is seen as an important precursor to non-farm payrolls data due at the end of the week. [
] [ ]On the demand side, gold buying by ETFs, which issue securities backed by physical stocks of metal, remains weak. New York's SPDR Gold Trust <GLD>, the largest gold ETF, said its holdings were steady for a fourth day on Tuesday. [
]Meanwhile in India, the world's biggest gold consumer last year, bullion buying was hurt by rising prices. [

PLATINUM RALLIES
Gold's rise helped lift silver <XAG=> to $14.78 an ounce, a seven-week high, from $14.61 on Tuesday. It was later at $14.72.
Platinum and palladium rose on news unions are planning a strike at South African power utility Eskom, having already been lifted earlier in the week by positive July car sales data.
The National Union of Mineworkers, South Africa's biggest union, said it plans to strike at Eskom [
] next week after rejecting a wage offer, raising the threat of power disruptions that could disrupt metals production. [ ]"Although there is still uncertainty whether the strike action will go ahead, the newswire reports triggered buying activity in the (platinum) market," Standard Bank said in a note.
The bank said it sees a major strike by Eskom as "unlikely".
"Under South African labour law, Eskom is classified as an essential service and therefore most of its staff cannot go on strike," it said.
"Given the importance of stable electricity supply to the country's economy, we believe the possibility of government intervention in wage negotiations between Eskom and unions are also relatively high."
Spot platinum <XPT=> hit a high of $1,290 an ounce on Wednesday, its firmest since June 6, and was later at $1,281 an ounce against $1,265.50. Palladium <XPD=> rose to a new 11-month high of $281, and was at $276.50 against $274.50. (Editing by Anthony Barker)
