* Platinum, palladium hit multi-month highs on supply threat

LONDON, Aug 5 (Reuters) - Gold held near $965 an ounce in Europe on Wednesday, supported by the softer dollar, but gains were limited by weakness in underlying demand for the metal.
Platinum and palladium built on the last 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 $965.30 an ounce at 0955 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.
"There are definitely risks that the dollar could go even weaker," he said. "The dollar could still be moving lower throughout next year."
Weakness in the U.S. currency is encouraging more investors to move into hard assets such as gold, as well as making dollar-priced commodities cheaper for holders of other currencies.
The dollar is holding near its lowest level this year and analysts see a risk of further declines as the global economy shows signs of improvement. [
]Optimism over the outlook for the markets was supported by a rise in European equities on Wednesday after a pause in their upswing the day before, while oil remains near year-highs above $70 a barrel, albeit a touch down on the day. [
] [ ]"The U.S. dollar is at year lows to all major currencies with the exception of the (yen) and the U.S. and many other global equity markets are at the year highs," said HSBC analyst James Steel in a note.
"Additionally, oil prices are close to year highs, as are many other commodities," he said. "These factors are supportive of the gold price."
DEMAND
But gold buying by ETFs, which issue securities backed by physical stocks of a given metal, remains weak. The largest gold ETF, New York's SPDR Gold Trust <GLD>, said its holdings were unchanged for a fourth day on Tuesday. [
]ETF Securities said the three gold-backed ETFs it operates saw outflows of nearly 25,000 ounces on Tuesday.
In India, the world's biggest gold consumer last year, bullion buying was hurt by rising prices. [
]Gold's rise helped lift silver <XAG=> to $14.73, a seven week high. It was later at $14.72 an ounce against $14.61.
Platinum and palladium also hit new multi-month highs. The metals are taking support from news that 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. [ ]"We've seen a lot of speculative buying coming into the market on the back of the Eskom news," said Commerzbank trader Rory McVeigh
"The whole move in the price is speculative positioning. We're still seeing very, very thin demand for the physical metals," he added. "We'll probably see a push to get platinum up to $1,300 today."
Spot platinum <XPT=> hit a high of $1,290 an ounce on Wednesday, its firmest since June 6, and was later at $1,276 an ounce against $1,265.50. Palladium <XPD=> rose to a new 11-month high of $281, and was at $279 against $274.50. (Additional reporting by Catherine Bosley; Editing by Sue Thomas)
