LONDON, July 29 (Reuters) - Gold eased in Europe on Wednesday as the dollar firmed on rising risk aversion, which prompted losses across commodities and put currencies seen as higher-risk under heavy selling pressure.
Spot gold <XAU=> was bid at $934.65 an ounce at 1143 GMT, against $936.35 in early trade. U.S. gold futures for August delivery on the COMEX division of the New York Mercantile Exchange <GCQ9> slipped $4.30 to $934.80 an ounce.
Precious metals fell along with many other commodities, such as oil and copper, after a slide in Chinese equities hit risk appetite and lifted the dollar versus a basket of currencies.
Chinese stocks <
> dropped 5 percent on Wednesday, their biggest daily drop in eight months and ending a five-day rally, on concerns banks could restrict lending. At one point, equities were close to 8 percent lower. [ ]"There is some concern that the (Chinese) government could try to tighten up credit conditions in China, which could be negative for lots of stock markets and therefore positive for gold," Daniel Smith, an analyst at Standard Chartered, said.
At 1143 GMT, the dollar <.DXY> was up 0.49 percent at $79.11 against a basket of major currencies. U.S. data showing U.S. durable goods orders is due at 1230 GMT, but is not expected to have a major impact on the market.
"The dollar is seen as a safe haven, so if... people feel assured about recovery, they are happy to sell the dollar and buy risk assets such as commodities," said Citigroup analyst David Thurtell.
"If you have wobbles over China, the dollar picks up, and commodities come off," he said.
In a note, MF Global said talk about anti-speculation measures by the U.S. Commodity Futures Trading Commission (CFTC) could also add to selling pressure.
Oil <CLc1> fell towards $65 a barrel, while copper hit its lowest level in a week on rising risk aversion. [

SLOW DEMAND
Investment demand for gold remained lacklustre, with a further 3.36-tonne outflow from the world's largest bullion-backed exchange-traded fund, the SPDR Gold Trust, adding to a recent retreat in ETF holdings. [
]Physical demand for gold remains soft overall, with seasonal weakness and high prices hurting consumption in the key Indian and Middle Eastern markets. This weakness in underlying demand makes gold vulnerable to a sell-off, analysts said.
"Given the recent build in speculative longs and ETF redemptions yesterday, combined with very limited physical interest, gold remains vulnerable to a deeper correction," said James Moore, an analyst at TheBullionDesk.com, in a note.
On the supply side, the World Gold Council said official sector sales under the Central Bank Gold Agreement currently stand at just 140 tonnes so far this year, well below the total 500 tonnes allowed under the pact. [
]Among other precious metals, platinum <XPT=> was at $1,174 an ounce against $1,187.50 early on Wednesday, while palladium <XPD=> was at $254.50 against $255.
The two metals climbed to multi-week highs earlier this week as firmer stocks boosted hopes demand for the autocatalyst materials would pick up. However, analysts say the uptick in the dollar is being used as an opportunity to take profits.
Silver <XAG=> was at $13.55 an ounce against $13.69. (Editing by Sue Thomas)
