* Fed seen cutting rates by at least 50 bps * Dollar slips vs euro as risk appetite returns * Oil climbs on hopes of U.S., Japanese rate cuts (Updates prices)

LONDON, Oct 29 (Reuters) - Gold jumped nearly 4 percent in Europe on Wednesday on dollar weakness and a rise in oil prices, as traders awaited the U.S. Federal Reserve's key decision on interest rates due later in the day.
Gold's rally boosted silver nearly 10 percent and helped platinum to bounce after a sharp fall due to demand worries, while palladium also soared 10 percent on bargain hunting.
Spot gold <XAU=> rallied to $773.40 an ounce and was quoted at $765.20/767.70 an ounce at 1532 GMT, against $744.30 in late New York trade on Tuesday.
New York December gold futures <GCZ8> were up $25.80 at $766.30 an ounce.
Mitsubishi precious metals strategist Tom Kendall said the rise was partly because of weaker dollar and also due to rising commodity and equity markets across the board.
"We see buying coming back in across a lot of asset classes. I think the selling from last week proved to be a little bit of overdone," he said.
Kendall added the anticipation of a rate cut from the Fed was another element that boosted prices.
The dollar fell against other major currencies, as rising stock markets boosted risk appetite and traders factored in a substantial Fed rate cut later in the day. [
]"After a 66 percent probability of a 50 basis point rate cut yesterday, interest rate futures now pencil in 62 percent - which demonstrates the uncertainty of financial market participants," said Standard Bank analyst Manqoba Madinane.
China cut interest rates on Wednesday for the third time in six weeks to help the world's fourth-largest economy ride out the reverberations of the global financial crisis.
Rises in other commodity markets help boost gold prices. Copper surged nearly 8 percent and lifted other industrial metals higher while oil rose more than $5 to above $67 a barrel, boosted by a recovery in global stock markets.
European shares were up nearly 5 percent, tracking gains in Asia, though Wall Street struggled against profit taking.
Firmer crude typically benefits gold, which is often bought as a hedge against oil-led inflation. Rising oil prices also tend to boost interest in commodities as a whole.
"The recent movements in both the equity and currency markets suggest some risk appetite is beginning the return," said James Moore, an analyst at TheBullionDesk.com.
"This, coupled with the fact gold is considerably lower than at the start of the year and investors may look to further diversify their asset holdings, given recent events, may allow gold to begin recouping some of its losses."
Platinum <XPT=> at $799.50/829.50 an ounce, bouncing from an earlier session low of $755.50 an ounce, versus $809.00 on Tuesday.
Buying of the metal for use in catalytic converters accounts for more than half of global platinum demand, and reports of production cutbacks and falling sales among car manufacturers have wiped 65 percent from the metal's value since March.
However, analysts said the fall may have been overdone.
"There is little downside risk left in the platinum group metals sector since PGM metal prices are sufficiently low that supply is likely to be removed from the market," investment bank Nomura said in a research note.
"Fears of a steep decline in global auto sales and hence autocatalyst demand, in view of a global recession, are already priced in to the extreme."
Palladium <XPD=> was at $192.50/202.50 from $176, having surged more than 10 percent to a two-week high of $195 on speculation the sell-off in the metal was overdone.
Spot silver <XAG=> was at $10.01/10.11 an ounce, after rising to $10.02, against $9.16. (Additional reporting by Humeyra Pamuk; editing by Karen Foster, Editing by Peter Blackburn)
