LONDON, Sept 14 (Reuters) - Gold hit record highs above $1,260 an ounce on Tuesday in its biggest one-day rally in four months as the U.S. dollar declined broadly after upbeat data failed to convince investors to shift into risk-linked assets.
Spot gold <XAU=> was at $1,265.30 an ounce by 1400 GMT, up from $1,245.25 the day before, having hit a record high of $1,267.20 earlier in the session. U.S. gold futures for December delivery <GCZ0> were last up $19.9 an ounce at $1,266.80.
"The funds are certainly doing some buying ... who else is it going to be? It's not producers buying it back, it's investors. And investors, whether rightly or wrongly, believe in this and that is the message," said ANZ head of sales Peter Hillyard.
"It's going up for all the same reasons. People are fearful still. Little things come into the market, little factors that awaken people's interest in gold," he said.
The dollar extended losses on Tuesday to hit 15-year lows against the Japanese yen and plumbed nine-month lows against the Swiss franc, another key safe-haven asset, while euro zone government bond yields also declined. [

Gold is on track for a 15 percent rise this year, fuelled primarily by investors seeking an alternative to volatile currencies, equities and some sovereign bonds as economic data has cast doubt on the global growth outlook.
"All four precious metals are really keeping a very close eye on the U.S. dollar right now and if the dollar doesn't 'shape up,' as such, this safe-haven buying will continue in the precious metals," said Afshin Nabavi, head of trading at MKS Finance.
Although the gold price has held within a few dollars of record highs for a few weeks, the market is now in the full throes of the buying season in some of the world's biggest consumers, who seem undeterred by the price strength.
Across the rest of the precious metals complex, silver traded at its highest in 2-1/2 years, helped by robust Chinese industrial output and firm base metals, although the safe-haven effect boosting gold was also a driving force. [
]Spot silver <XAG=> was last at $20.32 an ounce, up from $20.02 the day before and on course for its third consecutive day of gains.
In the platinum group metals, palladium <XPD=> hit its highest in four months, trading just shy of $550 an ounce.
Palladium, which is predominantly used in the production of auto catalysts, is on track for a 33 percent increase this year and is one of the top performers of the commodities complex.
Palladium was last at $548.00 up from $524.95 on Monday, set for its biggest daily rally since late May, while sister metal platinum <XPT=> was last quoted at $1,575.00 an ounce, up from $1,543.65 the day before and around six-week highs. (Editing by Sue Thomas)
