NEW YORK, July 29 (Reuters) - Gold rose on Thursday after comments by top U.S. Federal Reserve officials stirred economic uncertainty, but a sharp outflow in the world's largest gold exchange traded fund signaled possible near-term liquidation.
Palladium, which is mostly consumed by the car industry as an autocatalyst, rose 4 percent on a strong euro and options-related buying, traders said. The metal posted its biggest one-day percentage gain since late May.
COMEX gold open interest, an indicator of overall market and fund trading activity, lost 4 percent on Wednesday, as trading volume hit an all-time high, indicating investors are moving out of the precious metal into equity markets. [

Bill O'Neill, partner of New Jersey-based commodity firm LOGIC Advisors, said gold rose largely due to economic jitters after comments by the two Fed officials, but the drop in investment demand signaled prices could fall further.
"Gold is higher because we have some nervousness surrounding other markets, but we could see speculative liquidation as it (GLD tonnage drop) shows there is no flight-to-safety type buying," O'Neill said.
SPDR Gold Trust <GLD>, often called GLD because of its ticker symbol, posted its biggest one-day tonnage drop since April 2008, as holdings fell 18.55 tonnes to 1,282.28 tonnes on Wednesday.
Spot gold <XAU=> was at $1,168.10 an ounce at 3:17 p.m. EDT (1917 GMT), against $1,162.55 late in New York on Wednesday, when it hit a three-month low at $1,156.90. U.S. gold futures for August delivery <GCQ0> settled up $8 at $1,168.40.
Gold prices have struggled to maintain higher levels since hitting a record $1,264.90 an ounce in June, with investors liquidating gold holdings in favor of other assets as equities recovered some of the losses made earlier this year.
On Thursday, St. Louis Fed President James Bullard said he is worried about the risks the United States could fall into a Japan-style quagmire of falling prices, sending Wall Street as much as 1 percent lower. [
]Gold largely held its initial gains even as U.S. stock markets recouped most of their losses in late sessions.
Bullion also benefited from comments by Dallas Fed President Richard Fisher, who said any further monetary policy accommodation from the Fed would have as little effect boosting the economy as "pushing on a string." [
]PALLADIUM AT HIGHEST SINCE JUNE
On the physical side of the market, traders reported good buying for a fourth day in major gold consumer India, as they stock up ahead of festivals on the subcontinent. [
]However, investment demand for physical bullion in Europe has softened as concerns over the stability of the financial system recede. This is set to keep prices under pressure.
On the wider markets, the dollar weakened against the euro <EUR=> to its lowest since early May. Sharper appetite for risk is lifting the appeal of higher-yielding currencies. [
]Palladium <XPD=> rose to its highest level since late June at $488 an ounce and was last at $483.50 versus $465.93.
Traders cited a stronger positive correlation between palladium and the euro. Heavy call-option buying in palladium also boosted future prices, they said.
Silver <XAG=> was at $17.58 an ounce against $17.44, and platinum <XPT=> was at $1,558.50 an ounce versus $1,531.75. Prices at 3:31 p.m. EDT (1931 GMT)
