NEW YORK/LONDON, May 12 (Reuters) - Gold ended 1 percent higher on Tuesday as a weaker dollar and a wider U.S. trade gap prompted fund buying and bolstered the status of bullion as an alternative investment.
Traders said gold's rise was largely driven by the dollar weakness, which helped prop up the metal's appeal as an alternative investment.
Spot gold <XAU=> traded at $922.05 an ounce at 2:19 p.m. EDT (1819 GMT), up 1 percent from its late Monday quote of $912.60 in New York.
U.S. gold futures for June delivery <GCM9> settled up $10.40, or 1.1 percent, at $923.90 an ounce on the COMEX division of the New York Mercantile Exchange.
Bullion found support as the U.S. currency fell to a four-month low against a basket of currencies after data showed the U.S. trade gap widened for the first time in eight months, boosting investor risk appetite. [
].George Gero, vice president of RBC Capital Markets Global Futures, said that the U.S. trade gap news increased prices of energy and other commodities and bolstered investment interest in hard assets such as metals.
The rally in bullion -- often used as a hedge against market uncertainty and sometimes as a barometer of investor attitudes toward risk -- also came as oil and stock markets rose in the hope that the global economic slump may have bottomed out. [
]World shares, measured by MSCI's all-country index, initially hit a six-month high on Monday <.MIWD00000PUS>. Oil moved to its highest price this year of more than $60 per barrel <CLc1>.
Analysts have said gold prices are trapped between opposing forces as the precious metal's role as a hedge against economic uncertainty vies with perceptions that the economic downturn might be moderating.
"There's a lot of uncertainty still even though we have seen 'green shoots' rallies in equities, but is that the start of a recovery or a bounce in an otherwise bear trend? This is the great unknown," said James Moore, analyst at TheBullionDesk.com.
ETF HOLDINGS STABLE
The world's largest gold-backed exchange-traded fund, the SPDR Gold Trust <GLD>, said holdings stood at 1,104.09 tonnes as of May 11, unchanged from the previous business day. [
]Silver <XAG=> tracked gains in gold, rising to $14.21 an ounce, up 2.2 percent from its previous finish of $13.91 late in New York on Monday.
ETF Securities said its silver-backed ETF <PHAG.L> saw an inflow of more than 700,000 ounces on Monday, lifting its total holdings by 3.9 percent to a record 18.702 million ounces. [
]The company's head of research, Nicholas Brooks, said silver was benefiting along with other industrial precious metals from expectations the economic downturn may be bottoming out.
"People are looking at silver as a precious metal, but also a play on the cyclical upturn," he said. "It is really getting a substantial boost, and we are starting to see that in our ETC inflows."
Among other precious metals, spot platinum <XPT=> was at $1,127.50 an ounce, up 1.2 percent from its late Monday quote of $1,114.50, and spot palladium <XPD=> was at $232.50 an ounce, down 0.4 percent from its previous finish of $233.50.
