LONDON, March 31 (Reuters) - Gold rose on Wednesday as the dollar slipped against major currencies and strong investment demand boosted sentiment, but prices are expected to be capped by technical resistance.
Platinum <XPT=> jumped to $1,646.50 an ounce, its highest since January 20 on worries about supplies from South Africa, the world's largest producer of the metal used to make auatcatalysts that clean car emissions.
Spot gold <XAU=> was at $1,108.65 a troy ounce at 1003 GMT from $1,102.50 an ounce late in New York on Tuesday.
The dollar hit a three-month high against the yen as strong dollar demand from Japanese importers for financial year-end book closing triggered widespread buying. [
]However, against a basket of currencies <.DXY> and the euro <EUR=> the dollar was lower, making dollar-denominated gold cheaper for holders of other currencies.
"Gold generally moves with the dollar," said John Meyer, analyst at investment bank Fairfax. "The flow of funds into ETFs (exchange traded funds) could mean a strong end to the quarter for metals, that will lead new money into the market."
The market is also watching Greece, which with its fiscal problems has dragged the euro <EUR=> down against the dollar in recent months. [
]That has weighed on gold, but uncertainty about finances in euro zone countries is a strong support.
"We view the upside risk as dominant today, supported by indications that Greece is starting to fail in raising money through bond issues," SEB said in a note. For a graphic on first quarter price performances, click on http://graphics.thomsonreuters.com/310/CMD_Q1PRF0310.gif
NO. 1 FURNACE
U.S. gold futures for June delivery <GCM0> gained $4.20 to $1,109.90 an ounce after falling on Tuesday due to month-end position squaring and contract rollover.
The world's largest gold-backed exchange-traded fund, SPDR Gold Trust <GLD>, said its holdings stood at 1,129.823 tonnes as of March 30, unchanged from the previous day, about 5 tonnes below a record high of 1,134.03 tonnes on June 1, 2009. [
]"Gold for the moment continues to consolidate with good volumes of physical and investment demand providing support," said TheBullionDesk.com in a note.
"However, the metal remains capped by overhead mid-term downtrend resistance and the 100-day moving average at $1,120, with another stalled rally potentially triggering a re-test of the $1,085 level." A break of $1,120 is possible, but it needs a strong trigger, one trader said, adding trading was subdued ahead of some key jobs data from the United States on Friday, which could help determine the future direction of the dollar.
"Platinum has had a good run today due to Lonmin."
The world's third largest platinum producer, Lonmin <LMI.L>, said it had shut its No. 1 furnace after another incident at the smelter, with repairs expected to take over a month.
The No.1 furnace, rebuilt last year, has a history of problems and has often forced the firm to cut sales guidance.
Lonmin said no one was hurt in Tuesday's incident and that its initial estimate was that a full repair would take around 30-40 days. The firm is aiming for 2010 platinum sales of 700,000 ounces. [
