NEW YORK/LONDON, March 23 (Reuters) - Gold rose to within a whisker of its all-time high on Wednesday, as disappointing U.S. housing data, renewed euro zone debt fears and ongoing Western air strikes on Libya increased the metal's safe-haven appeal.
Bullion rose to less than $5 below its record $1,444.40 an ounce set on March 7, after a report showed the U.S. housing market slide was deepening, as new U.S. single-family home sales unexpectedly fell in February to hit a record low and prices were the lowest since December 2003. [
]"The new home sales data inspired some to think that we may not see the demise of QE2, and we are going to see money printing continue past its potential expiration at the end of June," said Mark Luschini, chief investment strategist of broker-dealer Janney Montgomery Scott with $53 billion assets under management.
"That would likely mean more stimuli and more prospect for inflation, and that's gold friendly," he said.
Spot gold <XAU=> rose 0.6 percent $1,438.55 an ounce by 12:03 p.m. EDT (1603 GMT). The precious metal hit a session high of $1,440.90, its highest since March 7.
While commodity markets were mostly quiet on Wednesday, gold was one of the most actively trading markets with volume approaching 125,000 contracts at midday.
Spot silver <XAG=> soared above $37 an ounce, its highest since 1980. It later gained 1.5 percent to $36.88 an ounce.
Year to date, silver has gained nearly 20 percent, and gold was up just over 1 percent. Silver was boosted by near-term supply tightness and strong industrial demand on expectations the global economy continued to recover.

Gold has benefited tremendously as a hedge against currency depreciation since last November, when the Federal Reserve announced its plan to increasing money supply by buying $600 billion of long-dated U.S. Treasury bonds to boost growth, a process known as quantitative easing.
The latest flurry of gold purchases was also bolstered by the expectation Portugal's parliament would reject the government's latest austerity measures, and that rekindled euro zone debt worries ahead of a summit of the economic bloc. [
]Both platinum and palladium, mainly used as autocatalysts in vehicles, have come under pressure since Japan's March 11 earthquake and tsunami shut car factories in Japan.
Platinum <XPT=> climbed 0.6 percent to $1,743 an ounce and palladium <XPD=> gained 1.2 percent to $741.97 from $733.
Toyota Motor Co <7203.T> has halted operations at its 12 main assembly plants in Japan until at least Saturday, which will result in lost production of 140,000 vehicles. Other major car makers also have yet to resume full production due to a shortage of parts and workers. [
