NEW YORK (Reuters) - Silver plunged more than 10 percent on Thursday, its biggest one-day drop in dollar terms since the Hunt Brothers price squeeze, dragging gold over 3 percent lower as panic selling snowballed across the commodities sector.
Silver has now lost 30 percent this week, well above the conventional criteria of 20 percent for a bear market, since it surged to a record high near $50 an ounce last Thursday. Silver’s plunge for a fifth day led the decline in commodities. The Reuters/Jefferies CRB index .CRB was set for its biggest weekly fall since late 2008 and U.S. crude oil fell below $100 a barrel.
Speculators in the silver futures market were forced to liquidate positions after the CME Group (CME.O) raised margins five times in under two weeks, an 84 percent rise in trading costs that has helped provoke a nearly unprecedented sell-off.
Other factors also weighed on the market, including signals that the European Central Bank was unlikely to raise interest rates next month, which triggered the biggest fall in the euro versus the dollar since November.
“It’s going to be a long time before silver can find a bottom to turn higher again,” said Dennis Gartman, publisher of the Gartman Letter.
“When you have this kind of damage, it will take several weeks or maybe several months for people to be taken out, and for confidence to be rebuilt,” said Gartman. “It’s not the end of the commodities cycle, not even close.”
Spot silver fell as much as 11 percent to a six-week low of $34.58 an ounce, down almost 30 percent so far this week. It was near the day’s low at $34.97 by 3:19 p.m. EDT (1919 GMT). The metal is also heading for its biggest weekly loss since at least 1983.
U.S. silver futures volume already topped 200,000 lots, more than three times above its 250-day average and one of the busiest trading days of 2010.
Widespread investor liquidation prompted gold to slide more than 3 percent to $1,461.57 an ounce, its lowest since mid-April.
Spot gold fell 3.2 percent to $1,4671.69 an ounce. COMEX June gold futures settled down $33.90 at $1,481.40, moving in a range from $1,462.50 to $1,522.10.
“This current sell-off is not commodity specific. It’s risk reduction across the market due to sluggish U.S. economic news such as the PMI and initial jobless claims,” said Hakan Kaya, commodities portfolio manager at Neuberger Berman, which manages more than $3 billion in commodities assets.
“This is just a temporary leveraging process, not the end of the bull cycle,” Kaya said.
CBOE gold volatility index .GVX, a gauge of bullion investor anxiety, spiked about 6 percent, ahead of Friday’s key U.S. non-farm payrolls data, which should offer evidence of the ability of the economy to generate jobs, something which the Federal Reserve has flagged as a key concern.
Silver selling pressure was accelerated by extremely bearish investor sentiment, as global holdings of silver in exchange-traded funds staged their biggest one-day decline this year.
Silver’s decline sent the gold/silver ratio, which measures how much silver an ounce of gold can buy, to an eight-week high above 40 from just below 32 last Thursday.
Technicals were again in focus after silver broke below its 50-day moving average, which had held since February, after it breached 20-day MA earlier this week. But prices were still well above the 100- and 200-day averages, after silver rallied as much as 170 percent over the last 12 months.
CitiFX chief technical strategist Tom Fitzpatrick said the only reference available to chart its current path was the dramatic slide off the previous all-time high in 1980, which took it down from $50 down to $30 in pretty much a straight line.
“Was silver a bubble? I think to a large extent it was. It’s notoriously volatile. The fundamentals of silver are simply not as good as gold‘s,” said Stephen Briggs, analyst at BNP Paribas.
Investors scrambled out of physical silver, as reflected by the 15.3 million-ounce fall on Thursday in metal holdings in global ETFs, with the world’s largest -- the iShares Silver Trust staging the second-biggest one-day fall since its inception in 2006. <GOL/ETF>
Also weighing down on investment sentiment was news Mexican billionaire Carlos Slim’s Minera Frisco (MFRISCOA1.MX) mining company increased its short position in the silver market in the first quarter to fund its development program.
Among platinum group metals, platinum fell 3.4 percent to $1,755.74 an ounce and palladium dropped 5.5 percent to $702.72.
