While silver had a decent day, gold turned in yet another lackluster performance, ending October with a loss of 18%, the largest monthly decline for the metal in 28 years.

Gold was also held back as the dollar strengthened again vs. the euro, which offset any boost that might have been gotten from rising oil prices.

The reason for weakness in gold seems simple to Adrian Day, the president of Adrian Day’s Asset Management: “Global liquidation means more money from foreign assets are going into the dollar,” Day wrote. “The dollar is seen as a safe haven. There’s also liquidation of gold itself, which is easily sold.”

James Turk, the founder of Goldmoney.com, had a different take, though, saying that, “The dollar is in a short squeeze that won’t last much longer … Gold is dropping in dollar terms because of central-bank intervention and the massive deleveraging of dollar debt.”

The general sector weakness is also obviously playing in, with the Reuters/Jefferies CRB Index of 19 raw materials notching its steepest monthly decline since at least 1956.

“There’s significant pressure on all metals and commodities,” said Paul Sutherland, of Financial & Investment Group in Traverse City, Michigan. “Gold is not acting like a currency. It’s acting like a commodity. People are selling gold and gold shares because it’s something you can sell to raise cash.”
