European Central Bank President Mario Draghi said Dec. 19 that lenders in the euro region will experience "very significant" funding constraints next year and there are "substantial downside risks" to the economy. The Dollar Index rallied 2 percent this quarter as investors sold other assets for the perceived safety of the currency. The gauge declined in six of the past nine years and is 31 percent lower than at the start of that period.

'Hefty Declines'

"Going into 2012, there's a very, very high probability that we can see some fairly hefty declines in the commodity markets," said Stephen Hammers, the Nashville, Tennessee-based chief investment officer at Compass EMP Alternative Strategies Fund, which has about $500 million of assets. "There's a tremendous amount of uncertainty about what is going to happen around the world in terms of the global economy."

Pacific Investment Management Co., the world's largest bond fund, said the U.S. may stagnate next year. Europe may contract and Chinese growth may slow, Saumil H. Parikh, who leads Newport Beach, California-based Pimco's cyclical economic forums, said in a report posted on its website on Dec. 22.

The economy in China, the biggest consumer of everything from nickel to soybeans, may expand 8.5 percent next year, down from 9.2 percent this year and 10.4 percent in 2010, according to the median of 19 economist estimates compiled by Bloomberg.

$490 Million

Investors pulled $490 million from commodities funds in the week ended Dec. 21, according to data from Cambridge, Massachusetts-based EPFR Global, which tracks money flows. Gold and precious-metals outflows totaled $1.59 billion, and non- precious-metal commodities had net inflows of more than $1 billion, said Cameron Brandt, the director of research.

"Commodities, ex-gold, had one of their better weeks," Brandt said. "We are seeing some more durable faith in the U.S. recovery at the moment."

Confidence among U.S. consumers climbed more than forecast in December, to a six-month high, according to the Thomson Reuters/University of Michigan sentiment index. The increase to 69.9 from 55.7 in August is the biggest four-month increase since the period ended June 2009.

Builders broke ground in November on more U.S. houses than at any time in the past 19 months, led by a surge in multifamily units, the Commerce Department said Dec. 20.
