The U.S. Dollar Index, which is down this year, has another 10% left to fall to keep pace with 2008 lows. Efforts to stimulate the economy are contributing to a weak dollar versus the euro, a trend that would help sustain gold's long-term rise.

The U.S. economy lost another 216,000 jobs in August, boosting the unemployment rate to a 26-year high of 9.7%, the Labor Department said today. That means stimulus efforts are likely to continue, and a new low for the dollar may trigger the spot price of gold to blast past the March 21, 2008, high of $1032.70.
