In the international markets, gold rose 0.1 percent, to 1,643 dollars an ounce, today, as a better-than-expected German business sentiment survey lifted the euro versus the dollar. Prices are set to fall 1 percent this week, despite holding within their narrowest weekly range in more than a year. But gold is struggling for direction as buyers await the outcome of International Monetary Fund and World Bank meetings this weekend, at which plans to tackle the euro zone debt crisis will be discussed, and a U.S. Federal Reserve meeting next week.
