Gold is started the week higher Monday as uncertainty deepened over Europe's financial crisis.

The price of gold often rises during times of financial uncertainty. Investors see the precious metal as a safe store of value and tend to turn to it instead of currencies or stocks when they're fearful. On Monday, doubts about Europe were stoked again as financial officials gathered in Brussels for urgent talks on how to ease the continent's debt crisis.
At the same time, political instability continued to roil Greece. The two main parties in that country were still trying to form an interim government that could impose austerity measures needed to avoid default.
Copper prices fell on pessimism about the economy and the housing market. Copper is used as a raw material in everything from electronics to new housing construction, so its price is closely tied with economic growth.
Fitch Ratings released a report that U.S. foreclosure rates have almost doubled from this time last year. Fitch said U.S. housing prices will probably fall another 10 percent before stabilizing. If that happens, it could hinder the construction industry and depress demand for copper.
