Metals prices jumped Tuesday on expectations that demand may improve after a new Greek bailout package was approved and China took another step to stimulate economic growth.
Silver finished up 3.7 percent, while prices for platinum, copper and palladium all rose 3 percent or more. Gold ended up 1.9 percent.
Investors have been concerned about the impact on commodities demand from Europe's financial problems and a possible economic slowdown in China, the world-second largest economy.
After months of back-and-forth negotiations, leaders of countries that use the euro approved a multi-billion dollar funding package Tuesday for Greece. The country likely would have defaulted on its debt next month without getting more bailout money. A default could have triggered another financial crisis and created more problems for the European economy.
Last weekend, China's central bank said it will lower the ratio of funds Chinese banks must hold as reserves. The policy change is designed to free up more money for lending as a way to promote economic growth. It was the second time in two months that China's central bank has cut reserve requirements. China is a huge importer of raw materials.
