Industrial metal prices rose Monday as a weaker dollar makes the raw materials more expensive.
The U.S. dollar fell versus the euro Monday. That makes metals like copper and platinum more expensive because they are denominated in dollars.
The euro rose as talks progressed to ease Greece's debt crisis. European finance ministers put pressure on Greece's private creditors to reach an agreement with Athens to cut the country's massive debt load. If the creditors agree to a plan, it could help Greece reduce its debt and avoid missing a vital bond repayment deadline.
The Greek government and representatives for the private creditors said they are moving closer to a final deal.
If Greece can begin solving its debt problems, it would ease a financial crisis that has undermined the value of the euro. The euro rose about one penny to $1.30 Monday, close to its highest level against the dollar this year.
