Copper (XCU) prices enter the week with positive momentum as a weaker U.S. dollar and fresh policy support from China improve the demand outlook. But higher Treasury yields and tensions in the Middle East may limit the rally. The technical structure remains constructive above $6 with $6.80 acting as the key level for further gains. Meanwhile, the ratios between copper, gold (XAU) and silver (XAG) show that precious metals may continue to outperform copper in the short term.
