Ero Copper is trading at $32.17 (-4.48%) on September 15, 2026, as copper prices continue retreating from recent records amid uncertainty over potential U.S. tariffs on refined copper.
- The decline appears sector-driven rather than company-specific, with copper miners broadly selling off after the tariff-related reversal.
- Broader markets are also weaker as Treasury yields reach elevated levels ahead of the Federal Reserve decision.
