Copper futures trading on COMEX remained active on Tuesday, 23 September 2025, with estimated volume at 31,080 contracts, down slightly from Monday’s 31,174. Open interest totaled 224,953 contracts, a net decrease of 116 from the prior session, according to an Associated Press market update. Each COMEX copper contract represents 25,000 pounds and is quoted in dollars per pound, providing a liquid benchmark for industrial users and investors tracking global manufacturing sentiment. The latest figures indicate steady participation even as broader macro drivers—such as shifting interest‑rate expectations, currency fluctuations, and Chinese demand signals—continue to influence base‑metals risk appetite. While the AP report does not list settlement prices, the stable volumes and minimal changes in open interest suggest positioning remained relatively balanced into the close. Market participants typically watch these metrics alongside warehouse stocks and spreads on the London Metal Exchange to gauge near‑term tightness or surplus in refined copper. The data snapshot provides a day‑of reference point for traders and hedgers in the wider non‑ferrous complex.
