Benchmark three-month copper on the London Metal Exchange (LME) rose 0.29% to $13,661 a metric ton on Tuesday, driven by persistent concerns over supply-side tightness and strong purchasing activity from China.
The modest gain follows a broader rally in industrial metals, with the benchmark contract climbing 2.1% to $13,437 a metric ton earlier in the week.
That surge was fueled by growing market confidence in demand fundamentals, even as traders remain cautious ahead of the upcoming release of US consumer price index (CPI) data.
Supply constraints continue to underpin prices, with tight stock levels limiting downside risk.
Chinese buyers have remained active, providing a floor for the metal despite broader macroeconomic uncertainties.
The interplay between structural supply deficits and demand resilience has kept copper near multi-month highs.
