Benchmark three-month copper on the London Metal Exchange (LME) rose 0.60% to $13,953 a metric ton on Tuesday, extending a rally driven by tightening physical supply.
The advance marks a continuation of the upward momentum seen earlier in the week, as traders respond to declining inventories across key global hubs.
The price action is underpinned by synchronized drawdowns in stockpiles at both the LME and the Shanghai Futures Exchange.
These inventory reductions signal robust demand absorption or constrained supply flows, reinforcing the bullish case for the industrial metal.
Copper had already climbed to its highest level in more than a week on Monday, setting the stage for further gains as sentiment shifts regarding global demand dynamics.
In energy markets, crude oil prices steadied, reflecting a standoff between conflicting diplomatic statements from the United States and Iran.
