On June 15, Southern Copper rose 3.29% overnight, trading at $196.03/share, with turnover of $114,300. The copper sector strengthened broadly, with Freeport-McMoRan up 2.75%, Ero Copper up 4.46%, and Taseko Mines up 3.2%.

On the news front, multiple supply-side disruptions continue to tighten the global copper market. Peru declared an emergency decree amid its energy crisis, with major copper mines cutting approximately 20,000 tons of monthly capacity due to power rationing. Indonesia's Grasberg mine full restart has been delayed to early 2028, expected to reduce copper supply by over 100,000 tons. Goldman Sachs previously cut its global copper mine supply growth forecast by 350,000 tons, with institutions noting the supply-demand imbalance remains unresolved.

Meanwhile, COMEX July copper futures surged 2.71% on Friday to $6.445/lb, hitting a new high since June 4, with weekly gains of 2.67% marking the fifth weekly advance in six weeks. Optimism over a potential US-Iran ceasefire agreement and ongoing COMEX-LME price premiums driving copper shipments to the US further supported prices.
