Copper Tracker Falls 2.3% as Fed Hike Bets Lift Dollar

The session in one read

Copper futures retreated on Monday, September 28, 2026, as a rising dollar and firmer US rate expectations weighed on metals across the board. The CPER tracker, which tracks copper futures rather than physical metal, settled at US$39.68, down 2.29%.

The sell-off was not isolated to copper; spot gold posted its lowest close since 4 August as Treasury yields rose and traders priced in another Federal Reserve rate hike in October. Rising oil prices added to the dollar’s appeal, further pressuring metals priced in the US currency.

The board

The copper-tracking fund CPER closed at US$39.68, a decline of 2.29% on the session. The fall in the futures proxy was the largest among the three names on the board.

Southern Copper, one of Latin America’s largest producers, slipped 0.63% to US$202.63. Freeport-McMoRan held up slightly better, down 0.48% at US$71.96, showing that equity holders absorbed the commodity drop with less alarm than futures traders.

What moved it

The primary driver was a rise in US Treasury yields, with the 10-year yield up about eight basis points to 5.24%, which strengthened the dollar and made copper more expensive for buyers using other currencies. Higher yields also reduce the relative appeal of commodities that pay no interest.

A rise in oil prices reinforced inflation concerns and supported the greenback, while markets bet the Federal Reserve, which raised rates on 16 September, would hike again in October. That macro combination overshadowed copper’s own supply-demand fundamentals on the day.

The Latin American read

Chile remains the world’s largest copper miner, producing 5.3 million metric tons in 2025, about 23% of global mine output. Peru ranks third with 2.7 million metric tons, just under 12%, behind the Democratic Republic of the Congo at 3.2 million, according to US Geological Survey estimates.

For both Andean economies, copper is the main export engine and a key source of fiscal revenue. A 2.29% drop in the futures tracker may not reshape budgets, but it feeds into currency and tax expectations if the dollar keeps strengthening. On Monday the Chilean peso weakened 0.4% to 965 per US dollar and the Peruvian sol 0.7% to 3.44 per US dollar.

The names to watch

Southern Copper, controlled by Grupo México, has large operations in Peru and Mexico. Its shares fell only 0.63% to US$202.63, suggesting investors saw limited damage from the futures decline.

Freeport-McMoRan, with major South American assets including Cerro Verde in Peru, slipped 0.48% to US$71.96. Codelco, Chile’s state-owned producer, is not exchange-listed but remains a benchmark for national output and policy direction.

The outlook

The near-term direction depends on US yields and the dollar. If the Federal Reserve keeps signalling tighter policy, copper may face further pressure even as physical demand from China’s grid investment and electric-vehicle sector stays firm.

What to watch

US Treasury yields: another rise would strengthen the dollar and could push copper lower despite solid physical demand

China grid spending: electricity network investment and EV production remain the key demand pillars for refined copper

Peru supply risks: any disruption in Peru’s 2.7 million metric tons of annual output would tighten the global balance quickly

Mining equities: producer shares falling less than the futures tracker suggests markets view the macro hit as temporary

Frequently Asked Questions
