Copper Fund Rises 0.70% as Freeport Gains 0.99% | Copper, Oct 28
Key Facts
- The copper-tracking CPER fund rose 0.70% to US$40.33 on Wednesday, October 28, while the broader copper-miners fund COPX added 0.20% to US$76.83.
- Freeport-McMoRan, a US-listed miner with large Peruvian and Indonesian mines, gained 0.99% to US$66.60; Southern Copper, the Peru- and Mexico-focused miner, slipped 0.27% to US$193.91.
- The US Federal Reserve (Fed) held rates at 3¾% to 4% with two of its twelve voters preferring a quarter-point rise; the dollar index fell 0.16% to 102.16.
- Copper is a bellwether for global factories and power grids, so US readers watch it as a signal for tariffs and for electric-vehicle and data-centre demand.
- Prediction markets: Polymarket, a prediction market, puts 21.5% on US Section 232 tariffs (national-security tariffs) on copper cable by 31 December 2026, as of 28 October 2026, 8:47 pm ET.
Today’s Focus
Copper edged up on Wednesday on a day when the US Federal Reserve, the US central bank, split over rates. The US-listed copper fund CPER, which tracks copper futures, rose 0.70% to US$40.33.
Miners were mixed. Freeport-McMoRan gained 0.99%, while Southern Copper, a major producer in Peru and Mexico, slipped 0.27%, and BHP, the Australian giant, fell 0.46%.
The Fed kept its target range at 3¾% to 4%, but two voters wanted a quarter-point rise. A weaker dollar, with the dollar index down 0.16%, makes metals priced in dollars cheaper for foreign buyers.
What matters today. Copper is Chile’s and Peru’s biggest export and a key input for US power grids and electric vehicles, so a steady price supports both producer currencies and American infrastructure costs.
01 The session in one read
Copper ended Wednesday modestly higher. CPER closed at US$40.33, up 0.70% from US$40.05, and COPX, a fund of copper-mining companies, rose 0.20%.
Fed policy was the day’s main macro event. The vote was 10 to 2, with Fed governor Lisa Cook and Cleveland Fed president Beth Hammack dissenting in favour of a rise, according to the Fed’s official statement.
China, the world’s largest copper buyer, had no major data on the economic calendar for 28 October, so the metal traded on the dollar and on US rate signals.
Copper rose less than 1%, and miner shares were split, so there was no strong signal either way. The weaker dollar helped, but the Fed’s hawkish dissent keeps US rates in focus.
The variable to watch is China’s demand data in the coming days, since the country takes roughly half of the world’s refined copper.
02 The board
The CPER fund tracks copper futures rather than the physical metal, so it is a directional proxy and not a perfect mirror of the cash price. It rose 0.70% on the day.
Freeport-McMoRan added 0.99% to US$66.60. Southern Copper, a major producer in Peru and Mexico, dipped 0.27% to US$193.91, and BHP lost 0.46% to US$82.22.

03 What moved it
The dollar index slipped 0.16% to 102.16, which usually supports dollar-priced metals, but a 0.7% gain is too small to name one driver.
The Fed’s decision added a twist. Holding rates is neutral for copper, but two dissenters wanting a rise signal that US borrowing costs may stay high, which can slow construction and manufacturing.
04 The Latin American read
Chile, the world’s largest copper producer, saw its stock index fall 0.82% on Wednesday, while its peso weakened about 0.3% to roughly 988 per dollar. Copper held steady, so the move was not metal-driven.
Peru, the second-largest producer, is home to Southern Copper’s mines and to Cerro Verde, a large mine run by Freeport-McMoRan. Southern Copper’s shares slipped 0.27% on the day.
Mexico’s Grupo México, which owns Southern Copper, rose 0.4% on the Mexican exchange.
05 The names to watch
Freeport-McMoRan is the cleanest US-listed play on copper, and it gained on the day.
For investors who want exposure without single-company risk, CPER tracks futures and COPX holds miners, but they can diverge, as they did slightly on Wednesday.
06 The outlook
Copper is likely to stay tied to the dollar and US rate expectations in the short term. A strong US growth reading would help demand but could also lift yields.
The next catalysts are China’s industrial data and any news on US tariffs, as prediction markets still see a one-in-five chance of Section 232 tariffs (national-security tariffs) on copper cable by the end of 2026.
What Prediction Markets Say
On Polymarket, a prediction market, traders put the chance that US Section 232 tariffs hit copper cable by 31 December 2026 at 21.5%, and by 31 December 2027 at 45.0%. About US$17,000 has been traded on this market, as of 28 October 2026, 8:47 pm ET.
Prices on prediction markets are bets, not polls or forecasts by officials.
Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.
07 What to watch
- US dollar: A further fall in the dollar index would support copper; a rebound would cap it.
- China demand data: Industrial output and grid-investment numbers set the tone for global demand.
- US tariffs: Any Section 232 announcement on copper products would move US prices.
- Peru and Chile output: Mine disruptions in either country would tighten supply.
Frequently Asked Questions
Does CPER track the spot copper price?
No. CPER tracks copper futures contracts, not the spot price of physical copper.
Why do US investors watch copper?
It is an input for power grids, electric vehicles and data centres, and a gauge of global industrial demand.
Which countries produce the most copper?
Chile is the world’s largest producer and Peru is the second-largest.
How did copper miners do on Wednesday?
Freeport-McMoRan rose 0.99%, Southern Copper fell 0.27% and BHP fell 0.46%.
