Copper Market Insights: Forecast Adjustments and Tariff Implications

Copper prices experienced a pullback from a three-week high on Wednesday, influenced by U.S. inflation data that heightened speculation about potential Federal Reserve rate increases this month. Additionally, news of a preliminary agreement to prevent a strike at BHP’s Escondida, recognized as the world’s largest copper mine, contributed to a decreased supply premium on copper prices.

On the Comex market, December copper trading ended at $6.6695 per pound (approximately $14,704 per tonne), marking a 0.8% decrease after earlier reaching $6.7890. Notably, the most-active contract peaked at a record settlement of $6.89 on September 9, just before a report regarding a stalled White House tariff plan triggered a decline of more than 5% in prices.

In London, three-month copper prices reached a high of $14,700 per tonne before settling at $14,532 early in the afternoon. Cash copper recorded a remarkable settlement at $14,822 on Monday, followed by $14,741 on Tuesday, while the London Metal Exchange (LME) inventories have decreased for seven consecutive sessions, now totaling 229,650 tonnes.

The recent uptick in U.S. consumer prices, particularly driven by a surge in gasoline costs, has altered market expectations. According to the CME’s FedWatch tool, the probability of a quarter-point increase at the Fed's upcoming late-October meeting surged to around 44%, doubling the estimate from the day before. Furthermore, New York Fed President John Williams remarked that there's a strong likelihood of one additional rate hike within the year.

Supply Dynamics at Escondida

Reports indicate that the supervisors' union at Escondida has reached a preliminary agreement with the company, a deal that was subjected to a vote on Wednesday morning. A union leader described the agreement as “virtually done,” reflecting a significant development in reducing labor-related supply risks. Meanwhile, unions at Antofagasta’s Centinela resumed discussions after a week-long strike, while operations at Codelco’s El Teniente remain suspended following a tragic landslide incident.

Forecasts for copper prices in 2026 have seen revisions, indicating an optimistic outlook among industry analysts. With the metal averaging $13,471 per tonne year-to-date, expectations have risen for future prices. Macquarie forecasts an average of $13,573 for this year, while BMO Capital Markets anticipates $13,619, and BMI, a unit of Fitch Solutions, has set its target at $13,500, up from earlier projections of $12,700 made in July. The variances largely stem from differing assessments of the copper surplus sitting in the U.S., estimated between 1.5 to 2 million tonnes.

Market Sentiment: Copper Price Predictions

Macquarie's outlook, previously characterized by skepticism regarding price rallies, shows a significant shift. The bank has increased its price forecast for 2027 by 14% to $12,750, while raising its cycle low projection to $12,000 for Q4 of 2024. Despite these increases, the bank's report titled "The great copper gamble" highlights a disconnection between price levels and underlying fundamentals, indicating potential volatility based on the outcomes of tariff policies.

According to Macquarie, a surplus of 223,000 tonnes is expected this year, contrasted with a disruption allowance of 531,000 tonnes. The outlook anticipates annual surpluses exceeding 700,000 tonnes starting from 2027, driven mainly by a 4.9% increase in mine supply for next year. Key sites slated for ramp-up include Collahuasi, Grasberg, Kamoa-Kakula, and Centinela, in addition to expected improvements at Tia Maria and Cobre Panama by mid-2027.

In contrast, overall global demand growth is projected to slow down to 1.5% by 2027, particularly driven by an anticipated downturn in construction-related copper usage in China, which is set to decline by 9% per annum. Additionally, air conditioning manufacturers are reportedly exploring aluminum as a substitute for copper.

A broader look at inventory levels reflects a shift, with visible stocks increasing by 300,000 tonnes this year in the U.S., while global figures outside of the U.S. are down by 168,000 tonnes. Macquarie indicates that market sentiment won't shift until there is a tangible increase in LME and Shanghai inventories, either triggered by a quick tariff announcement or a gradual realization of forecasted surpluses.

Tariff Scenarios and Supply Impact

Macquarie's analysis includes four potential tariff scenarios, ranging from no action taken to a definitive decision against imposing tariffs. It notes that if tariffs are scrapped, there could be a drastic price collapse, potentially impacting LME pricing and leading to a reversal of the inventory balance with surplus U.S. stocks returning to LME facilities in the U.S. and Asia.

On the other hand, a tariff implemented six to eight weeks ahead of its effective date could draw additional metal into the U.S. market, subsequently tightening global supply. There's also speculation around possible inclusion of a scrap export ban, which could remove around 600,000 tonnes of contained copper annually from the global market.

Diverging Views on Market Dynamics

BMO Capital Markets presents a more bullish forecast compared to Macquarie. The bank's recent quarterly price assessment increases its long-term copper price prediction by 47% to $16,000 per tonne in real terms by 2030, with projected prices of $14,675 for 2027 and $16,000 for 2028. BMO's analysis emphasizes a balance in market dynamics, predicting an 83,000-tonne surplus in the current year followed by modest deficits starting in 2027.

Central to BMO's argument is the interpretation of the U.S. copper hoard, estimated to be close to 2 million tonnes, which the bank argues represents a redistribution of inventory rather than an absolute build. The research suggests that a simultaneous bid for copper from China could have resulted in significantly higher prices, indicating that future demand from Beijing could weigh heavily on market dynamics.

BMI finds itself in a middle-ground position, still viewing current price levels as somewhat overstretched compared to fundamentals and projecting the market in a 43,000-tonne surplus this year. Nonetheless, it has decreased its 2026 mine supply growth forecast due to a projected decline in Chilean output.

Investment Implications and Market Trends

The diminishing price spread has impacted U.S. stockpiling. As of now, Comex October copper trades below LME cash prices. Data analyses have shown a recent premium shift from an earlier 17-cent Comex premium in June to an 85-point LME premium today. The shortage of available metal outside the U.S. has driven European copper producers to offer record premiums for anticipated 2027 supplies.

Despite fluctuations in metal prices, some analysts are even predicting significant long-term price hikes. Deutsche Bank, for example, posits that, with countries including China continuing to stockpile strategically, copper may become increasingly scarce and potentially lead to prices around $10 per pound by Q2 2027, which would represent a substantial increase based on current levels.

As the copper market faces complexities regarding supply, demand, tariff implications, and geopolitical factors, stakeholders must navigate carefully through these evolving scenarios to gauge opportunities and risks effectively. The interplay between fresh supply dynamics, anticipated demand from major consumers, and the potential for regulatory changes will ultimately dictate the copper market landscape in the coming years.
