Before we dive in, I’d like to take a step back and look at how the copper market has evolved over the past decade.

There’s little doubt that copper has entered a bull run since the back end of 2022. Prices have moved in a clear upward trend, underpinned by a growing consensus that the market is heading toward a structural supply deficit later this decade.

At the same time, demand expectations remain robust, driven by power infrastructure, the energy transition, digitalization, and electrification, alongside the reality that there are limited viable substitutes for copper.

Against this backdrop, we’ve also seen increasing participation from speculative investors. Arguably, this has contributed to the volatility and price spikes of the past few years, with markets at times running ahead of macro and fundamental realities.

However, as we moved into the latter part of last year and the first half of this year, something changed.

Copper broke decisively out of that long-term trend channel and has held above it, reaching new all-time highs. This suggests that new, more durable bullish drivers may now be at play, potentially reshaping the copper landscape.

Copper is now widely recognized as a critical mineral. We’re seeing the rise of strategic stockpiling, the impact of US tariffs distorting global trade flows, and a renewed wave of macro-driven investor interest as copper becomes increasingly viewed as a tactical material for the future.

 

1. Are Copper Prices Justified at Record Highs?

Copper has broken above its long-term trend channel and reached record highs. Are prices justified by fundamentals, or are they increasingly being driven by strategic and speculative factors?

  • Bullish
  • Copper is increasingly being treated as a strategic asset rather than a traditional industrial commodity.
  • Future supply deficits are becoming more important than current inventories.
  • Strategic stockpiling ahead of anticipated shortages is rational behaviour.
  • Electrification, AI, power infrastructure and energy transition demand continue to strengthen the long-term outlook.
  • Current prices may simply reflect a higher equilibrium price needed to incentivise future mine development.
  • Bearish
  • Prices may be running ahead of near-term physical fundamentals.
  • Speculative positioning and investor flows have amplified price moves.
  • Some demand expectations may already be priced in.
  • Historical commodity cycles suggest sharp corrections are still possible even within long-term bull markets.

 

Areas of Consensus

  • Copper's pricing framework has changed.
  • Strategic considerations now play a larger role than in previous cycles.
  • Long-term fundamentals remain constructive.

Key Takeaway

The panel broadly agreed that copper's valuation is increasingly being driven by future scarcity rather than current availability. While short-term corrections remain possible, the structural bull case remains intact.

 

2. The New Copper Market: Why Has Behaviour Changed?

What has been the most surprising aspect about copper’s price behaviour over the last year?

  • Bullish
  • Copper's emergence as an investment-grade asset has expanded the investor base.
  • Increased financial participation reflects growing recognition of copper's strategic importance.
  • Strong investor interest may support higher pricing through the cycle.
  • Bearish
  • Markets have become increasingly headline-driven.
  • Political events and policy announcements are creating extreme volatility.
  • Traditional fundamental signals have become less reliable.
  • Large price swings may discourage physical participation.

Areas of Consensus

  • Volatility has increased materially.
  • Geopolitical developments now influence copper more than at any point in recent memory.

Key Takeaway

Copper is no longer trading solely as an industrial metal. Financial and geopolitical influences are increasingly shaping market behaviour.

 

3. Impact of the Iran Conflict

Would a resolution of the Iran War materially change the copper outlook?

  • Bullish
  • A peaceful resolution would support global growth.
  • Improved economic sentiment would benefit copper demand.
  • Lower logistics costs and reduced supply chain disruption would support market efficiency.
  • Bearish
  • Continued conflict creates downside risks to growth.
  • Higher energy costs could weaken industrial activity.
  • Geopolitical uncertainty may suppress investment and manufacturing activity.

Areas of Consensus

  • Copper remains fundamentally linked to global growth.
  • Resolution would be supportive, though not transformative.

Key Takeaway

The panel viewed geopolitical risk primarily through the lens of economic growth rather than direct copper supply disruption.

 

4. US Section 232 Tariffs

What happens next with US refined copper tariffs under Section 232 ("requiring 25% of copper input materials (such as copper ores, concentrates, mattes, cathodes, and anodes) produced in the United States to be sold in the United States – starting at 25% in 2027, increasing to 30% in 2028 and 40% in 2029@). 

Please note, there is no legal timeline for the decision. The 30th of June is when Howard Lutnick will outline his recommendation to the US President, but he does not have a 90-day deadline and/or then 15-days to enact it). President Trump may just absorb that information. 

However, if we assume the most bullish scenario where we see 15% tariffs at the start of 2027, and then 30% in 2028, how would you expect the market to actually adjust in the period immediately after announcement?

  • Bullish
  • Continued delays would encourage ongoing copper inflows into the US.
  • Strategic stockpiling could continue.
  • Tightness outside the US may become more pronounced.
  • Scrap export restrictions could tighten global markets further.
  • Bearish
  • Tariffs could distort trade flows and reduce market efficiency.
  • Elevated regional premiums could create demand disruption.
  • Policy uncertainty continues to weigh on investment decisions.

Areas of Consensus

  • The outcome remains highly uncertain.
  • Markets have partially priced in tariff risks.

Key Takeaway

The uncertainty itself has become a market driver, with many participants viewing future scrap policy as potentially more important than tariffs themselves.

 

5. Supply Growth and Mining Opportunities

Where are the biggest opportunities for miners today?

  • Bullish
  • Higher copper prices significantly improve project economics.
  • Governments increasingly support critical mineral development.
  • Investors are once again rewarding growth rather than capital discipline alone.
  • New financing structures may help unlock projects.
  • Bearish
  • Permitting remains difficult.
  • Cost overruns and execution risks remain significant.
  • Ore grades continue to decline globally.
  • Many large-scale projects remain capital intensive and technically challenging.

Areas of Consensus

  • The industry needs more mine supply.
  • Higher prices improve the development outlook.

Key Takeaway

The opportunity exists, but execution remains the challenge. Higher prices alone do not guarantee new supply.

 

6. Sulfuric Acid and Operational Risks

How significant are sulfur and sulfuric acid disruptions?

  • Bullish
  • Higher sulfur costs raise marginal production costs.
  • Supply chain disruptions can constrain output in vulnerable regions.
  •  
  • Bearish
  • Producers have largely secured required supplies.
  • Smelter economics remain relatively strong.
  • Market impacts remain manageable.
  • Any disruption is likely temporary rather than structural.

Areas of Consensus
Sulfur is an operational challenge rather than a market-changing event.

Key Takeaway
The panel viewed sulfur-related issues as important operational risks but not a defining factor for long-term copper prices.
 

7. Concentrate Market Tightness

Will concentrate deficits persist?

  • Bullish
  • Mine supply growth remains insufficient.
  • Treatment charges continue to signal acute tightness.
  • Smelter capacity has expanded faster than available feedstock.
  • Competition for concentrate is intensifying globally.
  • Bearish
  • Eventually lower smelter utilisation rates will rebalance the market.
  • Future mine projects could ease pressure if developed successfully.

 

Areas of Consensus

The concentrate market remains extremely tight.

Key Takeaway

Concentrate availability remains one of the strongest fundamental arguments supporting higher copper prices.

 

8. AI and Copper Demand

What is most misunderstood about AI-related copper demand?

 

  • Bullish
  • Data centres have limited ability to substitute away from copper.
  • AI infrastructure has a very high willingness to pay.
  • Copper is increasingly linked to national security and technology leadership.
  • AI amplifies electricity demand growth.
  • Bearish
  • AI still represents a relatively small share of total copper demand.
  • Future demand projections remain uncertain.
  • Current investment levels may not continue indefinitely.

Areas of Consensus

  • AI is strategically important.
  • Electricity demand remains the larger story.

Key Takeaway

The significance of AI lies less in today's demand volumes and more in its ability to reinforce long-term electricity and infrastructure demand growth.

9. Long-Term Copper Investment Case

How should investors think about copper miners and long-term pricing assumptions?

  • Bullish
  • Long-term copper price assumptions are rising.
  • Electricity demand growth continues to accelerate.
  • Investors increasingly recognise structural supply constraints.
  • Critical mineral policies support long-term investment.
  • Bearish
  • Large-scale projects remain difficult to execute.
  • Higher prices may eventually trigger substitution and demand responses.
  • Capital intensity remains elevated.

Areas of Consensus

Long-term fundamentals remain supportive.

Key Takeaway

The investment case is increasingly based on supply scarcity rather than demand optimism alone.

 

10. Demand Destruction Risks

Should markets be worried about demand destruction?

  • Bullish
  • Chinese demand remains resilient despite record prices.
  • Power infrastructure, solar and grid investment continue to support consumption.
  • Strategic stockpiling is adding to apparent demand.
  • Bearish
  • Higher prices inevitably increase substitution risk.
  • Some demand themes may already be fully priced in.
  • Economic weakness could expose demand fragility.
 

Areas of Consensus

  • Demand destruction is a risk at sufficiently high prices.
  • Evidence remains limited today.

Key Takeaway

The market acknowledges the risk, but current demand trends remain surprisingly resilient

11. Above-Ground Stocks and Hidden Inventories

How much copper is truly available to the market?

  • Bullish
  • Much of the metal moved into the US is effectively unavailable to global consumers.
  • Regional fragmentation reduces effective inventory availability.
  • Strategic stockpiling is absorbing material.
  • Bearish
  • Total inventory levels remain relatively healthy.
  • Current forward curves do not indicate extreme physical tightness.
  • Inventories could return to market if incentives change.

Areas of Consensus

Inventory visibility has become increasingly difficult.

Key Takeaway

The debate is no longer how much copper exists, but how much copper is actually available to the marginal buyer.

 

12. What Matters Most for Copper Prices Going Forward?

What single factor should investors watch most closely?

 

  • Bullish
  • Chinese buying activity.
  • Mine supply growth.
  • Rising incentive prices for new projects.
  • Continued electrification and power demand growth.
  • AI-related infrastructure investment.
  • Tariff uncertainty.
  • Bearish
  • Slower global growth.
  • Dollar strength.
  • Geopolitical shocks.
  • Demand destruction at higher prices.

Areas of Consensus

  • Structural supply constraints remain the dominant long-term theme.
  • Macro factors will continue driving short-term volatility.

Key Takeaway

The long-term story remains fundamentally bullish, but the path higher is likely to be increasingly volatile.
