Hello, this is Daily Stock, rapidly capturing and analyzing critical turning points in the global market.
Summary
Copper futures, widely known as 'Dr. Copper', have recently surged, emerging as a hot topic in global financial markets.
This is the combined result of inelastic demand driven by the power infrastructure and AI data center construction boom, alongside supply disruptions in major producing countries.
Amidst the tri-polar economic decoupling of the US, Europe, and Asia, copper prices reflect bottlenecks in specific high-tech industries rather than a broad-based boom in the real economy.
This analysis provides an in-depth look at the latest trends in copper prices and their macroeconomic implications.
Market Overview
As of intraday trading on August 17, 2026, international copper prices are battling near historic highs on the London Metal Exchange (LME) and the New York Commodity Exchange (COMEX).
On August 12, COMEX copper September futures hit an all-time high of $6.7140 per pound and are now attempting to consolidate around the $6.60 mark.
LME spot copper also remains highly tight, recording $14,545.00 per metric ton.
Behind this surge lies a rapid decline in global refined copper inventories and inventory shifts triggered by US tariff policies.

Conversely, the Nasdaq Fear & Greed Index remains in Greed (65), matching last week's Greed (64.4) level, proving robust enthusiasm centered on tech stocks.
Today's market data points to KOSPI at 6,977.94, KOSDAQ at 864.65, Nasdaq at 26,729.16, and USD/KRW at 1,418.50.
Financial Analysis
To understand the supply-demand structure of the copper market, let's contrast LME inventory trends with key regional premiums and production metrics.
Refined copper imports to the US have surged, rapidly draining copper stocks in LME warehouses.
| Indicator | Latest Value (As of mid-August 2026) | Month-on-Month Change | Key Drivers & Background |
|---|---|---|---|
| **COMEX Copper Futures (per lb)** | $6.60 (Provisional intraday) | +4.86% (vs. 1 month ago) | Focus on AI grid investments & US tariff concerns |
| **LME Copper Spot (per ton)** | $14,545.00 (Official LME spot) | Remains strong | Escalating physical tightness & widening backwardation |
| **LME Copper Inventories (tons)** | 204,975 tons | -14.0% (vs. end of July) | US refined copper import rush reaching a 12-year high |
| **Yangshan Copper Premium (per ton)** | $96 | -16.5% (vs. $115 last month) | Chinese cable makers substituting with aluminum due to high costs |
On the supply side, severe weather (heavy snow and high winds) in Chile, the world's largest producer, and Codelco's downward revision of its production targets have had a major impact.
Consequently, the market has begun pricing in a long-term structural deficit scenario.
Tri-polar decoupling among the US, Europe, and Asia is also accelerating.
The US, backed by a relatively resilient real economy and massive tech capital, is aggressively absorbing copper for its AI grid infrastructure.
In contrast, Europe's copper demand remains stagnant as its manufacturing sector slows, even as it mandates renewable energy transition policies.
In Asia, particularly China, manufacturers are responding to high raw material costs by adopting alternative technologies to cut costs, highlighting the starkly different approaches of the three regions.
Valuation
Historically, copper prices have shown a very strong positive correlation with global manufacturing PMIs (Purchasing Managers' Index).
However, current valuations appear overstretched relative to the actual strength of traditional economic growth.
Copper is currently trading more than 46% higher than it was 12 months ago, pushing the copper-to-aluminum price ratio to historical highs.
These lofty valuations are prompting down-stream manufacturers in regions like China to favor substitution, switching from copper to aluminum.

From the perspective of global liquidity and macro policies, price divergence in commodity markets is widening.
The decoupling of monetary policies among major central banks is intensifying, with the US Federal Reserve maintaining high rates for longer, the European Central Bank (ECB) cutting rates preemptively, and the Bank of Japan (BOJ) shifting toward gradual tightening.
This policy mismatch exacerbates exchange rate volatility, which in turn fuels global speculative demand for dollar-denominated commodities like copper.
Consequently, current prices reflect a complex valuation driven by monetary policy uncertainty and infrastructure bottlenecks rather than pure macroeconomic strength.
Expert & Institutional Analysis
While major global investment banks acknowledge the structural tightness in the copper market, they offer mixed outlooks on near-term overheating.
Goldman Sachs indicated that the copper deficit outside Asia could reach 640,000 tons, hinting at a potential upward revision of its year-end LME target from $13,735 per ton.
UBS also upgraded its copper outlook for the second half of 2026, highlighting the sustainability of power grid modernization.
On the other hand, JPMorgan analyzed that the recent spike in copper prices is driven more by policy uncertainties and artificial inventory shifts rather than a traditional 'broad-based economic recovery.'
Furthermore, many metals research analysts assess that this copper rally is unlikely to translate into a trickle-down effect for the broader manufacturing sector.
This is because copper usage in consumer goods, such as general retail and appliances, remains stagnant outside of specific high-tech infrastructure sectors.
Risk Factors
The most significant risk is a demand destruction scenario triggered by prolonged high prices.
Already, wire and cable manufacturers in China, the largest consumer, have begun substituting copper with aluminum for low-voltage cables.
Additionally, depending on whether the US White House grants tariff exemptions for refined copper, the arbitrage mechanism between the New York and London markets could break down, leading to a sharp correction.
Warnings are also emerging that if global manufacturing PMIs slow further, strong demand in specific sectors alone will not be enough to sustain copper's high valuation.
Geopolitical risks and maritime supply chain disruptions are also variables adding to price volatility.
Should geopolitical tensions in South America—a key copper exporting region—or maritime bottlenecks ease, there is an inherent risk of a shift toward a temporary oversupply.
Investment Perspective
Rather than serving as a transparent leading indicator for the global economy, current copper prices are creating an illusion shaped by 'supply constraints' and 'inelastic demand from AI infrastructure.'
Therefore, betting on a full recovery of global equity markets based solely on copper prices may be premature.
As long as the economic temperature gap between the US, Europe, and Asia persists in this decoupling phase, investors must closely monitor capital concentration within commodity markets.
While tight supply-demand dynamics will support prices in the short term, a staggered approach that accounts for tariff policy changes and substitution trends seems prudent to prepare for volatility.
Rather than mechanically applying the historical 'Dr. Copper' rule, which acted as a wind vane for the business cycle, a multi-dimensional perspective that encompasses supply chain restructuring and shifting tech trends is required.
Rather than being swept up in market greed, investors need the foresight to calmly verify the elasticity of actual demand.
Investor Checklist Q&A
Q1. Can copper still be trusted as a leading economic indicator?
Unlike in the past, specific demand from power grids and the AI sector, combined with supply disruptions, is distorting prices. Thus, it is difficult to use it as a broad leading economic indicator. We are in a period of a 'Dr. Copper illusion' where copper prices are hitting record highs even though the overall economy is not in a boom.
Q2. What is the real reason behind the recent sharp drop in copper inventories?
It is because US imports of refined copper hit a 12-year high (surpassing 200,000 tons in July), rapidly absorbing LME warehouse inventories. This was largely driven by traders moving preemptively to secure volume before US tariffs take effect.
Q3. How is Chinese manufacturing responding to rising copper prices?
Burdened by high copper prices, Chinese wire and cable manufacturers are increasingly substituting copper with aluminum. Consequently, signs of cooling demand are appearing, with the symbolic Yangshan copper import premium falling to the $96 per ton level.
Q4. What are the copper price forecasts from major global institutions?
Goldman Sachs projects the year-end LME copper price to reach $13,735 per ton, warning of a supply deficit. However, some institutions maintain a cautious stance, judging that average market prices have entered short-term overshooting territory.
Q5. What is the right strategy for individual investors to cope with copper volatility?
Investors should monitor backwardation in the futures market (where spot prices are higher than futures prices) and tariff decisions in real-time. For commodity ETFs or mining stocks, accumulating positions in stages as a portfolio hedge, rather than chasing short-term rallies, is a safer way to mitigate risk.
