FAQ: US Copper Cathode Premium Pricing

What exactly is a copper cathode premium?

The copper cathode premium represents the additional amount paid above the LME copper price for physical delivery of copper cathode to a specific location. This premium reflects regional supply-demand dynamics, logistics costs, import duties, and other market conditions specific to the delivery location. It essentially captures the "regional premium" for physical metal delivery.

How does the all-in price differ from the premium?

The all-in price combines the LME copper price with the regional premium, providing a total delivered price for copper cathode in the specified location. While the premium (MB-CU-0002) only captures the amount above the LME price, the all-in price (MB-CU-0309) represents the total cost including both components, giving a comprehensive view of the delivered cost.

Why standardize on US cents per pound as the unit?

The standardization on US cents per pound aligns with common trading practices in the North American market. This unit is the predominant measure used by US domestic traders, consumers, and producers, making it the most intuitive and practical choice for market participants in the region. The standardization eliminates the need for unit conversion when comparing the premium and all-in price.

How might these changes affect copper-dependent industries?

Industries such as wire and cable manufacturing, electrical equipment production, construction, and automotive manufacturing may benefit from:

• Clearer pricing references: Standardized units and quality specifications simplify contract negotiations
• More efficient procurement: Aligned benchmarks facilitate more accurate cost forecasting
• Reduced basis risk: Consistent specifications improve hedging effectiveness
• Enhanced transparency: Uniform terminology creates greater clarity in supply agreements

These improvements may be particularly valuable for electric vehicle manufacturers, where copper represents approximately 14% of battery production costs.

What is the significance of including both LME and ASTM specifications?

The dual specification approach serves several important purposes:

• Global integration: Acknowledges the international nature of copper production forecast
• Regional relevance: Recognizes North American market preferences (ASTM standards)
• Broader application: Makes the assessments relevant to a wider range of market participants
• Specification alignment: Creates consistency between the premium and all-in price assessments

This approach reflects the reality that copper cathodes meeting either standard trade actively in the US market, making a combined specification more representative of actual market activity.
