The government intends to use this tool to align bauxite output with the scheduled commissioning of 7-8 new alumina refineries requiring over 20 million tons of annual input, thereby forcing market rebalancing and accelerating downstream integration. The success of this high-stakes strategy hinges on mitigating its inherent risks: eroded investor confidence from regulatory volatility and industry consolidation that could reduce market participants by 30-40%, potentially undermining the capital investment required for a globally competitive downstream industry.

【SMM Analysis】 The European Union’s Carbon Border Adjustment Mechanism (CBAM) is a policy introduced to prevent carbon leakage and ensure fair competition by regulating the import of carbon-intensive goods into the EU.

The CBAM mechanism and export restrictions may become one of the key concerns in international aluminum trading and significantly affect the flow of aluminum raw materials and aluminum products.

[SMM Cast Aluminum Alloy Morning Comment: Aluminum Scarcity Difficult to Ease, Silicon Metal Sentiment Cools, ADC12 Holds Up Well] Overall, the supply-demand imbalance in raw materials persists, with enterprises facing significant procurement and cost pressures, coupled with steady and improving demand, providing upward momentum for prices.
