Los récords en volúmenes de comercio de acciones y metales de China indican un cambio estructural en los flujos de capital y la demanda industrial.

China's onshore equity market is undergoing a seismic transformation, driven by a confluence of technological innovation, policy tailwinds, and surging demand for green metals. In Q4 2025, the A-share market's annual trading turnover surpassed 405 trillion yuan ($57.6 trillion), a historic milestone that underscores a structural shift in capital flows toward AI infrastructure and electrification-linked sectors. This surge is not merely a short-term rally but a reflection of deepening industrial demand and strategic state-led investments that position China as a global leader in the electro-industrial revolution. For investors, the implications are clear: an immediate overweight position in AI-linked tech stocks and electrification-driven metals is warranted.

The AI Infrastructure Rally: A Policy-Driven Tech Boom

The rebound in Chinese technology stocks, particularly in AI infrastructure, has been fueled by breakthroughs like DeepSeek's R1 reasoning model, which catalyzed a surge in demand for data and cloud services, semiconductors, and power-related technologies. Global investors are increasingly allocating capital to Chinese AI firms, betting on the country's ability to close the technological gap with the U.S. and capitalize on its policy-driven innovation ecosystem. According to a Bloomberg report, China's AI sector is now a magnet for foreign capital, with firms leveraging state-backed R&D and domestic market scale to achieve rapid commercialization.

This momentum is further reinforced by China's dominance in critical minerals such as gallium and germanium, which are indispensable for high-performance semiconductors and fiber-optic communication systems. With 98% and 60% of global gallium and germanium production, respectively, China's control over these resources gives it unparalleled leverage in the AI supply chain. As analysis shows, China's position in critical minerals provides strategic advantage in the global AI race. As AI data centers proliferate, demand for these metals-and the associated infrastructure-is set to explode. By 2030, AI data centers in China alone are projected to consume over 1,000 terawatt-hours of electricity annually, equivalent to Japan's total consumption.

Electrification and the Green Metals Gold Rush

China's electrification push is reshaping global metals markets, with copper, aluminium, and rare earths at the forefront. The country's 15th Five-Year Plan (2026–2030) prioritizes grid modernization, renewable energy integration, and EV production, all of which require massive inputs of copper. For instance, each electric vehicle uses up to four times more copper than a conventional car, while grid upgrades are expected to drive an additional 512 kilotonnes of copper demand for data centers by 2030.

Aluminium demand is also surging, driven by lightweighting in EVs and solar panel installations. However, production caps on primary aluminium-set at 45 million tonnes annually since 2017-mean that demand must be met through recycled materials and energy-efficient processes. This creates a compelling investment case for firms specializing in recycling technologies and sustainable production. Meanwhile, tin's role in high-end electronics and solar panel soldering is expanding, with innovations in tin-based perovskite solar cells poised to further boost demand.

The electrification boom is not limited to base metals. Chinese energy storage firms, including Contemporary Amperex Technology (CATL) and BYD, are dominating global lithium-ion battery markets, with shipments expected to jump 75% in 2025. The International Energy Agency forecasts global battery storage investment to rise 16% in 2025 to $66 billion, much of which will be captured by Chinese companies. This trend is mirrored in the EV sector, where Chinese brands have seen their EU market share grow eightfold from 2019 to 2023.

Aerospace and AI: A Synergistic Demand Catalyst

China's aerospace sector is another underappreciated driver of green metals demand. The integration of AI into aerospace manufacturing and operations is accelerating, with applications ranging from predictive maintenance to autonomous flight systems. This requires advanced materials like titanium and aluminum alloys, which are critical for lightweight, high-strength components. According to EnergyConnects analysis, AI is being deployed to optimize renewable energy systems for aerospace applications, such as solar-powered drones and hydrogen-fueled aircraft.

Moreover, Reuters analysis indicates China's "AI+ Energy" strategy aims to achieve deep integration of AI into the energy sector by 2027, with aerospace being a key beneficiary. This convergence of AI and aerospace is creating a virtuous cycle of demand for green metals, further entrenching China's leadership in the electro-industrial landscape.

Conclusion: A High-Conviction Investment Thesis

The data is unequivocal: China's record stock and metals trading volumes signal a structural shift in capital flows and industrial demand. The AI infrastructure rally, electrification-driven metals boom, and aerospace-AI synergy present a compelling case for an immediate overweight position in these sectors. Investors who act now will be well-positioned to capitalize on the next phase of China's electro-industrial revolution, where policy, technology, and resource dominance converge to create unparalleled growth opportunities.
