Bold claim: China is reshaping its role in global metal markets by pushing steel exports higher while aluminium shipments slide. And this tension reveals the broader story of a country balancing overcapacity, domestic demand, and international trade dynamics. Here’s a clearer, beginner-friendly rewrite that preserves all essential details while expanding context where helpful.
China’s steel exports have surged this year as domestic demand softens, especially in property development, whereas aluminium exports have fallen as manufacturing and energy activity absorb more of the nation’s output. China remains the world’s top producer of both steel and aluminium, together accounting for more than half of global supply. To curb overcapacity, Beijing has adopted informal production ceilings that neither industry can ignore.
The steel side operates under an informal cap tied to the prior year’s output. If the previous year saw 1.005 billion metric tons, that becomes the ceiling. With 10 months’ production at 817.87 million tons, 2025 could dip below one billion tons for the first time since 2019. The weakness in property construction dampens domestic steel demand, leading mills to compensate by increasing exports.
According to customs data released Monday, steel product exports rose 6.7% year over year to 107.72 million tons in the first 11 months of the year. If December exports stay near the annual average, total steel shipments would land around 117 million tons, potentially a record high and surpassing the 112.39 million tons exported in 2015.
Export profitability remains attractive for steel producers because domestic prices have languished near five-year lows. For example, Shanghai rebar closed at 3,128 yuan per ton on a recent Monday, with prices moving little after a low of 3,012 yuan in early June. Chinese steel also remains competitively priced against international benchmarks; for instance, last week’s LME rebar contracts in Turkey settled around $560.50 per ton.
Remarkably, China has managed to boost steel exports despite several countries imposing tariffs to protect their own producers. A significant share of Chinese steel goes to other Asian countries with limited domestic production, where buying cheaper Chinese steel makes economic sense.
In contrast, aluminium trends have moved in the opposite direction. Refined aluminium and related products exported by China fell 9.2% year to date through November, totaling 5.59 million tons. The country’s aluminium production is expected to stay very close to its annual cap of 45 million tons, while rising demand from manufacturing and energy sectors leaves less metal available for export.
A notable consequence of reduced Chinese aluminium supply in global markets has been a run-up in benchmark prices. On December 5, the London price rose to $2,920 per ton—the highest since May 2022. The price has climbed about 27% from its low of $2,300 in early April 2025. This upturn has offered some relief to Western smelters that have faced stiff competition, particularly in Europe and Australia where energy costs have surged.
If Beijing continues to cap aluminium at 45 million tons annually, tighter global supplies could persist into 2026. The question now is whether China’s steel sector will follow aluminium’s path and tighten supply. Assuming a 1 billion ton annual steel cap, the key variable is domestic demand’s recovery pace. As long as construction remains weak, steel mills may keep exporting to sustain profitability or may gradually retire older furnaces to reduce capacity.
Bottom line: China’s steel export surge and aluminium export slump reflect divergent domestic demand trajectories and the ongoing effort to manage supply. The outcome will hinge on how quickly construction rebounds and how Beijing tweaks production ceilings for both sectors. What’s your take on how these dynamics will shape global steel and aluminium markets next year?
