China's National Development and Reform Commission is preparing to mandate 30 million tonnes of steel capacity closures in the second half of 2026, targeting the construction steel sector. The policy is part of China's commitment to peak carbon emissions by 2030.
A 30-million-tonne reduction in steel production would reduce iron ore demand by approximately 45 million tonnes at average conversion rates. This would increase the seaborne surplus by roughly 3% of the global market.
The cuts would disproportionately affect rebar and other construction-grade steel, reinforcing the structural decline in Chinese steel consumption that has been underway since 2020. China's steel output peaked at 1.065 billion tonnes in 2020 and has been flat-to-declining since.
The policy implications for iron ore are bearish. With supply from major miners at record levels and Simandou adding new capacity, any demand reduction from China would push the market deeper into surplus.
If NDRC capacity cuts proceed, iron ore prices will face significant headwinds. Delay large-volume purchases until the policy is confirmed. The $90/t level becomes a realistic target if China cuts 30 million tonnes of steel capacity in H2 2026.
