China's Steel Industry Under Pressure: Demand Slowdown Signals Structural Shift
China's steel sector faces significant challenges as demand shows clear signs of softening despite the traditional construction season. Recent market data reveals the ratio between steel rebar futures and iron ore prices has fallen to its lowest level since 2020, indicating severely compressed profit margins for steel producers. This market imbalance highlights the structural challenges facing China's steel industry amid broader economic transitions and the China and steel demand slowdown.
Key Market Indicators Showing Pressure
The steel rebar to iron ore price ratio reached its lowest point since 2020 according to Bloomberg data, serving as a widely watched gauge of the steel market's health. This ratio decline clearly signals narrowing margins for producers across the industry.
Mill profitability has been fluctuating at historically low levels, with analysts expecting this trend to continue. As Han Jing from SDIC Futures Co. noted, "The mills' profitability is now expected to fluctuate at a lower level," highlighting the ongoing challenges producers face.
Despite weak steel demand, iron ore prices have shown remarkable resilience, with Singapore iron ore futures reaching levels not seen since February 2025. This price divergence further exacerbates the profit squeeze for steel manufacturers.
Shanghai rebar contracts declined for four consecutive days as of September 11, 2025, heading toward the lowest levels since July, reflecting persistent demand weakness.
Why is Chinese Steel Demand Declining?
Property Market Crisis and Construction Slowdown
The prolonged downturn in China's real estate sector continues to be the primary driver behind weakening steel demand. With property development historically consuming approximately 55% of China's steel output, the sector's ongoing struggles have created a significant demand gap that other industries cannot fill.
The ratio weakness underscores how China's steel sector remains inextricably tied to its struggling property market and slowing construction activity, both major consumers of reinforcement bar (rebar). Though steel mill margins performed better than expected earlier in 2025 as cheaper raw materials helped push down costs, this advantage appears to be diminishing.
Real Estate Market Challenges
Property developers face continued liquidity constraints despite government efforts to stabilize the sector. New construction starts have declined significantly year-over-year, with real estate investment continuing its multi-year downtrend.
Unsold commercial housing inventory remains at concerning levels, creating a substantial oversupply situation that will take years to resolve even with favorable policy interventions.
Construction activity continues its multi-year downtrend, with little evidence of a meaningful recovery on the horizon despite seasonal patterns that typically boost steel consumption.
Government Policy Constraints
Beijing's strategic policies aimed at controlling production and emissions have added another layer of complexity to the steel market dynamics.
The government has maintained a zero growth mandate for steel output since 2021, limiting producers' ability to increase volumes even when demand conditions might otherwise support expansion.
Carbon emission reduction targets continue affecting production capacity, as steel manufacturers must balance output with increasingly stringent environmental compliance requirements.
Sector restructuring plans announced in early 2025 signal further consolidation ahead, potentially reducing fragmentation but also creating uncertainty for smaller producers.
Production discipline measures to address overcapacity remain in effect, constraining supply even as demand weakens.
Economic Rebalancing Effects
China's ongoing transition from an infrastructure-focused growth model to a more consumer-oriented economy has fundamentally altered the demand landscape for steel.
The shift away from steel-intensive infrastructure investments toward service sector expansion has reduced the steel intensity of economic growth. Even robust GDP numbers no longer translate to proportional increases in steel consumption.
Manufacturing growth has proven insufficient to offset the construction decline, despite efforts to stimulate industrial production through various policy measures.
Changing consumption patterns are reducing per-capita steel intensity as the economy matures, following patterns observed in other developed economies.
Service sector expansion is replacing traditional industrial growth, further diminishing steel's role in the broader economic picture.
What's Happening with Iron Ore Prices Despite Weak Steel Demand?
Supply Concerns Driving Price Increases
Despite softening steel demand, iron ore trends have shown remarkable resilience, creating a paradoxical market situation that further squeezes steel producers.
Dalian iron ore futures reached the highest levels since July 2025 due to supply worries from the Simandou mine in Guinea and the upcoming restocking season in China, which boosted market sentiment. These factors have supported prices despite weakening fundamentals in the steel sector.
Factors Supporting Iron Ore Prices
Simandou mine supply uncertainties in Guinea have created concerns about future iron ore availability. Despite being one of the world's largest untapped high-grade iron ore deposits, ongoing development challenges continue to delay consistent production.
Seasonal restocking demand in China traditionally supports iron ore prices during certain periods, regardless of immediate steel production needs.
Mills have limited ability to push down raw material costs, as noted by Han Jing from SDIC Futures Co.: "It's difficult for mills to push down the raw material prices."
Singapore iron ore futures have reached levels not seen since February 2025, highlighting the divergence between raw material costs and finished steel prices.
The Profitability Squeeze for Steel Mills
The divergence between raw material costs and finished steel prices has created a challenging operating environment for Chinese steel producers.
As Foshan Financial Holdings Futures Co Ltd. explained in an analyst note, "Weak demand for finished steel products has kept steel prices subdued, yet the incentive for mills to sustain production is strong with modest profit margins. Iron ore prices are projected to outperform finished steel products."
Mill Response Strategies
Despite narrowing margins, many producers maintain production levels, prioritizing market share and operational continuity over short-term profitability.
The limited ability to pass on higher input costs to end-users reflects weak demand fundamentals and intense competition among producers.
Mills are increasingly focused on production efficiency improvements to reduce costs wherever possible, including energy consumption optimization and labor productivity enhancements.
Export increases help offset domestic demand weakness, though this strategy faces growing resistance from international markets concerned about iron ore surplus outlook.
