Iron Ore Price Surge to Two-Week High on China's Policy Support and Supply Shifts
Iron ore prices reached their highest level in nearly two weeks on September 22, 2025, with Australia’s benchmark 62% Fe fines edging up to $106.35/ton (CFR China). This capped a 3.45% gain for the month, bringing year-to-date advances to 5.7% amid supportive policy signals from Beijing and tightening supply conditions. The rally reflects renewed optimism in China’s steel-intensive sectors, though market participants caution that demand sustainability remains uncertain.
Policy Drivers Behind the Rally
China’s State Council and the People’s Bank of China (PBOC) have intensified efforts to stabilize economic growth through targeted monetary easing and sector-specific support. The PBOC’s recent 50-basis-point reserve requirement ratio (RRR) cut injected approximately ¥1 trillion ($140 billion) into the financial system, lowering borrowing costs for steel mills and infrastructure developers. Additionally, the Ministry of Industry and Information Technology (MIIT) released a two-year steel industry plan emphasizing price stability and secured iron ore supply chains, directly boosting market confidence. These measures align with China’s broader “anti-overcapacity” campaign, which prioritizes industrial upgrading over volume expansion, inadvertently supporting higher-value steel production and iron ore demand.
Supply-Demand Dynamics Tighten
On the supply side, global iron ore shipments surged 8.2 million tons week-on-week to 35.7 million tons, driven by increased exports from Australia (+2.6 million tons) and Brazil (+3.9 million tons). However, arrivals at China’s ports declined by 857,000 tons, indicating robust domestic consumption. Steel mill operations accelerated, with daily hot metal output rising to 2.41 million tons as producers ramped up production ahead of the October National Day holiday. Inventories of construction steel (e.g., rebar) continued declining atypically for the season, while port stockpiles fell to 138 million tons, reinforcing perceptions of a supply crunch.
Market Sentiment and Steel Sector Performance
Steel prices mirrored iron ore’s strength, with rebar gaining 0.56% and hot-rolled coil rising 0.39% on September 22. This uptick was fueled by improved demand from automotive and appliance manufacturing, alongside infrastructure projects funded by China’s ¥735 billion ($100 billion) stimulus package for major engineering initiatives. The Caixin/S&P Global Manufacturing PMI hit 51.8 in June—the fastest growth since May 2021—further bolstering sentiment. However, the official manufacturing PMI remained contractionary at 49.5, highlighting lingering vulnerabilities in traditional industrial sectors.
Global Trade and Future Risks
Internationally, warming China-U.S. trade relations provided tailwinds. High-level meetings between U.S. Treasury Secretary Scott Bessent and China’s top economic official in Switzerland eased fears of escalating tariffs, though average duties on Chinese goods remain at 39.3%. For iron ore, this reduces the risk of supply chain disruptions and supports stable import volumes. However, analysts warn that China’s property sector—which accounts for ~40% of steel demand—remains weak, with new construction starts down 29.6% year-on-year. If post-holiday demand falters or global shipments rebound sharply, prices could face downward pressure.
Outlook for Q4 2025
The iron ore price surge September 2025 trend will likely persist in the near term, supported by:
Pre-holiday restocking: Mills building inventories ahead of October’s week-long shutdown.
Policy momentum: Additional stimulus expected after China’s Third Plenum (July 15–18).
Supply constraints: Port drawdowns and delayed shipments from Brazil due to logistical delays.
Green transition demand: Steel required for renewable energy and EV infrastructure (e.g., silicon steel for motors).
Nevertheless, prices above $105/ton may prove unsustainable if construction activity fails to rebound or global recession risks intensify. Traders should monitor China’s property policy adjustments and iron ore shipment levels from Australia/Brazil for directional cues.
