China Steel Output Rebounds Month-over-Month; Sharp Drop in Australian Freight Rates Benefits Aussie Miners

Overview

This J.P. Morgan channel-tracking report highlights updated high-frequency data on China's steel industry and shifts in the iron ore shipping market. Key findings indicate that China's crude steel production has recently shown signs of month-over-month recovery, while the iron ore shipping market has undergone significant changes—most notably, a sharp decline in Australian-to-China freight rates—which has reshaped the cost-competitiveness landscape among different producing regions. Based on these developments, the report revises its relative outlook on major iron ore-exposed equities across Europe, the Middle East, and Africa (EMEA), favoring Australian miners while remaining cautious toward those dependent on Brazilian and South African shipping routes.

Core views

Demand and Supply Sides: China's steel production activity has recently picked up. Data show that during the 10 days ending June 10, China's average daily crude steel output annualized at 1.018 billion tons, up 4% month-over-month and 2% year-over-year. Although the 30-day rolling production growth is only marginally positive at 1% YoY, China's reported steel output has remained near the lower end of its five-year range since May, demonstrating resilience. On the export front, May's annualized steel exports reached 122 million tons, near the upper end of historical averages, with cumulative exports of 45 million tons in the first five months—about 10% of total production. Costs and Logistics: The most notable development this week was the steep decline in bulk shipping costs. Freight rates from all major origins—Australia, Brazil, and South Africa—to China fell week-over-week. Australian-to-China rates plunged 22% ($3 per ton) to $10.9 per ton, while Brazilian and South African rates also dropped by 3%. This shift directly impacts FOB pricing calculations, implying an Australian FOB iron ore price of around $90 per ton—up 4% since the onset of the U.S.-Iran conflict in late February. However, it's worth noting that Brazilian and South African iron ore shipping rates still exceed pre-conflict levels by over 50%, which continues to favor Australian producers competitively. Profits and Inventories: Despite the rebound in production, Chinese steel mills have continued to widen losses in recent weeks due to rising coking coal prices. As for inventories, as of the week ending June 12, total Chinese steel stockpiles remained flat month-over-month but were up 7% year-over-year—consistent with seasonal trends. Port-based iron ore inventories stood at approximately 160 million tons, near historic highs but down 7 million tons from their March peak.

Analysis framework

The report employs a typical methodology combining high-frequency data tracking with relative value analysis. First, it monitors daily crude steel production figures released by the China Iron and Steel Association (CISA) to gauge short-term supply-and-demand marginal changes. Next, it delves into key cost variables—iron ore shipping rates—breaking them down by route (Australia, Brazil, South Africa) to derive FOB price competitiveness for each origin. Finally, macro-industry data are mapped onto specific listed companies, assessing how sensitive each miner is to varying freight rates along different routes, thereby gauging pressure on profit margins and assigning differentiated stock ratings. This approach underscores the decisive role of logistics cost differentials in determining upstream resource firms' profitability within commodity cycles.

Methodology notes

• Industry/Supply Chain Analysis FrameworkUpstream–Midstream–Downstream Transmission

  Shipping rates, as midstream logistics costs, directly affect upstream mine FOB net returns and downstream steel mill landed costs.

  By analyzing freight rate fluctuations, the report infers their impact on actual selling prices (FOB) across various mining origins, enabling identification of which miners benefit or suffer from rate volatility—highlighting logistics costs' pivotal role in profit distribution throughout the supply chain.

• Company Fundamentals and Financial Framework

  High-Frequency Channel Data Verification (Channel Checking)

  Utilizing daily or decadal data on production, inventory, freight rates, etc., replaces lagging financial reports, providing real-time insights into marginal changes in industry conditions and offering more timely guidance for short-term trading decisions.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• BHP

  Beneficiary, with primary assets in Australia benefiting from sharply lower Australian freight rates

  Strengths

  Lower Australian main-route freight costs enhance competitiveness; the report also overweighted its Australian-listed shares

  Comparison

  Compared to miners reliant on Brazilian routes, BHP enjoys a cost advantage

  Risks

  Global steel demand falls short of expectations

• Rio Tinto

  Relatively Benefited, with primary assets in Australia

  Strengths

  Lower Australian main-route freight costs; the report overweighted Rio Tinto Limited

  Comparison

  More favored than its London-listed shares, which received a neutral rating

  Risks

  Fluctuations in iron ore prices

• Anglo American

  Affected, with substantial exposure in Brazil and South Africa, squeezed by high freight costs

  Weaknesses

  High freight rates on Brazilian and South African routes continue to weigh on profit margins

  Comparison

  At a disadvantage compared to Australian miners

  Risks

  Persistently high freight rates and geopolitical risks

• Kumba Iron Ore

  Affected, with primary assets in South Africa, pressured by high freight costs

  Weaknesses

  South African freight rates remain 50% above pre-conflict levels, limiting profit margins

  Comparison

  At a disadvantage compared to Australian miners

  Risks

  South African infrastructure bottlenecks and freight rate volatility

Key data

• China's 10-Day Average Crude Steel Production (Annualized)1.018 billion tonsUp 4% month-over-month, 2% year-over-year
• Australian-to-China Bulk Freight Rate$10.9 per tonDown 22% week-over-week (-$3 per ton)
• Implied Australian FOB Iron Ore Price$90 per tonUp 4% since late February
• Brazilian/South African-to-China Freight Rate ChangesDown 3% week-over-weekStill more than 50% above pre-conflict levels
• Chinese Port-Based Iron Ore InventoryApproximately 160 million tonsDown 7 million tons from March peak
• May's Annualized Chinese Steel Export Rate122 million tonsNear the upper end of historical averages

Impact & implications

The report concludes that structural differentiation in shipping rates gives Australian iron ore producers a stronger competitive position, thanks to significantly reduced freight costs and lower absolute rates. Conversely, miners reliant on Brazilian and South African routes—such as Anglo American and Kumba Iron Ore—face greater margin pressures due to persistently high freight rates. Accordingly, the report favors overweighting Australian-listed mining giants while underweighting African and diversified miners burdened by elevated freight costs. For China's steel sector, although production shows month-over-month improvement, high raw material costs (coking coal) and weak profit margins constrain steelmakers' expansion ambitions, leaving the pace of inventory destocking yet to be seen.

Risks

• China's steel demand recovery falls short of expectations
• Iron ore shipping rates rebound
• Continued increases in raw material prices like coking coal squeeze steel mill profits
• Geopolitical conflicts disrupt Brazilian and South African supply chains

What to watch

• Sustainability of China's daily crude steel production trend
• Trends in Brazilian and South African-to-China shipping rates
• Progress in repairing steel mill profit margins
• Rate of destocking port-based iron ore inventories
