The South American steel industry stands at a crossroads in 2025, grappling with production declines, shifting demand dynamics, and evolving trade landscapes while positioning itself as a key player in the global transition to green steel. As regional economies face headwinds of 2.4% GDP growth—below the global average—steel producers are adapting strategies to leverage competitive advantages in high-quality iron ore and emerging sustainable mining initiatives.

Crude steel production across South America has experienced a notable contraction in 2025. According to the World Steel Association, the region produced 3.6 million tonnes (mt) in August 2025, marking a 5.0% year-on-year decline. For the full year, Latin American Steel Association (Alacero) forecasts a 2.5% drop in crude steel output to 55.39 mt, with finished steel production expected to fall 3.5% to approximately 50 mt. Brazil, the region’s industrial powerhouse, saw its August crude steel production decline by 4.6% year-on-year to 2.9 mt, though monthly output rose 6.1% in October as mills adjusted to market conditions.

This downward trend is attributed to a confluence of factors: high domestic interest rates, persistent inflation, and weakened demand from key end-use sectors like construction and automotive. Long products used in civil works and flat products for automotive manufacturing fell by 5.5% and 7.3% respectively in Brazil’s domestic market during October. However, counterbalancing these challenges is Brazil’s ongoing investment in iron ore mining expansion, exemplified by Vale’s "Novo Carajás" program—a $14 billion initiative to boost iron ore产能 to 200 mt annually by 2030, with a focus on low-carbon production technologies.

A defining feature of South America’s 2025 steel market is the divergence between stagnant domestic demand and robust export growth. In Brazil, October domestic sales dropped 6.5% year-on-year to 1.81 mt, while overseas shipments surged 28% to 907,000 tonnes—led by a 29% increase in semi-finished products. Year-to-date, Brazilian steel exports have risen 4.6% to 8.74 mt, demonstrating resilience despite new U.S. tariffs on steel and aluminum imports.

The import landscape tells a more nuanced story. Total steel imports in Brazil fell 21.4% in October, yet special steel arrivals more than doubled—from 34,500 to 77,400 tonnes—highlighting unmet demand for high-value steel products in sectors like machinery and renewable energy. This gap presents opportunities for regional producers to invest in product diversification and capture premium markets.

South America’s steel sector is increasingly aligning with global decarbonization goals. Vale’s Novo Carajás project emphasizes dry processing technology and尾矿再利用—such as the Jirau project, which will produce 6 mt of iron ore annually from tailings—to reduce carbon footprints. By focusing on sustainable mining practices and green steel feedstocks, Brazil aims to position itself as a leader in the global low-carbon steel market, leveraging its abundant reserves of high-grade iron ore essential for electric arc furnace (EAF) production.

However, policy challenges persist. Alacero cites high tariff environments and unresolved geopolitical issues as external headwinds, while internal barriers include regulatory uncertainties around carbon pricing. To unlock growth, governments and industry stakeholders must collaborate on policy frameworks that incentivize green investments while enhancing regional trade integration.

As 2025 progresses, South America’s steel industry faces a dual mandate: addressing immediate demand softness and laying the groundwork for sustainable growth. Producers are increasingly turning to exports, optimizing production processes, and investing in green steel technologies to remain competitive. For investors and traders, key opportunities lie in Brazil’s iron ore expansion, Argentina’s emerging EAF projects, and the region’s potential to supply low-carbon steel to global markets.

In conclusion, while short-term challenges of production declines and domestic demand weakness persist, South America’s steel sector is poised to capitalize on its natural resources and commitment to sustainability. By prioritizing high-quality iron ore production, export diversification, and green innovation, the region can navigate current headwinds and emerge as a vital player in the future of global steel.
