Latin Steel Wrap: CSN Slides, Ternium Steady on China Fears
Key Facts
- SLX, the global steel-producer ETF, slipped 0.89% to US$105.48 as a proxy for investor appetite toward the sector.
- Brazilian flat-steel maker CSN dropped 1.98% to US$0.99 after its mining division missed earnings forecasts by a wide margin.
- Gerdau’s New York ADRs ended flat at US$4.96 with a 0.00% move, reflecting a wait-and-see stance on Brazilian construction demand.
- Ternium, the Mexico-centric producer, gained 0.26% to US$49.24, buoyed by its diversified footprint from Argentina to the United States.
- CSN Mineração reported first-quarter earnings of US$0.04 per share missing the US$0.1251 forecast, which triggered the broader sell-off in its parent.
- Latin American governments periodically review anti-dumping duties on Chinese steel to shield domestic mills from what they allege are below-cost imports.
Today’s Focus
Latin American steel proxies painted a mixed picture on the first day of August. The SLX ETF, a global basket that includes heavyweights Gerdau, CSN and Ternium, eased 0.89% to US$105.48. The move primarily reflected a sharp 1.98% drop in CSN’s New York shares to US$0.99 after its mining arm, CSN Mineração, posted quarterly earnings per share of just US$0.04—a stark miss against the US$0.1251 consensus. Revenue of US$3.7 billion also fell short by 1.86%, underscoring the margin pressure exerted by freight costs and a volatile global market.
By contrast, Ternium’s American depositary shares rose 0.26% to US$49.24. The Luxembourg-headquartered group, which derives 55% of its sales from Mexico and a further 13% from Brazil via its 51.5% controlling stake in Usiminas, is viewed as a bellwether for North American manufacturing and auto sheets. Gerdau’s ADRs meanwhile stayed immobile at US$4.96, a flat 0.00% session, signalling that foreign investors are withholding conviction on Brazil’s long-steel demand for construction rebar and beams until fresh infrastructure data arrives.
The backdrop for all three names remains the relentless pressure of Chinese imports. Industry bodies in Brasília and Mexico City have repeatedly warned that Asian mills are offering flat and long steel at prices local producers cannot match. The Ternium Brasil Santa Cruz plant—a capital-heavy complex with its own private port and a 490 MW thermoelectric plant—has faced intensified import competition in plate products destined for shipbuilding and energy. Brazil’s policy response, a periodic review of anti-dumping duties on Chinese rebar and hot-rolled coil, has become a pivotal variable for Gerdau and CSN. Any sign of looser protection would remove a crucial safety net from beneath their domestic pricing power.
Auto and construction pipelines are the other side of the equation. Ternium and its Brazilian subsidiary Usiminas feed flat-steel sheet directly into automotive assembly lines from São Paulo to Monterrey, making Mexican vehicle exports to the United States a primary demand signal. Gerdau leans heavily on Brazil’s residential and infrastructure cycle, where any acceleration in public works could revive pricing for long products. For now, with CSN’s mining miss casting a shadow and Gerdau locked in neutral, the Latin American steel story is one of waiting for a clear tariff catalyst to counter the Chinese export wave.
What matters today. China remains the price-setter at the margin, and Latin America’s steel trade defence policy is the variable that determines whether domestic mills can restore profitability.

01 The session in one read
Latin American steel shares diverged sharply on Friday. The VanEck Steel ETF (SLX), a fund that tracks global steelmakers and holds Gerdau, CSN and Ternium among its top positions, fell 0.89% to US$105.48.
The session was dominated by a 1.98% slide in Companhia Siderúrgica Nacional (CSN) to US$0.99 after its mining affiliate missed quarterly profit forecasts, while Gerdau flatlined at US$4.96 and Ternium ticked 0.26% higher to US$49.24.

02 The board
The SLX ETF’s settlement at US$105.48 reflected modest but broad distaste for steel producer equities despite Ternium’s resilience. CSN’s New York shares, which trade under the SID ticker, dropped to US$0.99 as traders punished the company for CSN Mineração’s first-quarter earnings of US$0.04 per share, well short of the US$0.1251 expected.
Brazil’s Gerdau, a long-steel specialist whose ADRs are a pure-play proxy for construction, ended at US$4.96 with a 0.00% move. Ternium’s advance to US$49.24 highlighted a preference for the Mexico-focused name, where 55% of revenue originates and where auto-panel demand provides a steadier order book than Brazilian flats or longs.

03 What moved it
CSN’s slide was a direct response to a clear fundamental miss. CSN Mineração delivered revenue of US$3.7 billion, a 1.86% shortfall, and earnings per share that reached merely a third of the consensus estimate, dragging the parent company’s equity lower as freight costs and weak global steel markets ate into margins.
Gerdau’s static ADR price signalled a lack of conviction on Brazil’s construction pipeline. Ternium’s marginal gain reflected its extensive production footprint across six countries, including Mexico and the United States, which investors view as a natural hedge against any single nation’s tariff or demand shock.
04 The Latin American read
For Latin America, this was a session defined by the gravitational pull of Chinese excess capacity. Local producers Gerdau, CSN and Usiminas have repeatedly warned that Asian flat and long steel is arriving at price points that undercut domestic mills, prompting Brazil to maintain an active schedule of anti-dumping investigations.
Ternium’s 51.5% ownership of Usiminas places the Mexican group at the centre of this fight: the Santa Cruz plant in Rio de Janeiro state produces plate for automotive, energy and shipbuilding customers, sectors acutely sensitive to the price of imported alternatives arriving through Brazil’s ports.
05 The names to watch
Gerdau is the purest Latin American construction proxy, since its long-steel product mix—rebar and structural beams—is tied directly to Brazilian housing and infrastructure spending cycles.
Ternium offers exposure to Mexico’s automotive supply chain and the group’s 15.4 million tons of annual crude steel capacity, making it sensitive to vehicle output and any White House trade moves on Mexican auto exports. CSN adds a mining twist: its equity now carries the double weight of global iron ore prices and imported-steel pressure on its flat-product margins.
06 The outlook
The path forward hinges on two countervailing forces. On one side, weak CSN earnings and persistent Chinese export volumes threaten to compress regional margins further; on the other, any tightening of Latin American tariffs—particularly Brazilian anti-dumping duties on rebar and hot-rolled coil—could trigger a rapid repricing of Gerdau, CSN and Usiminas shares. Investors should watch for vehicle production data from Mexico and any Brazilian government decree on steel import duties, as these remain the primary catalysts for the next move in the SLX ETF and its Latin American components.
07 What to watch
- Brazilian anti-dumping duties: Any announcement from Brasília on new or extended tariffs against Chinese rebar or hot-rolled coil would directly lift the pricing power of Gerdau and CSN.
- Mexican auto and appliance output: Monthly vehicle assembly figures serve as a real-time demand proxy for Ternium’s flat-steel volumes and its Usiminas subsidiary.
- Chinese steel export volumes: A sustained spike in cargoes bound for Latin American ports would signal that the global glut is intensifying, eroding the trade-defence umbrella.
- CSN Mineração cost trajectory: Freight and production cost trends in the next quarter will determine whether the mining arm can claw back from its US$0.04 per share earnings miss.
Frequently Asked Questions
What does the SLX ETF track?
It tracks a basket of global steel producers including Gerdau, CSN and Ternium, making it a proxy for sector sentiment rather than the physical steel price.
Why did CSN drop so sharply?
CSN’s fall was driven by its mining division CSN Mineração posting quarterly earnings of US$0.04 per share, a large miss against the US$0.1251 forecast.
How does Ternium give me exposure to Mexico?
Ternium generates 55% of its sales in Mexico, supplying flat steel to the auto and construction industries, and its New York-listed TX shares are the most liquid proxy.
Are Latin American tariffs stopping Chinese steel?
Brazil and Mexico periodically review and apply anti-dumping duties on Chinese imports, but cheap Asian steel continues to arrive, compressing margins for domestic mills.
