Latin America Steel Falls: SLX, Gerdau, Ternium Drop
Key Facts
- SLX steel ETF dropped 2.62% to US$106.11 as global rate expectations shifted against cyclical shares on Monday, September 14, 2026.
- Gerdau’s New York shares sank 5.05% to US$4.89 despite the company’s role as a major Brazilian long-steel supplier to construction.
- CSN’s US-listed shares fell hardest, down 7.09% to US$1.18, the steepest loss among the region’s big steel names tracked by The Rio Times.
- Ternium gave up 3.35% settling at US$55.96 as Mexican tariff protection failed to insulate the stock from the broader sell-off.
- Brazil keeps a 25% tariff on steel imports above quotas across 19 product categories until June 2027, shielding Gerdau, CSN and Usiminas from cheap Chinese supply.
- Mexico applies tariffs of 5% to 50% across 1,463 tariff lines, with steel lines set near 20%, a wall aimed at countries that have no trade agreement with Mexico.
Today’s Focus
Latin American steel equities slid on Monday, September 14, 2026 as rising oil prices and near-5% Treasury yields hardened expectations of another Federal Reserve rate hike, punishing construction-linked and auto-linked steel shares.
The VanEck Steel ETF, a proxy for global steel producers, fell 2.62% to US$106.11. Gerdau dropped 5.05% to US$4.89, CSN lost 7.09% to US$1.18, and Ternium declined 3.35% to US$55.96.
The sell-off came despite tariff walls in Brazil and Mexico that keep cheap Chinese steel from flooding regional markets. Brazil’s 25% quota tariff and five-year anti-dumping duties, alongside Mexico’s 5% to 50% regime, remain the main policy props under local mill margins.
Construction and infrastructure demand continues to support Gerdau, but Monday’s trade showed that investors will sell first and ask demand questions later when borrowing costs are expected to climb.
What matters today. Rate-hike fears overpowered tariff protection and steady construction demand, hitting Latin American steel shares across the board.
01 The session in one read
Latin American steel stocks tumbled on Monday, September 14, 2026 as a surge in oil prices and near-5% Treasury yields pushed markets to price in a near-certain Federal Reserve rate hike. The VanEck Steel ETF, a widely held proxy for global steel producers, fell 2.62% to US$106.11.
Brazilian and Mexican names led the decline. Gerdau dropped 5.05% to US$4.89, CSN lost 7.09% to US$1.18, and Ternium gave up 3.35% to US$55.96, leaving investors nursing losses despite tariff walls that keep Chinese imports at bay.
The direction of travel is clear. Steel equities are trading on the Federal Reserve’s next move, not on steel fundamentals. Brazilian and Mexican mills still enjoy real protection from Chinese dumping. That does not matter when global investors pull money from cyclicals. The variable to watch is the US 10-year Treasury yield. Another push toward 5% will pressure SLX and its Latin American components further, even if construction and auto orders hold steady.
02 The board
The price board told a grim story for the steel sector. CSN’s US-listed shares were the session’s worst performer, plunging 7.09% to US$1.18, while Gerdau’s drop of 5.05% to US$4.89 showed that even construction-linked long-steel demand could not protect it.
Ternium’s 3.35% fall to US$55.96 was smaller but confirmed that Mexican tariff protection offers no immunity from global rate repricing. SLX, the sector ETF that holds both Gerdau and Ternium, settled down 2.62% at US$106.11.

03 What moved it
The trigger was macro, not steel-specific. Oil surged after new attacks on a Saudi pipeline, and gold sank nearly 2% as yields on the 10-year Treasury approached 5%, making the Federal Reserve 90% likely to raise rates in market pricing.
Higher borrowing costs hit construction and auto demand expectations hard. Steel is a classic cyclical trade, so investors sold first and asked about order books later, even though Brazilian construction and infrastructure spending continues to support Gerdau’s rebar and beam sales.
04 The Latin American read
Brazil maintains a 25% tariff on steel imports that exceed quotas across 19 product categories, renewed in June 2026 and running through June 23, 2027. A wider 23-product list applied in the 2025 round. Five-year anti-dumping duties on Chinese cold-rolled, coated, galvanised and wire rod products reinforce that wall.
Mexico applies tariffs of 5% to 50% across 1,463 tariff lines, in force since January 1, 2026, and aimed at imports from countries with no free-trade agreement. Steel lines sit near the bottom of that range, around 20%, not at the 50% ceiling. Yet Monday proved that even these high trade walls cannot shield Ternium and Brazilian mills when global rate fears dominate.
05 The names to watch
Gerdau remains the clearest play on Brazilian construction and infrastructure, given its focus on long steel used in buildings and public works. CSN is more exposed to flat steel, where Chinese dumping pressure is most acute despite anti-dumping duties.
Ternium ties its fortunes to Mexican auto assembly, which consumes flat steel at high volumes. The VanEck Steel ETF offers foreign investors a single access point to all three names, though Monday’s 2.62% fall showed the downside of that diversification.
06 The outlook
The near-term path hinges on the US 10-year Treasury yield. If yields stay near 5%, steel shares will struggle even with firm construction orders and tariff protection, because the cost of financing buildings, cars and infrastructure rises sharply.
07 What to watch
- US 10-year Treasury yield: Another push toward 5% would raise financing costs for construction and autos, the two pillars of Latin American steel demand.
- Brazilian infrastructure tenders: New public works spending would lift Gerdau and CSN volumes, but Monday showed macro can override even good project news.
- Chinese steel export data: More cheap supply heading toward Latin America would test Brazil’s 25% tariff and Mexico’s 50% ceiling.
- Mexican auto production: Ternium’s flat-steel sales depend on North American vehicle assembly, which is sensitive to interest rates.
Frequently Asked Questions
