Latin American steel equities and the SLX steel ETF traded lower on September 28, 2026, amid ongoing uncertainty surrounding U.S.-Mexico trade negotiations. Current tensions center on the 50% Section 232 tariff on Mexican steel imports, which remains in effect despite efforts to lower the rate to 10%.
Why it matters
The stalemate over steel tariffs is suppressing regional equity valuations and creating volatility for companies reliant on U.S. export volumes. Markets are closely watching these negotiations for potential breakthroughs that could reshape cost structures for manufacturers and steel producers alike.
Gerdau and Ternium New York shares declined 1.44% and 1.61% respectively, while the SLX steel ETF fell 0.69% to US$104.08. These shifts occurred as the Brazilian real weakened 0.86% against the U.S. dollar.
The players
Gerdau
A major Brazilian steel producer with extensive operations in the Americas.
Ternium
A leading Latin American steel manufacturer heavily exposed to export markets.
CSN
A diversified Brazilian company operating in the steel, mining, and cement sectors.
The details
Ternium's market performance is directly linked to export levels to the United States, making it sensitive to restrictive trade policies. Meanwhile, currency fluctuations of the Brazilian real influence the valuation of Brazilian ADRs, adding another layer of complexity for firms operating across borders. Automakers are currently anticipating that Washington may offer a 15% duty framework for vehicles, a move that could serve as a bellwether for wider industrial trade policy.
Timeline

September 24, 2026: CSN shares dropped 3.51%.

Market Landscape
The current market environment is dominated by the enforcement of Section 232 tariffs on steel imports. The potential shift toward a 10% tariff rate would mark a significant departure from current protectionist levels currently impacting global steel sentiment.
Operators should prepare for sustained volatility in steel pricing and supply chains until a trade resolution is reached. Monitor trade policy announcements closely, as any shift to a 10% duty could change procurement costs and margin projections for the coming quarter.
The takeaway
The dependence of Latin American steel valuations on U.S. trade policy remains a critical risk factor for regional industrial operations. Managers should hedge against supply cost fluctuations and maintain liquidity until clearer signals emerge regarding the potential tariff reduction.
