Today’s Focus
Latin American steel equities split on Thursday, August 20, 2026, with Brazil’s Gerdau underperforming while Mexico’s Ternium edged higher, against a falling global steel benchmark. The SLX ETF dropped 1.78% to US$104.80, capturing the weight of an oversupplied global market.
Gerdau’s ADR slid 2.91% to US$4.33, a sharp reversal that exposed how tariff protection alone cannot offset sluggish domestic construction demand in Brazil. The company’s long-steel products, including rebar and beams, depend on a building cycle that remains fragile.
In contrast, CSN’s ADR rose 1.28% to US$0.8913, finding support from February’s anti-dumping duties on Chinese flat steel. Ternium advanced 0.39% to US$54.21, helped by Mexico’s nearshoring-driven industrial building and steady automotive orders under USMCA.
The day’s mixed tape underlines a regional divide: Mexican mills are riding a structural shift in North American supply chains, while Brazilian producers struggle to convert legal trade protection into sustained pricing power amid weak local demand.
What matters today. Investors are testing whether Latin American tariff barriers can withstand a global steel glut; Thursday showed the answer depends heavily on local demand, not just trade policy.
01 The session in one read
Thursday’s session exposed a clear fault line running through Latin American steel: Brazil’s construction-heavy producers fell while Mexico’s industrial supplier held its ground. Gerdau, the region’s long-steel bellwether, dropped 2.91% to US$4.33, underperforming a global sector that also weakened.
The broad SLX tracker fell 1.78% to US$104.80, but there was no single regional move. CSN’s ADR rose 1.28% to US$0.8913, and Ternium added 0.39% to US$54.21, as investors sorted companies by their exposure to real local demand rather than headline tariff support.
Gerdau’s 2.91% slide to US$4.33, against a 1.78% drop in SLX, signals that the market is no longer rewarding Brazilian steel producers simply for having anti-dumping protection. Chinese steel exports are in fact down 4.4% so far this year, and sheet and plate down 9.9% — the pressure is a high plateau rather than a rising flood. The trade is rotating toward names with tangible demand tailwinds, such as Ternium’s nearshoring story in Mexico. The variable to watch is Brazilian construction activity.
02 The board
The price board tells a story of diverging fortunes within one sector. Gerdau’s slide to US$4.33 stands out as the session’s weakest Latin name, a clear sign that its North American strength could not offset Brazilian weakness. The company’s Q2 results showed adjusted EBITDA of R$3.4 billion (about US$655 million), up 33.9% and North America-driven, yet traders sold the ADR hard.
CSN at US$0.8913 and Ternium at US$54.21 both closed higher, with Ternium’s move more modest but still positive against a falling global benchmark. That relative strength points to Mexico’s auto and nearshoring demand, and to CSN’s flat-steel tariff shield in Brazil, as the factors keeping buyers engaged.

03 What moved it
Cheap Chinese steel remains the dominant force compressing mill margins across the region, even as export volumes fall 4.4% year on year. Brazil and Mexico have imposed new anti-dumping duties, but those legal barriers are struggling to overcome the sheer volume of Asian exports that keeps domestic prices under pressure.
For Gerdau, the swing factor was construction. The stock has repeatedly rallied on tariff headlines only to give back those gains when investors refocus on a slow Brazilian building pipeline. Thursday’s 2.91% drop fits that pattern precisely.
Ternium’s resilience reflects a different demand base. Mexico’s industrial and logistics construction, fuelled by nearshoring, supports orders for flat and long steel even while Chinese slab undercuts spot prices. That structural demand is giving Ternium more cushion than its Brazilian peers.
04 The Latin American read
For foreign investors, Thursday was a reminder that Brazilian steel is not one trade but two: tariff protection and domestic macro. Gerdau owns the construction lever, CSN the flat-steel tariff lever, and Usiminas the auto lever. Only CSN’s lever worked today.
Mexico’s Ternium is benefiting from a strategic relocation of manufacturing closer to the United States. This nearshoring wave is generating real orders for factory frames, warehouses, and automotive supply chains, giving Ternium a demand story independent of Chinese price wars.
05 The names to watch
Gerdau is the name most exposed to the weak link in the chain: Brazilian construction. Until building orders recover, its strong North American performance will keep fighting a losing battle with sentiment around Brazilian demand.
CSN offers the purest play on flat-steel anti-dumping policy in Brazil. Its low absolute dollar price, at US$0.8913, makes it a high-beta instrument for anyone betting on tariff enforcement.
Ternium is the structural long for investors who believe North American supply chains will keep relocating to Mexico. Its auto exposure under USMCA adds a layer of contractual demand that Brazilian mills lack.
SLX at US$104.80 remains the global barometer. If it keeps falling, even tariff-protected Latin names will struggle to hold gains, as buyers reassess steel equities everywhere.
06 The outlook
The immediate question is whether Brazil can convert its anti-dumping measures into firmer domestic prices, or whether the remaining Chinese volume still overwhelms the policy. CSN’s gain on Thursday suggests some investors still believe the tariff story; Gerdau’s slide suggests the construction story matters more.
Watch for new data on Chinese steel export levels and Brazilian cement or construction activity. A sustained drop in exports would help all Latin mills, while any sign of a building recovery in Brazil would shift the narrative toward Gerdau and away from the current defensive crouch.
07 What to watch
- Chinese steel export volumes: Volumes have been falling all year; a renewed monthly rise would revive margin fears and pressure Gerdau, CSN and SLX.
- Brazilian construction data: Cement sales or infrastructure project approvals would directly signal whether Gerdau’s long-steel order book can improve.
- Mexico nearshoring announcements: New plant or factory investments would reinforce Ternium’s demand story and justify its recent resilience against the global trend.
- Brazil auto production figures: Stronger vehicle output would support Usiminas and CSN, two producers whose flat-steel margins still face heavy import competition.
Why did Gerdau fall while CSN rose?
Gerdau is tied to Brazilian construction, which remains soft, so investors sold despite tariff help. CSN benefited from anti-dumping duties on Chinese flat steel, giving it a session-specific lift.
What does SLX tell us about Latin American steel?
SLX tracks global steel producers. Its 1.78% decline to US$104.80 shows that the cheap Chinese export glut is hurting mills worldwide, not just in Latin America.
Is Mexico a better steel market than Brazil right now?
Mexico’s nearshoring boom and auto orders under USMCA are giving Ternium real demand, while Brazil’s construction cycle is still fragile. That makes Mexico look stronger on demand, even though both face Chinese imports.
Can tariffs save Latin American steel producers?
Tariffs help support domestic prices but have not been enough to offset weak construction demand and global oversupply. Thursday’s session showed investors want to see real orders, not just trade policy.
