Steel shares across Latin America rose on Monday, 9 November 2026, but the gains owed more to a strong day for markets in general than to any news about steel itself. Gerdau, Brazil’s largest steelmaker by volume, and Ternium, the Mexican-based producer, both gained more than 4%.
The exception was CSN, a heavily indebted Brazilian producer, whose New York shares fell even as peers rose. It has lost 35.61% over 20 sessions and sits far below its January level.
Behind the split lies a simple contrast. Mexico is replacing imported steel with local metal and enjoys strong demand, while Brazil still struggles with cheap foreign steel despite new duties.
What matters today. Steel shares are rising with the market, but only the companies with a clear edge over imports, such as Ternium, have a story that outlasts the rally.
01 The session in one read
Monday was a good day for almost every risky asset, and steel makers, whose profits swing with the economy, joined in. The S&P 500 rose 2.35% and the VIX, Wall Street’s fear gauge, fell 22.31%.
Investors who had sold cyclical shares in recent weeks bought them back. Gerdau and Ternium were the clearest beneficiaries, while CSN slipped 3.80% despite having bounced hard earlier in the week.
The rise in Gerdau, Ternium and the SLX fund fits a day of falling fear and a softer dollar, and the gains came after a poor month for the sector. The evidence for a lasting turn is thin, because the SLX fund is still 3.37% lower over 20 sessions and Brazilian steel faces the same import pressure as before. The variable to watch is whether the SLX fund can hold above US$100 for several sessions.
Steel — the daily wrap.02 The board
The board shows three winners and one loser, and the gap between them is the story. Ternium, with a record Mexican quarter behind it, and Gerdau, with a broad Brazilian and North American business, gained the most.
CSN is the odd one out because it carries heavy debt. Its shares tend to rise sharply on hope and fall on any doubt about its finances.

Latin America — Cross-Market Board
03 Why it moved
The first and heaviest cause was the market-wide rally, with high confidence. The dollar index eased 0.61% and the VIX collapsed, which usually helps companies tied to factories and building sites. The one conflicting signal was the 10-year US Treasury yield, which rose 3 basis points to 4.89%, normally a drag on such shares, so the move looks like a relief rally rather than a rethink of steel.
The second cause was Ternium’s company-specific strength, with medium-to-high confidence. Its third-quarter profit was US$368 million, against a loss of US$270 million a year earlier, and its Mexican shipments grew 18% year on year to a record 2.18 million tonnes. The chief executive attributed most of that growth to winning market share from imports, and the company expects strong domestic sales and pricing through the first half of 2027.
The third cause, with medium confidence, is trade protection. Brazil imposed five-year antidumping duties on Chinese steel earlier this year, which analysts expected to help CSN, yet importers simply moved to other Asian suppliers. That explains why Brazilian names rally less convincingly than Mexican ones, and why CSN could fall on a day when everything else rose.
China’s annual inflation rate was 0.7% in October, below the 0.8% forecast and the 0.9% of September, according to the RT economic calendar. Factory-gate prices rose 5.7% year on year against 5.3% expected and 5.0% before. China is the world’s largest steelmaker, so its price data shapes the import pressure Latin American mills face.
04 The trend behind it
Monday’s gain was a bounce inside a downtrend. The SLX fund is 12.3% below its 12-month high of 113.57 but 31.4% above its November 2025 low of 75.82, and it has lost 7.7% over 60 sessions.
Gerdau is 12.6% below its 20 October high of 5.24, though 40.5% above its March low of 3.26. CSN has been the most violent: it rose 13.27% over five sessions from a low of 0.71 on 3 November, then gave some back, so this looks like a continuation of a weak phase with sharp rallies, not a new one.
05 What it means for Latin America
For Brazil, steel is a story of fairness and survival. Gerdau’s chief executive has called competition from Chinese steel ‘not isonomic, it’s not fair’, and has warned that investment could move abroad without protection. Imports reportedly take about 30% of local steel sales, so every duty matters to the jobs and shares of Gerdau, Usiminas and CSN.
For Mexico, the picture is brighter. Ternium has taken market share from imports, and Mexican prices follow the US market while staying well below it, even with US tariffs on steel at 50%. A Mexico City investor holds the stronger of the two stories.
For a traveller or ordinary saver, the point is practical: steel tracks building and car production, so these shares are a bet on regional growth. They are volatile, and a day like Monday does not change that.
06 The names to watch
Gerdau is the bellwether. It fell 10.89% in 20 sessions, and our own history since 2007 offers a sobering note: in the 88 earlier cases with a fall at least that large, the shares were higher 20 sessions later in 45 cases, or 51%, with a median change of +0.6% and a worst case of -56.6%. History is not a forecast.
CSN is the riskier case. In 14 earlier comparable falls, it was higher 20 sessions later in 6 cases, or 43%, with a median of -2.1% and a worst case of -45.5%.
Usiminas, a petitioner in Brazil’s case against Chinese hot-rolled steel, is worth following for the outcome of that investigation, which we could not confirm. Ternium guides fourth-quarter operating profit broadly in line with the third.
07 What would end it
On the chart, the SLX fund meets resistance at US$100, a round number just above Monday’s close, and then at its 113.57 high; its support is the 75.82 low. Gerdau faces 5.24 above and 3.26 below, and CSN has support at 0.71 and the round US$1 above.
The rally ends if the VIX climbs back or the Treasury yield keeps rising. The bigger test is trade policy: no date is set for a US-Mexico deal or for the review of the USMCA trade pact, and either could reshape Ternium’s outlook. Does the weakness stop? Not until Brazil’s duties start to reduce imports from the new Asian suppliers.
08 What to watch
Frequently Asked Questions
Why did CSN fall when other steel shares rose?
CSN carries heavy debt and has been more exposed to Chinese import pressure, so its shares fell 3.80% even on a strong market day.
Why is Ternium doing better than the Brazilian producers?
Mexican shipments hit a record 2.18 million tonnes as local steel replaced imports, and the company expects strong sales and pricing into the first half of 2027.
What are antidumping duties?
They are extra taxes on imports sold below fair prices, and Brazil applied them to Chinese steel for five years.
Does a one-day rally mean the downturn is over?
No. The SLX fund is still down 3.37% over 20 sessions, and the sector remains well below its June high.
