Today’s Focus
Brazil’s iron-ore miners fell on Monday as the country’s stock market crashed. Vale, one of the world’s largest iron-ore producers, dropped 3.23% to US$12.00 in New York.
CSN Mineração, a smaller Brazilian miner, lost 6.21% in São Paulo to R$4.68 (about US$0.86). Rio Tinto, a global miner whose iron-ore mines are in Australia, rose 0.36% to US$83.72.
Vale fell far less than the Ibovespa’s 13.88% because it earns dollars, and the dollar’s 8.79% jump against the real makes those dollars worth more in local currency.
What matters today. Vale held up better than most Brazilian shares, which shows how exporters can cushion a currency shock, though the miner still fell.
01 The session in one read
Iron-ore shares split on Monday, 26 October 2026. Vale fell 3.23% to US$12.00 in New York, while Rio Tinto rose 0.36% to US$83.72.
In São Paulo, CSN Mineração lost 6.21% to R$4.68 (about US$0.86). The decline fits the wider Brazilian sell-off that followed Lula’s re-election.
We have no verified iron-ore price for the session, so the board shows listed miners and a steel-linked fund as proxies.
The evidence points to Brazilian miners being hit by the country’s shock but cushioned by their dollar revenue. Vale’s fall of 3.23% was much smaller than the Ibovespa’s 13.88%. The variable to watch is Vale’s results on Thursday, which will show whether costs or demand are the bigger issue.
02 The board
Vale’s 3.23% drop to US$12.00 was the sharpest move among the global names. Rio Tinto’s 0.36% gain to US$83.72 shows the pressure was specific to Brazil.
BHP, another global miner, rose 1.64% to US$79.13.

03 What moved it
The main driver was Brazil’s political shock. Investors sold Brazilian assets after Lula’s re-election, and the dollar jumped 8.79% against the real.
A weaker real lowers Vale’s costs in dollar terms, since many of its expenses are in reais. That helps explain why the miner fell less than the market.
US markets were steady, with the S&P 500 up 0.70%.
04 The Latin American read
For Brazil, iron ore is a national export question. Vale is among the country’s largest exporters, and its shares track both the price of ore and the real.
The dollar’s 8.79% jump to 5.4154 reais changes the maths for miners and for Brazil’s trade balance.
Brazil’s central question is whether the political shock lasts. Vale’s result on Thursday gives the first corporate read.
05 The names to watch
Vale is the dominant Brazilian name and carries the most event risk before its results on Thursday. Its US$12.00 close sits near Monday’s low of US$11.78.
Rio Tinto and BHP matter as relative-value signals. Both rose, which suggests investors saw Brazil as the problem, not iron ore.
CSN Mineração fell 6.21% in São Paulo, in line with domestic-facing Brazilian shares.
06 The outlook
The near-term path depends on Brazil’s political aftermath and on China’s steel demand, which sets the global ore price.
If the real stabilises, Vale could recover part of Monday’s loss. If it slides further, exporters may gain relative to the market.
07 What to watch
- Vale results: The miner’s quarterly report is due this week.
- Brazilian real: A further slide could help exporters but raise inflation.
- Rio Tinto and BHP: Whether they keep rising as Brazilian rivals fall.
- China steel demand: The main driver of global ore prices.
