Key Facts
- Overnight rally, the S&P 500 and Nasdaq both climbed, but Brazil closed lower and starts today as the regional laggard
- Peso slide, the Mexican peso fell about 1.4% to roughly 18.7 per dollar, ahead of today’s Mexican inflation data
- Real pressure, the Brazilian currency dipped fractionally overnight, which sets up a cautious tone ahead of Friday’s IPCA-15 inflation report
- Regional divergence, Chile’s IPSA and Colombia’s COLCAP both rose on Wednesday, while Mexico’s IPC jumped 1.4%
- Trading focus, investors are waiting for Mexico’s inflation figures today and Brazil’s IPCA-15 print on Friday before committing to fresh positions
Today’s Focus
Latin American traders face a split screen on Thursday morning. Wall Street continued to grind higher, with the S&P 500 up 0.6% and the Nasdaq up 1.1%, but Brazil’s Ibovespa closed down 0.86% and now sits roughly 1.2% below its record close.
The currencies are also telling different stories. The Mexican peso weakened sharply, the Chilean and Colombian pesos slipped, while the Brazilian real was nearly flat. That suggests nervousness ahead of today’s inflation data from Mexico and Brazil.
Today’s calendar is crowded. Mexico reports inflation and unemployment, Argentina has consumer confidence and retail sales, and Brazil’s IPCA-15 inflation report follows on Friday. The numbers will decide whether regional markets can join the global rally or remain stuck in their own caution.
What matters today. Whether Mexico’s inflation print today, and Brazil’s on Friday, are cool enough to keep local bonds and currencies attractive, or whether sticky prices spoil the mood.

01 The overnight tape in one read
Wall Street ended firmly higher, with the Nasdaq gaining more than 1% and the S&P 500 and Dow also advancing. The VIX volatility index, often called Wall Street’s fear gauge, fell by almost 4%, showing investors are growing calmer.
Europe and parts of Asia firmed too. Germany’s DAX rose 1.4% and the Euro Stoxx 50 added 1.4%, while Japan’s Nikkei 225 gained 0.9%.
The US dollar barely moved against a basket of major currencies. That steadiness helps emerging markets, though Mexico’s peso weakened enough to stand out as a regional concern.
Assessment — Inflation data set the tone MEDIUM
The overnight tape favors global equities, and Latin America usually follows eventually. But Wednesday’s Brazilian sell-off, led by a sharp drop in industrial names like WEG, suggests domestic investors are more worried about local interest rates than about Wall Street’s mood.
If Friday’s IPCA-15 comes in near forecasts of about 0.4% to 0.5% for the month, it might ease fears and support the real. A hotter print could deepen the divergence. Watch the real first, then see if foreign flows return to Brazilian equities.
02 The board before the open
| Instrument | Level | Change | Read |
|---|---|---|---|
| Ibovespa | already in the board | −0.86% | Brazil’s main index lagged badly even as US stocks rallied |
| COLCAP | already in the board | +1.07% | Colombia’s main index rose the most in the region |
| IPSA | already in the board | +0.54% | Chile’s benchmark gained despite the peso slipping |
| USD/MXN | already in the board | +1.40% | the Mexican peso weakened sharply overnight |
| USD/BRL | already in the board | −0.07% | the real was almost unchanged, showing caution before inflation data |
The board shows a region split between winners and losers. Colombia’s market gained the most, while Brazil’s widely diversified index fell despite the positive global mood.
Mexico’s peso stands out as the weakest currency. Its drop suggests traders are nervous ahead of today’s inflation and unemployment figures, which could shift expectations for Banxico, the central bank.

The session read
The Ibovespa eased 0.86%, with breadth positive — 3 of 4 names higher. COLCAP led, while BVL PERÚ lagged.
03 What the data shows — WEG led the Brazil sell-off
| Stock | Move | Turnover | Note |
|---|---|---|---|
| WEGE3 | −7.3% | R$1,268m | the industrial motors maker fell hard and was the third most-traded name |
| HAPV3 | −8.5% | R$114m | the healthcare operator led the losers, sliding on heavy volume |
| AZEV3 | +24.6% | R$16m | the small-cap name jumped, but turnover was light |
| PETR4 | − | R$2,142m | Petrobras preferred shares were the most-traded stock overall |
| VALE3 | − | R$1,852m | the iron ore miner saw the second-biggest turnover, reflecting commodity caution |
The B3 data captures the pain in Brazil. WEG, one of the most valuable industrial companies, dropped over 7% on trading worth more than R$1.2 billion, a clear sign of institutional selling.
Meanwhile, the most-traded names were Petrobras and Vale, both deeply tied to global commodity prices. Heavy turnover there suggests investors were adjusting positions ahead of today’s inflation data, not abandoning the market entirely.
04 Brazil and the currencies
The real was nearly flat, a small movement that masks a bigger tension. Brazil will publish its mid-month IPCA-15 inflation index on Friday, with economists forecasting a monthly rise of about 0.4% to 0.5%.
Those numbers matter because they decide whether the central bank can keep cutting the Selic, its benchmark rate. If inflation comes in hotter than expected, the bank may pause, which would hurt local stocks and support the real at the same time.
Foreign investors are watching this carefully. The Brazilian stock exchange has seen a divergence from Wall Street, and a bad inflation print could widen that gap even further.
Mexico’s peso is the currency to watch today. It fell sharply overnight, and with inflation and unemployment data due at 06:00 Mexico City time, the peso could swing quickly. Argentina’s numbers — retail sales and consumer confidence — may also nudge the Merval, its main stock index. Also due today are Mexico’s Mid-month Core Inflation Rate and Core Inflation Rate (forecast 0.18% each, previous 0.17%), and US Initial Jobless Claims (forecast 200,000), Continuing Jobless Claims (1.72 million) and the Jobless Claims 4-Week Average (200,000), all at 13:30 Lisbon time.
05 The regional setup
| Index | Country | Change |
|---|---|---|
| IPSA | Chile | +0.54% |
| COLCAP | Colombia | +1.07% |
| IPC | Mexico | +1.43% |
| Ibovespa | Brazil | −0.86% |
The regional picture is mixed. Colombia, Chile and Mexico gained, while Brazil slipped; Argentina’s MSCI Merval rose, but local sources disagree on by how much. The cross-country gap reflects different local conditions and interest-rate expectations. Data released on Wednesday: Mexico’s retail sales rose 1.2% in August from July, beating the 0.3% forecast, according to the INEGI statistics agency. Colombia’s Balance of Trade showed a deficit of US$2.77 billion in August, against a US$2.8 billion forecast, as Imports rose 31.7% to US$7.70 billion (DANE). Argentina’s Economic Activity fell 1.7% in August from a year earlier (INDEC). Argentina’s Leading Indicator and Costa Rica’s Balance of Trade readings could not be confirmed in time for this edition.
Mexico’s IPC rose 1.4% to 70,250, but the peso’s sharp drop suggests investors are cautious before today’s inflation data. Today’s mid-month inflation data will set the tone for Mexican assets.
06 The technical picture
Brazil’s Ibovespa closed down 0.86%, about 1.2% below its record close of 209,067 on 9 October. It gave back part of Tuesday’s gain, so short-term momentum is weak, especially given that Wall Street rallied.
Mexico’s IPC jumped 1.4% on Wednesday to 70,250. The peso’s weakness is the real test: a continued slide could pull the stock index back.
Chile’s IPSA and Colombia’s COLCAP are the bright spots. Both rose on Wednesday.
The key technical line to watch is the real. If it holds near 5.02 to the dollar after the IPCA print, Brazilian assets could stabilise. If it breaks decisively higher, meaning a weaker real, the Ibovespa could retest recent lows.
07 What to watch
- Brazil’s IPCA-15 on Friday: the main inflation signal for the Selic; a hot print would pressure local stocks and support the real
- Mexico’s inflation and unemployment data: several indicators arrive together and could shift the peso and Banxico expectations sharply
- Argentina’s consumer confidence and retail sales: both arrive today and may nudge the peso and the Merval
- Foreign flows into B3: the divergence from Wall Street shows local caution; a return of foreign buyers would signal confidence is recovering
