Key Facts

  • Gold climbs nearly half a percent while the US dollar index edges lower, drawing attention to real assets and carry trades across Latin America.
  • Chile publishes second-quarter GDP early today offering the first hard test of whether recession fears in the Andean bloc are overdone.
  • US futures point higher recovering some of Monday’s decline, which may steady risk appetite for the regional open.
  • Argentine budget data lands this afternoon with an election year making the deficit figures a political flashpoint and a Merval driver.
  • The market board shows the Merval fell 1.77% the deepest decline among the five Latin American exchanges, while Chile’s IPSA rose nearly one percent.

Today’s Focus

The overnight tape is a tale of two forces. Gold and silver rose, with gold up 0.51% and silver up 1.24%, while the US dollar index slipped 0.11%. That combination usually rewards exporters and commodity-heavy indices across Latin America, even when Wall Street closes lower.

Wall Street did close lower, with the S&P 500 down 0.52% and the Dow Jones down 0.51%. But US futures have since turned firmer, suggesting traders see the decline as a pause rather than a breakdown.

Chile’s GDP release this afternoon is the regional pivot. A positive print would reinforce the country’s outperformance, while a weak number could drag the IPSA back down.

Brazil remains a separate story of domestic flows and election-year politics. The market board shows the real rose 0.41%, even as the broader region faced softer pressure.

What matters today. Whether firmer US futures and stronger metals can overcome lingering caution about Chile’s growth and Argentina’s fiscal deficit.

01 The overnight tape in one read

Ibovespa (B3) daily candlestick chart

Global markets overnight were quieter than Monday’s soft close, but the metal complex told a different story. Gold climbed 0.51% to $4,398 an ounce and silver added 1.24%, a sign some money is parking in real assets while the US dollar index eased 0.11%.

US equity futures were firmer in the latest snapshot, with technology and broad-market contracts leading the recovery. European markets were slightly softer, with the DAX down 0.38%, while Asian sessions were mixed to higher — the Hang Seng rose 1.34% and the Nikkei added 0.74%.

The US 10-year Treasury yield rose 0.62%, meaning bonds sold off a touch. That combination — higher yields, firmer futures, softer dollar — usually leaves Latin American currencies supported but keeps rate-sensitive local bonds on the back foot.

For Latin America, the overnight tape matters most through the commodity and currency channels. Higher gold and silver improve the terms of trade for Peru, Mexico, Chile and Argentina, while a softer dollar eases pressure on the real, the peso and the Colombian peso.

Assessment — Gold and Chile Set the Tone MEDIUM

The evidence points to a mixed but not panicked session. Gold and silver are rising, the dollar is soft, and US futures are firmer before the bell. But the region’s own data and politics will decide the mood. Chile’s GDP is the first cue, then Argentine budget numbers. The variable to watch for the rest of the day is whether the US 10-year yield, which rose 0.62%, keeps pressuring rate-sensitive assets.

02 The board before the open

Instrument Level Change Read
US S&P 500 futures 7,823.50 +0.68% Firmer after Monday’s soft close
VIX 14.66 +0.76% Volatility calm but not asleep
Gold $4,398/oz +0.51% Real-asset bid continues
US 10Y yield 4.726% +0.62% Bonds soft, yields nudging up
USD/BRL 5.2016 −0.41% Real firmer, bucking Monday’s mood

The board before today’s open shows that capital is rotating towards real assets and away from the dollar, but without a panic bid into cash or Treasuries. Gold and silver are the clear leaders, while the VIX remains low despite Monday’s slide in US equities.

US futures at plus 0.68% for the S&P 500 and up 1.30% for the Nasdaq offer a psychological cushion for Latin American traders, particularly in growth-sensitive exchanges like Mexico and Brazil.

03 What the data shows — B3 turnover leadership stays with Petrobras and banks

Stock Move Turnover Note
PETR4 R$2,021m Petrobras preferred shares led turnover again
ITUB4 R$836m Itaú Unibanco preferred stock, the banking bellwether
UGPA3 R$783m Ultrapar, a fuel and logistics group
BPAC11 R$722m Banco BTG Pactual units, reflecting financial-sector interest
VALE3 R$712m Vale common shares, tracking iron ore and global growth
EQTL3 R$663m Equatorial Energia, a utilities play on local power demand

Turnover leaders on Brazil’s B3 exchange show where active money sat. Petrobras preferred shares (PETR4) were the clear volume leader with R$2.0 billion traded, a sign that energy and currency moves remain the core trade.

Itaú Unibanco (ITUB4), BTG Pactual (BPAC11) and Vale (VALE3) each saw heavy action too, underscoring that Brazil’s big liquid names — banks and miners — still dominate the local order book.

04 Brazil and the currencies

The market board shows the real moved to 5.2016 per US dollar, a decline of 0.41% on the session. That runs against the softer global dollar, suggesting domestic factors — above all election-year politics and the Selic’s cautious path — matter more for the real right now.

The Banco Central do Brasil cut the Selic to 14.0% in early August, but its cautious tone has supported the currency at times. Foreign selling on B5.2 has been heavy, with an R$5.2 billion outflow on 11 August alone, the largest single-day exit since April 2021.

Despite that, year-to-date foreign flows remain positive, suggesting that investors still see value in Brazilian assets even as they trim tactical positions.

The read-through for today is that the real may stay sensitive to any headline about the Selic or the October election, while Mexico’s peso and Chile’s peso watch their own central-bank and growth stories.

05 The regional setup

Index Country Change
IPSA Chile +0.96%
COLCAP Colombia 0.00%
Ibovespa Brazil −0.09%
IPC Mexico −0.38%
Merval Argentina −1.77%
BVL Perú Peru +0.12%

The regional setup is uneven. Chile’s IPSA was the standout gainer, while Argentina’s Merval was the clear laggard, down 1.77%. Colombia and Peru were essentially flat, reflecting a market waiting for data.

Chile’s stronger showing ahead of today’s GDP release hints that local investors expect a decent quarter. Argentina’s slide matches concern about its budget deficit and currency pressures in an election year.

Mexico’s IPC fell 0.38%, a modest decline that aligns with a cautious attitude towards North American growth and interest-rate expectations.

06 The technical picture

The technical picture argues for patience rather than aggression. The Ibovespa has fallen for ten straight sessions and sits far below its 52-week high near 198,657, according to the market scan, implying the index is deeply oversold but still lacking momentum.

Mexico’s IPC is about 10% below its own 52-week high, while the S&P 500 is within a whisker of its peak. That divergence suggests Latin American indices are trading on local risk premia — fiscal, political and monetary — rather than on a simple US beta.

The VIX remains low at just over 15.19, meaning US investors are not pricing a systemic shock. That should limit contagion to Latin America, even if country-specific stories keep individual exchanges under pressure.

For today, the key technical level to watch is whether the S&P 500 can hold its pre-market gain. If it does, the Latin American region may follow with a cautious, selective rebound.

07 What to watch

  • Chile GDP: Today at 12:30, with consensus expecting a modest expansion; a negative surprise would test the IPSA.
  • Argentine budget balance: Afternoon release; a wider deficit could add pressure to the Merval and the peso.
  • FOMC minutes: Wednesday at 18:00; traders will parse for any shift on the pace of easing.
  • US 20-year bond auction: Tuesday at 17:00; a weak auction could push yields higher and pressure emerging markets.

Frequently Asked Questions

Why is gold rising while stocks are mixed?

Gold is acting as a hedge against a soft dollar and global growth nerves, especially in real-asset and mining-heavy Latin American markets.

Is Brazil the main story in Latin America today?

No. Brazil is just one data point. Chile’s GDP, Argentina’s budget, and the metals trade are equally important for the regional open.

Why did the Merval fall so much?

Argentina faces election-year fiscal pressures and a weak currency, which dragged the Merval down 1.77%.

Which Latin American market looks strongest today?

Chile led with a 0.96% gain in the IPSA, helped by expectations for a solid GDP print and stronger metals.
