LatAm Pre-Open — Friday, July 31, 2026

Source: market close, 30 July 2026.

01 The overnight tape in one read

Equity futures in the United States are pointing to a marginally higher open, with the S&P 500 set to build on Thursday’s solid 1.66% gain. The mood in Asia was steady: the Bank of Japan kept its benchmark interest rate unchanged at 1.0%, a widely expected decision that kept the yen from disrupting the carry trade. European bourses are trading with a positive bias, supported by better-than-expected German employment figures that showed a small increase in jobs against forecasts of a decline.

Commodity markets are providing a quiet but firm foundation. Brent crude is holding above recent troughs, offering a lifeline to oil-linked equities in Brazil and Colombia. Copper, crucial for Chile’s export earnings, is steady in the overnight session, which helps explain the Chilean peso’s poise ahead of this morning’s batch of activity data. The absence of any negative shock from Japan or China—where the official manufacturing PMI held near the expansion line—has kept emerging-market risk appetite intact.

The overarching theme is a gentle softening of the US dollar. The dollar index, which measures the greenback against a basket of major currencies, has edged lower in the overnight session. That move is being felt acutely in Latin America, where the real, Mexican peso, and Chilean peso all strengthened on Thursday. The Merval in Buenos Aires rallied more than 2%, outpacing the region, as Argentine assets continued to draw speculative interest.

02 The board before the open

The board shows a clean sweep of gains across all five major Latin American exchanges on Thursday, a session where global risk appetite aligned with local catalysts. The Merval—Argentina’s main stock index, home to names traded on the Buenos Aires exchange—led the charge, jumping 2.22%. The move reflects continued local demand for equity exposure in an economy where inflation remains punishingly high and stocks act as a store of value for domestic savings.

Brazil’s Ibovespa, the main benchmark for B3, gained 1.88% to close at 177,159, narrowing its distance from the 52-week peak of 198,657 set earlier in the cycle. In Mexico City, the Mexbol—Mexico’s main stock index, also known as the S&P/BMV IPC—rose 1.28%, buoyed by a strengthening peso that slipped below 17.35 to the dollar. Chile’s IPSA and Colombia’s COLCAP joined the rally, setting the table for a session where the primary question is whether the momentum can survive the fiscal and monetary policy data due before the closing bell.

03 What the data shows — a furious rotation under the surface

The B3 turnover table reveals a market in motion, with R$1.27 billion flowing through Vale alone—the mining giant remains the ultimate vehicle for global investors trading Brazil’s commodity story. Ambev and Petrobras preferred shares also drew heavy volume, each above the R$1 billion mark, underscoring a session where liquid, export-linked names anchored the rally.

The real drama, however, is in the tails. Steelmaker Usiminas tumbled 9.3%, the worst performer among actively traded names, as investors fretted about global steel margins and domestic demand. At the other end, footwear and accessories retailer Arezzo soared 20% on turnover of just R$16 million—a move that screams thin-volume positioning rather than a fundamental rethink. Other gainers included Intec, up 8%, and Mauá, up nearly 8%, confirming a risk-on tilt that reached deep into small-cap territory.

04 Brazil and the currencies

The Brazilian real’s 1.14% rally on Thursday, taking the exchange rate to R$5.0593 per dollar, was the standout move in the regional foreign-exchange complex. The currency is now well off its 52-week trough of R$5.59 and trading with a clear tailwind, driven by both the softer global dollar and growing conviction that the central bank’s easing cycle—the Selic, Brazil’s benchmark interest rate, was cut to 14.25% in June—will not reignite inflation in the near term.

The Mexican peso also put in a strong session, firming 0.54% to 17.34 per dollar. The peso continues to benefit from one of the highest real interest-rate cushions in the emerging-market universe, making it a favoured carry-trade destination whenever the Bank of Japan and Federal Reserve stay on hold. The Chilean peso gained 0.81%, with a helping hand from stable copper, while the Colombian and Argentine pesos posted smaller but still positive moves against the greenback.

Today’s currency trading will likely pivot on Brazil’s fiscal numbers at 11:30 am and Colombia’s monetary policy decision later in the afternoon. A credible budget balance in Brazil would give the real licence to test the psychologically important R$5.00 level. In Colombia, a rate hike to 12.50% is expected and largely priced in; the peso’s reaction will depend on the central bank’s forward guidance.

05 The regional setup

Taken together, the regional indices paint a picture of synchronised strength. The spread between the best performer—the Merval at +2.22%—and the laggard—Chile’s IPSA at +0.87%—is tight by historical standards, suggesting a common macro driver rather than idiosyncratic country stories. That driver is the combination of a softer dollar and steady commodity prices, which acts as a rising tide for all of Latin America’s export-oriented bourses.

Colombia’s COLCAP, up 1.64%, is the one to watch today given the central bank’s rate decision this afternoon. A hike to 12.50% would mark continued tightening in a cycle that has weighed on domestic equities but supported the peso. Chile’s IPSA, meanwhile, will take its cue from a dense data release at 1:00 pm local time covering retail sales, industrial production, and the unemployment rate. Any upside surprise in copper production figures—expected to still show a decline, but perhaps a shallower one—would be taken as a positive signal for the index’s heavy mining weighting.

06 The technical picture

The Ibovespa’s close at 177,159 leaves it roughly 10.8% below its 52-week high of 198,657, a level last seen when optimism about Brazil’s fiscal framework and commodity super-cycle peaked. Thursday’s 1.88% surge, on the back of strong turnover in Vale and Petrobras, suggests the index has found a floor in the mid-170,000s and is now testing the upper end of its recent range. The next resistance level sits near 180,000, a round-number barrier that also coincides with the index’s 50-day moving average.

The S&P 500’s close at 7,438 gives a helpful external reference: it is just 2.3% off its own 52-week high, placing it far closer to the top of its range than the Ibovespa. That gap could either be read as a sign that Brazilian equities have more room to run, or as a warning that the local index has underperformed for a reason—fiscal fragility and high domestic rates. Today’s fiscal data will help resolve that debate.

07 What to watch

• Brazil fiscal data (11:30 am): The primary budget balance and debt-to-GDP ratio will either validate the recent rally in the real and Ibovespa or trigger a sharp reversal. Consensus expects a deficit of R$133 billion, narrower than April’s shocker.
• Colombia rate decision (3:00 pm): Banco de la República is widely tipped to raise rates to 12.50%. The market will parse the statement for any hint of how much further tightening is needed, which will move the peso and COLCAP.
• Chile activity data (1:00 pm): Retail sales, industrial production, and copper output are all due. Copper production is expected to remain in negative territory year-on-year, so any upside surprise would boost the IPSA and the peso.
• US employment costs (12:30 pm): The Employment Cost Index is the Fed’s preferred wage-inflation gauge. A reading above the 0.8% consensus estimate would revive fears of tighter US policy and strengthen the dollar, hitting Latin American currencies.

Frequently Asked Questions

What is the main driver for Latin American markets today?

Brazil’s fiscal data at 11:30 am is the single most important release. The primary budget balance and debt-to-GDP figures will set the tone for the real, the Ibovespa, and by extension the entire regional complex.

Why are Latin American currencies rising?

A broadly softer US dollar, combined with the Bank of Japan holding rates steady overnight, has reduced pressure on emerging-market currencies. The real, Mexican peso, and Chilean peso all gained on Thursday and are holding those levels.

What happened in the B3 session on Thursday?

The Ibovespa rose 1.88% in a broad rally led by commodity giants Vale and Petrobras. Steelmaker Usiminas slumped 9.3% on sector-specific fears, while retailer Arezzo jumped 20% on very light volume.

What is the Selic rate and why does it matter?

The Selic is Brazil’s benchmark interest rate, currently at 14.25% after three consecutive cuts. It matters because the high rate attracts foreign capital into Brazilian bonds, supporting the real, but it also dampens domestic economic activity and corporate earnings.
