LatAm Pre-Open — Wednesday, September 23, 2026

Latin American markets — Source: RT close, 2026-09-22. Figures rendered directly from the feed.

01 The overnight tape in one read

Asia and Europe handed Latin America no unified signal. Japan’s composite purchasing managers’ index, a survey of private business activity, landed at 54, a touch above forecasts, while German Ifo business-climate data arrived marginally firmer at 89 — neither enough to reprice the global dollar or yields.

Wall Street closed mixed on Tuesday: the Dow fell 0.36%, the S&P 500 was flat and the Nasdaq gained 0.45% to a record. Monday had been the strong session, with the S&P 500 up 1.49%.

Brent crude, the global oil benchmark most relevant to Latin America, is down 2.3% near US$99.25 a barrel. For producers Colombia and Brazil that is a small headwind; for Chile and Mexico, both net importers, it is a small relief.

The underlying mood is one of caution around duration. The US 10-year Treasury yield sits near 4.97%, and that keeps the cost of dollar funding high enough that local carry — the premium for holding Latin American assets — remains the main draw for foreign money.

02 The board before the open

The board shows a firmer dollar and higher long US yields alongside lower oil — the classic setup for Latin American equities to lag US tech strength. The VIX, Wall Street’s fear gauge, falling to 14.21 says the global mood is calm, not panicked.

Silver’s gain is a modest plus for Peru, where the BVL index rallied 1.84% in the prior session. Gold is only marginally lower, so mining-heavy boards should not expect a tailwind from the metals complex today.

03 What the data shows — Brazil’s turnover leaders rotate to banks

The scan shows money concentrated in Petrobras, B3, Vale and the big banks. Petrobras preferred shares absorbed R$2,361m of turnover alone, so the softer Brent price matters for the most traded name on the board.

Gainers were led by Alpargatas (ALPA4), up 4.7% on R$33m, and Locaweb (LWSA3), up 4.5% — small-cap momentum rather than index leadership. The loser to note is TASA4, down 10.7% on R$39m, a sharp single-stock move in Taurus Armas, the firearms maker.

04 Brazil and the currencies

The real opens near R$5.10 to the dollar, little changed, after the central bank’s quarter-point Selic cut to 13.75%. Money markets price the benchmark rate at 13.50% by year-end, so the carry cushion versus the US remains wide.

The central bank’s inflation report and consumer confidence are due this morning, giving local traders a domestic anchor. B3 shares trade ex-interest on equity from today, meaning the price reflects a dividend adjustment after the September 22 record date.

A firm dollar index at 100.603 is a mild headwind across the region’s currencies. Mexico’s peso traded near 17.29 to the dollar after weakening 0.42%, and Colombia’s peso slipped 0.86% to 3,203 — the clearest currency reaction to cheaper oil.

Chile’s peso is the relative standout, with the USD/CLP pair easing 0.23% to 947. The central bank’s monetary policy meeting minutes, released this morning, should confirm the cautious easing path that has supported the Santiago currency.

05 The regional setup

The prior session’s board shows Colombia’s COLCAP leading the region with a 0.90% gain, while Argentina’s Merval was barely changed, down 0.04%. Chile’s IPSA climbed 0.61%, and Brazil’s Ibovespa added 0.44%, two straight up days.

The setup into today’s open is less uniform. Colombia’s gain runs into cheaper oil, Mexico faces a rate decision on Thursday, and Argentina has economic activity and retail sales on the calendar. Argentina’s peso is held near 1,514 to the dollar under a crawling-band policy.

06 The technical picture

The Ibovespa closed at 187,423, still 5.7% below its 52-week high of 198,657 but well above the 140,680 low. The index has stabilised after a period of weakness, and the two consecutive up sessions hint at a short-term floor forming.

Mexico’s IPC remains the regional laggard in breadth terms, sitting 11.1% below its 52-week high of 71,601. At 63,647, the index needs a convincing break back above its recent range before foreign investors treat it as more than a carry proxy.

B3’s heavy turnover in banks and energy suggests institutions are positioned for range-trading rather than a breakout. The real’s steadiness near 5.10 to the dollar is the quiet anchor; a decisive move below 5.00 would change the flow picture for Brazilian exporters.

07 What to watch

• Banxico rate decision on Thursday: Mexico’s hold and guidance set the peso’s near-term path and the tone for local bonds.
• Brazil BCB inflation report: Any signal on the pace of Selic cuts shifts the real and bank-heavy index.
• US flash PMIs: A surprise in the September purchasing managers’ surveys moves the dollar, yields, and by extension regional FX.
• Brent crude direction: A break below US$99 tightens the squeeze on Colombia and Brazil’s oil-linked receipts.

Frequently Asked Questions

Why is Mexico in focus?

Banxico publishes its rate decision on Thursday, 24 September, with mid-month inflation data due first. That makes it the region’s next big policy event.

What does softer oil mean for Latin America?

It pressures oil exporters Brazil and Colombia while easing import costs for Chile and Mexico.

Why does Brazil’s Selic still matter so much?

At 13.75%, the Selic keeps the real’s carry far above the US, drawing foreign funds into local bonds and equities.

Is the region opening up or down?

It is selective: mixed US futures, lower oil and a firm dollar point to modest pressure, with no single broad driver.
