Foreign investors pulled billions from Brazilian shares in August 2026, the worst month of the year. The Ibovespa index still dipped slightly, before rallying hard in the final stretch.

August Outflow

Foreign investors withdrew about 18.1 billion reais (US$3.5 billion) from Brazilian shares in August 2026. InfoMoney called it the worst month of the year for foreign investors, citing data from B3, Brazil’s main stock exchange.

B3 runs Brazil’s stock market and clearing systems. It publishes data on investor flows that Brazilian media report on.

Preliminary Numbers, Different Methods

Media outlets reported different figures during August, since B3 data updates daily. InfoMoney’s early tally, through 27 August, showed a negative balance of 18.4 billion reais (US$3.6 billion).

A separate JPMorgan analysis, reported by Revista Oeste, put August’s outflow at 22 billion reais (US$4.2 billion). JPMorgan called it the third-largest monthly outflow from Brazilian shares since 2008.

The Final Tally

By early September, InfoMoney reported the full month’s total: a net outflow of 18.1 billion reais (US$3.5 billion). It called this the worst month for foreign investors in all of 2026.

The gap between InfoMoney’s estimates shows how B3 data shifts as more trading days close. The final total still marked the deepest monthly loss of the year.

A Rough Start, Then a Reversal

Early in August, foreign investors sold heavily, pulling out about 23 billion reais (US$4.4 billion) by 20 August. CNN Brasil reported that outflow using B3 data through that date.

After that, roughly 5 billion reais (US$1.0 billion) flowed back in during the rest of the month, CNN Brasil said. That reversal trimmed the final outflow to about 18 billion reais (US$3.5 billion).

One Day Turned Positive

Not every day in August was negative for foreign investors. On 27 August alone, B3 data showed a net inflow of 208 million reais (US$40 million).

That single day of buying was small next to the month’s losses. But it hinted at the partial recovery that followed in late August.

Why Foreign Investors Sold

Analysts pointed to caution ahead of Brazil’s elections and worries about the government’s fiscal plans. Money Times reported that JPMorgan and Morgan Stanley both grew more cautious on Brazilian shares in August.

Both banks cited a slowing economy and rising credit risks in their notes. Those views likely fed into the foreign selling that outlets tracked through the month.

The Ibovespa’s Bumpy August

Brazil’s benchmark stock index, the Ibovespa, actually fell about 0.3 percent in August 2026, InfoMoney reported. That is a small move, but it followed a wild month for foreign investors.

The index fell for 11 straight sessions from 4 to 18 August, tracking the heaviest foreign selling. It then rose for nine sessions in a row into September, InfoMoney said.

Not the First Swing This Year

August was not the first month with unusual foreign flows in 2026. In July, foreign investors added 4.3 billion reais (US$0.8 billion) to Brazilian shares, InfoMoney reported.

Earlier in 2026, foreign investors had also poured large sums into Brazilian shares, especially in January, according to Money Times.

A Record Streak of Selling

The consultancy Elos Ayta tracks B3’s foreign investor data back to January 2022. ADVFN reported that August’s outflow became one of the two largest in that entire record, alongside May 2026.

Einar Rivero, the consultancy’s founder, compiled the analysis using B3’s own trading data. It excluded new share offerings, focusing only on shares already listed on the exchange.

Foreign Investors’ Role on B3

Foreign investors have long been one of the biggest groups trading shares on B3. That is why their August retreat drew so much attention from Brazilian financial media.

When foreign investors sell heavily, it can weigh on share prices even if local buyers step in. Their August exit tested how much the market could rely on domestic demand alone.

The Brazilian Real

The US dollar closed at about 5.18 reais on 31 August 2026, according to CNN Brasil and InfoMoney. That is a reference point for the size of these flows.

A weaker real can make imports pricier for Brazilians and change returns for foreign investors. Currency moves depend on many factors, not just stock flows.

What Comes Next

Investors will watch whether foreign investors keep selling or return to buying in September. Early September data already showed the Ibovespa extending its winning streak.

If foreign investors come back, it could support further gains in Brazilian shares. If they keep selling, the rally may depend more on local buyers.

Background on B3

B3 is Brazil’s main stock exchange and clearing house, based in São Paulo. It lists shares of the country’s largest companies and publishes daily investor flow data.

Brazilian and international media routinely summarize this data. Because B3 updates its figures as more trades settle, early estimates often change once a full month closes.

Methodology Differences

B3’s own daily data, InfoMoney’s tallies, and JPMorgan’s bank research are three different ways to measure the same trend. Each uses a different cut-off date or counting method.

That is why one report said 18.4 billion reais and another said 22 billion reais for roughly the same period. Both describe real selling by foreign investors, just measured differently.

Sources and Verification

This article relies on reporting from InfoMoney, CNN Brasil, ADVFN News, Money Times, and Revista Oeste, all citing B3 or JPMorgan data. Figures for August varied slightly by date and methodology.

The final, most complete figure for August is InfoMoney’s 18.1 billion reais (US$3.5 billion) total. That is the number this article treats as most reliable.
