By Brazil Stock Guide – Foreign investors withdrew R$ 14.91 billion from B3 in May, the largest monthly outflow from Brazil’s stock exchange since January 2022, according to a survey by Elos Ayta based on B3 data.
The figure considers only secondary-market trading, excluding IPOs and follow-ons. Including equity offerings, the net outflow reached R$ 13.27 billion, also the worst monthly reading in the series analyzed since 2022.
The reversal came after a powerful start to the year for Brazilian assets. Foreign investors added R$ 26.31 billion to the stock market in January, followed by inflows of R$ 15.40 billion in February and R$ 11.66 billion in March.
Profit-taking
The most direct reading is that May was a month of profit-taking. After the sharp appreciation of Brazilian assets in the first months of 2026, some global investors reduced exposure as the external backdrop became less supportive.
High interest rates in the U.S., a partial rotation back into developed markets and renewed caution over Brazil’s fiscal outlook helped turn the flow negative.
The move coincided with a sharp correction in local stocks. The Ibovespa fell 7.22% in May, its worst monthly performance since February 2023. The dividend index, IDIV, dropped 7.62%, its weakest month since June 2022.
Lower conviction
Trading data show that the shift was not only about net selling. Foreign participation also lost intensity.
In March, international investors traded more than R$ 500 billion on both the buying and selling sides, the highest level in the recent series. In May, purchases totaled R$ 379 billion, while sales reached R$ 394 billion.
That gap explains the negative balance, but the lower turnover also points to a more defensive stance. Foreign investors have not abandoned Brazil, but they became less aggressive after an exceptional first quarter.
Still positive
Despite the record outflow in May, the year-to-date balance remains positive. From January to May, foreign investors accumulated net inflows of R$ 41.63 billion in the secondary market. Including IPOs and follow-ons, the figure rises to R$ 43.78 billion.
That is the key point. May marks a relevant change in direction, but not necessarily a break in the Brazil trade. Foreign capital remains one of the main supports for liquidity and valuation in the local stock market this year.
What changed is the price of conviction. Brazil is no longer just an obvious bargain after the rally. Investors now want a more benign U.S. rate environment, less fiscal noise at home and clearer evidence that corporate earnings can sustain equity prices.
May’s outflow shows that foreign investors are still willing to buy Brazil. It also shows that, when gains appear, they are willing to take them.
