Foreigners Pulled US$2.4 Billion Out of Brazil’s Stock Market in a Single Week, the Most on Record

Brazil · Markets

An election seven weeks away, a fiscal argument nobody has won, and the exit door getting steadily wider.

Brazilian shares have had a bad August, and the reason is not hard to find. B3 foreign outflows reached a net R$12.6 billion — roughly US$2.4 billion — in the single week from 10 to 14 August, the heaviest week on record in a data series that starts in 2008. Add the days on either side and the month is running about R$18.1 billion negative, or US$3.5 billion, with the first round of a presidential election now less than seven weeks away.

The scale of the B3 foreign outflows

The record is a weekly one. Between 10 and 14 August, foreign investors sold a net R$12.6 billion of Brazilian equities, about US$2.4 billion. Because the series being measured begins in 2008, that is the largest week in eighteen years of data — not a week that merely beat everything since 2008.

Inside it sits an unusually ugly day. R$4.7 billion, roughly US$908 million, left on 11 August alone — the biggest single-session foreign withdrawal since 22 April 2021, when R$6.6 billion went out.

Across the first ten trading sessions of the month, through 14 August, the total reached R$18.1 billion, about US$3.5 billion.

One figure keeps all of this in proportion. Even after that selling, the year-to-date foreign flow into B3 equities was still net positive as of 14 August, at around R$18.2 billion — roughly US$3.5 billion. August has been an exit, not a rout, and the two are worth telling apart.

Why the numbers you read do not match each other

This trips people up every month, so it is worth spelling out. You will see R$15.63 billion quoted for August, and you will see R$18.1 billion. Neither is wrong.

The smaller figure comes from Elos Ayta Consultoria, whose series runs only from January 2022 and deliberately excludes money going into IPOs and follow-on share offerings. It also stops on 13 August. The larger figure counts full secondary-market flow and runs to 14 August.

Depending on where you read, you may also have seen R$11.93 billion (seven sessions, through 11 August) and R$13.56 billion (through 12 August). They are all the same story measured on different days.

So when one outlet says record and another says largest since 2022, they are usually measuring different things over different windows. Check the start date of the series and the cut-off date before treating any number as a record.

What the money is pricing

Two things, mostly. The first is October’s election and the fiscal question sitting behind it — what the next government does about a debt path that is already uncomfortable. Brazil’s implicit interest rate on gross debt has reached 13.2% over twelve months, the highest since November 2016, a figure the finance minister himself raised on 19 August. Gross debt stood at 81.9% of GDP in June, the highest in five years.

The second is that the carry trade has stopped being an easy argument. Brazil pays investors well to hold reais — the Selic is 14.00% after four consecutive quarter-point cuts, the last of them on 5 August — but carry only works if the currency does not fall by more than the interest you collect. When the fiscal outlook wobbles, that sum stops being obvious.

There was also a specific trigger. On 11 August JPMorgan cut Brazilian equities from overweight to neutral, citing slowing growth, a deteriorating credit cycle, high real interest rates and volatility around the presidential race. That was the day R$4.7 billion left. Brazilian coverage has drawn the line between the two directly.

What the currency has actually done

Here is the awkward part for the bearish case, at least on a one-year view: the real is stronger than it was. The dollar closed Wednesday at about 5.176 reais, down roughly 0.8% on the day and around 6% below where it stood a year ago.

Zoom in, though, and the picture changes. The dollar was below R$5.00 as recently as April. Measured from the April peak in Brazilian assets rather than from last August, the real has weakened, and that is the window the outflow data covers.

The Ibovespa shows the same split. It closed Wednesday up 0.90% at 167,830, ending its longest run of daily losses since 2023, and sits about 15.8% below the all-time intraday high of 199,355 it set on 14 April.

So: equities bleeding foreign money while the index rises on the day, and a currency that looks strong on a one-year chart and tired on a four-month one. That is roughly what an election premium looks like before the election arrives.

Why this matters if you hold Brazilian assets

If you are invested here, the useful distinction is between flow and level. Outflows tell you about positioning — who is willing to hold Brazilian risk into an uncertain vote. They do not tell you what anything is worth.

If you earn in reais and spend in dollars, the currency matters more than the equity flows. Every 1% the real gives up cuts the dollar value of a Brazilian salary by the same amount, and the forecasts clustered around this election are not gentle.

And if you are simply living here, the daily flow number is not the thing to watch. It is whether the fiscal debate produces anything concrete before Brazilians vote on 4 October, because that is the variable all of this is really about.
