R$ 7.1 billion. That is what Brazil's National Treasury spent on Monday (26) buying back public debt bonds in a bid to restore order to a market rattled by the reelection of Luiz Inácio Lula da Silva (PT). Spread across the country's population, the sum works out to about R$ 33 per Brazilian, spent in a single morning, according to G1.
For anyone watching the dollar, the shock hit wallets directly. The U.S. currency, which closed Friday (23) at R$ 4.99, jumped to R$ 5.60 at the day's high. A trip with a US$ 1,000 budget became roughly R$ 600 more expensive overnight.
The stock market felt it too. The Ibovespa, Brazil's main stock index, fell more than 10% in the first minutes of trading, triggering a 30-minute halt under the circuit breaker, the mechanism that pauses trading when losses pass that threshold. Around noon, the index was still down 15.81%, at 172,669 points.
What a bond buyback means
The Treasury sells government bonds to finance the public debt, and buyers earn interest in return. When investors get nervous, they demand higher rates, and the price of bonds already in circulation falls, because prices and rates move in opposite directions. By buying bonds back, the Treasury takes paper off the market, makes trading easier (what traders call liquidity) and tries to prevent abrupt price swings, G1 explains.
There were three buyback operations during the day, the National Treasury Secretariat said. The intervention came one day after Lula's victory over Flávio Bolsonaro (PL) was confirmed, a result that caught part of the market off guard and raised uncertainty about the fiscal outlook.
The Central Bank urged caution. Fernando Rocha, head of the bank's Statistics Department, said it is too early to gauge the impact of the currency shock on Brazil's balance of payments, Folha de S.Paulo reported.
"It is far too early to claim any impact today, at 11 a.m. on a Monday, so shortly after yesterday's election result. We have to wait longer to see what the financial market's more definitive reaction will be," Rocha said, according to Folha.
Before the election result, the real had been strengthening as investors bet on a Flávio Bolsonaro victory: from August to the eve of the runoff, the dollar had retreated about 2%, Folha notes. The Focus bulletin, released Monday with responses collected before the vote, projected the currency at R$ 5.05 at the end of 2026, a level the market has already blown past.
