# Brazil's Ibovespa falls 13.9% and the real drops 8.2% after Lula wins a fourth term

The National Treasury canceled this week's government bond auctions as investors repriced a fiscal path with public debt above 80% of output and no campaign promise of spending cuts.

Brazilian assets sold off on Monday, the first trading session after President Luiz Inácio Lula da Silva won Sunday's runoff. The Ibovespa [closed down 13.88% at 176,608 points](https://www.infomoney.com.br/mercados/ibovespa-hoje-bolsa-de-valores-ao-vivo-26102026/) after B3, the São Paulo exchange, triggered an automatic trading halt (a circuit breaker). Brazilian outlets reported that the fall was [the index's largest one-day drop since March 2020](https://imirante.com/noticias/brasil/2026/10/26/dolar-sobe-821-bolsa-cai-1388-apos-reeleicao-lula). The dollar rose 8.21% to 5.4029 reais after it touched 5.6049 in morning trading. The National Treasury [canceled the inflation-linked and fixed-rate bond auctions](https://www.intellinews.com/brazilian-markets-tumble-as-lula-wins-fourth-term-478919) it had scheduled for October 27 and October 29.

Lula won about 51.8% of valid votes. His opponent was Flávio Bolsonaro, the senator and eldest son of former president Jair Bolsonaro, who had led in the first round. Part of the market had positioned for a Bolsonaro victory, which investors associated with [tighter spending and reform](https://www.nexojornal.com.br/expresso/2026/10/26/circuit-breaker-dolar-bolsa-de-valores-reeleicao-lula-reacao-do-mercado). The trading on Monday reversed that position.

The fiscal arithmetic drives the selling. [MercoPress reports](https://en.mercopress.com/2026/10/26/debt-inflation-and-a-hostile-congress-the-economic-challenges-of-lula-s-fourth-term?utm_source=feed&utm_medium=rss&utm_content=main&utm_campaign=rss) that Lula begins his fourth term on January 1 with faster growth than forecasters expected and record-low unemployment, but also with fiscal imbalances. Public debt has risen by more than ten percentage points during his current term to above 82% of gross domestic product (GDP), and mandatory outlays leave less than 8% of the federal budget open to adjustment. The president made no commitment to cuts during the campaign. In its final weeks he raised Bolsa Família cash transfers by 15%. The central bank had cut the benchmark Selic rate five times in a row, [to 13.75%](https://www.intellinews.com/brazilian-markets-tumble-as-lula-wins-fourth-term-478919), and the new Congress leans further to the right than the last one.

[Folha de S.Paulo notes](https://www1.folha.uol.com.br/mercado/2026/10/bolsa-avancou-sob-lula-nos-primeiros-tres-mandatos-mas-tera-desafio-de-crescimento-no-quarto.shtml) that the stock market rose during each of Lula's first three terms, all of them periods of strong growth. The economists it interviewed say the challenge now is to sustain that growth without the commodity and credit conditions of earlier decades.

The political dispute adds noise but has so far not threatened the result. US President Donald Trump [called the vote "rigged" and "so corrupt"](https://www.batimes.com.ar/news/world/trump-slams-rigged-brazil-election-after-ally-flavio-bolsonaro-loses.phtml) and did not cite evidence. Washington [imposed a 50% tariff on Brazil last year](https://thehill.com/homenews/6173445-trump-dismisses-brazil-election-results/), partly over the prosecution of the elder Bolsonaro. In Brazil, Kassio Nunes Marques, president of the Superior Electoral Court (TSE) and a Bolsonaro appointee to the Supreme Federal Court, [said the extension of voting hours did not change the outcome](https://en.mercopress.com/2026/10/26/a-judge-appointed-by-jair-bolsonaro-rejects-his-son-s-case-for-annulling-the-election?utm_source=feed&utm_medium=rss&utm_content=main&utm_campaign=rss). He rejected the Bolsonaro camp's argument for annulment.

## What this means

The mechanism is a fiscal risk premium that moves through three channels at once. A weaker real raises import prices. Higher inflation expectations push up local yields. Higher yields raise the Treasury's cost of rolling over debt that already exceeds 82% of output, which feeds back into the fiscal premium. Holders of Brazilian equities, local bonds and unhedged real deposits are the most exposed. Exporters with dollar revenue gain. Lula wants to keep his welfare expansion, and the hostile Congress can block new revenue measures. That combination leaves monetary policy to absorb the adjustment, the outcome sound-money analysts warn about when a central bank inherits a fiscal problem. The precedent is 2002. The real fell steeply before Lula's first term, then rallied once he appointed an orthodox finance team and kept primary surpluses. The consensus now assumes he will not repeat that. The likelier outcome is that the central bank stops its easing cycle at its next meeting and markets stay volatile until Lula names his finance minister and outlines the 2027 budget, which should happen within weeks. If that team commits credibly to the fiscal framework, expect a partial recovery as in 2003. A new spending package sent to Congress before January would prove that read wrong and would push the real weaker.

## What to watch

- Lula's choice of finance minister and first budget statement. A fiscally orthodox appointment would show he intends to repeat 2003, while a spending-focused pick would confirm the market's fear.
- Whether the Treasury restores its canceled bond auctions next week, and at what yields. The clearing rates are the most direct measure of what Brazil now pays to borrow.
- The central bank's next statement on the Selic. A halt to cuts would mean monetary policy is offsetting fiscal risk, while further cuts would add to pressure on the real.
