Brazil stocks and real plunge after Lula’s surprise reelection win

What happened

Luiz Inácio Lula da Silva secured a fourth term on Sunday, defeating Senator Flávio Bolsonaro 51.8% to 48.2%, according to Brazil's Superior Electoral Court as cited by CNBC. The Financial Times (FT) reported that the upset set off the heaviest selloff in Brazilian markets in decades, because investors had lined up behind a Bolsonaro victory. Reuters reported that the Bovespa index lost more than 15% on Monday, its largest daily percentage drop since 1998, and that exchange operator B3 paused trading for 30 minutes after a 10% fall triggered its circuit breaker. The real dropped over 11% against the dollar in early trading, before trimming that loss to 8.3%, at 5.4274 per dollar.

What it means

The size of the move reflects how one-sided positioning had become. After Flávio Bolsonaro, son of former President Jair Bolsonaro, unexpectedly came first in the October 4 opening round, Brazilian assets rallied hard. By Friday's close, the Bovespa stood almost 7% above its pre-first-round level and the real had gained nearly 5% against the dollar, Reuters reported. Interest rate futures had also priced in lower borrowing costs, on the view that a Bolsonaro government would tighten spending. Prediction markets leaned the same way: Kalshi still gave Lula only a 21% chance shortly after 8:30 p.m. ET on Sunday, CNBC reported, even though opinion polls had pointed to a close race.

When the result flipped, that whole trade unwound at once. Data from Elos Ayta, cited by Poder360, show the Bovespa fell as much as 16.26% early in the session. The worst close on its records since the Real Plan came on September 10, 1998, at minus 15.83%. Elos Ayta noted that nearly all of the index's ten biggest one-day falls were driven by global crises, not domestic politics, which makes Monday unusual.

Government debt was hit too. The 2054 dollar bond fell 2.5 cents to yield 7.45%, and five-year credit default swaps, a gauge of the cost of insuring against a government default, rose to 151.67 basis points from 120.21 on Friday, according to Reuters, citing S&P Global Market Intelligence. Brazil's Treasury called off auctions of fixed-rate and inflation-linked bonds planned for October 27 and 29. Raw sugar, a major Brazilian export, fell 5.6% as the weaker currency rippled into commodities.

In New York, the iShares MSCI Brazil ETF fell between 22% and 28% depending on the time of reading, CNBC and Yahoo Finance reported. Yahoo Finance said Nu Holdings dropped 25% and Petrobras 21% in morning trade, while CNBC said US-listed shares of Itaú Unibanco and Banco Bradesco fell about 20% and nearly 30%. Political uncertainty adds to the pressure: Bolsonaro has refused to concede and has said he will seek to annul the result, according to Reuters. Investors interviewed by Reuters said the choice of finance minister will be the first big test of Lula's fiscal plans.

The bull case

Much of the drop simply erases a rally that only began in early October, so prices are back near where they were before the first round. Lula's team has said it is targeting a budget surplus of about 1.3% of GDP by 2030. If the next finance minister is seen as credible and the transfer of power proceeds smoothly, some of the panic selling could ease.

The bear case

Investors doubt Lula will cut spending enough to steady Brazil's debt, and his team has not spelled out how it would do so. Higher default insurance costs and cancelled bond auctions suggest lenders may demand more to fund the government, raising borrowing costs across the economy. A disputed result could prolong uncertainty, keeping pressure on the real, banks and state-linked companies like Petrobras.
