Market Shock

Brazilian assets crashed after President Luiz Inácio Lula da Silva’s surprise runoff victory over Flávio Bolsonaro unraveled bullish bets across local stocks and the real. A controversial last-minute, two-hour voting extension has prompted Bolsonaro to call for the runoff to be annulled.

“Needless to say, the outcome caught most of the market by surprise, with President Lula completing a major turnaround and winning the runoff,” UBS analyst Daniel Pompiani told clients earlier this morning.

The real plunged as much as 11% this morning, while longer-dated interest-rate swap contracts surged almost 300 basis points after hitting trading limits.

Exchange operator B3 widened trading limits for currency, interest-rate, and stock futures for Monday’s regular session to accommodate the volatility. Brazilian stocks last triggered a circuit breaker during the COVID crash in early 2020.

Ibovespa stock-index futures plunged 20%, prompting warnings from trading desks and triggering a circuit-breaker halt.

Traders had positioned for a Bolsonaro victory after his first-round lead sparked a rally and attracted billions in foreign inflows. After Lula’s victory, JPMorgan analysts downgraded their outlook on Brazil’s currency and rates from overweight to market-weight.

“The post-election message of the market is clear: There is no vacation time for the next four years, and the country will need to address the fiscal issue,” said Peter Varga, a senior portfolio manager at Erste Asset Management.

UBS’ Pompiani asked:

Will the BCB intervene? It is very likely, but probably not right at the open. The BCB usually monitors flows and overall market conditions before stepping in, as its focus tends to be on market dysfunction rather than defending a specific level. The first move should be violent, but price discovery will be difficult. With liquidity thin and positioning caught offside, headline levels may matter less than where the market can actually clear risk.

Société Générale analyst Brendan McKenna told clients, “Don’t call it a comeback, Lula’s been here for years.” 

McKenna provided clients with five key points:

1. Lula’s victory in the runoff of Brazil’s presidential election marks an abrupt end to Latin America’s conservative wave and a shift away from the right side of the political spectrum. What began as anti-incumbent sentiment driven by rising crime, corruption, and inflation ultimately culminated in strong support for Lula and his policy platform. While most Latin American countries will continue to be governed by conservative administrations, the region’s two largest economies, Brazil and Mexico, will be led by left-leaning governments. The Latin America election calendar is lighter in 2027 highlighted by general elections in Argentina toward the end of next year. We cannot help but wonder if Brazil pushing back on the right is an indication for a return to Peronism in Argentina or the start of the broader Latam pendulum swinging back left

2. Regardless of whether Brazil’s election marks an inflection point in regional politics, financial market contagion from Lula’s re-election across Latin America should be limited. Brazil’s financial markets are likely to come under significant pressure at the open; however, with most Latin American elections already behind us and many countries having secured more market-friendly policy platforms, we believe any Lula-induced selloff is likely to remain largely idiosyncratic to Brazil rather than trigger region-wide contagion. Argentina may be more vulnerable to spillover effects as regional markets have already demonstrated unease regarding President Milei potentially not being re-elected in 2027. Brazil rejecting a platform similar in style to President Milei could prompt more concern across Argentine local markets, but the extent of any spillover from Brazil’s election should be contained to Buenos Aires.

3. Fiscal discipline is likely to prove more elusive under another Lula administration, and we see little reason to expect a meaningful fiscal adjustment during a fourth Lula term. That said, Lula will face a right-leaning Congress that could constrain his ability to further loosen fiscal policy. A bond market and currency that remain under pressure could also force the government to adopt a more pragmatic fiscal stance to reassure investors, similar to Lula’s efforts to pursue spending restraint after market pressures intensified in late 2024. Should Vice President Alckmin assume a more prominent role in Economy Ministry, and if Finance Minister Durigan continues to emphasize fiscal responsibility, financial markets may stabilize relatively quickly. However, achieving a peak in government debt ratios is likely to remain challenging.

4. Brazil’s Local market selling is likely to be severe, but we will primarily be looking for opportunities to buy BRL. A Lula victory is likely to embed a political risk premium in the currency; however, BRL’s underlying fundamentals remain strong. The real continues to benefit from elevated real interest rate differentials, a manageable current account position, and a central bank with adequate foreign exchange reserves and a demonstrated willingness to deploy them to support financial market and FX stability. In addition, BRL may benefit from the presence of a conservative-leaning Congress that could constrain any efforts by President Lula to further loosen fiscal policy. Should Vice President Alckmin be appointed economy minister and Finance Minister Durigan remain in his role, markets may also take comfort in the continuity and elevated prominence of a technocratic economic team. Our range to watch is BRL5.70-BRL5.75. We would view USDBRL in that range as more interesting to engage in tactical trades to express potentially oversold conditions.

5. Rates may be a little trickier, as the upcoming BRL selloff is likely to push near-term inflation expectations higher, on top of an IPCA trajectory that was already expected to firm through the end of this year and into early 2027. SG Economics now forecasts a slower and shallower Brazilian Central Bank (BCB) easing cycle, which could keep the Selic rate above current market expectations through the end of 2028. As a result, the popular pre-runoff receiver trade may face headwinds for a more extended period, particularly relative to FX markets. Rates pressure should be felt across the curve, but the longer end of the curve should feel pressured most acutely given renewed fiscal concerns associated with the Lula administration. For now, our focus remains on identifying attractive BRL entry points rather than expressing bullish views through rates markets.

Brazil Markets Crater After Socialist Lula’s Shock Victory; Bolsonaro Seeks To Annul Runoff 

Brazilian Senator Flávio Bolsonaro said overnight that he would seek to annul the presidential runoff, challenging a last-minute, two-hour voting extension granted at the request of socialist President Luiz Inácio Lula da Silva’s campaign. The order came from Supreme Court Justice Cristiano Zanin, Lula’s former personal attorney, whom the president appointed to the high court. Lula later won the runoff after Bolsonaro finished first in the first round earlier this month, setting the stage for a legal challenge to the court’s questionable intervention.

According to the electoral court, Lula was re-elected for a record fourth term on Sunday, taking 51.76% of the vote to Bolsonaro’s 48.24% in a surprise outcome.

Via Bloomberg:

Bolsonaro said, “It is impossible to recognize the election outcome given the circumstances in which all of this took place,” adding, “We will pursue legal action and seek to have the election annulled.”

The questionable voting-extension ruling came minutes after polling stations nationwide were scheduled to close at 5 p.m. local time. Zanin later clarified that it applied only to polling stations that remained open.

UBS analyst Justin Wensek told clients, “Flavio’s annulment request is unlikely to hold water given his campaign also asked for additional time in specific states that were impacted by adverse weather.”

The focus now shifts to Brazilian markets, where the “Bolsonaro trade” has reversed and shares of companies across the banking, steel and metals, and oil and gas sectors have plunged:

BANKS, FINANCIAL FIRMS

US-listed shares in lenders fall: Banco Bradesco -27%, Itau Unibanco Holding -28%, NU Holdings -22%, Inter & Co. -32%, Banco Santander (Brasil) -11%

Among other financial firms: PagSeguro Digital -28%, StoneCo -31%, PicS -27% 

STEEL, METAL & MINING 

Among movers: Companhia Siderurgica Nacional -13%, Vale -7.7%, Gerdau S.A. -14% AERO, 

OIL & GAS AND OTHER SECTORS

Among other movers: XP Inc. -39%, Ambev -19%, Embraer -2.6%, MercadoLibre -2.6%, Telefonica Brasil -16%, Companhia Energetica de Minas Gerais -15%, Companhia Paranaense de Energia -17%, Petroleo Brasileiro -19%, Ultrapar Participacoes -18%, Cia de Saneamento Basico do Estado de Sao Paulo (SABESP) -22%, TIM S.A. -17%

iShares MSCI Brazil ETF (EWZ) cratered 27% in premarket trading on the surprise Lula win. 

UBS analyst Wensek added more color on the significant repricing of Brazilian assets as the market readjusts to four more years of socialist Lula: 

Brazil’s fiscal outlook again takes center stage, as debt/GDP trajectory resumes its ominous path. The desk expects a significant re-pricing of Brazilian assets on Monday, as the market adjusts to another four years of Lula, with USDBRL potentially at 5.3 Monday.

Note that FX didn’t react that much in the first round; it was more about rates and equities. EM strategist Roque Montero thinks USDBRL could drift to 5.5-5.6 by end-2026 given December negative seasonality. 

In rates, Roque expects a 100-150bp move higher. Equities could correct by 10-15% based on latest EWZ reaction. Among stocks, watch for selling pressure/rotation out of SOEs, high beta and rate sensitive names, into defensive, USD leveraged, cash flow generative names. If there is a silver lining, Lula will have to build a coalition to pass key policy initiatives through a more right-leaning Senate and Lower House.

Beyond Bolsonaro’s possible court battle to challenge the results, Brazil now faces a financial reckoning as public debt has climbed to 83% of GDP from 71.7% when Lula and the socialists took office in January 2023, leaving traders to digest the continued fiscal deterioration. 

ING analysts see a 5%-7% slide in real terms and double-digit stock losses today. The repricing is already underway offshore: Brazil’s dollar bonds were among the worst performers in emerging markets, with yields on notes due in 2037 jumping 19 basis points to 6.44%.

What Goldman analysts expect from here: 

Rates and equities will see the most damage.  In rates, where we settle will depend on damage control on fiscal.  There are people close to the president advocating for fiscal consolidation given its impact on financing cost.  Market will closely monitor Finance Minister announcement, and the details of fiscal consolidation.  Adjustments involving Constitutional spending cap/ fiscal target would be well received, and trim on specific social programs without longer term commitment likely won’t calm market.  If we see credible fiscal reform, BCB can continue its easing path given the still-very-high real rate, so front-end-to-belly receiver could be attractive again after the correction.  Equity market will likely price out optimism around structural reforms to improve SOE/ business environment.

USDBRL – expect to settle in new range of 5.4-5.8.  This will limit BCB’s ability to accelerate its pace of easing.
