Lula's election triggers Brazil selloff as Argentina faces deeper recession ahead.

Lula da Silva's re-election in Brazil, sealed in a runoff that markets had not fully priced in, opens this week with a jolt to regional assets that arrives at the worst possible moment for Argentina: just as country risk already tops 700 basis points, the dollar-denominated MSCI Merval has touched one-year lows, and the domestic economy is poised to confirm a technical recession before the end of November.

The iShares MSCI Brazil ETF tumbled roughly 20% in Sunday overnight trading, according to Infobae, before trimming part of the loss. Shares of Mercado Libre, which trades on the Nasdaq, slid about 10% in the premarket, while Nubank — the Brazilian digital bank — briefly dropped more than 20%. The logic is straightforward: investors who had placed heavy bets on a Flavio Bolsonaro first-round victory — the Brazil ETF had racked up a 14% gain for the month — began unwinding positions as soon as the results became known, waiting to see whether Lula would opt for fiscal discipline or revert to the spending patterns that drove Brazil's fiscal deficit to nearly 10% of GDP, with an interest bill equivalent to 8% of the economy.

For Argentina, the read is ambivalent and its complexity deserves careful parsing. On one hand, Lula's victory cements Javier Milei as Washington's privileged interlocutor in the region, reinforcing the relationship with the Trump administration at a moment when Minister Luis Caputo has just met with Under Secretary of State Christopher Landau to advance an agenda of U.S. investments of up to USD 20 billion before the end of 2027. On the other hand, a potential depreciation of the Brazilian real — estimated at around 5% by analysts cited in La Nacion — erodes the competitiveness of Argentine industrial exports to its main market, which absorbed 12.7% of foreign sales in the first nine months of the year. The auto sector, which accounts for 64% of what Argentina sells to Brazil in industrial manufactures, is the most exposed.

That tension overlays a macroeconomic backdrop that defies any triumphalist narrative. September exports reached USD 10.036 billion — the highest monthly figure in thirteen years and the first to clear that threshold since then — with year-on-year growth of 23.5% driven by energy. The trade surplus that month was USD 2.976 billion and, measured over the last twelve months, foreign sales have now surpassed USD 100.845 billion, a historical record Quantum highlighted in a recent report. The Central Bank has accumulated purchases of more than USD 1.2 billion so far in October, tripling September's pace, and gross reserves are consolidating above USD 50 billion. Vaca Muerta contributed 698,500 barrels a day in September — 71.7% of national output, which came close to one million barrels — and the Super Niño drove hydroelectric generation up 31.8% year-on-year, pushing spot electricity prices down 42.9% in a single month, according to the RICSA Alyc Electric Monitor.

And yet country risk has added more than 300 basis points from its July lows, closing the week at 707 points, the highest since October 2025. The Financial Times, in an analysis titled "Milei's economic reforms under pressure," captured the paradox precisely: fiscal balance, disinflation from 300% to 34% annually, record exports — and at the same time an economy without momentum, formal employment falling for fourteen consecutive months, and consumption that refuses to take off. Economist Camilo Tiscornia, of C&T Asesores Económicos, put it bluntly: "The biggest risk is political, and from it the other consequences follow."

Activity is, indeed, the worry. The August EMAE showed a 1.7% year-on-year contraction. Industrial production fell between 1.5% and 2.9% year-on-year in September, according to FIEL and Orlando Ferreres's consultancy, respectively, with metalworking at its lowest installed-capacity reading since 2016. Industrial SMEs surveyed by the Fundación Observatorio PyME recorded an 11.9% year-on-year production decline in the third quarter, with the business confidence index at its lowest level in three years. Mass consumption is down 2.7% over the first nine months of the year according to Scentia, with 8 out of 10 households running out of margin by month-end according to Ámbito Financiero. Stellantis confirmed a seven-week shutdown at its Córdoba plant starting December 1, adjusting output to weaker-than-expected demand. La Campagnola suspended 60 workers at its Mar del Plata plant due to mackerel shortages and tuna overstock.

Consultancy Invecq projects that achieving 1% annual growth would require a 2.5% rebound in September followed by 0.6% monthly gains in the final quarter. ECLAC cut its Argentina estimate from 3.3% to 1.9% for 2026, and Morgan Stanley lowered its projection to 1.3%. Finance Secretary Federico Furiase sought to anchor expectations at the 3rd Insurance Summit, arguing that "there is little ammunition to run against the dollar in an election year," in reference to the contraction of the Central Bank's monetary liabilities. The BCRA cut its short position in dollar futures contracts to just USD 42 million as of September 30 — down from nearly USD 6.9 billion a year earlier — restoring FX intervention capacity for 2027.

On the fiscal and regulatory front, the Senate passed the Labor Modernization Law, which includes the elimination of eight national taxes and changes to severance payments and working hours. The privatization of AySA is advancing toward contract signing on November 13, with the winning consortium having paid USD 340.2 million, while regulator ERAS has called a public hearing for today on the tariff redesign that would raise bills for 60% of residential users. The Belgrano Cargas tender, by contrast, faces delays after the withdrawal of its only international bidder, Grupo México Transportes, controlled by Germán Larrea. The YPF case bought some time: the U.S. Supreme Court granted Argentina an extension until December 2 to respond to the plaintiffs' petition.

In the week ahead, local markets will simultaneously process the fallout from the Brazilian election, the Universidad Di Tella government confidence reading — whose September deterioration raised red flags — the fixing of the D30O6 dollar-linked bill on Tuesday, and the Treasury's final October auction on Wednesday. The wholesale dollar closed the week at $1,529.50, up 0.8% on the week and 5.1% year-to-date, well below inflation running at around 33% annually. The gap between that real appreciation of the peso and inflation's resistance to breaking below 2% monthly is, ultimately, the central knot the economic program will have to untangle before the 2027 electoral calendar comes to dominate every conversation.
