Lula Won the Election. Now Comes the Harder Test: Governing.

The re-election of Luiz Inácio Lula da Silva to a fourth term, confirmed by the TSE's official count with 51.79% of valid votes against Flávio Bolsonaro's 48.21%, settles one question and opens several harder ones. The electoral question is resolved. The governance question is not.

Start with the institutional baseline. The TSE certified the result. According to press reports, markets moved violently — the Ibovespa fell 13.88% on Monday, October 26, its worst session since March 2020, triggering circuit breakers for the first time since the pandemic — and Bradesco BBI cut its recommendation on Brazilian equities from overweight to neutral citing concerns about the fiscal agenda and corporate earnings. That is a decisive market verdict on the policy uncertainty embedded in the result. But it is not a verdict on legitimacy. The count is final. What remains open is the question of whether a re-elected government in a deeply divided Congress can actually govern, and whether the institutional checks that matter — the fiscal framework, the Central Bank's independence, the credibility of the rules — will hold.

The arithmetic of Congress is the first constraint. Press reports do not provide a full seat count for the new legislature, so I will not invent one. But the broader reporting makes the landscape clear enough: the ruralist caucus is described as firmly in opposition, and the market's initial reading of the result — reflected in the scale of the selloff — priced in a legislature likely to resist fiscal consolidation measures while remaining open to spending expansion. That is the worst combination for anyone who cares about predictable governance. A government that cannot pass cuts but can pass benefits is a government that accumulates debt. The Tesouro Prefixado 2032 had compressed from 14.15% before the first round to 12.89% at Friday's close; BTG Pactual projected that long-term real yields could exceed 8%, against a historical average of 6.7% during Lula's third term. The bond market is pricing exactly that fiscal deterioration into the curve.

The fiscal picture the re-elected government inherits is not neutral terrain. According to press reports, the package of electoral measures announced by the Lula administration already totals R$356 billion in projected fiscal impact for 2026 and 2027, of which R$88.5 billion were added since September alone. Fitch Ratings was explicit: regardless of the election result, Brazil will face tighter fiscal policy in 2027 — not by choice, but by arithmetic. The 2027 budget, as Valor Econômico reported, was drafted with overestimated revenues and underestimated expenditures. Gross debt was already hovering around 82% of GDP, the government's own projections put it approaching 90% by 2029, and the Selic — held at historically elevated levels — has compressed household consumption growth from 5.1% in the fourth quarter of 2024 to just 0.9% in the second quarter of 2026. GDP growth for 2027 is projected by the Focus median at 1.32%, a figure that has been falling for three consecutive weeks.

If the government pursues the constitutional amendment already being prepared — which, according to Folha and Valor, would allow targeting the center of the fiscal rule and freezing additional budget resources — that would represent a meaningful institutionalist signal. Planning Minister Bruno Moretti signaled to Valor Econômico that the government intends to reopen discussions with Congress on legislation enabling it to aim at the midpoint of the fiscal target. The critical test, however, is the choice of Finance Minister. Folha and Valor report Piauí Governor Rafael Fonteles as the leading candidate, with Vice President Geraldo Alckmin also circulating. The name matters less than the mandate. JP Morgan downgraded its recommendation on the real and government bonds from overweight to marketweight. Goldman Sachs saw selective opportunities but acknowledged little change in the trajectory of public accounts absent a credible signal. Foreign investors, according to Folha, were blunt: without a spending-containment package presented quickly, capital will continue to leave.

The tax reform offers the one genuinely constructive institutional thread in an otherwise turbulent picture. The Receita Federal and the IBS Steering Committee established 25 working groups to coordinate implementation the day after the election, according to press reports. The TCU was set to review the CBS reference rate. This is process working as it should — technical implementation continuing regardless of the political cycle. If the government pursues a credible Finance Minister appointment alongside early signals of fiscal discipline, the reform's implementation could anchor medium-term expectations even as short-term turbulence persists.

The deeper institutional risk is not that Lula won. Democratic elections produce their results and institutions validate them. The risk is that the re-elected government will face a Congress structurally tilted toward spending — with the ruralist bloc in opposition and centrist parties extracting their price for coalition support — while the fiscal space for new commitments is effectively zero. The Ibovespa decline in dollar terms, combined with currency depreciation, could reach 30% by BTG Pactual's estimate. The National Treasury was forced to cancel its fixed-rate and inflation-linked bond auctions and carry out an extraordinary buyback paying yields above 15% on 2029 paper. These are not abstract signals.

The institutionalist prescription here is unchanged by the result: rule-of-law governance requires that the fiscal framework be credible, that the Central Bank remain independent, and that the government signal early and concretely that the electoral spending binge is over. Former Treasury Secretary Jeferson Bittencourt, now at ASA, assessed that adjustments to the 2027 budget proposal will be the key piece for signaling a course correction. A former Treasury Secretary quoted by Valor was more emphatic: action is needed now, before year-end. Both are right.

Brazil has strong institutions. The TSE held. The Central Bank has tools. The tax reform machinery is running. But institutions are only as durable as the political will to work within their constraints. The re-elected government's first weeks will determine whether a fourth Lula term is remembered as the moment Brazil chose fiscal credibility the hard way, or as the moment it discovered how expensive the alternatives are.
