2026 is an election year in Brazil, and the debate over the state's role in the economy is back in full force. Presidential candidate Romeu Zema from the Novo party — former governor of Minas Gerais — has released a government plan proposing the privatization of virtually all state companies, including Petrobras, Caixa Econômica Federal, Banco do Brasil, and Correios.
The plan is coordinated by Carlos Costa, a former member of Paulo Guedes' economic team, and fits Zema's strategy of positioning himself to the right and distinct from other liberal candidates like Flávio Bolsonaro (PL). The proposal is bold. But what would it actually mean for stock market investors?
The Eletrobras Precedent
To understand the debate, it is necessary to look at the most recent case: the privatization of Eletrobras in 2022. After years of political discussion, the company was capitalized in a process that raised over R$33 billion, with the federal government reducing its stake and the company gaining private corporate governance.
Results since then have been, in general, positive for minority shareholders:
| Eletrobras Post-Privatization Indicator | Value |
|---|---|
| Net income (latest result) | R$5.6 billion |
| Approximate dividend yield | ~6% |
| Share gain on Apr 14, 2026 | +2.33% |
In March 2026, a review of the Eletrobras privatization was confirmed — a regulatory process provided for in the original contract — analyzing whether divestment and investment commitments were met. This process generates volatility but does not necessarily imply reversal of the privatization.
What Zema Specifically Proposes
Zema's government plan does not establish a detailed timeline, but outlines the target sectors:
| Company | Estimated Value | Notable Feature |
|---|---|---|
| Petrobras | R$500+ billion | Largest company in Latin America |
| Caixa Econômica Federal | R$1.8 trillion in assets | Social bank, low-income housing |
| Banco do Brasil | R$600+ billion in assets | Agricultural credit, cooperatives |
| Correios | ~R$10 billion | Universal postal service |
Privatizing Petrobras would be the largest capitalization process in Latin American history — and likely one of the largest globally. The logistical, regulatory, and political complexity would be monumental.
Caixa and Banco do Brasil present a different challenge: both play the role of public policy agents — low-income housing, agricultural credit, microcredit — that may be incompatible with strictly profit-oriented private management.
Impact for Investors: Possible Scenarios
The privatization of a state company tends to follow a pattern in emerging markets. Before the announcement, there is speculation and volatility. After the decision, there is a governance adjustment phase, cost-cutting, and margin improvement. For shareholders who enter early and hold, historical returns have been favorable — when the process is well-executed.
The Eletrobras case serves as a reference. The company was undervalued before privatization, operated with historical inefficiencies, and the process forced a restructuring that benefited minority shareholders.
However, at least three risks need to be acknowledged:
Political reversal risk: privatizations of strategic state companies like Petrobras are historically controversial in Brazil. A subsequent government may attempt to reverse the process, creating prolonged legal uncertainty.
Execution risk: selling Petrobras to the market would require a deal structure unprecedented in Brazil. Flaws in the process — such as inadequate market conditions, poorly defined control structure, or conflict with regulators — could result in prices below potential.
Public mission risk: public banks like Caixa and Banco do Brasil fulfill functions that the private market tends not to offer profitably — subsidized credit, presence in remote municipalities, low-income housing. Privatizing these institutions would create a vacuum that would need to be filled by other mechanisms.
The Political Calendar Matters
Zema leads polls within the liberal-conservative camp but faces a polarized electorate. For any privatization to happen, he would need a consistent majority in Congress — which, historically, is difficult to achieve in Brazil.
The Eletrobras privatization took years of political negotiation and Congressional approval, even with a committed government. Privatizing Petrobras — with all its symbolic weight and relevance to federal revenue — would be substantially more complex.
What Investors Should Monitor
Regardless of the electoral outcome, the privatization debate tends to:
- Create short-term volatility in state company shares as candidates rise or fall in polls.
- Generate entry opportunities in stocks of companies the market believes will be privatized — but with the risk of disappointment if the agenda stalls.
- Accelerate governance improvements even without formal privatization, as political debate pressures management to adopt more efficient practices.
Brazilian history shows that privatizations, when they occur, tend to appreciate shares in the medium term. But the path from proposal to execution is long and full of obstacles.
