Paraguay Must Call Brazil's Bluff on Itaipú Before Bolsonaro Returns

The Annex C story is the most genuinely contestable angle in this week's reporting — a small economy's energy sovereignty claim against its giant neighbor, complicated by the fact that Brazilian electoral politics could render any negotiated deal null before the ink dries. Reasonable people looking at the same facts disagree: is Paraguay right to press its claim now, or is it overplaying its hand? That's the column.

The most consequential energy negotiation in South America right now is not taking place in Brasília or Buenos Aires. It is happening along the banks of the Paraná River, where Paraguay is trying to extract from Brazil a fair revision of Annex C of the Itaipú Treaty — the instrument that determines how much Asunción actually receives for co-owning one of the world's most powerful hydroelectric dams. And it is happening, with brutal irony, at precisely the moment when a Bolsonarist resurgence in Brazil's Congress threatens to bury any agreement before it is ever ratified.

This is what sovereignty looks like in practice: not abstract declarations, but kilowatt-hours and royalties and the asymmetric power of a small country sitting beside a giant one that controls the terms of the relationship. The numbers reported this week make the stakes plain. Yacyretá delivered 17.5% more energy to Paraguay's ANDE during the analyzed period, yet simultaneously remitted USD 23 million less to the Paraguayan state under the current Annex C — more energy in, less money back. That is not a technical anomaly. That is the architecture of dependency written into treaty language negotiated under conditions that never served Paraguay as an equal partner. It is, frankly, the same logic that the IMF embeds into its structural adjustment programs: the terms of engagement favor the stronger party, and the weaker one is expected to call this arrangement cooperation.

The historical parallel is worth stating directly. When Itaipú was constructed in the 1970s, Paraguay was governed by Alfredo Stroessner, a dictatorship that signed away hydroelectric sovereignty in exchange for political survival and Brazilian infrastructure dollars. The treaty's compensation formula locked Asunción into receiving a fixed, below-market tariff for energy it co-produces and then sells back to Brazil at whatever price the market dictates. This is the colonial logic of primary-resource extraction applied to water and concrete: you provide the river, we provide the capital, and we write the contract. Decades later, Paraguay is still living with those terms. The revision of Annex C is not a renegotiation born of greed — it is the belated correction of an original injustice.

What makes this week's reporting particularly instructive is the electoral variable. The advance of Bolsonarism in Brazil's Congress, directly tied to Flávio Bolsonaro's lead in the first-round presidential results, creates a scenario where any Annex C agreement negotiated with the Lula government becomes politically fragile before it is signed. A Bolsonaro-aligned Congress would have both the incentive and the institutional capacity to block ratification — or simply to let it languish, which achieves the same result. This is not speculation; it is the operational reality of a bilateral relationship where Brazil's domestic politics consistently override Paraguay's sovereign interests. When the Ibovespa rallies 7.7% on a single polling number, financial markets are pricing in a shift in Brazilian politics that has direct consequences for a neighboring country that never cast a vote in that election. This is what asymmetric regional power looks like when it operates through treaty terms rather than military force.

The Paraguayan government's stated position — that it will not accept a distribution of quotas in the Mercosur-EU agreement that holds back its development — reflects a growing, if still tentative, assertiveness in Asunción's regional posture. This is the right instinct. Paraguay's leverage is real: without Itaipú, Brazil's southeastern industrial complex runs at meaningfully higher energy costs. Without Yacyretá, Argentina faces similar constraints. Small countries in this region have more structural leverage than they typically exercise, precisely because they have been conditioned by decades of asymmetric treaties to underestimate their own bargaining position. The Mercosur framework should function as a mechanism to equalize that leverage — but it will only do so if smaller members are willing to make their demands explicit and collective, rather than managing them bilaterally with the giant in the room.

Here is where intellectual honesty requires a harder assessment. The Paraguayan government's credibility in demanding fair energy terms is complicated by what is happening inside its own institutions. The Ueno Bank case — where a private institution managed more than USD 800 million in public deposits, including Itaipú funds, while regulators failed to detect maneuvers to conceal related-party exposures — reveals that Asunción's demands for sovereign control over its energy revenues coexist with a demonstrated incapacity to transparently manage those same revenues domestically. You cannot credibly demand that Brazil honor its treaty obligations to Paraguay while Itaipú funds disappear into a banking institution whose relationship structure the BCP failed to understand until the crisis was already visible. Sovereignty is not only an external claim. It is also an internal obligation of transparency and governance. Paraguay must honor both simultaneously if its energy diplomacy is to carry weight.

The broader lesson for the region is this: the Itaipú case is not exceptional. It is paradigmatic. Across Mercosur, smaller economies sit atop resources — water, lithium, gas, rare earths — whose value is extracted under terms negotiated in conditions of political and financial inequality, then defended by the stronger parties as binding contracts. The IMF's current program with Bolivia demands subsidy elimination on a timeline that suits multilateral creditors, not Bolivian citizens. Chile's copper royalties fund a state whose own pension system just lost USD 11 billion because fund managers placed leveraged bets on US interest-rate derivatives. Argentina's Vaca Muerta boom is being financialized through RIGI structures that embed investor protections written in New York before being signed in Neuquén.

The revision of Annex C is a small fight in absolute terms — royalties, tariff formulas, transmission fees. But the question it poses is the right one: who controls the terms under which the region's resources become wealth, and for whom? Paraguay deserves better than the contract Stroessner signed. The region deserves a framework where that answer is not determined by who holds power in Brasília on election night.
