Pix becomes geopolitical weapon as Washington targets Brazil's payment system.

Brent crude at $88 a barrel, U.S. tariffs of 25% on Brazilian goods, and a Pix system now recast as a piece of global financial geopolitics together form a constellation of external pressures on the Brazilian economy that, paradoxically, arrive at a moment when domestic fundamentals are showing signs of relative resilience — creating one of the most interesting tensions of the current cycle.

Start with the external shock. The escalation of the conflict between the United States and Iran pushed Brent to $88.13 on Friday, a 4.63% gain in a single session and the largest weekly increase since April, according to Folha de S.Paulo. On Monday morning, the barrel was hovering around $88.37 on ICE, with fresh strikes reported overnight — the U.S. hit Iranian bridges, Tehran retaliated by striking a power and desalination plant in Kuwait. For Brazil, the policy response was immediate and revealing: the Finance Ministry chose to maintain the diesel subsidy at R$1.12 per liter, deferring a decision that could have offered some fiscal relief. The choice illustrates the permanent dilemma of the Lula administration between budget discipline and shielding transport costs, in a country where diesel fuels agribusiness logistics and food distribution.

Layered on top of this energy backdrop is the trade conflict with Washington. The 25% U.S. tariffs on Brazilian exports, already announced, directly affect roughly 18% of the export basket to the American market, although analysts consulted by Folha estimate that the effective rate falls to close to 16% after the more than 2,100 exemptions granted — including beef, instant coffee, and works of art. The direct dollar impact adds up to approximately $7.2 billion in exports, with São Paulo and Santa Catarina as the most exposed states, according to ApexBrasil. The government responded with a portfolio of reactions still searching for coherence: BNDES requested an additional R$7.25 billion from the Finance Ministry to reinforce credit lines to affected companies; ApexBrasil will announce in August a R$130 million plan for market diversification; the Economic Reciprocity Law remains under discussion, but both Finance Minister Dario Durigan and Vice President Geraldo Alckmin prefer the language of "reciprocity" to that of "retaliation," signaling that the diplomatic escalation will be calibrated with caution. Hugo Motta, president of the Lower House, endorsed the use of the law as a legitimate defense instrument — giving political cover to the Executive without forcing an immediate rupture.

What makes the episode structurally more complex is the technological dimension of the dispute. Pix, the instant payments system operated by the Central Bank, was listed by the U.S. as one of the targets of the trade investigation that justified the tariffs — a signal that Washington sees Brazil's sovereign financial infrastructure as a threat to the dominance of American payment networks. This is a dispute over who controls the rails of money worldwide, as Folha put it, and it sets an unprecedented benchmark: for the first time, the domestic payments system of an emerging country is being treated as a non-tariff trade barrier by the United States. The implications for other countries developing similar systems — India with UPI, Mexico with CoDi — are obvious.

Amid all this external noise, the domestic economy delivered a data point that ran counter to expectations: Brazilian economic activity advanced 0.1% in May, according to the Central Bank, beating market projections even with losses in agriculture. Monday's Focus bulletin confirmed the third consecutive downward revision to the 2026 IPCA projection, which fell to 5.15% — still well above target, but on a descending trajectory. The Selic remains anchored at 14% in year-end projections, and the exchange rate is trading around R$5.10, relatively well-behaved given the magnitude of the external shocks.

Two fiscal data points add nuance to the picture. The government is expected to announce a reduction in the budget freeze this coming Friday, in the Bimonthly Revenue and Expenditure Assessment Report, with the current R$23.7 billion in blocked discretionary spending likely to fall thanks to lower-than-projected growth in social security outlays. At the same time, Congress closed the semester by approving the constitutional amendment for community health agents — an additional R$28 billion in social security spending, according to the Finance Ministry — and the Senate passed a package of "jabutis" (unrelated riders) in the electric sector that power companies estimate could add R$60 billion annually to electricity tariffs, or R$2 trillion over thirty years.

The good trade news comes from Europe. Brazilian exports to the European Union grew by $2 billion in the first two months of provisional implementation of the Mercosur-EU agreement, a 26% increase over the same period in 2025, according to ApexBrasil data previewed by Folha. The figure confirms that the market diversification that Brasília has been touting as a strategic priority is already delivering measurable results — and it comes at a moment when dependence on the U.S. market is beginning to be felt very concretely by the export sector.

Over the coming weeks, three events will define the direction of Brazilian assets: the release of the bimonthly budget-freeze report on Friday, which will be read as a signal of the government's fiscal health; the evolution of the Middle East conflict and its repercussions on oil prices and the diesel subsidy; and the pace of trade negotiations with Washington, where Brasília must decide whether the Reciprocity Law is a real instrument of pressure or one of electoral rhetoric — with presidential elections less than five months away.

**Oncoclínicas (B3: ONCO3)** — Asset manager IG4 Capital is negotiating a R$500 million capital injection conditional on assuming control of the oncology network, with an announcement expected in the coming weeks; in parallel, U.S.-based manager Centaurus reduced its stake from 14.76% to 9.91%, ceding the position of largest shareholder to Latache, which is pushing for a tender offer valued at R$6 billion — nearly seven times the company's market cap.

**Eve Air Mobility (NYSE: EVEX)** — The Embraer subsidiary announced during the Farnborough International Airshow letters of intent to sell up to 46 eVTOLs to Switzerland's Moov and to Shearwater Global Capital, an aviation financing firm owned by Bay Point, while ANAC approved noise criteria for the Eve 100 model, a critical regulatory step toward the aircraft's commercial certification in Brazil.
