Brazil's monetary divergence collides with election uncertainty and oil shocks

This week's Copom meeting — scheduled for Tuesday and Wednesday, with a decision expected on the 16th — arrives at a moment when Brazil's central bank and the Federal Reserve are, for the first time in a long while, on the verge of moving rates in opposite directions. While the Copom is expected to cut the Selic by 25 basis points to 13.75%, Kevin Warsh's Fed is signaling a hike of equal magnitude, pressured by US consumer inflation that climbed to 3.4% in August and is refusing to converge fast enough to satisfy the new Fed chair. The result is a transatlantic monetary divergence that is already showing up in prices: bets on US rate hikes have strengthened the dollar and pushed Treasury yields higher, in a move that, according to Folha de S.Paulo, is already spreading across global assets. In Brazil, the dollar closed last week up 0.47% at R$5.1252 — curiously, one session after the release of an August IPCA that registered deflation of 0.32%, the sharpest price drop in four years.

This is the paradox dominating Brazil's current moment: the Lula government's best inflation news in recent memory coincides with an external environment that complicates any continuation of the monetary easing cycle. August's deflation was, to a large extent, an accounting event: the Itaipu bonus drove electricity bills down 7.63%, contributing -0.33 percentage points to the index. Stripping out that factor, IPCA would have come in at 0.01%, and services inflation over 12 months remains at 5.47%, still well above comfort levels. As Valor Econômico points out, low unemployment, growth in the wage bill, and official stimulus are keeping demand hot — hardly fertile ground for a prolonged cutting cycle. The GDP slowdown in the second quarter, with household consumption falling 0.4%, adds complexity to the picture: the economy is decelerating, but not enough to give the central bank room to act liberally.

For markets, the more immediate risk isn't the Copom, but oil. Brent has advanced 3.7%, surpassing US$108 per barrel, pressured by fresh supply disruptions in the Middle East — a variable that, combined with domestic electoral uncertainty and El Niño, clouds the central bank's forward guidance. Analysts at Galapagos Capital consulted by InfoMoney acknowledge this week's cut as the base case but warn that deteriorating expectations could stall the following steps. On elections, Valor Econômico precisely documents how the so-called "electoral trade" is already priced in: the Ibovespa has topped 185,000 points and the dollar has retreated to the R$5.08–R$5.10 range as polls have pointed to a tighter race — but the index's cumulative daily volatility remains around 19%, below the 25% recorded in 2014 and the 22% in 2018, according to Quantum Finance, suggesting the market is digesting political risk without the instability of prior cycles.

The Banco Master scandal continues to deepen and contaminate the financial institutional environment. The Federal Police concluded that BRB (Banco de Brasília) transferred approximately R$17 billion to Master as part of the credit-portfolio acquisition — of which roughly R$12.2 billion were, according to the PF, worthless instruments, the product of what it described as an "industrial" production line of Bank Credit Notes (CCBs), powers of attorney, and consent forms generated automatically and signed in bulk. In testimony to the PF, former Master owner Daniel Vorcaro stated that Banco Central staff would review drafts of the institution's operations before execution — a practice he described as "extremely natural" — and that he had financed international trips and dinners for two employees of Desup, the banking supervision department. The scandal has spilled beyond Master itself: a Coaf report revealed that Isaac Sidney, president of Febraban, deposited R$700,000 into the account of a company linked to Vorcaro and to Fabiano Zettel, the former banker's brother-in-law. The case has reopened the debate over the perimeter of banking regulation and, on the eve of a presidential election, functions as a first-order political detonator.

While the Master scandal dominates banking headlines, Petrobras, whose ADRs trade on the NYSE, faces a credibility crisis of a different nature: the state-controlled company's reversal of a previously announced gasoline price hike, executed without public explanation, was read by the market as evidence of political interference ahead of the vote, according to analysts consulted by Folha de S.Paulo. The perception that the company's pricing policy may be subordinated to the electoral calendar is precisely the kind of risk the market had already priced in — and one that now has concrete anchoring.

On the fiscal front, the Lula government sent the TCU its proposed methodology for calculating the CBS rate, the new federal consumption tax created by the tax reform. Tax specialists estimate the rate will fall between 8.8% and 9.3%; the Senate is expected to define it by December 15. In parallel, split payment — the automatic collection system envisaged in the same reform — has been confirmed for the second half of 2027, on an optional basis and restricted to business-to-business transactions. These are concrete advances for the reform, but uncertainty over the final CBS rate keeps the productive sector's tax planning in suspense. On the spending side, the 2027 budget proposal calls for a 25.4% increase in outlays on the BPC benefit for people with disabilities — a sign that pressure on social spending remains structural, regardless of the election outcome. State-level fiscal analysis also raises a warning flag: Bahia's accounts have deteriorated under Governor Jerônimo Rodrigues relative to the Rui Costa period, even as investments have grown — a pattern that reflects the classic tension between expanding public investment and preserving budget balance.

In corporate credit, the reality of high interest rates is producing a worrying distortion: according to Banco Central data compiled by Bamboo DCM and reported by Valor Econômico, ultra-short-term working-capital credit to companies — operations of up to 365 days — grew 171.8% in the first half of 2026 compared with the same period a year earlier, the second-largest increase in the historical series that began in 2011, surpassed only by the 2020 pandemic shock. The growth reflects companies' inability to access long-term credit at reasonable cost, pushing them into more easily accessible but more expensive facilities — creating a cycle that aggravates the very financial constraint it seeks to circumvent.

On this week's agenda, all attention will be on Super Wednesday, the 16th, when the Copom and the Fed decide simultaneously. The combined reading of the two decisions — and, more importantly, the forward guidance from each central bank — will set the tone for Brazilian assets for weeks to come. The behavior of oil, already above US$108, and the next data prints on Brazilian services inflation will be the most relevant gauges for assessing whether the Selic-cutting cycle in fact has more room to run.
