Brazil 2026: Lula, the Arcabouco, and Sovereign Rating Trajectory

Why this matters now #

Brazil is the world's tenth largest economy by IMF nominal GDP estimate (USD 2.17 trillion for 2024) and the largest sovereign borrower in Latin America (BRL 7.32 trillion gross general government debt at end 2024 per BCB), yet enters the 2026 cycle with the tightest macro mix since 2015. The Copom raised the Selic to 14.25 percent on March 19, 2025, the highest level since August 2006. IPCA closed 2024 at 4.83 percent (IBGE), above the 3.0 percent target ceiling of 4.5 percent, triggering an open letter from BCB President Galipolo to Finance Minister Haddad.

The fiscal frame is the Arcabouco Fiscal, enacted as Complementary Law 200 of August 30, 2023, replacing the 2016 spending cap (EC 95). It sets a primary surplus midpoint of 0.0 percent of GDP for 2024, 0.25 percent for 2025, and 0.5 percent for 2026, with tolerance of plus or minus 0.25 points, and caps real expenditure growth at 70 percent of the prior twelve months of revenue growth, inside a 0.6 to 2.5 percent corridor. Tesouro Nacional reported a 2024 primary deficit of BRL 43.0 billion (0.4 percent of GDP), inside the lower band after one off exclusions. The 2026 target requires roughly BRL 75 billion of correction in an election year.

The TSE calendar fixes the first round for Sunday October 4, 2026 and any runoff for October 25, 2026. The president elect takes office January 1, 2027. Investors price three calls: Lula reelection probability, Arcabouco compliance without waivers, and the next sovereign rating action by S and P, Moody's, and Fitch.

The 2026 ballot: Lula, Tarcisio, and the post Bolsonaro right #

Lula was inaugurated for his third term on January 1, 2023 after defeating Jair Bolsonaro 50.9 to 49.1 percent in the October 30, 2022 runoff, the narrowest presidential margin in Brazilian history. He turned 80 on October 27, 2025, and confirmed in a March 2026 PT national directorate meeting that he will seek reelection. Vice President Geraldo Alckmin, 73, is expected to remain on the ticket. PT polling internal to the Datafolha and Quaest series in early 2026 showed Lula approval between 41 and 47 percent and rejection between 36 and 41 percent, weaker than at the equivalent point of his 2010 reelection cycle but stronger than Dilma Rousseff in early 2014.

The opposition is fragmented because Bolsonaro is ineligible. The TSE plenary ruled 5 to 2 on June 30, 2023 that Bolsonaro abused his political power and misused public media in a July 18, 2022 meeting with foreign ambassadors, rendering him ineligible until 2030 under the Lei da Ficha Limpa. A second TSE judgment in October 2023 added an additional inelegibility period running concurrently. Bolsonaro has also been indicted by the Procuradoria Geral da Republica in February 2024 over the alleged January 8, 2023 coup plot, with the Supreme Court (STF) accepting the complaint in March 2025.

The plausible right and center right field is led by Sao Paulo Governor Tarcisio de Freitas (Republicanos), a former Bolsonaro infrastructure minister who has built a moderate technocratic profile since taking office in January 2023. Parana Governor Ratinho Junior (PSD), Goias Governor Ronaldo Caiado (Uniao Brasil), and Minas Gerais Governor Romeu Zema (Novo) are positioning. Eduardo and Michelle Bolsonaro are mentioned as proxy options. The unresolved variable is whether the PL party backs Tarcisio at the convention or runs a Bolsonaro family member, shaping first round vote splitting on the right.

Arcabouco Fiscal: design, performance, and 2026 stress #

Complementary Law 200 of August 30, 2023 replaced EC 95's expenditure cap with a primary balance band plus a soft expenditure rule. The primary surplus midpoint targets are 0.0 percent of GDP in 2024, 0.25 percent in 2025, 0.5 percent in 2026, and 1.0 percent in 2027. The tolerance band is plus or minus 0.25 percentage points. Real expenditure may grow at 70 percent of revenue growth, inside a 0.6 to 2.5 percent corridor. Health and education floors (EC 126 and constitutional minimums) are preserved. Breaching the band triggers automatic correctives in the following year, including a freeze on real wage increases for civil servants and on new tax expenditures.

Performance through 2024 was mixed. Tesouro Nacional Resultado do Tesouro Nacional data show the central government posted a primary deficit of BRL 43.0 billion (0.4 percent of GDP) in 2024 once the Supreme Court ordered precatorios payment was excluded under the LDO carveout, inside the lower band of the 0.0 percent target. Gross general government debt rose to 76.1 percent of GDP at end 2024 (BCB), up from 73.8 percent at end 2023, driven by interest costs of 7.7 percent of GDP. The 2025 target of 0.25 percent surplus assumes revenue mobilization from the closure of subvencoes ICMS, the betting operators tax, and the Imposto de Renda minimum tax on dividends proposed by Haddad in March 2025.

The 2026 stress is structural, not cyclical. Bolsa Familia, BPC, and INSS minimum wage indexation absorb roughly 55 percent of mandatory expenditure, and the minimum wage formula (lagged real GDP growth plus inflation) will add roughly BRL 20 billion to the floor. Election year discretionary releases historically add 0.2 to 0.4 percentage points of GDP. Without further revenue measures, Instituicao Fiscal Independente projections from January 2026 show a baseline 2026 primary deficit of 0.3 percent against the 0.5 percent target, a gap of 0.8 percentage points or BRL 100 billion.

Monetary policy, the real, and the DI curve #

The Copom cut the Selic from 13.75 percent in August 2023 to 10.50 percent at the May 8, 2024 meeting in a sequence of seven consecutive 50 basis point moves, then paused. As the real depreciated through 2024 and inflation expectations de anchored, the committee reversed course on September 18, 2024, beginning a hiking cycle that took the rate back to 12.25 percent at the December 11, 2024 meeting and to 14.25 percent on March 19, 2025 under the new BCB President Gabriel Galipolo, who took office on January 1, 2025 succeeding Roberto Campos Neto. The Copom's March 2025 minutes guided to additional restrictiveness, with the Focus survey median terminal rate at 15.00 percent through 2025 H2.

The real depreciated from a January 2, 2024 close of BRL 4.85 per USD to a December 27, 2024 close of BRL 6.18 per USD, a 27 percent depreciation in twelve months, before recovering to roughly BRL 5.85 by April 2026 on commodity strength and the BCB's December 2024 USD 21 billion spot intervention. The Tesouro DI curve flattened sharply: the January 2027 DI peaked at 16.5 percent in early March 2025, while the January 2031 DI traded near 14.8 percent, an inverted curve consistent with credible disinflation expectations beyond 2027.

The Brazil EMBI Plus spread widened from 197 basis points in early 2024 to a peak of 309 basis points in late December 2024, before tightening to roughly 245 basis points by April 2026. CDS five year traded at 175 basis points, tighter than Mexico (188) and Colombia (235), wider than Peru (95) and Chile (88). The Bovespa, in dollar terms, declined 30 percent in 2024, the worst performance among major emerging market indices, before stabilizing in 2025. Multinational issuers (Petrobras, Vale, Itau, Bradesco) priced cross border in dollars at spreads of 175 to 240 basis points over the curve through Q1 2026, indicating that the sovereign ceiling is binding for the bluest names.

Tax reform, energy policy, and the trade frontier #

Constitutional Amendment 132 of December 20, 2023 restructured Brazilian indirect taxation by replacing PIS, Cofins, IPI, ICMS, and ISS with a dual VAT comprising the federal Contribuicao sobre Bens e Servicos (CBS) and the subnational Imposto sobre Bens e Servicos (IBS). Complementary Law 214 of January 16, 2025 set the operational framework, with a transition running from 2026 (1 percent test rate for IBS plus 0.9 percent for CBS) to full implementation by 2032 and ICMS extinction by 2033. The combined reference rate is estimated by Fazenda at 26.5 percent, which would be among the highest VAT rates in the OECD plus emerging market set. A separate Imposto Seletivo on tobacco, alcohol, sugary drinks, fossil fuels, gambling, and select pesticides enters force in 2027.

Energy policy remains contested. Eletrobras was privatized in June 2022 under Bolsonaro through a follow on offering that raised BRL 33.7 billion, but the Lula administration has challenged the federal voting cap (10 percent) at the Supreme Court, with a STF ruling expected in 2026. Petrobras maintained a dividend payout under a revised 2024 policy that pays 45 percent of operating cash flow minus capex, generating BRL 102 billion in dividends in 2024 (down from BRL 215 billion in 2022), with the 2025 plan adding extraordinary distributions tied to the pre salt margin equity sale to the BNDES warehouse. The pre salt equity model, currently allocating government share between PPSA and direct production sharing, is under review.

On trade, the Mercosur to EU association agreement was politically concluded on December 6, 2024 in Montevideo by Lula, Milei, and Ursula von der Leyen. EU member ratification continues, with France leading opposition. The agreement, if ratified, covers 718 million people and roughly USD 22 trillion of combined GDP, eliminating tariffs on 91 percent of EU exports to Mercosur and 92 percent of Mercosur exports to the EU over up to 15 years. Brazil also chaired BRICS in 2025 and hosted the July 2025 Rio summit, where the New Development Bank discussed a local currency settlement framework, a slow moving project that does not yet challenge correspondent dollar clearing.

Sovereign rating trajectory and recommendations #

S and P Global Ratings upgraded Brazil from BB minus to BB with stable outlook on December 19, 2023, citing the Arcabouco enactment, the tax reform amendment, and improved external accounts. S and P revised the outlook to positive on June 4, 2024, signaling another notch upgrade to BB plus on a 12 to 24 month horizon if fiscal targets hold. Fitch upgraded Brazil from BB minus to BB with stable outlook on July 26, 2023. Moody's upgraded from Ba2 to Ba1 with positive outlook on October 1, 2024, one notch below investment grade. The investment grade frontier sits at BBB minus and Baa3, last held by Brazil in September 2015 before the Petrobras corruption fallout and Dilma impeachment cycle.

The base case path through end 2027 has S and P at BB plus by mid 2026 if the Arcabouco 2026 target is met, even at the lower band of plus 0.25 percent, and Moody's at Baa3 by late 2027 if the elected administration confirms the framework. The bear case has S and P holding at BB and Moody's reverting to stable Ba1 if the 2026 target is breached without correctives or if a discontinuist president dismantles the Arcabouco. The bull case (Lula or Tarcisio plus a credible fiscal team) clears BB plus in 2026 and Baa3 by Q2 2027, with the Bovespa and the real outperforming.

For sovereign creditors, the asymmetric trade is owning ten year BRL local debt at the long end of the inverted DI curve, with USD hedge financed by carry, conditional on Arcabouco compliance at the bimestrial revisions. For FX hedgers, December 2026 forwards near 6.10 price a moderate stress scenario; tail risk remains underpriced given 2002 precedent (USD BRL ran from 2.3 to near 4.0). For multinationals, the IBS plus CBS transition creates a six year dual system window requiring ERP and tax engine investment of BRL 50 to 200 million per B3 listed name. For infrastructure investors, the PPI pipeline auctioned roughly BRL 240 billion in 2024 across rail, ports, sanitation, and 5G, with the 2026 to 2027 calendar adding the Norte Sul rail extension.
