Ibovespa extends rebound as banks and cheaper oil lift sentiment
The Ibovespa rose 0.44% to 187,423 points on Tuesday, September 22, with the real strengthening to 5.1029 per dollar as cheaper oil lifted equity sentiment. The close sits in the upper part of the index's annual range, following Monday's 0.74% gain to 186,596, led by banks amid global risk appetite. Local media noted Petrobras was key to sustaining the index earlier in the week, with WTI falling back below the symbolic US$100/bbl level for a fourth session of losses.
Copom minutes signal measured easing after fifth straight cut
The Copom minutes released Tuesday follow the fifth consecutive quarter-point cut, to 13.75% on 16 September. The minutes state the size of the easing cycle will be adjusted as the scenario develops, keeping policy contractionary, and note that inflation in Brazil is still demand-driven. Economists surveyed by Bloomberg lowered their 2026 year-end Selic forecast following the cut as the economy gradually cools ahead of the October presidential election.
Real stands out as election race stays tight
The real has been a standout among emerging currencies as Brazil's presidential election race remains tight. The prospect of a change in government is fueling demand for Brazilian stocks and the currency, though strategists warn fiscal risks remain elevated under either candidate. Election-adjacent polls and the currency's strength were recurring themes in local coverage of Monday's and Tuesday's sessions.
Blue chips sidelined as broader market drives rally
On Monday, September 21, the Ibovespa recovered with global optimism and election-news momentum despite Vale and Petrobras acting as drags, per Valor Investe — the rally was broad-based rather than reliant on the two heavyweight names. The dollar fell to R$5.10 that session, and Exame reported banks leading gains in a day of global risk appetite.

Local view
Local financial media are focused on the interplay of the Selic easing cycle, October's election and oil prices. Forbes Brasil reported the index up 0.47% to 187,500 points with the dollar at R$5.10, with the Copom minutes and election scenario supporting gains and Petrobras sustaining the Bolsa. InfoMoney flagged the Brazil–US interest-rate divergence as a potential opportunity for the Bourse, noting the Fed is holding rates high against the energy shock while the BC has begun cutting the Selic. InfoMoney's live blog also tracked EWZ, the main Brazil ETF, signaling foreign investor entries at the start of the week.
