Ibovespa Climbs to 187,367 Points on Oil and Foreign Flows
On Tuesday, September 8, the Ibovespa advanced 1.20% to finish at 187,367 points, extending its winning streak. The index benefited from firm oil prices, which lifted energy heavyweights, and a broader recovery in emerging market sentiment. This performance marks the index's highest level in months, reflecting growing optimism about Brazil's macroeconomic outlook.
Foreign Investors Return with R$1.7 Billion Inflow
After pulling out billions in August, foreign investors returned to the B3 with significant force. On September 3, non-resident investors netted R$1.7 billion in equity purchases, bringing their month-to-date balance to a positive R$3.9 billion. This reversal follows an August outflow of approximately R$18.1 billion, indicating that the dip in August may have been viewed as a buying opportunity by international funds.
Real Strengthens to Near 5.09 Against the Dollar
The Brazilian real appreciated significantly against the US dollar, closing near 5.0856 per dollar on September 8. The currency's strength was supported by both the commodity supercycle—particularly oil—and expectations of further interest rate cuts by the Banco Central do Brasil (Copom). The Selic rate currently stands at 14.00% following the latest cut, and markets are pricing in a gradual easing cycle that supports domestic asset valuations.
Local view
Local financial media highlighted the "electoral trade" and commodity strength as key drivers for the recent surge. InfoMoney reported that the Ibovespa opened higher on September 8, surpassing 188,000 points intraday, fueled by Brent crude approaching $99 per barrel. Estadão noted that tighter polls between President Lula and Flávio Bolsonaro are keeping volatility high, but the market's reaction to economic data has been positive so far. Valor Econômico emphasized the role of foreign flows in stabilizing the index after August's correction.
