In a financial column published by Reuters, Jamie McGeever reports that global investors are extending a tech-led equity rally driven by artificial intelligence optimism, setting the stage for the Federal Reserve’s upcoming policy decision on Wednesday.
The Bottom Line
- Global markets are leaning into a broad tech rally powered by artificial intelligence momentum, helping US stocks recover from recent gloom as investors await the Federal Reserve’s policy verdict.
- Brazilian financial markets experienced historic turbulence following President Lula’s election victory, with the Bovespa stock index tumbling 14% and the real declining sharply before a modest 1% rebound, though spillover into developed markets remained negligible.
- Major US hyperscalers including Microsoft (NASDAQ: MSFT), Alphabet (NASDAQ: GOOGL), and Amazon (NASDAQ: AMZN) are scheduled to report third-quarter earnings, focusing market attention squarely on cloud growth and massive artificial intelligence capital expenditures.
Global Equities Lifted by Artificial Intelligence Demand Ahead of Fed Decision
Investors are riding a wave of artificial intelligence optimism that has reversed last week’s market gloom, propelling US stocks higher on Tuesday, according to the Reuters commentary. Lower oil prices and a steady bond market provided additional support as attention pivots to the central bank.
The broader macroeconomic backdrop features real US interest rates sitting among the highest in the developed world alongside a flattening yield curve.
Evaluating Brazilian Market Carnage and Global Isolation
While technology stocks advanced globally, Brazilian financial markets absorbed severe losses following President Lula’s re-election victory. Brazil’s benchmark Ibovespa equity index tanked more than 17% intraday before closing down 14%. The Brazilian real crashed 12.5% toward support around the 5.6 level against the US dollar before paring losses to 10%.

Brazilian bond losses were dramatic, with yields surging 230 to 250 basis points across the curve. In response, Citi closed its Brazilian risk trades, and Morgan Stanley downgraded Brazil to equal-weight. Despite the historic domestic sell-off, MSCI’s global emerging markets index lost only 1% on Monday and largely recovered on Tuesday, demonstrating that Brazil’s relatively closed economy insulated developed markets from significant spillover.
