01 The AI premium unwinds as the S&P slides from its perch

The overnight session carried a distinct shift in mood. A long simmering reassessment of artificial-intelligence valuations is no longer a slow leak. It is a global correction, moving from Taipei to Tokyo to London with impressive speed. The S&P 500 closed at 7,692, down 0.69% on the day, as the Nasdaq led losses with a 1.33% drop to 26,290. The Dow fared better, slipping only 0.22% to 53,343, evidence that defensives are catching the flow that tech is shedding.

The VIX jumped 4.28% to 15.84, its sharpest move in weeks, though the level remains far from panic. Gold fell 2.09% to $4,333 an ounce, an unusual move for a risk-off day and a sign that safety-seeking is going into bonds, not bullion. The 10-year Treasury yield eased to 4.71%, down 0.34% on the day. The dollar index was flat at 99.66.

For Latin America, the signal is mixed but cautionary. A flat dollar during a tech rout suggests the greenback is not yet the haven of choice, which for now cushions high-carry currencies like the Brazilian real. But if the chip sell-off deepens into a broader growth scare, dollar strength typically follows. That would test Brazil’s still-generous Selic carry and the calm in its currency market.

02 A cautious Fed and Brazil’s loud carry trade

The Federal Reserve remains on hold, with the funds rate target range at 3.50% to 3.75%. Against that backdrop, Brazil’s Selic at 14.00% stands out as one of the world’s highest nominal policy rates. The differential is enormous. It funds the carry trade that draws foreign capital into Brazilian local debt and supports the real even when global risk appetite wobbles.

Brazil’s Copom cut the Selic by 25 basis points from 14.25% to 14.00% on 5 August 2026, the fourth consecutive reduction from a 15.00% peak. The unanimous decision extended the easing cycle to 100 basis points, but the committee’s tone was cautious, noting inflation remains above the top of the target range. The interbank CDI rate sits near 14.15%, confirming that financial conditions are still tight despite the cuts.

The carry math is tempting. Real interest rates in Brazil are projected near 8.7% by year-end. Yet the trade is crowded and fragile. Any shift in Fed rhetoric toward renewed tightening, or a sudden dollar bid from a deeper tech unwind, could trigger rapid deleveraging. Brazil offers yield, but it comes wrapped in global beta.

03 Brazil between high carry, politics and a nervous world

The Brazilian real has traded in a narrow band around R$5.22 to R$5.13 per US dollar in early August, barely moved by the Selic cut. The currency’s stability reflects the deep rate differential with the US and the market’s belief that easing will be slow. Year-end Selic expectations cluster near 13.75%, implying perhaps one more quarter-point cut. That leaves policy restrictive enough to weigh on growth while keeping fixed-income returns at the centre of the Brazil story.

The Ibovespa closed 5 August at 177,726 points, down 0.3% in reais year-to-date, about US$32 billion in added market value. In dollar terms the gain is 16.9%, and in euros 20.6%, a strong run for a market still overshadowed by politics and fiscal drift. Yet the index has not fully matched global peers, a gap that reflects investor wariness ahead of presidential elections and persistent questions about the fiscal anchor.

For foreign investors, the current moment demands selectivity. Brazil offers one of the world’s best carry trades and pockets of equity value, but the entry point matters. The chip rout shows how quickly a crowded global narrative can turn, and high-yield EM currencies historically absorb that reversal. The real is stable, but its resilience is borrowed from a Fed that has not yet blinked and a global economy that still believes in AI.

What to watch today and this week
