Brazil Real Strengthens as Ibovespa Rallies
On Tuesday, September 8, the Brazilian real appreciated to 5.0856 per dollar, while the Ibovespa index rose 1.20% to 187,367 points. This movement occurred as Brazil reopened after Independence Day, with markets reacting positively despite global caution regarding US Federal Reserve rate hikes. The stronger real impacts carry trade dynamics by reducing the yield advantage relative to the dollar, though domestic commodity links remain supportive.

Mexican Peso Holds Near 16.92 Ahead of Economic Package
Mexico’s peso remained stable around 16.92 per dollar on Tuesday, September 8, as the S&P/BMV IPC index rose 0.44% to 65,010. Local media noted the peso was "serene" ahead of the government’s delivery of the Paquete Económico 2027, with investors watching for fiscal projections. The stability suggests that current carry trade incentives, driven by the spread between Banxico’s 6.5% rate and the Fed’s 3.5%, are still supporting the peso against moderate political risk.

Argentina Blue Dollar Gap Hits Two-Month Low
In Argentina, the blue dollar fell $5 on Monday, narrowing the gap (brecha) with the official rate to 1.85%, a minimum not seen in two months. By Wednesday, September 9, the official peso was quoted at approximately 1,512 per dollar, while the blue market adjusted accordingly. This convergence indicates reduced speculative pressure and successful Central Bank (BCRA) interventions, although reserves saw minimal change with only $7 million in net gains recently.
Local view
Local financial media in Mexico highlighted the peso’s resilience, with El Financiero describing the currency as "sereno, moreno" (calm and dark/bullish) as it awaited the federal budget proposal. Analysts pointed to the interest rate differential between Banxico and the Fed as the primary driver of this stability. In Brazil, InfoMoney reported that the dollar fell to R$5.08 partly due to shifting electoral polls favoring Flávio Bolsonaro, alongside institutional tensions at the STF, which created a complex but ultimately positive environment for the real. Argentine outlet Ámbito Financiero focused on the BCRA’s pause in dollar purchases, noting it broke a 27-day streak but maintained reserve levels above $50 billion.
