The Brazilian ETF market closed the first week of August predominantly in negative territory, tracking the pullback in BOVA11. The period was marked by key monetary policy decisions and volatility in the international commodities landscape.
During the week under review, the Brazilian equity market pulled back, with the BOVA11 ETF recording a negative performance of -3.23%. The Brazilian stock exchange opened August in the 178,000-point range and closed the week under downward pressure, near 172,500 points.
This contraction in the Ibovespa occurred during the same week as key monetary policy decisions. On August 5, 2026, the Monetary Policy Committee (Copom) cut the Selic interest rate by 0.25 percentage points, moving from 14.25% to 14.00% per year. This marked the fourth consecutive cut. In its statement and across local interest rate futures (DI), the Central Bank adopted a cautious tone, citing uncertainties surrounding armed conflicts in the Middle East and unclear monetary policy trajectories in advanced economies. Inflation expectations (IPCA) projected in the Central Bank’s baseline scenario for 2026 stood at 5.1%.
Concurrently, producer and wholesale inflation data showed a decline. July 2026 IGP-M registered deflation of 1.16% (accumulating 2.76% over 12 months), while IGP-DI fell 0.86%. The drop in these indicators was driven by declines in raw commodities such as soybeans, coffee, cattle, and iron ore.
Sectoral Impact: Commodities, Basic Materials, and Utilities
ETFs with significant exposure to commodities suffered the week’s most severe impacts. CMDB11 (Commodities) dropped -3.81%, and MATB11 (Basic Materials) fell -2.19%.
The week’s news flow explains this selling pressure:
-
Oil: International prices experienced significant devaluation (with both WTI and Brent crude falling around 5% during one of the week’s sessions). The move was triggered after US President Donald Trump stated he had canceled a planned strike on Iranian energy infrastructure. Furthermore, expectations emerged regarding the reopening and normalization of shipping routes in the Strait of Hormuz, stripping away part of the commodity’s geopolitical risk premium. OPEC+ also announced its decision to increase production by 188,000 barrels per day in September, adding to global supply.
-
Iron Ore: The commodity traded lower on the Dalian and Singapore exchanges, pressured by analysts’ forecasts of declining Chinese demand for steel. This environment heavily penalized companies in the sector that make up Brazilian basic materials indices.
The utilities sector (UTLL11, down -1.90%) and cyclical sectors of the economy (BCIC11, down -3.32%) followed the broader domestic equity market’s negative trend.
Financial Sector Performance and Foreign Exchange
The financial sector concentrated the heaviest losses in the sample. FIND11 retreated -5.27% and BNKS11 fell -4.26%. The sharp decline reflected the overall risk aversion across the Ibovespa and the potential repricing of banking margins following the confirmation of the Selic rate cut to 14.00%, aligned with foreign capital outflows from Brazilian risk assets during the week.
Serving as a structural counterweight, the US dollar appreciated against the Brazilian Real. The DOLX11 ETF traded in positive territory, closing the week up +0.32%. During the period, the commercial dollar traded around the R$ 5.0840 range, playing its role as a safe haven amid domestic institutional caution and declining prices for Brazilian exported commodities.
Crypto Assets Landscape
Unlike the Brazilian equity market, the cryptocurrency ecosystem demonstrated resilience during the first week of August 2026, with its price dynamics correlated with gains in US tech equities (such as the Nasdaq index).
-
Bitcoin (BTC): Supported by US non-farm payroll data and easing tensions in the Strait of Hormuz (which reduced oil-driven inflation fears), Bitcoin returned to trade above its 200-week simple moving average. The asset traded firmly in the $64,000 to $65,000 region. Reports pointed to approximately $745 million in net daily inflows into global crypto ETFs during the week.
-
Ethereum (ETH) and Solana (SOL): Ethereum maintained support above $1,900, with prices circulating close to $1,915, displaying directional stability and minor weekly gains. Solana stood alongside other altcoins (such as BNB and Dogecoin) that also posted positive weekly closes, benefiting from an external macroeconomic environment that was slightly more favorable for global risk assets, helping limit losses for investors with diversified exposure beyond the Brazilian capital market.
