Why Brazil’s Stocks and Funds Like the iShares MSCI Brazil ETF Are Crashing Today

Brazil's equity market sold off hard on October 26, 2026, with the iShares MSCI Brazil ETF (EWZ) dropping nearly 23% after incumbent Luiz Inacio Lula da Silva defeated conservative rival Flavio Bolsonaro in Sunday's presidential election.

The catalyst is political, not earnings-driven. Investors are pricing in economic uncertainty following a left-leaning victory, and the selloff reflects concern over potential political turmoil. Bolsonaro's contested election results have intensified that worry, with market participants pointing to the possibility of destabilizing actions similar to his father's 2023 coup attempt.

A near-23% single-session decline in a country ETF is a severe repricing. Interpretation: the magnitude suggests the market is assigning meaningful probability to a prolonged dispute over the result, not simply adjusting for a policy shift. Because EWZ is the broad Brazil benchmark, the move likely spans the large-cap names traders watch most, including NU, ITUB, PBR and PBR.A, though the source does not break out individual declines.

The key variable now is whether Bolsonaro's camp escalates its challenge to the result or concedes. That binary outcome will likely drive whether the selloff extends or stabilizes.
