Brazil’s Ibovespa posts its fifth-biggest weekly fall since 1994
Brazil’s Ibovespa fell more than 18% in one week, its fifth-biggest weekly drop since the Real Plan began in 1994 and its steepest since March 2020.
The sell-off followed the re-election of President Luiz Inácio Lula da Silva, as investors reassessed the value of Brazilian shares.
On Monday, the index fell nearly 14% in one session, triggering a temporary trading halt called a circuit breaker.
By Friday, it had fallen for five straight sessions, and the week’s losses had cut listed companies’ combined market value by R$873 billion.
October’s decline reached 9.75%, but the index was still up 4.22% for the year.
Unlike earlier historic falls linked to global crises, this drop was driven mainly by domestic politics, and the figures given do not say what happens next.
