Brazilian banks sent the Ibovespa to the biggest slide in the world after Banco do Brasil SA joined Itau Unibanco Holding SA in allocating more money for soured loans. The real approached the lowest level in 12 years.
Financial shares in the MSCI Brazil Index sank to a six-year low on speculation other lenders will be forced to bolster so-called provisions. The stock benchmark dropped for a third day, while the real extended this year’s plunge to 24 percent. Swap rates, a gauge of expectations for borrowing costs, rose.
Lenders have suffered from a slowdown in consumer purchases as financing gets more expensive with interest rates at a nine-year high. The selloff in banks has intensified since May on concern that President Dilma Rousseff’s decision to boost taxes on the industry’s profits will erode earnings.
