SAO PAULO, May 25 (Reuters) - Brazil's second-largest private-sector bank, Bradesco (BBDC4.SA)(BBD.N), expects default rates to peak in June, earlier than previously forecast, because of an improved view on credit trends, a bank vice president said in an interview on Monday.

Most of the improvement has taken place in consumer lending and in credit to small- and medium-sized companies, said Bradesco Vice President Norberto Barbedo. The bank previously expected default rates to peak in August or September.

"We have a slightly better view for default rates now," Barbedo told Reuters.
