People walk past a Caixa Economica Federal bank in downtown Rio de Janeiro on Thursday. Economic activity in Brazil dropped sharply in June as the World Cup soccer tournament shut down shops and factories across the country, adding to signs that Latin America’s largest economy has slipped into recession.
