UBS and Credit Suisse are among the banks leading the $2.3bn (€1.6bn) sale of Bovespa, the São Paulo Stock Exchange, which could potentially become Brazil's largest initial public offering.

The two banks alongside Brazilian firms Banco Itau and Banco Bradesco, are bookrunners of the exchange's R$4.3bn ($2.3bn) offer in which shares are being sold at between R$15.50 and R$18.50.
