Bolsa Mexicana de Valores is in preliminalry talks to sell a minority stake to Chicago-based derivatives exchange operator CME Group.
The Mexican exchange has stressed the talks may not lead to any deal and CME Group has yet to comment. Local press reports claim the Chicago operator is interested in a five per cent stake.
CME already has interests in Latin America, owning a five per cent stake in Brazil's BM&F Bovespa, which in turn holds a two per cent stake in the Chicago outfit.
Earlier this month the Brazilian exchange got the green-light to offer US traders access to stocks on the Ibovespa index through CME Group's electronic trading network.
