The market in Mexican corporate bonds – ‘Cebures’ – had historically been limited in size with little foreign investor interest. The high local borrowing costs deterred local corporates from raising money in the peso market.
This meant large entities, such as Pemex, raised the bulk of their term debt in the form of international dollar issues. For international investors, there was little incentive to invest in Cebures as they did not figure in international corporate bond indices.
