The state-owned oil (Pemex) and electric power (Federal Electricity Commission) companies face no competition. The private virtual monopolies in telecommunications (Telmex), television (Televisa), cement (Cemex), bread and tortilla manufacturing (Bimbo and Maseca, respectively), banking (Banamex/Citigroup and Bancomer/Banco de Bilbao) may face competition abroad, but not at home.
