NEW YORK (Standard&Poor's) Oct. 24, 2006--Standard&Poor's Ratings Services said today that it assigned its 'A' long-term local currency rating to the Bonos de Desarrollo (Bondes D) issued today by the United Mexican States (BBB/Stable/A-3 foreign, A/Stable/A-1 local currency sovereign credit ratings). The bonds, which are expected to raise Mexican peso (MNP) 2 billion, mature in November 2036. "The new 30-year bond is an important extension of the Mexican sovereign yield curve," said Standard&Poor's credit analyst Joydeep Mukherji. "The availability of more long-term funding in local currency, especially at fixed interest rates, improves the profile of sovereign debt, making the government less vulnerable to a change in the exchange rate or international interest rates," he
