MEXICO CITY (Standard&Poor's) Sept. 30, 2008--Standard&Poor's Ratings Services revised its outlook on National Commercial Bank Jamaica Ltd. (NCB) to negative from stable; the counterparty credit ratings were affirmed at 'B/B'. "The outlook revision reflects our opinion that, although the bank's performance continues to be adequate for the current 'B' rating, there are important economic and liquidity pressures from both local and global markets that could have an impact upon the bank's finances over the next 12 months. We believe that the bank faces a less benign operational environment, with compressing margins, various exposures to the weaker pricing of Jamaican sovereign bonds, tighter liquidity in the international markets, and high inflation," said Standard&Poor's credit analyst
