TOKYO, Feb 21 (Reuters) - Moody's Ratings said on Friday

it has downgraded its rating of Nissan Motor ( NSANF ) credit by

one notch to junk status, citing a weak and worsening outlook

for the Japanese automaker's credit profile.

The credit-rating firm cut Nissan's ( NSANF ) senior unsecured rating

to Ba1 from Baa3 and maintained its negative outlook.

In a report, senior analyst Dean Enjo cited "risks

associated with the implementation of its new restructuring

plan, the renewal of its aging product range and global trade

policies".

Last month, S&P Global Ratings revised the automaker's

credit outlook to negative and stable and affirmed its BB+

rating.

Last week, Nissan ( NSANF ) ended talks with Honda Motor ( HMC ) for

a possible merger, pitching it deeper into uncertainty.
