NEW YORK, Sept 3 (Reuters) - Fitch Ratings on Thursday lowered the outlook on Portugal's long-term foreign currency ratings to negative from stable, citing worry about the impact of the global crisis on public finances given its weak economy and high levels of debt.
The agency rates Portugal's long-term foreign currency Issuer Default Rating at AA, or third-highest investment grade.
"Portugal has had some success in implementing structural and fiscal reforms since 2005, but the country remains structurally weak relative to peers," said analyst Douglas Renwick in a statement. (Reporting by Ciara Linnane; Editing by James Dalgleish)
