Fitch Ratings said yesterday that it has cut its outlook on the UK’s sovereign debt ratings to “negative” from “stable” due to possible unforeseenfuture economic fallout stemming from the eurozone debt crisis.

But the agency affirmed the UK’s long-term foreign currency issuer default rating at AAA.

A ratings outlook indicates the potential direction in which a rating may be changed over the next six months to two years. A “negative” outlook suggests a credit rating may eventually be lowered.

“The revision of the rating outlook to ‘negative’ from ‘stable’ reflects the very limited fiscal space to absorb further adverse economic shocks in light of such elevated debt levels and a potentially weaker-than-currently forecast economic recovery,” Fitch said yesterday in a statement.
