US rating faces cut in 2013 if no credible plan: Fitch

The country's debt-to-GDP ratio is expected to increase over the medium term: Fitch

Fitch Ratings reiterated on Thursday it would cut its sovereign credit rating for the United States next year if Washington cannot come to grips with its deficits and create a "credible" fiscal consolidation plan.

"The United States is the only country (of four major AAA-rated countries) which does not have a credible fiscal consolidation plan," and its debt-to-GDP ratio is expected to increase over the medium term, said Ed Parker, sovereign ratings analyst, speaking at a Fitch conference in New York.
