The international rating agency has also affirmed Lithuania's short-term foreign currency rating at F1 and the country ceiling at AAA.
"Lithuania's ratings are supported by prudent fiscal management, reflected in modest fiscal deficits and a declining debt burden, as well as institutional strengths and a credible policy framework that come with EU and eurozone membership," Fitch Ratings said in a press release.
"However, external finances are weaker, and the rating remains constrained by structural bottlenecks that weigh on the country's progress in convergence towards income levels of higher-rated peers," it added.
The agency expects that Lithuania's economy will expand by 3.2 percent this year and forecasts average GDP growth of 2.7 percent in the next two years.
Lithuania is rated at A- by Standard & Poor's and at A3 by Moody's. Both agencies' outlook for the country's long-term rating is stable.
