Fitch Maintains AA- Rating for Korea

Fitch has maintained its sovereign credit rating for Korea at AA-, the fourth-highest level.

In a report issued Thursday, the global credit rating agency said its outlook for Korea is "stable," citing "[South Korea's] robust external finances and a solid macroeconomic performance compared with peers."

However, it warned of several challenges facing the country, like "geopolitical risk from the relationship with North Korea, and longer-run challenges of rapid population [aging] and low productivity."

The agency projected Korea's annual growth this year and next of 2.5 percent.
