S&P said Monday it raised the long-term credit rating for South Korea to AA from AA- with a stable outlook, the agency’s third-highest rating. This follows an upgrade to Aa2 from Moody’s Investors Service in December 2015, which marked the first time that South Korea received a third-highest ranking from a major ratings agency. Fitch Ratings ranks South Korea at AA-, the fourth-highest level.
