International credit rating agency Moody's Investor Service lowered Government of Turkey's long-term issue rating and Turkey's foreign currency bond ceiling to B1. Since Turkish Airlines' credit rating aligned to the foreign currency bond ceiling, Moody's has downgraded the corporate family ratings of Turkish Airlines to B1 negative from Ba3 negative.

Along with this, issue ratings of Turkish Airlines' Enhanced Equipment Trust Certificates (EETCs), which have been issued in 2015, have also been reviewed, and as a result, they were lowered to Ba3 from Ba1.
