Speaking at Anadolu Agency's Editor's Desk, Muezzinoglu said the Fitch move was not an "economic" but a "political" one.

"Today, the Turkish economy multiplies Greece by 100 with its dynamics, export and production. But it [Greece] will never suffer rating downgrades, but upgrades.

"Why? Because the [Fitch] move is not economic, but political," Muezzinoglu said.

On Jan. 28, Fitch lowered Turkey's credit rating to "BB+", from "BBB-" with a stable outlook.

"Political and security developments have undermined economic performance and institutional independence," Fitch said in a statement. "High-profile terrorist attacks have continued, damaging consumer confidence and the tourism sector,” it claimed.

Although the political environment "may stabilize," security challenges remain, Fitch added.
