Fernando Golpas and Javier Solada were reviewing the financial reports of several Latin American governments. They noticed that the central governments of many Latin American countries such as Argentina, Chile, Peru, and Ecuador had recently been issuing sovereign debt. This sparked a discussion between the two analysts about sovereign debt ratings. During their discussion they made the following statements: Golpas: The rating agencies, such as Moody’s, generally assign two ratings to sovereign debt. One is a local currency debt rating and the other is a foreign currency debt rating. The reason for the two ratings is that the default frequency has been greater on local currency denominated debt. Solada: If a central government is willing to raise taxes and control its internal financial system, it should be able to generate sufficient local currency to meet its local currency obligation. That is why the rating on local currency denominated debt is generally higher than the rating on foreign currency denominated debt. Are the statements made by Golpas and Solada regarding sovereign debt ratings correct Golpas Solada ()①A. Correct Correct ②B. IncorrectCorrect ③C. IncorrectIncorrect
