Sovereign ESG Methodology for Fixed Income Investment

This technical report outlines the Sovereign ESG Methodology established in 2019, which evaluates countries' sustainability performance to support sovereign bond investment decisions. The framework aims to identify countries with strong ESG practices while avoiding biases against developing nations by contextualizing performance within their development stages. The report discusses the integration of ESG factors into sovereign bond evaluations, emphasizing the relationship between ESG performance and sovereign credit risk. It details the challenges in establishing universal sustainability standards and the income bias present in ESG ratings. The methodology incorporates a quantitative scoring model adjusted for GDP per capita and a qualitative assessment of sustainability momentum. This dual approach seeks to provide a comprehensive analysis of countries' ESG performance, addressing the limitations of existing data and ensuring a more nuanced understanding of sustainability risks and opportunities across different income groups.
