The Global Debt Report examines sovereign and corporate debt markets, providing insights into current market conditions and associated policy considerations, including possible financial stability risks. This first edition consolidates the Sovereign Borrowing Outlook, previously a separate OECD publication, and introduces new chapters on corporate bond markets and sustainable bonds. Chapter 1 provides an overview of sovereign borrowing globally and an outlook for OECD countries, with a focus on the impact of recent developments in funding conditions and changes to the investor base. Chapter 2 explores global corporate bond market dynamics, build-up of risks and vulnerabilities and the impact of a changing macrofinancial landscape. Chapter 3 looks at trends in global sustainable bond markets and discusses policy considerations such as the sustainability premium, the roles of service providers and market liquidity.
