The OECD Sovereign Borrowing Outlook 2017 reports that despite high sovereign debt burdens, the overall central government marketable debt is projected to increase to USD 42.2 trillion, with a slight decline in the debt-to-GDP ratio due to expected economic growth. It highlights the impact of ultra-low interest rates, resulting in significantly reduced borrowing costs and an increase in long-term financing strategies, while also noting a rise in issuance of negative-yielding debt and index-linked bonds. Moving forward, the document emphasizes the need for coordination among policymakers to navigate the challenges posed by monetary and fiscal policy uncertainties.
