In traditional bond markets, sovereign bonds provide benchmarks and serve as catalysts for the corporate bond market development. Contrary to the usual sequence of bond market development, sovereign issuers are latecomers to sustainable bond markets. Yet, our empirical study finds that sovereign green bond issuance can have quantitative and qualitative benefits for the development of private sustainable bond markets. Our results suggest that both the number and the size of corporate green bond issuance increase more in a jurisdiction after the sovereign debut. The results are more pronounced in countries with stronger climate policies. Sovereign green bond issuance also improves the quality of green verification standards in the corporate bond market more generally, consistent with the aim of fostering third-party reviews and promoting best practice in green reporting and verification. Finally, our work provides evidence that the sovereign debut increases liquidity and diminishes yield spreads of corporate green bonds in the same jurisdiction.

The crisis highlighted the importance of debt management in containing debt-related risks and the associated impact on debt markets. The impact of the crisis on debt levels, and the consequent implications for fiscal consolidation, has been the subject of much discussion and analysis. However, there has been relatively less focus on the issue of how that debt should be managed, including how its composition should be structured so as to mitigate key risk exposures, and its implications for debt market functioning. That task proved significantly complex and challenging through the crisis, particularly in advanced economies, with additional dimensions of risk revealed.

Sovereign investment grade status is often associated with lower spreads in international markets. Using a panel framework for 35 emerging markets between 1997 and 2010, thispaper finds that investment grade status reduces spreads by 36 percent, above and beyond what is implied by macroeconomic fundamentals. This compares to a 5-10 percent reduction in spreads following upgrades within the investment grade asset class, and no impact formovements within the speculative grade asset class, ceteris paribus. While global financial conditions play a central role in determining spreads, market sentiment improves with lower external public debt to GDP levels and higher domestic growth rates.

This paper surveys the literature on sovereign debt from the perspective of understanding how sovereign debt differs from privately issue debt, and why sovereign debt is deemed safe in some countries but risky in others. The answers relate to the unique power of the sovereign. One the one hand, a sovereign has the power to tax, making debt relatively safe; on the other, it also has control over its territory and most of its assets, making debt enforcement difficult. The paper discusses debt contracts and the sovereign debt market, sovereign debt restructurings, and the empirical and theoretical literatures on the costs and causes of defaults. It describes the adverse impact of sovereign default risk on the issuing countries and what explains this impact. The survey concludes with a discussion of policy options to reduce sovereign risk, including fiscal frameworks that act as commitment devices, state-contingent debt, and independent and credible monetary policy.

The OECD Sovereign Borrowing Outlook provides regular updates on trends and developments associated with sovereign borrowing requirements, funding strategies, market infrastructure and debt levels from the perspective of public debt managers.

The COVID-19 pandemic has brought the relationship between sovereigns and banks—the so-called sovereign-bank nexus—in emerging market economies to the fore as bank holdings of domestic sovereign debt have surged. This paper examines the empirical relevance of this nexus to assess how it could amplify macro-financial stability risks. The findings show that an increase in sovereign credit risk can adversely affect banks’ balance sheets and credit supply, especially in countries with less-well-capitalized banking systems. Sovereign distress can also impact banks indirectly through the nonfinancial corporate sector by constraining their funding and reducing their capital expenditure. Notably, the effects on banks and corporates are strongly nonlinear in the size of the sovereign distress.

Sovereign debt is necessary for states to function, yet its impact on human rights is underexplored. Bantekas and Lumina gather experts to conclude that imposing structural adjustment programmes exacerbates debt, injures the entrenched rights of peoples and their state's economic sovereignty, and worsens the borrower's economic situation.

The volume contains articles based on presentations given at a conference hosted by the Institute for Law and Finance of Goethe University on October 27, 2011. Collective action clauses are an example of the typical dichotomy of financial regulation: While the problems are economic in nature, the solutions need to be implemented by law. The Institute for Law and Finance strives to bring together law and finance in order to foster a better mutual understanding of both disciplines and to improve the regulation of financial markets. Thus, the organizers are particularly pleased that eminent experts from the fields of law and finance agreed to participate in the event and to share their views on and experiences with collective action clauses. The presentations given at the conference have been updated in 2012 to reflect recent developments.

Recent events have shown that sovereigns, just like banks, can be subject to runs, highlighting the importance of the investor base for their liabilities. This paper proposes a methodology for compiling internationally comparable estimates of investor holdings of sovereign debt. Based on this methodology, it introduces a dataset for 24 major advanced economies that can be used to track US$42 trillion of sovereign debt holdings on a quarterly basis over 2004-11. While recent outflows from euro periphery countries have received wide attention, most sovereign borrowers have continued to increase reliance on foreign investors. This may have helped reduce borrowing costs, but it can imply higher refinancing risks going forward. Meanwhile, advanced economy banks’ exposure to their own government debt has begun to increase across the board after the global financial crisis, strengthening sovereign-bank linkages. In light of these risks, the paper proposes a framework—sovereign funding shock scenarios (FSS)—to conduct forward-looking analysis to assess sovereigns’ vulnerability to sudden investor outflows, which can be used along with standard debt sustainability analyses (DSA). It also introduces two risk indices—investor base risk index (IRI) and foreign investor position index (FIPI)—to assess sovereigns’ vulnerability to shifts in investor behavior.

We analyze the relationship between global and country-specific factors and emerging market debt spreads from three different angles. First, we aim to disentangle the effect of global and country-specific developments, and find that while both country-specific and global developments are important in the long-run, global factors are main determinants of spreads in the short-run. Second, we investigate whether and how the strength of fundamentals is related to the sensitivity of spreads to global factors. Countries with stronger fundamentals tend to have lower sensitivity to changes in global risk aversion. Third, we decompose changes in spreads and analyze the behavior of explained and unexplained components over different periods. To do so, we break down fitted changes in spreads into the contribution of country-specific and global factors, as well as decompose changes in the residual into the correction of initial misalignment and an increase/decrease in misalignment. We find that changes in spreads follow periods of tightening/widening, which are well-explained by the model; and the dynamics of the components of the unexplained residual follow all the major developments that impact market sentiment. In particular, we find that in the periods of severe marketstress, such as during the intensive phase of the Eurozone debt crisis, global factors tend to drive changes in the spreads and the misalignment tends to increase in magnitude and its relative share in actual spreads.
