Abstract

This article analyses the factors that seem to play an important role in determining the cost of sovereign debt. Specifically, we evaluate to what extent transparency, the level of corruption, citizens’ trust in politicians and credit ratings affect interest rates. For that purpose, we create a transparency index matching the 2007 Organisation for Economic Co-operation and Development/World Bank Budgeting Database items with the Organisation for Economic Co-operation and Development Best Practices for Budget Transparency sections. We also check our assumptions with the International Budget Partnership’s Open Budget Index and with a non-linear transformation of our index. Furthermore, we use several control variables for a sample of 103 countries in the year 2008. Our results show that better fiscal transparency, political trust and credit ratings are connected with a lower cost of sovereign debt. Finally, as expected, higher corruption, budget deficits, current account deficits and unemployment make sovereign interest rates increase.

Points for practitioners

The key implications for professionals working in public management and administration are twofold. First, despite the criticism raised by credit ratings, it is clear that poorer ratings are connected with higher financing costs for governments. Therefore, governments should enhance those indicators that impact the credit rating of their sovereign debt. Second, governments should seek to be more transparent, since transparency reduces uncertainty about the degree of cheating, improves decision-making and therefore decreases the cost of debt. Transparency reduces information asymmetries between governments and financial markets, which, in turn, diminishes the spread requested by investors.
