This article examines the euro area corporate bond market, in particular its development since the introduction of the euro. This market, that is to say, debt securities issued by non-financial corporations, non-monetary financial corporations and monetary financial institutions, is economically important, as it contributes to the allocation of funds to their most profitable uses. The euro area corporate bond market has grown rapidly since the introduction of the euro. Empirical analysis using regression techniques suggests that this growth can be explained by developments in economic activity, the costs of issuance and M&A-related activity. The latter reflects financing needs related to corporate restructuring, which in turn appears to be triggered partly by the introduction of the euro. The results also suggest that the introduction of the single currency had a direct and permanent effect on debt securities issued by non-monetary financial corporations. However, the use of corporate bonds at the euro area level is not uniform across countries. Country-specific factors continue to matter, despite the fact that financial markets are gradually becoming more integrated. To reap the full benefits of integration, public authorities and market practitioners are implementing a number of EU initiatives.
