Spain and the European sovereign debt crisis

This paper presents empirical evidence indicating that German and Spanish government bond yields are cointegrated. Thus, a stable long-term equilibrium relationship among these two variables seems to exist. However, there is also empirical evidence for the existence of a structural break in early 2009. Following Basse, Friedrich and v. d. Schulenburg (2011) we interpret this finding as an indication that financial markets started to see a higher sovereign credit risk in Spain. The structural break may even signal some fears about the return of exchange rate risk. Given that the break date is quite early; our empirical findings could be an indication that bond markets are at least partially efficient. (C) 2013 Elsevier B.V. All rights reserved.
