Eurozone debt crisis and bond yields convergence: evidence from the new EU countries

The present article examines 10-year bond yields convergence between each of the new EU countries and Germany, including a structural break that embodies the effects of the current sovereign debt crisis in the Eurozone. The analysis is based on a new definition of bond yields convergence that can be interpreted either as strong or weak monetary policy convergence, depending on whether the conditions of uncovered interest-rate parity and ex-ante purchasing power parity hold or are violated, respectively. The empirical results provide evidence of either strong or weak monetary policy convergence to Germany only for five new countries, namely Croatia, the Czech Republic, Lithuania, Romania and Slovakia. In contrast, for the rest of the new EU countries the empirical evidence suggests lack of monetary policy convergence to Germany. The latter result could be probably explained by the increased risk premia in these countries, as a result of the Eurozone sovereign debt crisis.
