This paper examines the financial stress interconnectedness among Greece, Ireland, Italy, Portugal, and Spain (GIIPS) economies and Germany. Based on market-level financial stress indices, we examine the stress transmission process as well as the causal network relationships in banking sector, bond, money, and stock markets. The period under investigation, 2001–2013, allows to test the effects of the 2007–2009 financial crisis as well as the subsequent European sovereign crisis. Using two alternative techniques for connectedness analysis, our evidence suggests that the peripheral economies of Italy and Spain play a highly significant role in the stress transmission in all markets, especially in the cases of banks and equity markets. Moreover, we visualize our results using network analysis. Contrary to common wisdom, Portugal, Ireland, and mainly Greece do not seem to have an important role in amplifying stress levels.
