This paper analyses whether the introduction of capital requirements for bank government bond holdings increases financial stability by making the banking sector more resilient to sovereign debt crises. Using a theoretical model, we show that a sudden increase in sovereign default risk may lead...

In this study, we analyze the effects of sovereign credit rating reviews on national stock market performances in GIIPS and BRIC countries during the European Sovereign Debt Crisis of 2009-2013. Through an event study, we test the Null Hypothesis that cumulative abnormal returns on national...

European banks are exposed to a substantial amount of risky sovereign debt. “Missing capital” in the banking system resulting from the zero-risk weight exemption for European sovereign debt amplifies the co-movement between sovereign CDS spreads and facilitates cross-border crisis...

Euro area governments have committed to break the doom loop between banks and sovereigns. But policymakers disagree on how to treat sovereign exposures in bank regulation. Our contribution is to model endogenous sovereign portfolio reallocation by banks in response to regulatory reform....

Recent policy discussion includes the introduction of diversification requirements for sovereign bond portfolios of European banks. In this paper, we evaluate the possible effects of these constraints on risk and diversification in the sovereign bond portfolios of the major European banks....

Euro area governments have committed to break the doom loop between bank risk and sovereign risk. But policymakers have not reached consensus on whether and how to reform the regulatory treatment of banks' sovereign exposures. To inform policy discussions, this paper simulates portfolio...

We study the impact of changes in regulations and policy interventions on systemic risk among European sovereign entities measured as volatility spillovers in respective credit risk markets. Our unique intraday CDS dataset allows for precise measurement of the effectiveness of these events in a...
