Abstract: For the largest 55 German banks, we detect the presence of countercyclical yield seeking in the form of acquisition of high-yielding periphery bonds in the period from Q1 2008 to Q2 2011. This investment strategy is pursued by banks not subject to a bailout, banks characterised by high capitalisation, banks that rely on short-term wholesale funding, and trading banks. In the subsequent period up to 2014, these banks switched to a procyclical divestment strategy resulting in the sale of risky assets. Following the launch of the public sector purchase programme (PSPP) in 2015, a clear investment pattern can no longer be identified. Unlike existing evidence for banks domiciled in vulnerable countries, we find that the recourse to central bank finance is rather limited and does not affect the risk-taking behaviour of banks in a non-stressed country such as Germany. Yield-seeking strategies were predominantly pursued by strong banks in Germany. Thus, with respect to the increases in domestic sovereign holdings in vulnerable countries, we instead presume moral suasion and, for weakly capitalised banks, a kind of "hidden moral suasion" or "home-biased" gambling for resurrection to actively push the sovereign-bank nexus. These policies were flanked by an expansionary monetary policy and regulation with no capital adequacy requirements for euro area sovereign bonds.
