Speaker : Lei Zhao at ESCP Europe, member of LABEX ReFi
The moral hazard problem caused by the implicit public subsidies extended to too-big-to-fail (TBTF) institutions has long been posing a serious threat to the stability of the financial system. Implicit government guarantees (IGG) stem from the expectation that the government will lend support to troubled financial firms deemed to be of systemic importance. To measure such guarantees, we exploit the price differential of CDS contracts written on debts with different seniorities. Our estimate of the annual implicit support enjoyed by the sample firms peaks at €175 billion in 2011. Subsidy at this level provides incentives for banks to grow larger and its variation over time deserves attention when investors make investment decisions or banks price their financial products.
In this talk, we will try to answer the following questions: (1) What is the magnitude of the implicit guarantees, both at bank level and also at aggregate level? (2) Are banks different from insurance companies in terms of the level of implicit support they obtain? (3) Does Eurozone have implications for IGG enjoyed by financial firms in the area? (4) What is the two-way feedback effect between IGG and sovereign credit risk?
