A Structural Model of Sovereign Credit and Bank Risk

 October 25 , 3:00 - 4:30, Hill Center 552
Abstract: In the recent past, sovereign credit took center stage in the market's perception of risk.  This occurred not only because certain countries emerged as potential debtors in default, but also because some major economies showed signs of fundamental strain in their public finances.  The financial market effects of potential sovereign default and ensuing bank weakness and contagion, and the undermined capability of governments to sustain the Keynesian support for their vulnerable economies demonstrate the paramount importance of accurate and rigorous risk measurement of sovereign entities and financial institutions. In this presentation we make an overview of a model designed for this task.  It builds on established credit risk methodology for corporate entities known from the seminal work of Merton, and takes a new direction to adapt the default option argument to a sovereign debt setting. The proposed model caters to economic intuition and resorts to explicit measures of macro economic activity as its buildings blocks.  We differentiate sovereign entities into three distinct categories, and adapt our general arguments to each of these groups. Furthermore, we pursue the connection between the viability of sovereign entities and the viability of the jurisdictional financial institution.  Finally, we juxtapose the model results with metrics of credit risk from the financial markets, as a reality check of the success of approach.
