Systemic Risk Management in Financial Networks with Credit Default Swaps
We study insolvency cascades in an interbank system when banks are allowed to insure their loans with credit default swaps (CDS) sold by other banks. We show that, by properly shifting financial exposures from one institution to another, a CDS market can be designed to rewire the network of interbank exposures in a way that makes it more resilient to insolvency cascades. A regulator can use inf...
متن کاملCredit Default Swaps networks and systemic risk
Credit Default Swaps (CDS) spreads should reflect default risk of the underlying corporate debt. Actually, it has been recognized that CDS spread time series did not anticipate but only followed the increasing risk of default before the financial crisis. In principle, the network of correlations among CDS spread time series could at least display some form of structural change to be used as an ...
متن کاملDefault Ambiguity: Credit Default Swaps Create New Systemic Risks in Financial Networks∗
We study financial networks and reveal a new kind of systemic risk arising from what we call default ambiguity, i.e., a situation where it is impossible to decide which banks are in default. Specifically, we study the clearing problem: given a network of banks interconnected by financial contracts, determine which banks are in default and what percentage of their liabilities they can pay. Prior...
متن کاملCredit Default Swaps and Risk-Shifting
Credit default swaps (CDSs) are thought to ease borrowing by protecting lenders against default. This paper develops a model of the demand for CDS when borrowers choose the riskiness of investment and verification is imperfect. The model shows that CDSs may lead to risk-shifting, increasing the probability of default. Our model provides new insights on the role of CDS during the recent financia...
متن کاملFinding Clearing Payments in Financial Networks with Credit Default Swaps is PPAD-complete
We consider the problem of clearing a system of interconnected banks that have been exposed to a shock on their assets. Eisenberg and Noe (2001) showed that when banks can only enter into simple debt contracts with each other, then a clearing vector of payments can be computed in polynomial time. In this paper, we show that the situation changes radically when banks can also enter into credit d...
