The Link between Eurozone Sovereign  Debt and CDS Prices

Abstract

We perform a theoretical and empirical analysis of the relationship between the price of Eurozone sovereign-linked credit default swaps (CDS) and the same sovereign bond markets during the Eurozone debt crisis of 2009-2011. We first present a simple model which establishes the no-arbitrage relationship between CDS and bond yield spreads. We then test this relationship empirically and explain why the market may deviate from it. Reasons include the different currencies of denomination of market-standard CDS and their reference obligations. We also examine whether CDS spread cause changes in bond spreads, and vice-versa, in a Granger sense. We find evidence for a Granger causal relationship with a one day lag from CDS to bonds for Greece and Spain, the reverse relationship for France and Italy and a feedback relationship for Ireland and Portugal.

Collateral Crises

Abstract

Short-term collateralized debt, private money, is efficient if agents are willing to lend without producing costly information about the collateral backing the debt. When the economy relies on such informationally-insensitive debt, firms with low quality collateral can borrow, generating a credit boom and an increase in output. Financial fragility builds up over time as information about counterparties decays. A crisis occurs when a small shock causes agents to suddenly have incentives to produce information, leading to a decline in output. A social planner would produce more information than private agents, but would not always want to eliminate fragility.
