Abstract: Is the pricing of sovereign risk linear during bearish episodes? Or can initial shocks on economic fundamentals be exacerbated by endogenous factors that create nonlinearities? We test for nonlinearities in the sovereign bond market of European peripheral countries during the debt crisis and explain them. Our estimates based on a panel smooth threshold regression model during January 2006 to September 2012 show four main findings: 1) Peripheral sovereign spreads are subject to significant nonlinear dynamics. 2) The deterioration of market conditions for financial names changes the way investors price risk of the sovereigns. 3) The spreads of European peripheral countries have been priced above their historical values, given fundamentals, because of amplification effects. 4) Two CDS indices on financial names unambiguously stand out as leading drivers of these amplification effects.
