Harald Kinateder; Niklas Wagner: Quantitative Easing, Unobservables, and Fundamentals in the Pricing of EMU Sovereign Debt

We study the determinants of changes in EMU sovereign bond yield spreads using a comprehensive set of observable explanatory variables including unconventional ECB monetary policy and fundamentals, both at a country-specific and a common level. We thereby employ a novel approach by jointly considering observable as well as additional unobservable time-varying factors. Our results reveal that unconventional monetary policy indeed significantly affects the pricing of EMU sovereign debt. Aggregate market liquidity has at least as much impact on yield spread changes as country-specific bond liquidity. Concerning unobservables, we find that a systematic risk premium together with country-specific turmoil factors, which explain divergence between turmoil and non-turmoil countries, explain about two-thirds of the variation in yield spread changes. A substantial underpricing of unobservable risk factors before the European sovereign debt crisis is further revealed. We conclude that fixed-income management should account for unobservable credit risk factors.
