Abstrakt: This thesis provides evidence of how macroeconomic
surprises, constructed as deviations from market expectations, impact daily spread changes of Czech, Polish and Hungarian (CEEC-3) government bonds
and sovereign credit default swaps. Firstly, we carried out series of event studies that inspect the spreads’ reactions to the announcements. Subsequently,
we employed the general - to - specific modeling approach and arrived at thirty GARCH - type models that consider surprises ’ impact on both conditional mean and variance. We have found significant impacts on the mean, yet in terms of magnitude, the impact of macroeconomic surprises has not been superior
to that of broad financial factors. The impact on spreads’ volatility app ears more consequential though it lacks a clear pattern: Both good and bad news
have been found to affect the volatility in either direction. Our findings suggest that with respect to macroeconomic news, daily changes of the bond spreads are driven rather by inflation expectations than by credit risk considerations.
Foreign news proxied by the German surprises seems to affect the CEEC - 3 bond spreads mainly through
the risk-free proxy – the German Bund yield
. Contrary to studies using low- frequency macroeconomic data, we have found no evidence for the “wake - up call” hypothesis
