摘要:This paper studies the effect on credit spreads from the various “unconventional” monetary policies, conventional monetary policy, and fiscal policies introduced during the 2007–09 financial crisis period. Based on credit-spread changes on policy announcement date, policy implementation date, and policy implementation size over time, the paper concludes that the multitude of “unconventional” monetary policies were modestly effective in reducing market spreads; fiscal policy announcements did not reduce credit spreads; and increases in the Taylor-rule residual (a measure of conventional monetary policy) is associated with an increase in credit spreads. Credit spreads are measured in this paper by LIBOR-OIS spread, repo-OIS spread, and corporate-Treasury bond spread.
