[EN] This paper introduces the Turkish lira (TL) corporate bond market and presents the estimations of corporate bond yield curve using the Nelson Siegel methodology. Results suggest that Nelson Siegel method performs a good fit for corporate bonds. Additionally, we focus on the impact of recent monetary policy induced shocks on the corporate yield curve in comparison with the sovereign yield curve. Event studies present evidence that the response of corporate bond yields to the monetary policy shocks might diverge from that of government bond yields in terms of magnitude or sometimes even direction.
