Standard and Poor’s (S&P), Moody’s and Fitch have been producing credit ratings for government bonds and corporate bonds. Changes in credit ratings affect the investors’ decisions and government cost of borrowing as well. 2008 global financial crisis is an important milestone for the credit rating agencies since during the crisis period high rated countries faced with deep economic fluctuations which decreased the creditworthiness of these agencies. This thesis investigates the relationship between sovereign bond spreads and rating changes during the post-crisis period for Turkey. We perform vector autoregression (VAR) model including Granger causality test and impulse response functions (IRFs) analysis to investigate the effects of rating changes on the Turkish government bond spreads from July 2007 to March 2013. We also perform event study analysis in order to capture the dynamic effects of rating changes on Turkish government bond spreads. We find some evidence that rating announcement are often anticipated by the market so investors take their position before announcement day which give us insignificant results in VAR estimates.

EXAMINATION OF BOND RISK PREMIA FROM THE BANKING PERSPECTIVE
Orhan, Selim; Danışoğlu, Seza; Department of Financial Mathematics (2022-5-10)
Banks are considered as the marginal and sophisticated investors of financial markets. This is evident in the Haddad and Sraer (2020) study that examines the US government bond excess returns. This study extends the Haddad/Sraer analysis to the Turkish government bond market. According to the forecasting results, exposure ratio provides explanatory power over bond excess returns, especially for longer maturities. On the other hand, output gap and industrial growth present strong in-sample forecasting power ...
The Effect of Margin Changes on Futures Market Volume and Trading
Danışoğlu, Seza (null; 2017-01-08)
Margins are performance bonds that are designed to protect market participants and the market as a whole against investor default. Academic interest in analyzing margins started in the late 1960s and the number of studies increased parallel to the growth of the derivatives markets. Studies on margins mostly focus on the margin regulations, impact of margin levels on trading activity and optimal margin rules. The aim of this study is to determine the impact of margin levels and margin changes on trading acti...
