The volatility spillover among a country’s foreign exchange, bond, and stock markets: a multivariate garch analysis

Kubilay, Mustafa Murat
The purpose of this study is to examine the volatility spillover among a country’s foreign exchange, bond and stock markets and the volatility transmission from the global bond, stock and commodity markets to these local financial markets. The sample for the study includes data from both emerging and developed economies in the time period between 2004 and 2011. A multivariate GARCH methodology with the BEKK representation is applied for the local financial markets and global variables are included as exogenous variables into the model. The volatility integration of the financial markets of the emerging economies is stronger compared to the integration of the developed economies. Global variables have a spillover effect on the developed markets only after the global financial crisis, whereas they significantly affect the volatility in emerging markets for both the pre- and post-crisis period. North American countries in the sample, U.S. and Mexico, have low local volatility integration in the pre-crisis era and the integration rises in the post-crisis period. Moreover, they are more open to the internal and global short-term shocks in the post-crisis period. Germany and Turkey are the representatives of the EMEA (Europe, Middle East and Africa) region and they have high local market integration and are open to global shocks for both sub-periods. Far Eastern markets, Japan and Korea, also have high local market integration and their vulnerability to the global effects is large and getting larger for the post-crisis period. The most important limitation of this thesis is the difficulty of reaching sharp generalizations due to the small number of countries analyzed. This limitation can be addressed by the inclusion of a larger number of geographically dispersed countries. The most noteworthy originality of this study is the addition of the exogenous global variables for modeling volatility spillovers. Furthermore, comparison of results for emerging versus developed markets and the pre- versus post-crisis periods is another contribution of this study to the existing literature. The findings of this study can be used by investors interested in assessing the risks of investing internationally.

Yücesan, Esin; Rhoades, Seza; Department of Business Administration (2004)
The objective of the study is to analyze the effects of two breakpoints on the relationships of Istanbul Stock Exchange with the European stock markets and on the relationships among these European stock markets to increase the economic integration. The breakpoints are the execution of the Customs Union Agreement of Turkey with the European Union in 1/1/1996 and the introduction of the Euro in 1/1/1999. While both breakpoints have effects on Turkey̕s economic relations, the European Union countries are expe...
The Relationship Between Disaggregated Country Risk Ratings and Stock Market Movements: An ARDL Approach
Sarı, Ramazan; Hammoudeh, Shawkat (Informa UK Limited, 2013-01-01)
We examine the relationships between disaggregated country risk ratings and stock market movements in Turkey, using the autoregressive distributed lag approach. The long- and short-run relationships between stock market movements and political risk, financial risk, and economic risk components of country risk ratings are investigated. The presence of a long-run relationship between Turkey's risk ratings and stock market movements is confirmed. In the long run, Turkey's three economic, financial, and politic...
A market model for pricing inflation indexed bonds with jumps incorporation
Güney, İbrahim Ethem; Hayfavi, Azize; Department of Financial Mathematics (2008)
Protection against inflation is an essential part of the today's financial markets, particularly in high-inflation economies. Hence, nowadays inflation indexed instruments are being increasingly popular in the world financial markets. In this thesis, we focus on pricing of the inflation-indexed bonds which are the unique inflation-indexed instruments traded in the Turkish bond market. Firstly, we review the Jarrow-Yildirim model which deals with pricing of the inflation-indexed instruments within the HJM fr...
Modeling co-movements among financial markets: applications of multivariate autoregressive conditional heteroscedasticity with smooth transitions in conditional correlations
Öztek, Mehmet Fatih; Öcal, Nadir; Department of Economics (2013)
The main purpose of this thesis is to assess the potential of emerging stock markets and commodity markets in attracting the attention of international investors who utilize various portfolio diversification strategies to reduce the cumulative risk of their portfolio. A successful portfolio diversification strategy requires low correlation among financial markets. However, it is now well documented that the correlations among financial markets in developed countries are very high and hence the benefits of i...
Static hedging strategies for barrier options and their robustness to model risk
Kaya, Orçun; Hayfavi, Azize; Department of Financial Mathematics (2007)
With the rapid increase in the usage of barrier options on the OTC markets, pricing and especially hedging of these exotic instruments became an important field of research. This paper aims to explain, apply and compare current methods used for pricing and hedging barrier options with a simulation approach. An overview of most popular methods for pricing and hedging is presented in the first part, followed by application of these pricing methods and comparing the performances of different dynamic and static...
