Abstract
This dissertation contains a series of essays, three in total, which examine the determinants of integration of Islamic and conventional financial markets. Academic and commercial interest in Islamic finance has increased in recent years, meaning that it is commonly seen as a reasonable alternative to mainstream finance. However, it is notable that growing awareness of Islamic finance has emerged alongside several relevant concerns surrounding the poor performance of Shariah-compliant indices. The limitations include minimal access to risk management tools, low regulatory standards in Islamic finance, and a suboptimal governance framework.
With the large expansion of Islamic finance in recent years, Sukuk (Islamic bonds), which are the Shariah-compliant substitute to conventional bonds, are becoming more prominent. Although numerous studies have examined the impact of global shocks on conventional bond spreads, little attention has been paid to explore the effect of global shocks on the Sukuk spreads. Therefore, the first study's objective was to examine the impact of factors affecting the conventional bond and Sukuk markets, including financial factors, economic policy uncertainty, US and EU macroeconomic news. Using an ordinary least squares approach, the results indicated that for regions and countries such as the GCC (Gulf Cooperation Council), Malaysia, Indonesia, Turkey, and Singapore, global shocks play a vital role in explaining Sukuk spreads. Furthermore, employing a matched sample featuring firms from these regions and countries revealed that European and US macroeconomic announcements and economic policy uncertainty have a significantly greater impact on Sukuk spreads than on conventional bond spreads.
The second study builds on the directional spillovers from Sukuk markets to Shariah-compliant equity markets and vice versa. The directions and magnitudes of spillovers are quite disperse among different countries and Islamic equity markets. Novel to the literature, we find that the Islamic equity markets' profitability and liquidity positions are highly influential on the magnitude of spillovers. We create a matched sample for 38 firms that issued both Sukuk and Islamic equities. Implementing similar spillover models, we indicate that firms' firm-level profitability and liquidity positions are essential in modeling the spillovers' magnitude between Sukuk and equities.
Finally, the third study explores spillovers from regional and global equity markets to sectoral equity indices for several different regions/countries. First, we investigate sectoral equity return spillovers' connectedness and explore the different patterns and magnitudes of spillovers. Next, we look for the determinants of sectoral equity return spillovers. We find the regional and global markets spillovers on sector equity indices are highly dispersed across different markets. Novel to the literature, we examine the sectors' liquidity and financial positions and find that sector positions are highly influential in explaining the extent of the spillovers. Particularly, our exploration evidence that regional and global spillovers to specific sector equity markets jump significantly when a sector has higher debt and lower interest expense coverage. Similarly, higher profit margins of the sector make it less vulnerable to global and regional shocks. We also find market capitalization of the sectors inversely affects the spillovers' extent originating from global and regional markets.
