    Impact of Global Risk Factors on the Islamic Stock Market: New Evidence from Wavelet Analysis
    (Springer, 2024) Kazak, Hasan; Saiti, Buerhan; Kilic, Cueneyt; Akcan, Ahmet Tayfur; Karatas, Ali Rauf
    The emergence of Islamic finance as an alternative financial investment area and the increasing political and economic uncertainty around the world necessitated an examination of the relationship between these two factors. This study examines the impact of four important global uncertainty and risk indicators Global Economic Policy Uncertainty-GEPU, Geopolitical Risk Index-GPR, World Uncertainty Index-WUI, and CBOE Volatility Index-VIX on two important Islamic stock market indices (Dow Jones Islamic Market Index and Bist Participation 100) using wavelet coherence (WTC) and asymmetric Fourier TY analyzes Quarterly data for the period March 2011-June 2023 were used in the study. The results of the analysis show that economic instability indicators impact Islamic equity market indices (both in Turkey and the world). This effect is determined as VIX, GEPU, GPR, and WUI. In addition, the fact that the GPR and WUI indices, which have an impact on conventional markets, have truly little and only a partial impact on Islamic equity markets is an important finding. The results of this study make important contributions to the literature and provide important findings for investors and policy makers.

    Is Islamic Banking Sustainable in Terms of Financial Performance? Empirical Evidence from GCC Countries
    (Research Center Islamic Economics-Ikam, 2024) Kazak, Hasan; Karatas, Ali Rauf; Akcan, Melike Buse; Azazi, Hasan
    The aim of this study is to evaluate the Islamic banking sector with the help of financial performance criteria and to reveal whether the sector is sustainable or not. The sustainability analysis uses the latest unit root tests that take into account Fourier expansions. The study uses unit root tests, which are generally used to analyze the sustainability of public debt, with updated versions that differ from the literature and with the help of financial performance indicators of the banking sector for sustainability analysis. The study uses the data of the Islamic banking sector operating in the member countries of the Gulf Cooperation Council (GCC) for the 4th quarter of 2013 and the 2nd quarter of 2022. The quarterly data of ROA, ROE and Net Profit Margin are considered as financial performance indicators for sustainability analysis. Although the results of the empirical analysis show different results for each of the financial indicators of Islamic banking in the analyzed countries, in general it shows that the Islamic banking sector operating in all GCC countries except the UAE is sustainable in terms of the financial indicators used in at least one category. These results show that the development of Islamic banking is real and promising for the future. Therefore, the development of projects that contribute to the development of the Islamic financial sector and the support of this sector is an important responsibility for the relevant parties. It is expected that these results will provide important signals to the policymakers of the respective countries and contribute to the healthy development of the Islamic banking sector.

    Was the interest burden of the Ottoman public debt sustainable? A cliometric analysis
    (Emerald Group Publishing Ltd, 2024) Hassan, M. Kabir; Kazak, Hasan; Akcan, Melike Buse; Azazi, Hasan
    PurposeThe purpose of this study is to determine whether the Ottoman Empire's net interest payments and foreign debt were sustainable or not in terms of their burden on budget revenues, using the method of historical econometric analysis.Design/methodology/approachIn this study, the period between 1847 and 1882 of the Ottoman Empire is analyzed for sustainability analysis. Within the framework of the study, unit root tests and econometric analysis methods frequently used in the literature were used to analyze the sustainability of public debt. In the econometric analysis, in addition to various unit root tests, current econometric analysis methods, in particular Fourier expansion, were also used.FindingsThe results of econometric analyses showed that the burden of interest payments and foreign debt on the budget of the Ottoman state was unsustainable. This situation clearly shows the reason for the official bankruptcy of the Ottoman Empire, which was declared in 1875.Practical implicationsAlthough this study reveals the bankruptcy process of an important structure such as the Ottoman Empire in the historical process through econometric analyses, it also gives a very important message to today's states. Accordingly, today's state policies and decision-making mechanisms should take these results into account and strive to make the burden of public interest payments sustainable. It is believed that the study will shed light on the public finance policies of today's states by drawing lessons from the collapse process of the Ottoman state.Originality/valueUnlike the historical assessments in the literature on the decline of the Ottoman Empire, this study presents a cliometric approach by applying current econometric analysis techniques to past historical data. The study explains the unsustainability of the Ottoman Empire's interest payments and external debt burden in the period under consideration in a way that, to the best of the authors' knowledge, has not been done before.
