This study aims to examine the spillover and contagion effects of global financial markets on the Indonesian Sharia Stock Index (ISSI) post-COVID-19. The study uses the Vector Error Correction Model method to explore the short-term and long-term relationships between ISSI and global financial markets. The data used in this study are time series data, namely the ISSI and several other countries that have a significant influence on the global economy, which were observed from May to July 2022. The results of the study show that the USD has a positive influence on ISSI in the short and long term. At the same time, the JPY and HKD have a negative influence on ISSI. The GBP and SGD do not have a significant influence on ISSI developments. The economic, business and financial sectors began to adjust after the COVID-19 pandemic ended, including the Indonesian Sharia Stock Index. Contagion occurs from one country’s financial system to another, which is influenced by aspects of volatility, exchange rates, the global crisis, the stock market, and stock indices. It is considered that this study can help the government to adjust better conditions of Islamic stocks in Indonesia.

The volatility of rising oil prices has certainly made the market more out of control. Market participants are very sensitive to various information and to global issues such as Russia’s invasion of Ukraine. This study aims to review the reaction of the Indonesian Islamic stock market in the energy sector before and after Russia’s invasion of Ukraine. The variables used are stock returns, abnormal returns, and trading volume activity. The sample of this study is represented by Indonesian sharia stocks in the energy sector using a purposive sampling method. The research period was from February 4, 2022 to March 18, 2022. The research method used was the Event Study Method (ESM) and paired sample different tests with the Microsoft Excel program and SPSS version 26. The results of the study show that there is a significant difference in the average stock returns in the periods of 3, 7, and 14 days before and after Russia’s invasion of Ukraine. There are also differences in abnormal returns for the 3-day and 14-day observation periods, while for the 7-day observation period, there are no significant differences in abnormal returns. Besides, there is an average difference in volume activity during the periods of 3 days, 7 days, and 14 days before and after the Russian invasion of Ukraine. Indirectly, this information about Russia’s invasion of Ukraine affected the performance of the capital market. This also shows that the semi-strong form of the efficient market hypothesis is proven in this study.
