The rapid development of Islamic banking in Indonesia faces significant challenges in maintaining liquidity and profitability amidst dynamic capital market conditions. The urgency of this study arises from the need to examine whether traditional financial ratios, such as the Financing to Deposit Ratio (FDR) and Return on Equity (ROE), play a decisive role in influencing investment decisions, which are proxied by the Price to Earning Ratio (PER). The main objective of this research is to empirically test the effect of liquidity and profitability, both partially and simultaneously, on investment decisions in Islamic commercial banks listed on the Indonesia Stock Exchange during the 2021–2025 period. This study adopts an associative design with a quantitative approach, utilizing secondary data from financial reports obtained from the IDX, and analyzed using multiple linear regression on 68 observation samples. The findings reveal that neither liquidity nor profitability significantly influence investment decisions, either partially or simultaneously. These results suggest that investors in the Islamic banking sector tend to prioritize non-financial factors such as sharia compliance, governance, macroeconomic conditions, and ESG trends, rather than conventional financial indicators. In conclusion, this research extends the understanding of the limitations of Signaling Theory in the sharia context and recommends the development of a more holistic investment evaluation model. Future studies are encouraged to incorporate non-financial variables for a more comprehensive analysis.

Economic globalization is a process that significantly impacts the structure and values within Islamic political economy. Market integration, trade liberalization, and cross-border capital flows have created an increasingly competitive and capitalistic global economic order. On one hand, globalization provides opportunities for developing countries, including Indonesia, to access new technologies, expand export markets, and increase foreign investment. However, on the other hand, globalization also poses serious challenges for Islamic political economy, particularly due to the dominance of capitalist principles that contradict the fundamental values of Islamic economics, such as justice ('adl), balance (tawazun), and the prohibition of riba and gharar. Additionally, internal challenges such as low community literacy, a lack of innovation in Sharia-compliant financial products, and insufficient policy support further hinder the development of the Islamic economy. This research employs a descriptive qualitative method based on literature studies to analyze the impact of globalization on Islamic political economy. The findings indicate that adaptive strategies, innovation enhancement, regulatory strengthening, and the improvement of literacy and research are necessary for Islamic political economy to play a strategic role in addressing the challenges of globalization. Thus, it is hoped that Islamic political economy can contribute to the realization of a more just and sustainable global economic order.

Competition law is an important instrument in maintaining healthy and fair market dynamics, especially in the era of globalization marked by increasingly competitive economic growth. This article discusses how business competition takes place at the regional level, with particular attention to the obstacles faced by small entrepreneurs in facing the dominance of established companies. The competition that emerges is not only limited to price issues, but also involves difficulties in accessing capital, distribution networks, technology, and unfavorable regulations. Existing companies generally have strong structural strengths and networks, which create major barriers for new entrants. In addition, there are signs of unfair competitive practices that can threaten the survival of small businesses. However, advances in technology and digitalization are opening up new avenues for small entrepreneurs to enter the market and establish direct relationships with customers. This article aims to identify various forms of business competition at the local level, analyze the opportunities and challenges that exist, and develop strategies that encourage the creation of a healthy and inclusive competitive environment for the sustainability of local economic growth.

Indonesia's Sharia capital market has experienced significant growth in the past decade, along with rising public awareness of Islamic economic principles and the adoption of digital technologies. This study aims to analyze the role of digital transformation in supporting the development of the Sharia capital market and to identify structural challenges, particularly in regulatory, financial literacy, and cybersecurity aspects. The methodology used is descriptive qualitative with a literature study approach, drawing on secondary data from reputable journals and official publications from OJK and the Indonesia Stock Exchange. The results indicate that while technological transformation has opened significant opportunities such as increased financial inclusion and youth investor engagement, the Sharia capital market still faces serious challenges related to unadaptive regulations, cyber threats and low investor literacy. This study recommends synergy between regulators, industry players and educational institutions to strengthen a sustainable Sharia capital market ecosystem.
