ABSTRACT
Islamic banking played a strategic role in supporting the national financial system through its intermediation function, particularly in mobilizing Third-Party Funds. This study aimed to analyze the effect of money supply, ISSI market capitalization, and conventional banking third-party funds on the growth of Islamic banking TPF in Indonesia during 2020–2025. The study employed a quantitative approach using monthly time-series data from May 2020 to June 2025, obtained from Bank Indonesia, the Financial Services Authority (OJK), and the Indonesia Stock Exchange, and analyzed using multiple linear regression with classical assumption tests. The results showed that money supply and ISSI market capitalization did not have a significant effect on TPF growth, while conventional banking third-party funds had a positive and significant effect. It was concluded that interbank competition within the dual banking system played a more dominant role than macroeconomic and capital market factors. The study implied that Islamic banks should strengthen competitive strategies and improve financial attractiveness to enhance fund mobilization.
Keywords: Conventional Banking, Islamic Banking, ISSI Market Capitalization, Money Supply, Third-Party Funds.
ABSTRAK
Perbankan syariah memiliki peran strategis dalam mendukung sistem keuangan nasional melalui fungsi intermediasi, khususnya dalam menghimpun Dana Pihak Ketiga (DPK). Penelitian ini bertujuan untuk menganalisis pengaruh jumlah uang beredar, kapitalisasi pasar ISSI, dan Dana Pihak Ketiga perbankan konvensional terhadap pertumbuhan DPK perbankan syariah di Indonesia periode 2020–2025. Penelitian ini menggunakan pendekatan kuantitatif dengan data runtun waktu bulanan dari Mei 2020 hingga Juni 2025 yang diperoleh dari Bank Indonesia, Otoritas Jasa Keuangan, dan Bursa Efek Indonesia, serta dianalisis menggunakan regresi linear berganda dengan uji asumsi klasik. Hasil penelitian menunjukkan bahwa jumlah uang beredar dan kapitalisasi pasar ISSI tidak berpengaruh signifikan terhadap pertumbuhan DPK perbankan syariah, sedangkan DPK perbankan konvensional berpengaruh positif dan signifikan. Simpulan penelitian ini menunjukkan bahwa dinamika persaingan antarbank dalam sistem perbankan ganda lebih dominan dibandingkan faktor makroekonomi dan pasar modal. Implikasi penelitian ini adalah perlunya perbankan syariah memperkuat strategi kompetitif dan meningkatkan daya tarik produk untuk mengoptimalkan penghimpunan dana.
