Fenomena bonus demografi yang sedang terjadi di Indonesia membuat pemerintah diharapkan mampu untuk memanfaatkan peluang tersebut dengan mendorong pembangunan ekonomi, yang salah satunya dapat dilakukan dengan menyusun kebijakan ekonomi yang mendukung peningkatan akses tabungan dan investasi nasional. Salah satu industri yang perlu menjadi perhatian pemerintah dalam hal tersebut adalah industri perbankan syariah, yang saat ini antara pemerintah dengan industri sedang bersama-sama mengembangkan produk Sharia Restricted Intermediary Account (SRIA). Dalam hal pengembangannya, pemerintah dan industri perlu mengetahui faktor apa saja yang dianggap berpengaruh terhadap minat masyarakat terhadap penggunaan produk SRIA itu sendiri. Berdasarkan theory of planned behaviour, penelitian ini bertujuan untuk mengetahui faktor psikologis apa saja yang dianggap berpengaruh terhadap attitude, subjective norms, perceived behavioral control, serta intention (minat) seseorang dalam hal penggunaan produk SRIA. Metode non-probability sampling digunakan dalam penelitian ini dengan sebanyak 280 responden dan dianalisis menggunakan pemodelan Partial Least Squares-Structural Equation Modeling (PLS-SEM). Hasil penelitian menunjukkan bahwa faktor compatibility dan relative advantage dianggap berpengaruh secara positif terhadap attitude seseorang terhadap produk SRIA, sedangkan uncertainty menunjukkan hubungan yang negatif. Lalu faktor spirituality dan normative belief dianggap berpengaruh secara positif terhadap subjective norms, kemudian faktor selfefficacy dan facilitation condition dianggap berpengaruh secara positif terhadap perceived behavioral control. Kemudian, attitude, subjective norms, dan perceieved behavioral control seseorang menjadi faktor yang dianggap berpengaruh secara positif terhadap intention atau minat seseorang dalam hal penggunaan produk SRIA.
