Pengaruh BOPO dan NOM Terhadap Pertumbuhan Aset UUS Bank Asing 2022-2024

Abstract. The Islamic banking industry in Indonesia continues to grow, as reflected by the increasing assets of Sharia Business Units (UUS), including those owned by foreign banks. However, fluctuations in asset growth during the period 2022–2024 have raised concerns regarding operational efficiency and profitability. This study aims to analyze the influence of Operating Expenses to Operating Income (BOPO) and Net Operating Margin (NOM) on the asset growth of foreign bank-owned UUS in Indonesia. A quantitative method with a Vector Error Correction Model (VECM) approach was employed to examine both long-term and short-term relationships between variables. Data were obtained from quarterly financial reports of three selected foreign UUS in Indonesia using purposive sampling. The results show that BOPO has a positive and significant effect on asset growth in the long term, but no significant effect in the short term. Similarly, NOM has a positive and significant long-term effect, but is not significant in the short term. The novelty of this research lies in the application of the VECM method within the context of foreign UUS in Indonesia, offering practical contributions for both management and regulators. A limitation of this study is the relatively small sample size; therefore, future research is recommended to expand data coverage and include macroeconomic variables for a more comprehensive analysis. Abstrak. Industri perbankan syariah di Indonesia terus berkembang, ditandai dengan peningkatan aset Unit Usaha Syariah (UUS) termasuk milik bank asing. Namun, fluktuasi pertumbuhan aset pada 2022–2024 menimbulkan kekhawatiran terkait efisiensi operasional dan profitabilitas. Penelitian ini bertujuan menganalisis pengaruh Beban Operasional terhadap Pendapatan Operasional (BOPO) dan Net Operating Margin (NOM) terhadap pertumbuhan aset UUS bank asing di Indonesia. Metode kuantitatif dengan pendekatan Vector Error Correction Model (VECM) digunakan untuk menguji hubungan jangka panjang dan pendek antar variabel. Data diperoleh dari laporan keuangan triwulanan tiga UUS bank asing di Indonesia yang dipilih melalui purposive sampling. Hasil penelitian menunjukkan BOPO berpengaruh positif signifikan terhadap pertumbuhan aset baik dalam jangka panjang dan tidak berpengaruh signifikan dalam jangka pendek, sementara NOM berpengaruh positif signifikan dalam jangka panjang, namun tidak berpengaruh signifikan dalam jangka pendek. Kebaruan penelitian ini terletak pada penerapan metode VECM dalam konteks UUS bank asing di Indonesia, dengan kontribusi praktis bagi manajemen dan regulator. Keterbatasan penelitian ini adalah jumlah sampel yang terbatas, sehingga disarankan penelitian selanjutnya memperluas cakupan data dan mempertimbangkan variabel makroekonomi.
