Abstract

This study aims to examine the short-run and long-run relationships between world oil prices, the Rupiah exchange rate, Bank Indonesia’s policy interest rate (BI Rate), imports, and inflation in Indonesia. The analysis employs a Vector Error Correction Model (VECM) using monthly data from 2010 to 2024, supported by unit root tests (ADF and PP), Johansen cointegration test, and ARDL bounds test for robustness. The results show that most variables are non-stationary at level but become stationary at first difference I(1), and the Johansen cointegration test identifies two cointegrating vectors, indicating long-run equilibrium relationships among variables. In the short run, inflation is mainly influenced by its own past inertia (over 90% in FEVD), and none of the external transmission channels are significant. In the long run, oil prices and exchange rates correlate negatively with inflation (coefficients of -0.223 and -16.963), while imports have a strong positive influence (coefficient of 26.425), and the BI Rate is statistically insignificant.

Abstrak
Penelitian ini bertujuan untuk mengkaji hubungan jangka pendek dan jangka panjang antara harga minyak dunia, nilai tukar Rupiah, suku bunga kebijakan Bank Indonesia (BI Rate), impor, dan inflasi di Indonesia. Analisis ini menggunakan Model Koreksi Kesalahan Vektor (VECM) dengan data bulanan dari tahun 2010 hingga 2024, yang didukung oleh uji akar unit (ADF dan PP), uji kointegrasi Johansen, serta uji batas ARDL untuk menguji ketahanan model. Hasilnya menunjukkan bahwa sebagian besar variabel bersifat non-stasioner pada level tetapi menjadi stasioner pada selisih pertama I(1), dan uji kointegrasi Johansen mengidentifikasi dua vektor kointegrasi, yang mengindikasikan adanya hubungan keseimbangan jangka panjang di antara variabel-variabel tersebut. Dalam jangka pendek, inflasi terutama dipengaruhi oleh inersia masa lalunya sendiri (lebih dari 90% dalam FEVD), dan tidak ada saluran transmisi eksternal yang signifikan. Dalam jangka panjang, harga minyak dan nilai tukar berkorelasi negatif dengan inflasi (koefisien sebesar -0,223 dan -16,963), sementara impor memiliki pengaruh positif yang kuat (koefisien sebesar 26,425), dan BI Rate secara statistik tidak signifikan.
