The study aims to measure the intermediary performance of Islamic banks in relation to economic growth in Indonesia in the short and long term. There are four main variables used, namely financing, fund placement in BI (Central Bank of Indonesia), investment in securities, and third-party funds in all Islamic banks from 2007 to 2019. The data were tested using vector error correction models (VECM), Granger Causality, Impulse Response Function (IRF), and Variant Decomposition (VDC) to examine causality relationships, the short- and long-term effects, shocks, and variances in Islamic bank intermediary performance to economic growth. The results show that there is a two-way causality relationship between financing and third-party funds to economic growth. While in the short term, fund placement in BI, investment in securities, and financing have a significant influence on economic growth, but in the long run, only the placement of funds in BI will affect economic growth. Also, only fund placement in BI can shock and significantly contribute to economic growth in the long term. The overall intermediary performance of Islamic banks has not contributed to Indonesia’s economic growth in the long term.
