PurposeThe purpose of this study is to examine the relationship between intellectual capital, sharia governance and Islamic bank performance based on the maqasid sharia index, as well as the moderating effect of sharia governance on the relationship between intellectual capital and maqasid sharia index.Design/methodology/approachDynamic panel regression is used with the two-step generalised method of moments with data from the Bankscope database for 2014–2018.FindingsThe results show that higher intellectual capital efficiency improves Islamic bank performance based on maqasid sharia. Larger board sizes are also found to improve Islamic bank performance. By contrast, higher sharia supervisory board quality and larger independent boards can reduce Islamic bank performance. In the moderating relationship, sharia governance is proven to moderate the relationship between intellectual capital and Islamic bank performance.Research limitations/implicationsThis study used a sample that is restricted to Islamic bank and only used value-added intellectual coefficient to measure intellectual capital. Thirdly, the quality of the sharia supervisory board only involves the presence, size, expertise and doctoral qualification of the sharia supervisory board.Originality/valueThis research: analyses the relationship between intellectual capital, sharia governance and Islamic bank performance in one research framework; uses maqasid sharia index-based Islamic bank performance benchmarks; and examines the moderating effect of sharia governance on the relationship between intellectual capital and maqasid sharia index.
