The institutional investors are divided into foreign institutional investors, local institutional investors, active institutional investors, and passive institutional investors. Using a sample of Indonesia listed firms with 2,940 observations from 2012 to 2019, we find that institutional investors is positively correlated with financial leverage. In addition, compared with non-Shariah-compliant firms, Shariah-compliant firms with higher foreign institutional ownership and local institutional ownership have lower financial leverage. Moreover, Shariah-compliant firms with active institutional ownership have higher financial leverage. Finally, we find a significant influence of board characteristics on financial leverage.
