Sukūk is one of the products of Islamic financial institutions IFIS), so the rating of such instruments should be considered. This study aims to provide empirical evidence of the influence of Good Corporate Governance on Ṣukūk rating, with financial performance as a mediating variable. Multiple regression, ordinal logistic regression and Sobel test were used to test the Assumptions on 222 Ṣukūk, which were listed on the Indonesia Stock Exchange as of December 31st, 2020. The results show that the supervisory board's size, independence, experience, and the audit committee's size and experience directly affect the Ṣukūk rating. Financial performance has also been shown to have a direct influence on Ṣukūk rating, which in turn can mediate the effect of the three elements of the Good Corporate Governance supervisory function on Ṣukūk rating, namely: the size of supervisory boards, the independence and the number of Sharīʿah supervisory boards.

This study confirms that the existence of a Sharīʿah supervisory board can support the achievement of financial performance and Ṣukūk rating in IFIs.
