Abstract: Purpose - This conceptual paper aims to explore portfolio replication to resolve post-COVID pandemic private and public debt. This paper stresses the need to be less dependent on a debt-based system and the emergence Islamic equity market. Design/methodology/approach - This study analyses different types of risks involved in Islamic and conventional portfolios by using risk measures such as relative beta and comparatively examining the systematic and downside risk exposure of Islamic and conventional portfolios. Data was collected monthly from 2016 to 2022. Findings - The findings indicate that the replications of a conventional portfolio into an Islamic portfolio are compatible with the regulatory standard, sharia boundaries and professional practices developed from investment theory. The result shows that Islamic portfolios have lower risk exposure compared with their conventional counterparts in most of the sample years, therefore, become further attractive for debt–equity portfolio swaps and Sharia-compliant investors preferring low-risk preferences. The result confirmed that the Islamic portfolios have a higher return and less risk than conventional portfolios. Research limitations/implications - The implications of this research are to provide a road map to the regulators, policymakers, governments and the financial industry on how to rearrange some of the public and private debt. A likely remedy is incorporating Islamic financial instrument principles through the equitisation of public and private debt. Practical implications - This research contributes to investors (particularly those who want to avoid riba [usury] based investment) to make more diversified portfolios by considering Islamic portfolios to reduce risk exposure. Originality/value - To the best of the authors’ knowledge, this is the first paper to create bivariate debt–equity portfolios swaps composed of Islamic and conventional assets.
