Infrastructure is the backbone of modem economies; an adequate and efficient public infrastructure is essential for nations to achieve their economic growth objectives. Although the need and role of infrastructure are well recognized, little attention has been paid to the risks and pitfalls of the current infrastructure financing structures. The enormous infrastructure deficit and the increasing instances of debt restructurings, infrastructure project failures and expensive government bailouts, present enough reason for a deeper thought and action towards making infrastructure financing more robust. Through the thesis, the researcher sheds light on the problems related to such forms of financings and presents the case for an alternative model to finance infrastructure developments. The objective is to structure instruments based on Islamic risk-sharing principles and evaluate their efficacy to finance infrastructure projects. To test the viability of such instruments, we use the case study approach, whereby the cases of the Euro Tunnel and the Taiwan High Speed Rail have been simulated and backtested, to demonstrate how fortunes of these projects would have been different considering the use of the proposed instruments instead of conventional interest-bearing debt. The findings of the cash flow remodel are positive for both the cases and the introduction of the proposed instrument within the two project capital structures adds robustness to the projects. Moreover, the risk adjusted returns for investors tends to be higher in comparison to the conventional infrastructure financing structures. The findings provide a strong argument towards the use of lesser leverage for infrastructure financing and the use of risk-sharing instruments by governments to develop infrastructure. The proposed instrument while providing stability to infrastructure projects and economic benefits to its investors, is Shariah compliant or in line with the tenets of Islamic law and thus can be used by Shariah conscious investors to generate superior returns and by policy makers to further build the Islamic capital markets.
