The current focus emphasizes the difficult choices faced by Indian management of the impossible trinity to manage import-led growth. The management highlights two mechanisms by which FDI (foreign direct investment) flows are easily substituted for short-run FII (foreign institutional investment) flows. First, GDP and its growth in an open economy framework and the associated international trade participation can clarify this substitution prospect. Specifically, this study develops reasoning whereby imports under the trilemma management can give some decisive advantage to FII at the cost of FDI to manage Indian import-led growth. Second, it underlines how the related policies, especially the sterilization interventions, constrain the interactions of higher domestic investments (domestic savings), spillover impacts of imports of intermediate and capital goods, and specialized FDI. If so, the Indian economy’s import-led growth can indicate FII and FDI tradeoffs. The study uses the ARDL regression method. The results show that the Indian policy-led macro environment can limit the scope of specialized FDI that aims to induce advanced domestic investment, exports, and FDI interactions. India’s focus on import-led growth thereby underpins how FII substitutes FDI.
