With EU–India clinching a post-Brexit trade negotiation, the present paper proposes to examine whether the free trade agreement between the two regions would increase production efficiency and thereby social welfare. Using the partial equilibrium model, the study reveals that the EU–India FTA yields less positive trade and welfare gains in India after Brexit specifically, for consumer, industrial, and capital goods, whereas it would still be in India’s interest towards the specific benign impact of an FTA in raw materials, intermediate goods, and agricultural goods. From the policy perspective, India is not well-served by its pursuit of protectionist agenda and instead should push for trade liberalisation as a better path for the global trading system.
