Abstract

The recent significant increase in US tariffs has notably influenced India’s trade and export sectors. The tariff measures and associated trade policies introduced by Trump have had a considerable effect on certain Indian sectoral indices, particularly in the energy, IT, pharmaceutical, and traditional labour-intensive industries. These policies also impacted Indian exports and led to fluctuations in the stock market. However, the effects were not consistent across all product categories, and the overall impact on India’s export growth was relatively modest. This is because the effects were confined to specific sectors and could be counterbalanced by broader global trade uncertainties if protectionist measures intensify. The influence of tariff increases under Donald Trump’s ‘New Trade Policy’ on Indian sectoral indices with event windows (-41, +41) for long-term impact is examined with a 180-day estimation period to determine normal returns.
