The week was very bad for the stock market and the new tariff attack by the US caused a stir in the Sensex-Nifty. Yes, the US President first increased India from 25% to the reciperochl tariff 50%, then suddenly increased the fees of H1B Visa and now announced a 100% tariff on the pharma sector from October 1, due to its impact, there was a stir in the stock markets around the world and the Indian stock market also crashed. Due to this, about 3 lakh crore rupees of Sensex’s top-10 companies were destroyed in five business days of the last week. Companies like TCS, Reliance and Infosys were the biggest losses.
Trump’s announcement here, stock market crash there

A 30 -share Sensex of BSE’s 30 -share Sensex in a whole week was broken by 2,199.77 points i.e. 2.66%. Due to this, all of the Sensex’s top-10 valuable companies declined strongly and the investors’ hard-earned money was submerged.

America’s new tariff bomb
It is worth noting that the impact of Trump’s increase in H1B visa fees from the stock market was not reduced, that Donald Trump made a big announcement on his trousing social account and said that 100% tax on pharmaceutical drugs, 50% tariff on kitchen cabinet and bathroom vanities, 30% on upholstered furniture and 25% on heavy tariffs will be put on heavy. He said in his post that these tariffs will be applicable from October 1, 2025. Since then, the market has slipped badly.
