The morning brief anticipated a soft to flat start with GIFT Nifty hovering near 24,900, but the session unfolded with sharper downside than projected. The impact of proposed US pharmaceutical tariffs materialized more severely than expected, with the pharma sector declining 2.2%, exceeding our cautious stance.
Key validation
Subscriber feedback synthesis highlighted concerns around the cascading impact of US pharma tariffs and their implications for India’s $10.5B pharmaceutical exports to the US.
From October 1, 2025, the United States plans to impose a 100% tariff on branded or patented pharmaceutical imports, with exemptions for companies that have already initiated US manufacturing. Generics are not targeted. For Indian pharma, direct exposure remains concentrated in specialty and branded portfolios, while API-focused firms face limited direct risk. Indirect effects through sourcing and partner behavior remain key watch items.
Validated closes (26-Sep-2025)
All major sectoral indices closed lower, reflecting broad-based selling pressure.
Weakness was driven by tariff uncertainty, sustained FII outflows, and continued rupee pressure.
Despite the seventh consecutive decline, Nifty is only ~5.5% below its September 2024 peak, indicating index-level resilience compared to individual stocks, where 485 mid- and small-cap names are down over 20%.
A notable micro-pattern emerged: selling intensity clustered in high US-exposure cohorts (large-cap IT and export-oriented pharma), while select domestic cyclicals held relatively steadier on a beta-adjusted basis. External-shock beta dominated domestic-demand beta during the session.
INR/USD
The rupee continues to trade near record-weak zones, pressured by sustained FII outflows.
