Synopsis: Indian equity benchmarks, Sensex and Nifty 50, concluded their worst trading week in over a year on Friday, March 6, 2026. Fuelled by a spiraling conflict between the US, Israel, and Iran, the Sensex plummeted nearly 1,100 points in a single day, dragging the broader market lower as global risk sentiment deteriorated.
Sensex Nifty Weekly Fall in Six Years
The final trading session of the week saw a dramatic “risk-off” sentiment as global markets grappled with the reality of an escalating war in the Middle East.
After a brief relief rally on Thursday, the bears returned with a vengeance on Friday, pushing the Nifty 50 below the psychologically crucial 24,500 mark.
How Global War Fears Triggered the Crash
The primary catalyst for this sharp weekly decline was the reported escalation of military strikes involving the US, Israel, and Iran, which rattled global financial markets and pushed commodity prices higher.
The Energy Shock
Crude oil prices surged to 20-month highs, with Brent crude touching $87.66 per barrel on Friday. Brent is now on course to post nearly a 20% weekly gain, marking the sharpest rise since March 2022 following Russia’s invasion of Ukraine.
Investors fear that a broader energy supply shock could significantly increase inflationary pressures in India, the world’s third-largest crude importer, while also widening the country’s current account deficit.
Global Risk-Off Sentiment
The sharp rise in oil prices and geopolitical tensions triggered a broad risk-off sentiment, with investors reducing exposure to equities and moving toward safer assets.
Pressure From Global Investors
Higher crude prices and global uncertainty have also weighed on foreign investor sentiment, contributing to selling pressure in financial stocks and other heavyweights.
Market Performance: Friday’s Closing Snapshot
The sell-off was broad-based, with heavyweights in the banking and financial sectors leading the decline.

Sectoral Winners and Losers
The market weakness was widespread during the week, with 15 out of the 16 major sectoral indices ending in the red, reflecting broad-based selling across the market.
The Laggards
Financial and banking stocks led the decline, as investors worried that higher crude oil prices could keep inflation elevated, potentially delaying interest rate cuts by the Reserve Bank of India (RBI).
The oil and gas sector also faced pressure as oil marketing companies such as BPCL, HPCL, and IOC declined during the week.
The Outperformers
Despite the overall market weakness, defence stocks bucked the trend, gaining nearly 6% during the week.
Companies such as Mazagon Dock, Paras Defence, Solar Industries, and DCX Systems saw strong buying interest amid expectations of increased global defence spending and strong order flows.
