Why Is Share Market Falling Today? Know Key Factors Behind Sensex, Nifty Decline On May 8

Why Is Share Market Falling Today? Indian equities extended early losses, with benchmark indices trading under pressure amid weakness in financials and select heavyweight sectors on escalating US-Iran conflict and costlier crude oil. As of 9:53 am, the BSE Sensex declined 492 points to trade at 77,351.53 in the opening trade, while the NSE Nifty traded lower by 153 points at 24,172.72.

Financial stocks remained the key laggards, with both private and PSU banks under selling pressure. The Nifty Financial Services fell close to 1%, indicating sustained weakness in the sector and lack of buying support at higher levels.

The broader market, however, showed mixed trends. While midcaps were largely subdued, smallcaps continued to exhibit resilience,

with the Nifty Smallcap 100 and smallcap 250 indices trading marginally higher, suggesting selective participation in the wider market.

Key factors behind market decline

1) Costlier Crude Oil: Brent crude oil rose above $100 a barrel after ‌briefly ⁠slipping below the mark in the previous session, after the US and Iran exchanged fire on Thursday.

2) Persistent FII selling: The foreign institutional investors (FIIs) sold equities worth Rs 340.89 crore on Thursday.

3) US-Iran Conflict: Indian equity markets remain under pressure as escalating geopolitical tensions in West Asia continue to weigh heavily on investor sentiment despite periodic relief rallies. The latest exchange of fire between the US and Iran near the Strait of Hormuz has further heightened uncertainty, even as Donald Trump called on Tehran to accept the US proposal and reiterated that Washington does “not seek escalation”. The contrast between military confrontation and diplomatic messaging has kept investors on edge, curbing risk appetite and reinforcing a defensive undertone across global financial markets.

4) Rupee Falls Below 94.5: The Indian rupee has again slipped below the 94 mark. The local currency traded at 94.55 against the US dollar in the early trade, compared with the previous close of Rs 94.22.

5) Oil, Financials, Metal, Realty Under Pressure: Sectorally, weakness was visible in oil & gas, metals, realty, and banking stocks. The oil & gas index dropped over 1%, reflecting concerns around rising crude prices, while metals also saw mild selling pressure. On the other hand, IT stocks provided some support, with the index gaining over 0.6%, aided by selective buying in export-oriented names. Healthcare and mid-smallcap healthcare indices also traded in the green, indicating defensive rotation.

Nifty Technical View

Anand James, chief market strategist at Geojit Investments Ltd, said, “Despite the push beyond last week’s peak, the rejection trades that surfaced on approach of the upper bollinger band resulted in an inverted hammer, neutralising prevailing uptrend. We will hence start today on a weak note, but with hopes of a recovery swing on approach to 24180/140. Inability to do so will expose 23,750-23,540.”
