Sensex, Nifty extend 4-session losing streak as US-Iran tensions lift oil
Synopsis
Indian markets logged a fourth straight session of losses on 23 July as US-Iran tensions drove crude oil higher, hammering banking, realty, and energy stocks. With Nifty slipping below 24,000 and that level now acting as resistance, the technical picture has turned decidedly cautious — and the next move in global crude could determine whether the slide deepens.
Key Takeaways
Sensex fell 364 points to close at 76,391.39 on 23 July — its fourth consecutive losing session.
Nifty50 settled at 23,869.60 , down 127 points or 0.53% .
Nifty Realty was the worst-hit sector, dropping 1.81% ; Nifty PSU Bank fell 1% and Nifty Bank slid 0.94% .
Rising crude oil prices, triggered by fresh US-Iran geopolitical tensions, were the primary drag on sentiment.
Nifty Auto (+ 0.70% ) and Nifty Media were the only major sectoral gainers.
Analysts flag 24,000 as immediate resistance and 23,800 as the key support level to watch.
Indian equity benchmark indices extended their losing streak to a fourth consecutive session on Thursday, 23 July, as surging crude oil prices — driven by fresh escalation in US-Iran geopolitical tensions — kept investor sentiment firmly in the red. The BSE Sensex declined 364 points, or 0.47%, to close at 76,391.39, while the Nifty50 shed 127 points, or 0.53%, to settle at 23,869.60.
Key Levels to Watch
Market analysts noted that the 24,000 mark, which previously served as a key support, has now flipped into immediate resistance, reinforced by the highest Call Open Interest (OI) concentration at the 24,000 strike. A stronger resistance band is reportedly placed near 24,200.
On the downside, analysts said the 23,800 zone remains the immediate support, underpinned by a secondary Put OI cluster. A decisive break below this level, according to technical experts, could accelerate selling pressure toward 23,700, and subsequently toward 23,500 — where the highest Put OI is currently concentrated.
Sectoral Damage
The sell-off was broad-based. The Nifty Realty index was the session's biggest sectoral loser, falling 1.81%. The Nifty PSU Bank index slipped 1% and the Nifty Bank index declined 0.94%. The Nifty Chemical and Nifty Oil and Gas indices also ended in the red, weighed down by concerns over rising energy costs.
In contrast, the Nifty Auto index bucked the trend, gaining 0.70%, while the Nifty Media index also closed in positive territory.
Top Movers
Among Sensex constituents, Bajaj Finance, IndiGo, Axis Bank, and Reliance Industries featured among the major losers. Within the Nifty pack, Nestle India and Shriram Finance were the session's top laggards.
On the gaining side, Mahindra & Mahindra, Tata Consultancy Services (TCS), Eternal, HCL Technologies, and Bajaj Finserv emerged as the top performers of the day.
What Is Driving the Caution
Experts said market sentiment remained cautious as investors weighed the implications of escalating Middle East tensions. Higher crude oil prices raise concerns over domestic inflation and their downstream impact on corporate earnings — a particularly sensitive pressure point for an import-dependent economy like India. This is the fourth straight session of losses, underscoring the depth of the current risk-off mood. Markets will closely track further developments in the US-Iran standoff and any corresponding moves in global crude benchmarks in the sessions ahead.
Point of View
And the market is pricing that in. What is notable here is that even sectors with no direct oil linkage, such as real estate and banking, are selling off, suggesting the damage is as much about sentiment and rate-expectations as it is about energy costs. Until Nifty reclaims 24,000 with conviction, the path of least resistance remains downward, and a break below 23,500 could trigger a broader de-rating of risk assets.

Frequently Asked Questions
Why did Sensex and Nifty fall on 23 July 2025?
The Sensex fell 364 points and Nifty dropped 127 points on 23 July primarily due to rising crude oil prices triggered by fresh escalation in US-Iran tensions. Higher oil prices raised concerns over inflation and corporate earnings, dampening investor sentiment across banking, realty, and energy sectors.
What is the key technical level for Nifty after this fall?
Analysts identify 24,000 as the immediate resistance level for Nifty, having previously been a key support. On the downside, 23,800 is the immediate support, and a break below it could push the index toward 23,700 and then 23,500, where significant Put OI is concentrated.
Which sectors were hit hardest in Thursday's session?
Nifty Realty was the biggest sectoral loser, falling 1.81%, followed by Nifty PSU Bank (down 1%) and Nifty Bank (down 0.94%). Nifty Chemical and Nifty Oil and Gas also ended lower amid energy cost concerns.
Were there any gainers in the market on 23 July?
Yes, Nifty Auto gained 0.70% and Nifty Media also closed in positive territory. Among individual stocks, Mahindra & Mahindra, TCS, Eternal, HCL Technologies, and Bajaj Finserv were the top performers.
How does the US-Iran tension affect Indian stock markets?
Escalating US-Iran tensions typically push global crude oil prices higher. For India, which imports a significant share of its oil needs, rising crude raises inflation risks, compresses corporate margins, and increases the current account deficit — all of which weigh on equity valuations and investor sentiment.
