BSE SENSEX Index Crashes Over 1,100 Points in Intraday Trade Today (September 24, 2026): Know the Key Reasons

The BSE SENSEX Index opened the September 24, 2026, session lowered at 74,272.40 and struggled to find upward traction, registering an intraday high of 74,362.29. The index later plummeted to an intraday low of 73,582.25 as aggressive liquidations unfolded.   

The index is locked in the red amid massive selling pressure triggered by weak global cues, rising crude prices, surging bond yields, and proposed domestic insurance regulatory reforms.   

The 5 Key Reasons Driving This Sharp Market Decline 

• Surging US Treasury Yields: A global bond rout pushed the US 10-year Treasury yield to a 19-year high near 5.11%. This spike stoked fears that global interest rates will remain higher for longer, diminishing the appeal of riskier emerging market assets.  
• Spike in Crude Oil Prices: Fueled by renewed diplomatic uncertainty surrounding the US-Iran conflict, Brent crude prices jumped past $102–$106 per barrel. Elevated oil prices aggravate inflation worries, expand India's import bill, and hit corporate profitability.  
• Proposed IRDAI Insurance Reforms: Shares of major banking and insurance companies crashed following a draft proposal by the Insurance Regulatory and Development Authority of India (IRDAI). The proposed commission caps and distribution payout restrictions severely dented expected profit margins for institutions like PB Fintech (which plunged up to 30%), Bajaj Finance, and Axis Bank.  
• Monthly Derivative Expiry Volatility: Today marks the Sensex monthly derivatives expiry, which triggered heightened intraday selling pressure and technical stop-loss triggers once major support levels were breached.  
• Overnight losses on Wall Street and deep sell-offs across major Asian bourses triggered a global "risk-off" sentiment, prompting foreign institutional investors (FIIs) to pull back capital.
