Indian benchmark equity indices snapped a grueling seven-session losing streak on Thursday, August 20, 2026, delivering a sharp recovery. Relief across global bond markets and strong buying in banking, IT, and consumer durables helped headline indices recover strongly off the psychologically crucial 24,000 support level.
The Nifty 50 surged +153.55 points (+0.64%) to settle officially at 24,231.85, recovering off its intraday low of 24,184.55. The BSE Sensex jumped +628.04 points (+0.82%) to close at 77,537.72, while Bank Nifty gained +256.15 points (+0.45%) to finish at 57,495.90.

🚨 SEBI Action on CAS Manipulation (August 13 Expiry Case Analysis)
In a landmark regulatory crackdown, the Securities and Exchange Board of India (SEBI) issued an ex-parte interim order against two major market entities for manipulating the newly introduced Closing Auction Session (CAS) on the August 13 Sensex weekly options expiry.
📌 Case Analysis: How the Manipulation Was Executed
- The Entities: SEBI barred Copthall Mauritius Investment (a JPMorgan Chase & Co. entity) and Mansi Share & Stock Broking from securities markets and impounded ₹3.67 Crore in illegal gains/avoided losses.
- The Modus Operandi: During the 3:15 PM – 3:30 PM auction window on August 13, the two noticees executed opposite, highly aggressive price-impacting strategies. Large buy and sell orders were repeatedly placed and cancelled during the auction to artificially push the Sensex closing VWAP price toward strike levels that favored their large, out-of-the-money options positions.
- The Regulatory Verdict: SEBI Whole-Time Member Kamlesh Varshney noted that these manipulative order placements allowed the entities to wrongfully profit or avoid massive options assignment losses. SEBI reiterated that while CAS is a permanent microstructure reform, real-time order-book telemetry will strictly penalize “spoofing” or artificial price ramping during closing auctions.
🌎 Global Macro Events, Domestic Cues & Crude Oil Update
1. Brent Crude Oil Update
Brent crude futures stabilized near $85.20–$85.80 per barrel, easing off recent highs of $92/bbl following reports of expanding US inventory builds and diplomatic efforts in the Middle East. Lower crude prices provided immediate margin relief to Indian paints, tires, and logistics stocks.
2. US Bond Yields & Global Markets
A cooling of US 10-year Treasury yields from 4.70% down to 4.58% sparked a global risk-on rally. US Fed rate-cut expectations for September remained firmly anchored following neutral US jobless claims data.
3. FII / DII Institutional Flows
Foreign Institutional Investors (FIIs) moderated their cash selling intensity, while Domestic Institutional Investors (DIIs) maintained strong net inflows, ensuring the 24,000 Nifty floor held firm.
