Why stock market is falling today: Sensex tumbles over 800 pts, Nifty sinks below 24,600; 4 key reasons behind the decline

Indian markets fell sharply on May 22, with the Sensex dropping over 800 points and the Nifty below 24,600. Key reasons include a spike in U.S. Treasury yields, Moodys downgrade of the U.S. credit rating, weak U.S. bond demand, and a technical correction after a recent rally. These factors combined to trigger global risk aversion and selling pressure in India.
