Sensex has dropped below 800 points in intraday trade. It declined 807.67 points, or 1.07%, to hit an intraday low of 74,503.39. NSE Nifty also fell 247.55 points or 1.08% to 22,548.35. One of the reasons behind the crash is said to be the uncertainty over Donald Trump's tariffs as his administration will soon impose "reciprocal tariffs" in India.
