“On March 18, 2015 between 4:02 and 4:09 PM Eastern Daylight Time, the U.S. Dollar flash crashed, losing over 3% of its value in just under 4 minutes, then gaining most of it back over the next 3 minutes. This event occurred 4 minutes after the regular session of stock market trading closed on the NYSE and Nasdaq at 4 PM (16:00). Two hours earlier, at 2 PM, was the widely anticipated and watched Federal Open Market Committee (FOMC) event. A quarter of a second after the initial 2 PM announcement, the U.S. stock market exploded higher. At the same time, the U.S. Dollar moved sharply lower, setting up conditions for the flash crash 2 hours later.” taken from
