One update upon a second look, the only other time I can see similar action was July 1998. Back then was one of (if not the first) off cycle FED interventions because of a ‘currency crisis’.
The 10-2 spread dipped into negative territory momentarily, and then jumped back up. However the spread recovery is no where near as fierce as post coronavirus, or 2008, or 2001.
After July 1998 the Nasdaq increases 350% to March 2000. Sound familiar?
