In the two months since the repo market blow up, the Fed has been making repo open market operation purchases at a rate of $1.2 trillion per month.
Below is the monthly rate of Fed open market purchases since 2000. In the era of QE and ample reserves, the Fed has not touched open market operations for more than 10 years before 2019. Prior to that, the highest rate of open market operations we saw in history was roughly $300 billion/month briefly after the September 11 attacks, with long?term averages of around $50 billion/month. To say the current rate of $1.2 trillion/month is unprecedented would be an understatement
