The Fed injected $6.8 billion in liquidity into the market today.

In the past 10 days, approximately 38 billion dollars have been injected, mainly through Treasury bond repurchases.
In other words, this round of repurchase tools has been used continuously and at a high frequency, with a clear purpose - to stabilize short-term financing and prevent interest rates from spiraling out of control.
At the current pace, in two days the 40 billion government bond repurchase quota will be used up.
If you don't want the short-term funding situation to tighten suddenly, there is basically only one way forward: to release new repo quotas.
So now it's not about "how much was given today," but rather whether there will be a continuation of life support.
Once resumed, the market will take it for granted that short-term Liquidity remains in a supportive state. $
