Sorry. I don't have a lot of time for Bloomberg journalism. Most of the information was obvious on Wednesday and out of date by Friday.
Yes, there was a sharp increase in the turnover in US Treasuries last week and some price volatility. And then the market calmed down.
Why you think this sort of volatility would cause problems for the Fed? They are a central bank. Their depositors are US government departments and US commercial banks so there isn't going to be a "run on the bank".
The Fed would have been monitoring events for potential threats to financial system stability (as is their mandate), but after the GFC and its various after shock, last week was a side show.
