Point is, the apparent loan is greater than their entire assets and much greater than all their liabilities.
Unless this 1 publicly traded bank is carrying trillions in secret liabilities, why would they even borrow that much from the Fed.
For example, assume that I lend you $1000 for one day. The following day you pay me back $1000 plus interest, and I lend you $1000 for another day. We keep going for 1000 days, rolling over the debt. TFA would say I have lent you $1M. In reality, I have lent you $1000 for three years or so.

It’s a large numbers market. I guess that’s why TFA liked it. It gave them big scary numbers to use.
Why would you cumulate overnight repos…
Why do you think this?
First, TFA states as much: "repo program that provided nearly $20 TRILLION in cumulative loans to Wall Street".
Second, the Sep 2019 repo crisis is well-known, it lasted multiple weeks, and it was big enough that the Fed wrote a postmortem about it: https://www.federalreserve.gov/econres/notes/feds-notes/what... You can read the details, but the Fed offered very short-term loans in the range of tens of billions, rolled over for an unusually long time.
