I’m way out of my league on the intricacies of bank repo and counterparty risk, but this does seem to tie directly to the ongoing concern about Private credit and big bank exposure to same.
As noted by some:
"The distinction that matters is collateral quality and loan duration, not private credit exposure alone, since long dated AI infrastructure debt can look fine until refinancing turns hostile"
Meaning, it was fine until it wasn't
Probably nothing...
