Oh I see, so it’s like a merry-go-round, and everyone wants to have their money returned with more than they borrowed so that not only can they have some left over for themselves, but to also pay back those they themselves borrowed money from in order to lend in the first place. Recursive lending/borrowing up until the central banks, like you said.
Risky stuff. If any single entity along that lending/borrowing chain/network flops, it can send shockwaves to everyone else, all the way back to the central bank.
Thanks for the 2 cents.
