To follow up the ask about the Crown’s debts to the Iron Bank. Why do you think the Tywin and Cersei don’t refinance the Crown’s debts by loaning money to the Iron Throne and then using that money to repay the Iron Bank?

Tywin didn’t because of his experience as Aerys II and Robert’s moneyman – he’s spent decades giving away cash, just like his father did, in the hopes of getting his bloodline into the royal line. And now that he has it, he’s intent on making sure he gets paid back, that everyone sees that the Lannisters not only pay their debts, but that everyone pays their debts to the Lannisters.

Cersei didn’t, partially out of a desire to emulate Tywin, and partially because she doesn’t have the best control of Casterly Rock atm and is working with the resources she has to hand, which is the royal government.
