I occasionally entertain myself thinking about this set of puzzles:
(1) It is good for financial regulators and probably, let’s say, the world, if creditors are slow to pull money out of banks that run into trouble. In particular you don’t want everyone to want to move first and get their money out well before there’s a problem, because them getting their money out creates, or let’s say at least exacerbates, the problem.
(2) Banks also want that, since going bankrupt for no reason seems sort of harsh.
(3) But creditors want their money back – and being first out the door is a good way to ensure that that happens.
And since, when things go pear-shaped, there’s always some risk either that the rules won’t let the creditors move as fast as they want, or that the rules will change, it’s good to get your money out before there’s a problem. The best way to do that is just to keep your money to begin with, or only to give it to people who won’t get into trouble, but failing that, you want to get your money back when there’s a hint of trouble but things are still mostly fine. For some reason credit ratings used to indicate that state, since they worked so well last time, so a downgrade from nice investment grade to less-nice-but-still-investment-grade is a good time to check in with your money and see if it might miss you and want to spend a bit more time with you.
On the other hand, if you are a bank and you agree to terminate or collateralize lots of contracts upon a downgrade, you tend to have to come up with lots of cash at exactly the wrong time. So it is probably smart practice to mostly not agree to that sort of thing. But life being what it is you can’t win them all, so you agree to have some trigger-on-downgrade collateralization in some of your contracts, and you just push for those triggers to be as few and as far away from your current ratings as possible.
Anyway, let’s check in with some counterparties’ money: Read more »
