I'd like to borrow 100 trillion dollars please. I won't actually do anything with it, so you don't need to worry about my credit or ability to repay. In fact, I'll happily keep it in my account at your bank!
(which sounds really hostile, I'm feeling lazy about phrasing it better, I don't mean it to be hostile, of course humor is subjective, blah, blah, blah)
Much like in 2008.
This isn't a problem with an easy answer.
If I'm not mistaken the reason interest rates are so low and the dollar so high is because people are looking for a safe place to put their money where they wont get a hair cut if the bank fails.
Excellent. The interest rate on that account is -3%, but please make sure you maintain a minimum balance of $100 trillion, or we will need to foreclose on your firstborn.
