Edwin they are up to their eyebrows in it tho with their exposure. Its too late to get out or hedge anything to limit their losses. They lent money with borrowed money that was borrowed and borrowed again.
Reminds me of one of those property workshops popular in the early 2000's at the height of the property bubble when they said 'buy off-plan homes at cheap rates using other peoples money'.
Fine when your investment increases to a capital worth more than the debt. Not when the investment is junked and the other people want their money back!
