Sorry, not well verse with US history.
But derivatives product is becoming more sophisticated since 90's.
Yes, those are investment bankers, not ordinary commercial bank.
As far as I knew, no or very little exposure, even got, more like an indirect route, because currently financial world is inter-related.
The 2008 crisis was about credit freeze. Aka banks did not trust each other, result in inter-bank lending cannot function. Everyone fear to lend money out.
In a modern financial system, you need interbank lending to operate to provide daily liquidity for bank to operate.
Bank do not hold on every deposit they had, they lend it out,what if suddenly depositors want to withdraw money in big sum that exceed bank cash level, what they do?
They lend from other bank to give the cash to the depositor.
If one day, no bank want to lend them?
How, tell depositor no money?
Then confidence on the bank collapse instantly.
Once no confidence on the bank, it can cause bank run and result in the bank become insolvency.
Once the news Lehman came out, everyone suspicious on each other, result in freeze in inter-bank lending activities, causing even more stress on banks across.
The crisis is no longer here (2008 global financial crisis), most banks have adequate capital ratio already as compared 2008 time.
The problem currently US has is the fiscal deficit, and debt, no about banks issue anymore.
Thanks for the clarification.
Much appreciated.
