This will be very interersting to watch.
Be aware, though it looks similiar, the economy is different today.
2008 was 2008, there have been a lot of changes behind the stage, about banks and their financial structure.
2016 is NOT 2008! You will see the difference end of this year.
You are right! The world has had half the debts in 2008. Seriously, there were implemented new financial instruments and rules like Basel III and others. But they all will not help when the crash happens.

All banks around the world are struggling with defaulted toxic loans, especially loans given to companies exploring and mining natural resources.
You just only have to wait and what is going to happen in the future. But holding is better than spend now on this time.
