The next crisis will be a surprise until it becomes obvious: 7 financial shocks that are probably in the pipeline now.

 Here's the summary from Law& Liberty

1    What nobody sees coming
2    A purely malicious macro-hack of the financial system.
3    All the central banks get it wrong together
4    A housing collapse again
5    An electricity system failure
6    The next pandemic
7    A major war

Those are the headings.  A quick read at the link fills in the detail.
Of course these are coming and of course there will be some more major wars.
