I think the financial system has stalled, not crashed. There's quite a bit of wait-and-see happening, and credit is very much harder to come by than it was a year ago - which is hardly a bad thing considering how money was being loaned to anyone who could pass a medical test for the most rudimentary evidence of brain activity.

But the system as a whole is still functioning. Money - fictional as it is - is still being counted.

We'll know the system has crashed when trade goes back to barter and/or gold.
