In terms of duration: I would say they are one regular recession away from this. For the last 5 years I've been saying "next 2 years". Today I'd say 1 year. (I have no actual money involved so this prediction is worthless. But you asked for it...)
It was the same with Greece: people had months or even years to yank their money from the bank. The trainwreck was telegraphed way in advance. It's just that nobody did it because they couldn't imagine it.
It's a similar psychological process that is keeping Japanese markets disciplined for such a long time.
By contrast, in a country like Argentina people have living memories of monetary disasters and they trigger much quicker.
