(because the media is full of apocalyptic predictions at the moment)
I think that the Irish government’s decision to guarantee all deposits held in Irish-regulated banks is essentially a massive bluff-calling exercise. They’re potentially exposed to losses of EUR 400 billion (although this theoretical maximum exposure would only be realised if the Irish banks’ assets turned out to have a combined value of zero euro – even with plummeting house prices, that won’t ever be the case!).
In the event of a total banking collapse, with all assets being worth zilch, the government would obviously never be able to pay out EUR 400 billion (amounting to EUR ~100,000 for every man, woman and child in the state!).
I can see why they’ve said it, and it’s (as far as I can see) quite sensible but…what they really mean is:
Well…we’ll try to guarantee your savings (or any loans that you might have made to the banks), but…y’know, if more than one bank goes under, we’re all fecked so don’t expect any more than a copper coin and the address of a soup kitchen (run by a chinese international aid agency).
