Quote from Martinghoul:
Well, firstly, a devaluation and a default are, in many ways, similar (certainly to a local ccy bond investor). Secondly, again, you *think* it's not the ccy devaluation that saved Iceland. The fact of the matter is that trade-weighted ISK is now almost 50% less than it used to be before 2008. How do you know that it's the default and not the ccy that really allowed the Icelandic economy to get back on its feet? Again, if Iceland doesn't float your boat, there's a lot of other examples.
As to what class of people it benefits, it's easy enough to look at what sector of the economy performs best after a devaluation. All else being equal, banks normally get killed, 'cause they inevitably suffer runs, etc. The govt suffers, 'cause normally they're locked out of the bond mkt for a while (although with Iceland, it was quite a short hiatus). Property mkt probably benefits, 'cause property becomes cheaper to external investors. Manufacturing is what really kicks off, like, for example, it did in 2009-10 in the UK after the pound depreciated 30%.
