The “eternal return” to a proposal to leave the euro seems to be an irresistable force for some people. A current case in point is Italy, but there are a couple of interesting precedents in the files, like Greece and Ireland.
Italy leaving euro
If I haven’t got the wrong end of the stick, Italy plans is to create a parallel currency to the euro, guaranteed by the Italian government, but which I don’t know who will control. A Bank of Italy? The government would issue these BOT, endorse them with the BI, which would give it the money to be shared out amongst the unpaid creditors. It seems a lot like Helicopter Money.
