I wish I could disagree with Nouriel Roubini when he says this:
. . . if you cannot devalue, or grow, or deflate to a real depreciation, the only option left will end up being to give up on the euro and to go back to the lira and other national currencies. Of course that will trigger a forced conversion of euro debts into new national currency debts.
The eurozone can survive with the debt restructuring and exit of a small country such as Greece or Portugal. But if Italy and/or Spain were to restructure and exit this would effectively be a break-up of the currency union. Unfortunately this slow-motion train wreck is now increasingly likely.Only if the ECB became an unlimited lender of last resort and cut policy rates to zero, combined with a fall in the value of the euro to parity with the dollar, plus a fiscal stimulus in Germany and the eurozone core while the periphery implements austerity, could we perhaps stop the upcoming disaster.
