Perhaps Stalker was being a tad flippant last month when suggesting that a UK exit from the EU may not matter too much.
A leading London think-tank, Open Europe, estimates that Ireland would lose £2 billion per year in trade with the UK if it did follow through on exiting the EU. That’s not insubstantial. As for the Greek situation - if it left the euro, there is every possibility of contagion according to top Swiss bank UBS. UBS reckon other unmanned eurozone countries could very quickly end up outside the euro due to bank runs.
Stalker still reckons that these shifts may well happen without too much deleterious effects. Banking analysts and think-tank researchers have to think up scenarios to justify their existences.
In the real world s**t happens as they say, and people and nations accommodate and get on with life as best as possible, without all the doomsday scenarios panning out.
