The people of Scotland could use dried deer poo with currency markings carved into if they wished. Pound Punt Pint. the name is immaterial.
At this point what has been made clear by consensus of the 3 maim parties is that the pound sterling will not be available as legal tender in Scotland as it's currency. Effectively the Government of Scotland can create it's own pound and print as much of it as it wants (suicidal strategy but has happened). However, unless it is recognised by the traders on the world markets as a reliable currency underwritten by trust and substance (eg The German Government) it is pretty bits of paper.
Scottish bank notes are used in England and I have, over the years, used them many times. My bank (RBS) swap then for UK bank notes without a fuss when needed.
So will that be the same when (hopefully) Scotland leaves the union? Given the statements by the leaders of the political parties in power at Westminster now, it is the true unknown.
All paper currency is based on trust and the Governor of the Bank of England contracts that trust on "his" bank notes.
The current producers of the Scottish notes were required, historically, to lodge the equivalent amounts of 'English' bank notes in trust so that the Scottish notes had the 'trust" element needed to male the legal tender requirement real.
After the vote and the machinations that a successful Yes vote will bring, it can be predicted that chaos in the market must be avoided so Day 1 nothing changes, Day 364, however, could be a different matter. The remainder of the rUK will have gone through a general election and. given the potential UKIP spoiler vote, the dynamic could change.
Would I care to predict what 'may' happen, or be certain what will happen, as a should do? Not a chance..
As a whole now, the UK is a net importer of goods, including food, and payment for those goods is in Sterling or US Dollars
By using a siege mentality and not aligning the UK pound with a new Scottish pound then IMHO there is a huge risk for BOTH sides of the border to find imported goods only being supplied when a stable currency ($US) is used for payment. The ramifications of which could destabilise the "pound".
So could my musings really happen? Well it's another possibility but who really knows. If, however, we move to Scotland as planned, we will have a stash of Greenbacka for any eventuality BUT if all goes well DisneyWorld here we come (2017? 2018? 2019?,..…)
There is no value in Westminster destabilising the currency of an independent Scotland.
