1) In the event of an Indy Yes result England (using the name to generalize) would let Scotland use the pound because it suits England, not because of benevolence towards Scotland. Without the Scots, England’s currency would be sorely weakened and that’s bad for the printing country. The events of the last few days in the forex market make it abundantly clear, quantifiably clear, that it suits England to have Scotland inside its currency zone (just the way it suited England to have the entire geographical island of Ireland inside the pound sterling zone for a full 300 years).
2) Seen Ecuador’s economic performance recently, Krugger? High GDP growth, low inflation, constantly improving balance sheet, and all by using the US Dollar. The change there hasn’t been in the currency, it’s been in the stronger attitude to leadership. Scotland may have a problem in Alex Salmond in the medium-term, but adopting the Pound is not the base issue.
