And yet in the last few weeks the UK government managed to cause a run on sterling. If they were using the Euro then that wouldn't have happened / limited effect and Mrs Truss could potentially have implemented her tax changes. Not that I support that, just pointing out there are also downsides to a sovereign monetary policy. I personally think that being in the bigger club, the EU trade zone and Euro, would be better for Britain. Greece is a cautionary tale, but not necessarily a currency one. Yes, they had limited options after everything blew up, but they were heading in that direction because they kept taking loans and the loans kept being given. If they had been able to devalue their currency its not actually clear that would have solved the problem - doing so also requires tight fiscal policy. Iceland did it, with a tight fiscal policy.
