Interesting timing from the Central Bank of Ireland's tweet machine this week.

On Tuesday afternoon, as everybody knows, European Union leaders converged for a crisis summit on Greece. The very future of the euro itself is at stake, we were told by some observers, as Greek prime minister Alex Tsipras was threatened with destitution, national bankruptcy and the divil 'n' all. At the very same time that our dear leaders were trying to save the currency, the Central Bank tweeted a call out for people to bring their old Irish punts into the bank for exchange.

There is probably no truth to the rumour that they’re trying to stock up just in case.
