The Economist is asking that very question. And its conclusion?:
So it seems very unlikely that any of these banks will emigrate soon. Still, inside them the idea of self-imposed exile has risen in salience: from a bluff to a plan B.
Yeh, yeh. Like lots of people I know say they might retire one day, but it looks like it’s forever postponed.
When The Economist thinks they’re calling bluff and can find no evidence that any of them have done any real planning the one realistic conclusion is they’re here for a foreseeable future that’s so long we need not take any such comments seriously.
