The FT notes:
Gordon Brown said on Wednesday the world’s leading economies were close to agreeing a global bank tax, amid hopes in Downing Street that a deal can be concluded at the G20 summit in Canada in June.
Mr Brown believes that opinion has shifted decisively in favour of a globally co-ordinated tax after President Barack Obama’s move last month to raise $90bn (£57.7bn) from a US bank levy.
Let's hope it's a financial transaction tax then - a levy would kill off parts of the banking industry in a wholly unhelpful way. Financial transaction taxes won't.
Which is a pretty important issue to take into account, I suggest.
