Goldman Sachs' boss has admitted to making a mistake about the immediate hit Brexit would have on the UK economy, adding that he was surprised there hasn't "been a more dramatic effect" since the result in June 2016.
Lloyd Blankfein, who has hinted in the past that the City could lose out to rival EU cities in the wake of the vote, said: "I'm at least wrong in the fact I thought there would have been a worse outcome by now."
He has taken a series of potshots at Brexit, last year tweeting to his 90,000 followers: "Just left Frankfurt. Great meetings, great weather, really enjoyed it. Good, because I'll be spending a lot more time there.
The bank recently signed a new lease in Frankfurt that gives it capacity to seat up to 1,000 staff in the German city. Its new, larger London office is due to open next year.
Speaking to Politico, he said that the Wall Street banking giant might not have chosen to build the £1billion (NZ$1.93 billion) EU hub in London had it known about Brexit.
