As Brexit anecdotes go, it’s not a bad one. Three months ago at a City event, Charles Goodhart, a former Bank of England rate setter, was asked his opinion on the economic impact of the Brexit vote. Yes, official figures showed the UK economy expanded by 0.6pc in the final quarter of 2016 – a figure later revised up to 0.7pc. Yes consumer confidence was solid. And yes, the jobs market was close to full employment. But Goodhart then turned to the audience to ask how many had booked their summer holidays well in advance this year, in anticipation of future price rises. A sea of hands went up – one of them belonging to Sir Charlie Bean, former Bank deputy governor for monetary policy. “I know I have,” said Goodhart.
