Fisher, speaking at the University of Warwick, said the responsibilities of the incoming Financial Policy Committee (FPC) – detecting and reducing threats to the financial system – were a “tough ask”.

“The UK economy is constantly subject to shocks and varying pressures, many of them from abroad, which cause fluctuations in economic activity,” he said.

“The job of policymakers is to recognise and assess such developments, and subsequently take actions to mitigate their impact.

“Once action is taken it then may need time – and we could be talking years – for the economy to respond fully. So expectations of maintaining financial stability continuously would be over-optimistic.
