Carney said the financial system was in good shape for Brexit and that it could accommodate big shifts in financial markets depending on the outcome.
Asked whether he was concerned about hedge funds shorting the pound, Carney said the BoE was focused on the strength of the financial system as a whole, and that individual institutions' bets would not affect the wider economy.
