Speculation is rife in the City that the Bank of England may be minded to cut interest rates following a similar move by the US.
But if incoming governor Andrew Bailey was thinking of following the Federal Reserve’s lead with an emergency announcement of his own, he was not letting on.
Instead, he hinted to MPs on the Treasury Select Committee that any cut would need to be properly discussed among the Monetary Policy Committee.

As a result, the FTSE 100 closed the day up 97.39 points, or 1.45%, at 6,815.59.
The leading index is still a long way off the highs of two weeks ago, but most of the worst falls from last Friday have been reversed.
David Madden, CMC Markets analyst, said: “The positive move has been influenced by speculation that we might see interest rate cuts from the Bank of England as well as the European Central Bank in the near-term.
“Some traders feel the central banks might sit on their hands for a while and see how things play out. In light of the Fed’s emergency rate cut yesterday (Tuesday), the chatter about other central banks cutting too is likely to do the rounds for a while.”
