Danni Hewson, AJ Bell head of financial analysis, said: "Although no one expects any surprises from central bankers in terms of their decision, it will be their tone and choice of words with the power to send any anticipated Santa rally hurtling in the other direction."
She pointed out "there’s a rather tight rope to walk as bankers try and keep confidence in check without squashing it entirely."
Back in London, and the early focus will be UK unemployment and average earnings figures, a key figure ahead of Thursday’s interest rate decision by the Bank of England.
