"The Bank of England was never going to rock the boat with an interest rate rise, given static economic conditions and a continued lack of direction on Brexit," Laith Khalaf, a senior analyst at Hargreaves Lansdown wrote in a note.
"(But) with the Fed now striking a more dovish pose as it also sees rising downside risks in the global economy, we shouldn't entirely rule out the possibility the next interest rate move may be downwards."
