Money markets price out a BOE rate hike next year after Raab's resignation
As mentioned here, it's more to do with the fact that Raab's resignation presents a very real possibility that an uncertain outcome will take place once parliament rejects the meaningful vote next month.
That only leaves us with a possibility of a disorderly Brexit, a second referendum, or a general election. All of which doesn't really constitute in scenarios that would help provide the BOE with the confidence to tighten policy further.
