Mark Carney and his monetary advisors have cut the Bank of England’s interest to 0.25 percent, the lowest level in history. Officials led by the governor voted unanimously to reduce the benchmark rate as they struggle to anticipate the impact of Britain’s departure from the EU. They split over other elements of the stimulus, which expands the central bank’s balance sheet by 170 billion pounds ($223 billion) with purchases of gilts and corporate bonds, and a lending program for banks.
