Mark Carney faces a heavy workload at the Bank of England Next year, the Bank will become the most powerful unelected body in Britain, with control of interest rates and financial supervision. Not only will it be able to decide what mortgage rate borrowers pay but also, if it judged a bubble was developing, whether banks should lend at anything other than exorbitant rates at all. Carney will be the man that makes the biggest overhaul in the Bank's 318-year history happen. He will have to manage the conflicts between the Monetary Policy Committee that sets rates and the Financial Policy Committee (FPC) which decides when to rein in the banks. He will also oversee the Prudential Regulatory Authority (PRA), which must push through decrees from the FPC. He will have to deal with the tricky assimilation of FSA staff into the Bank - two bodies with radically different cultures - and change the culture at the Bank itself. Free-thinking has suffered under Sir Mervyn King, who is said to have brooked little dissent, which led to a culture where staff "filtered" their opinions to what superiors would like to hear. MPs are pushing for greater accountability from the Court, the Bank's internal governance body, and more transparency. Carney is considered best placed to deliver just such a cultural overhaul. The Bank is also being pressed to open up its forecasting assumptions to outside scrutiny, to help to explain why its track record has been worse than the average private-sector economics consultancy. But first Carney will have to appoint his team. A new powerful role of chief operating officer is being created to bash heads together and ensure proposals turn into actions. Catherine Brown, the Bank's human resources director , is considered a favourite for the role. Carney's three deputy governors will also have to be decided, though they will appointed by the Chancellor. Charlie Bean, deputy governor for monetary policy, has agreed to stay an extra year until 2014 to help smooth the transition and Andrew Bailey is expected to become the deputy in charge of the PRA. The big question is about Paul Tucker, deputy governor for financial stability, whom Carney beat to the top job. The two are said to be friends and have a strong working relationship at the Financial Stability Board, but Tucker may decide to move on. Andy Haldane and Paul Fisher are likely internal candidates, though Carney has been critical of Haldane in the past. Perhaps the biggest challenge of all, though, will be unwinding the £375bn of quantitative easing.
