The Grand Unifying Theory (and Practice) of Macroprudential Policy - PowerPoint PPT Presentation

The Grand Unifying Theory (and Practice) of Macroprudential Policy Mark Carney Governor, Bank of England 5 March 2020

Newtonian Mechanics… and Madness 2

Triumph (and Tragedy) of Monetary Policy Time inconsistency: resolved by society choosing preferred rate of inflation, then delegating operational responsibility to the monetary authority. MPC’s monetary policy remit: achieve price stability, defined by the Government as 12-month CPI inflation of 2%. Target is symmetric and applies at all times. Temporary deviations from target: recognised explicitly in remit since 2013; Bringing inflation back too rapidly could cause undesirable volatility in output and employment. 3

Advent of Macroprudential Policy Raison d’être is to ensure the financial system supports the economy by Lending to Ensuring downturns not households and made worse by businesses when unsustainable debt economic shocks burdens occur 7

Grand Unifying Theory of Macroprudential Policy To identify, monitor and take action to remove or reduce systemic risks with a Primary view to protecting and enhancing the resilience of the UK’s financial system objective Secondary Support the economic policy of Her Majesty’s Government, objective including its objectives for growth and employment. Not required or authorised to exercise functions in a way that would in its opinion be likely to have a significant adverse effect on the capacity of the financial sector to And… contribute to the growth of the UK economy in the medium or long term. 10

Monetary Policy vs Macroprudential Policy Clarity of objectives: MPC’s primary objective readily measured; FPC’s primary objective only estimated Impact on growth: MPC limited ability to influence trend growth. FPC policies potentially important for trend growth given permanent scarring from crises and influence on productive finance Time horizon: Longer horizon means discount rate more important for FPC 12

Optimal bank capital ratios balance impact on GDP-at-risk and trend growth Bank capital requirements balance reducing GDP-at-risk vs dampening investment and productivity. CCyB cushions shocks in a downturn, and matches resilience to risk environment. 24

Fund reforms possible macroprudential Divine Coincidence FPC’s principles to reduce structural liquidity mismatch in funds could increase investments in productive finance. 26

FPC’s principles deliver consistency between liquidity and redemption terms Funds should apply a pricing tool, a notice period or a combination of both that reflects the liquidity of their underlying assets 27

Reducing discount rate helps break Tragedy of the Horizon Government reduced discount rate by committing to Net Zero by 2050 and including climate risks in FPC remit. 28
