Central bank planning: Unconventional monetary policy and the price of bending the yield curve
Central banks have increasingly used communication to guide market actors’ expectations of future rates of interest, inflation, and growth. However, aware of the pitfalls of (financial) central planning, central bankers used to draw a line by restricting their monetary policy interventions to short-term interest rates. Longer-term rates, they argued, reflected decentralised knowledge and should be determined by market forces. By embracing forward guidance and quantitative easing (QE) to target long-term rates, central banks have crossed that line. While consistent with the post-1980s expansion of the temporal reach of monetary policy into the future, these unconventional policies nevertheless mark a structural break – the return of hydraulic macroeconomic state agency, refashioned for a financialised economy.
