inflation target has already led to suboptimal economic performance, and could seriously hinder further recovery. Simon Wren-Lewis of Oxford University, for example, has argued that ‘to continue with inflation as the primary target could jeopardise a macroeconomic policy that focuses on strong growth, and quickly offsets any negative shocks’.19 He notes that the Fed’s dual mandate allows it to prioritize maximum unemployment and look through temporary increases in inflation. Indeed, the Fed has recently reviewed its approach to the target and declared that in future it will adopt an ‘averaging’ methodology, which allows it to tolerate overshoots to ‘catch up’ with past shortfalls.
Presenting the new policy, Jerome Powell, chair of the Fed since 2018, noted that, in an environment where inflation expectations are very low, interest rates ‘decline in tandem’. As a result, ‘we would have less scope to cut interest rates to boost unemployment during an economic downturn, further diminishing our capacity to stabilize the economy through cutting interest rates. We have seen this adverse dynamic play out in other major economies.’ To prevent such a dynamic establishing itself in the US, the Fed decided that in future ‘employment can run at or above real-time estimates of its maximum level without causing concern’ and ‘following periods when inflation has been running below 2 percent, appropriate monetary policy will likely aim to achieve inflation moderately above 2 percent for some time’.20
The Bank of England argues that the UK inflation target regime, with its focus on inflation at a two-year time horizon, allows it the flexibility to look through temporary overshoots, as it did in 2010. It argues furthermore that since 2010 there has been no undershoot of the target, as there has been in the US and the Eurozone. But, as Wren-Lewis points out, interest rates have been at or close to their lower bound for some time, and the policy tool then available, QE, ‘is just too unreliable compared to interest rates or fiscal policy’.
Ed Balls and colleagues at Harvard Business School have argued that in these circumstances a closer nexus between monetary and fiscal policies is required. They recommend that the Governor should be mandated to write to the Chancellor suggesting the scale of fiscal stimulus they think is needed when interest rates are at their lower bound.21 Support for that approach came from Olivier Blanchard, the former Chief Economist of the IMF, who argues that if interest rates remain lower than the growth rate, and if monetary policy is constrained by the zero lower bound, it makes sense to run fiscal deficits to sustain demand, even if this leads to a further increase in debt.22
So far, neither the Bank of England itself nor the Treasury has shown any signs of being interested in amending the policy framework in this way. If the post-Covid recovery is again sluggish, as the post-GFC recovery was, the question of monetary and fiscal policy coordination will rise up the agenda, but the Bank of England will certainly resist any change which puts its monetary policy independence at risk.
