The Bank of England’s monetary policy is aimed at achieving an inflation rate of 2% CPI inflation ‘within a reasonable time period’, typically within 24 months. But speaking in Nottingham in one of the ‘Future Forum‘ events on 14 October, the Bank’s Governor, Mark Carney, said that the Bank would be willing to accept inflation above the target in order to protect growth in the economy.
“We’re willing to tolerate a bit of an overshoot in inflation over the course of the next few years in order to avoid rising unemployment, to cushion the blow and make sure the economy can adjust as well as possible.”
But why should the Bank be willing to relax its target – a target set by the government? In practice, a temporary rise above 2% can still be consistent with the target if inflation is predicted to return to 2% within ‘a reasonable time period’.
But if even if the forecast rate of inflation were above 2% in two years’ time, there would still be some logic in the Bank not tightening monetary policy – by raising Bank Rate or ending, or even reversing, quantitative easing. This would be the case when there was, or forecast to be, stagflation, whether actual or as a result of monetary policy.
The aim of an inflation target of 2% is to help create a growth in aggregate demand consistent with the economy operating with a zero output gap: i.e. with no excess or deficient demand. But when inflation is caused by rising costs, such as that caused by a depreciation in the exchange rate, inflation could still rise even though the output gap were negative.
A rise in interest rates in these circumstances could cause the negative output gap to widen. The economy could slip into stagflation: rising prices and falling output. Hopefully, if the exchange rate stopped falling, inflation would fall back once the effects of the lower exchange rate had fed through. But that might take longer than 24 months or a ‘reasonable period of time’.
So even if not raising interest rates in a situation of stagflation where the inflation rate is forecast to be above 2% in 24 months’ time is not in the ‘letter’ of the policy, it is within the ‘spirit’.
But what of exchange rates? Mark Carney also said that “Our job is not to target the exchange rate, our job is to target inflation. But that doesn’t mean we’re indifferent to the level of sterling. It does matter, ultimately, for inflation and over the course of two to three years out. So it matters to the conduct of monetary policy.”
But not tightening monetary policy if inflation is forecast to go above 2% could cause the exchange rate to fall further. It seems as if trying to arrest the fall in sterling and prevent a fall into recession are conflicting aims when the policy instrument for both is the rate of interest.

- Explain the difference between cost-push and demand-pull inflation.
- If inflation rises as a result of rising costs, what can we say about the rate of increase in these costs? Is it likely that cost-push inflation would persist beyond the effects of a supply-side shock working through the economy?
- Can interest rates be used to control both inflation and the exchange rate? Explain why or why not.
- What is the possible role of fiscal policy in the current situation of a falling exchange rate and rising inflation?
- Why does the Bank of England target the rate of inflation in 24 months’ time and not the rate today? (After all, the Governor has to write a letter to the Chancellor explaining why inflation in any month is more than 1 percentage point above or below the target of 2%.)
- What is meant by a zero output gap? Is this the same as a situation of (a) full employment, (b) operating at full capacity? Explain.
- Why have UK gilt yields soared in the light of a possible ‘hard Brexit’, a falling exchange rate and rising inflation?
