Tag: credibility of monetary policy

Although the Monetary Policy Committee (MPC) of the Bank of England is independent in setting interest rates, until recently it still had to follow a precise remit set by the government. This was to target inflation of 2% (±1%), with interest rates set to meet this target in 24 months’ time. But things have changed since the new Governor, Mark Carney, took up office in July 2013. And now things are not so clear cut.

The Bank announced that it would keep Bank Rate at the current historically low level of 0.5% at least until unemployment had fallen to 7%, subject to various conditions. More generally, the Bank stated that:

The MPC intends at a minimum to maintain the present highly stimulative stance of monetary policy until economic slack has been substantially reduced, provided this does not entail material risks to price stability or financial stability.

This ‘forward guidance’ was designed to provide more information about future policy and thereby more certainty for businesses and households to plan.

But unemployment has fallen rapidly in recent months. It fell from a 7.7% average for the three months May to July 2013 to 7.1% for the latest available three months (September to November 2013). And yet there is still considerable slack in the economy.

It now, therefore, looks highly unlikely that the MPC will raise Bank Rate as soon as unemployment falls below 7%. This then raises the question of how useful the 7% target has been and whether, if anything, it has created further uncertainty about future MPC decisions.

The following still appears on the Bank of England website:

The MPC intends at a minimum to maintain the present highly stimulative stance of monetary policy until economic slack has been substantially reduced, provided this does not entail material risks to price stability or financial stability.

But this raises two questions: (a) how do you measure ‘economic slack’ and (b) what constitutes a substantial reduction?

So what should the Bank do now? What, if any, forward guidance should it offer to the markets? Will that forward guidance be credible? After all, credibility among businesses and households is an important condition for any policy stance. According to Larry Elliott in the first article below, there are five options.

Questions

  1. What data would you need to have in order to identify the degree of economic slack in the economy?
  2. Why is it difficult to obtain such data – at least in a reliable form?
  3. Why might the issuing of the forward guidance last July have itself contributed to the fall in unemployment?
  4. Why is it difficult to obtain such data – at least in a reliable form?
  5. Why is credibility an important requirement for policy?
  6. Why may LFS unemployment be a poor guide to the degree of slack in the economy?
  7. Discuss the relative merits of each of the five policy options identified by Larry Elliott.

The Bank of England was granted independence to set interest rates back in 1997. This is known as instrument independence. However, the remit is set by the government and so it does not have goal independence. Amongst the policy announcements on Budget day (Wed 20 March), the government detailed amendments to the Bank’s remit. In particular, the remit now more explicitly acknowledges that, in exceptional circumstances, the Bank might need to pay more attention to output variability.

Despite the amendments to its remit, the Bank of England continues to have a forward-looking operational inflation rate target of 2 per cent (with a range of tolerance of up to 1 percentage point). The MPC therefore sets the Bank Rate, i.e. the rate at which it engages in short-term lending to financial institutions, to affect general interest rates in the economy. In turn, the level of interest rates is assumed to affect the level of aggregate demand and, hence, the rate of demand-pull inflation as well as inflation rate expectations.

A key economic benefit of delegating interest rate decisions to the Monetary Policy Committee (MPC) is thought to be lower inflation rate expectations. By granting the Bank of England operational or instrument independence, inflation announcements have a credibility that they would not if monetary policy was under the control of elected politicians. So why change the inflation rate remit?

The government remains of the view that inflation rate targeting has served the UK well, despite inflation being persistently above target for the past three years (see chart: click here for a PowerPoint). However, it has sought to clarify how the Bank of England might be expected to behave in exceptional circumstances when the economy is buffeted by shocks and disturbances, such as those that it has faced following the financial crisis of the late 2000s. The government argues that in such circumstances the output volatility that could result by ensuring that inflation remains on target could be undesirable. Therefore, the MPC should give consideration to the volatility of output that targeting inflation would cause in such exceptional circumstances.

The amended remit says that in setting monetary policy the MPC should communicate to the public the trade-offs that are inherent in meeting its forward-looking inflation rate target. Therefore, during exceptional times, the Bank may communicate that the volatility of output resulting from returning inflation to target would be so large that it is prepared to keep monetary policy looser than it otherwise would. This could mean indicating a time-frame over which it would be expected to keep interest rates lower than otherwise. By communicating this, it would in effect be looking to affect peoples’ expectations and, importantly, their behaviour. The prospect of prolonged low interest rates, such as those currently being experienced, might encourage greater expenditure, especially as a result of lower borrowing costs – though of course this is not guaranteed!

The Governor will continue to write an open letter to the Chancellor of the Exchequer if inflation moves away from the target by more than 1 percentage point in either direction. However, in a change to the previous remit, this will be done in conjunction with the minutes of the MPC meeting that follow the publication of the official inflation figures by the Office for National Statistics. By publishing the letter alongside the minutes, it gives the MPC more time to consider its strategy and to give due consideration to the trade-offs in returning inflation to the target. If inflation remains more than 1 percentage point above or below the target the Governor will need to write a further letter after three months. This letter would be alongside the minutes of the third subsequent meeting of the MPC.

Some commentators argue that the amended remit is merely a reflection of the current reality. In other words, the remit is being rewritten in a way which reflects how the MPC is currently making its interest rate decisions. Others are concerned that what was a simple and clear objective is now not the case and that this may have implications for the credibility of monetary policy. Whatever the rights and wrongs, Wednesday’s announcement was an important development in the history of central bank independence in the UK.
