Fuelling the absence of inflation

The latest inflation figures, as detailed in February’s Consumer Price Inflation Statistical Bulletin, show that the annual rate of CPI inflation hit zero in February. This is down from 0.3 per cent in January. While inflation is now well outside the 1-3 per cent target range that the Bank of England is charged with meeting, perhaps a more pertinent question is whether the UK is teetering on the brink of deflation – and the risks that may carry.

To get a better sense of the latest inflation picture we need to delve deeper into the numbers and look at the patterns in the prices that make up the overall Consumer Price Index. Interestingly, these shows that five of the 12 principal product groups that make up the index are currently experiencing price deflation.

As explained in Consumer Price Inflation: The 2015 Basket of Goods and Services, produced by the ONS, around 180,000 prices quotations are collected each month for around 700 representative items. These goods and services fall into one of 12 broad product groups. These include, for example, food and non-alcoholic beverages and transport.

The items included in each of the 12 product groups are reviewed once a year so that the chosen items remain representative of today’s spending patterns. A monthly price index is calculated for these 12 broad groupings, known as divisions, and for sub-categories of these. For example meat is a category within food and non-alcoholic beverages. The overall CPI is a weighted average of the 12 broad groupings.

The annual rate of CPI inflation in February 2015 was zero. This means that the price of the representative basket of goods and services was unchanged from its level in February 2014. As Chart 1 shows (click here for a PowerPoint of the chart), the annual rate of CPI inflation series goes back to January 1989 and this is the first time it has fallen to zero. Its average over this period is in fact 2.7 per cent. The recent fall is quite stark with the rate of CPI inflation in June 2013 close to the top-end of the Bank of England’s target range at 2.9 per cent.

Of the 12 product groups, five constitute 10 per cent or more of the overall weight of the CPI index. These weights are dependent on the relative level of expenditure comprised by each division.

Chart 2 shows the annual rates of inflation for these five groups (click here for a PowerPoint of the chart). The most heavily-weighted component is transport (14.9%), which includes the price of fuel and passenger transport. Here we observe deflation with prices 2.7 per cent lower year-on-year in February. This is the fourth consecutive month where its annual rate of price inflation has been negative.

The second most heavily-weighted component within the CPI index is recreation and culture (14.7%), which includes games, toys and audio-visual equipment. Here too we see the emergence of deflation. In February 2015 prices were 0.8 per cent lower than in February 2014. Deflation is most prevalent in the fifth most heavily-weighted component (11.0%): food and non-alcoholic drinks. The price for this division of the CPI was 3.3 per cent lower in February 2015 as compared with February 2014. In nine of the last ten months the price of food and non-alcoholic drinks, helped by aggressive price competition in the grocery sector, has been lower year-on-year.

February also saw a negative annual rate of inflation emerge for the first time in the CPI division capturing furniture and household equipment and appliances (-0.3 per cent). Further, miscellaneous services, which include personal care and personal effects (e.g. jewellery) saw an annual rate of deflation for the eight consecutive month. The annual rate of inflation for miscellaneous services stood at -0.4 per cent in February. However, February did see an upturn in price inflation for clothing and footwear with prices 1.7 per cent higher than a year earlier while the price of alcohol and tobacco was 3.8 per cent higher year-on-year.

The detailed inflation numbers do reveal the extent to which many CPI divisions are already characterised by deflation. It is interesting to note that in A Comparison of Independent Forecasts published monthly by HM Treasury, the forecast for the final quarter of 2015 is for the annual rate of CPI inflation to be running at 0.8 per cent. An important reason for this is that the effect of falling fuel prices from November 2014 will begin to drop out of the year-on-year inflation rate calculations. The removal of this effect should help to prevent the specter of deflation provided that peoples’ inflationary expectations remain anchored, i.e. exhibit stickiness. If these were to be revised down, however, this would further contribute to downward pressure on prices since input price inflation – including wage inflation – would again be expected to fall.

  1. Explain the difference between a decrease in the level of prices and a decrease in the rate of price inflation. Can the rate of price inflation rise even if price levels are falling? Explain your answer
  2. Explain what is meant by deflation.
  3. In what ways might deflation affect the behaviour of people? What effect could this have on the macroeconomy?
  4. Why do you think policy-makers, such as the Monetary Policy Committee, would be interested in the inflation rates within the overall CPI inflation rate?
  5. What factors do you think lie behind the fall in the transport component of the CPI?
  6. Explain why the rate of inflation would be expected to rise in the late autumn, a year on from when the transport component of the CPI began falling.
  7. Does the possibility of deflation mean that inflation rate targeting has failed?
