Tag: CPI inflation

UK CPI inflation rose to 3.1% in November. This has forced Mark Carney to write a letter of explanation to the Chancellor – something he is required to do if inflation is more than 1 percentage point above (or below) the target of 2%.

The rise in inflation over the past few months has been caused largely by the depreciation of sterling following the Brexit vote. But there have been other factors at play too. The dollar price of oil has risen by 32% over the past 12 months and there have been large international rises in the price of metals and, more recently, in various foodstuffs. For example, butter prices have risen by over 20% in the past year (although they have declined somewhat recently). Other items that have seen large price rises include books, computer games, clothing and public transport.

The rate of CPI inflation is the percentage increase in the consumer prices index over the previous 12 months. When there is a one-off rise in prices, such as a rise in oil prices, its effect on inflation will only last 12 months. After that, assuming the price does not rise again, there will be no more effect on inflation. The CPI will be higher, but inflation will fall back. The effect may not be immediate, however, as input price changes take a time to work through supply chains.

Given that the main driver of inflation has been the depreciation in sterling, once the effect has worked through in terms of higher prices, inflation will fall back. Only if sterling continued depreciating would an inflation effect continue. So, many commentators are expecting that the rate on inflation will soon begin to fall.

But what will have been the effect on real incomes? In the past 12 months, nominal average earnings have risen by around 2.5% (the precise figures will not be available for a month). This means that real average earnings have fallen by around 0.6%. (Click here for a PowerPoint of the chart.)

For many low-income families the effect has been more severe. Many have seen little or no increase in their pay and they also consume a larger proportion of items whose prices have risen by more than the average. Those on working-age benefits will be particularly badly hit as benefits have not risen since 2015.

If inflation does fall and if real incomes no longer fall, people will still be worse off unless real incomes rise back to the levels they were before they started falling. That could be some time off.

Questions

  1. Apart from CPI inflation, what other measures of inflation are there? Explain their meaning.
  2. Why is inflation of 2%, rather than 0%, seen as the optimal rate by most central banks?
  3. Apart from the depreciation of sterling, what other effects is Brexit likely to have on living standards in the UK?
  4. What are the arguments for and against the government raising benefits by the rate of CPI inflation?
  5. If Europe and the USA continue to grow faster than the UK, what effect is this likely to have on the euro/pound and dollar/pound exchange rates? What determines the magnitude of this effect?
  6. Unemployment is at its lowest level since 1975. Why, then, are real wages falling?
  7. Why, in the light of inflation being above target, has the Bank of England not raised Bank Rate again in December (having raised it from 0.25% to 0.5% in November)?

The latest figures from the ONS show that UK inflation rose to 2.3% for the 12 months to February 2017 – up from 1.9% for the 12 months to January. The rate is the highest since September 2013 and has steadily increased since late 2015.

The main price index used to measure inflation is now CPIH, as opposed to CPI. CPIH is the consumer prices index (CPI) adjusted for housing costs and is thus a more realsitic measure of the cost pressures facing households. As the ONS states:

CPIH extends the consumer prices index (CPI) to include a measure of the costs associated with owning, maintaining and living in one’s own home, known as owner occupiers’ housing costs (OOH), along with Council Tax. Both of these are significant expenses for many households and are not included in the CPI.

But why has inflation risen so significantly? There are a number of reasons.

The first is a rise in transport costs (contributing 0.15 percentage points to the overall inflation rate increase of 0.4 percentage points). Fuel prices rose especially rapidly, reflecting both the rise in the dollar price of oil and the depreciation of the pound. In February 2016 the oil price was $32.18; in February 2017 it was $54.87 – a rise of 70.5%. In February 2016 the exchange rate was £1 = $1.43; in February 2017 it was £1 = $1.25 – a depreciation of 12.6%.

The second biggest contributor to the rise in inflation was recreation and culture (contributing 0.08 percentage points). A wide range of items in this sector, including both goods and services, rose in price. ‘Notably, the price of personal computers (including laptops and tablets) increased by 2.3% between January 2017 and February 2017.’ Again, a large contributing factor has been the fall in the value of the pound. Apple, for example, raised its UK app store prices by a quarter in January, having raised prices for iPhones, iPads and Mac computers significantly last autumn. Microsoft has raised its prices by more than 20% this year for software services such as Office and Azure. Dell, HP and Tesla have also significantly raised their prices.

The third biggest was food and non-alcoholic beverages (contributing 0.06 percentage points). ‘Food prices, overall, rose by 0.8% between January 2017 and February 2017, compared with a smaller rise of 0.1% a year earlier.’ Part of the reason has been the fall in the pound, but part has been poor harvests in southern Europe putting up euro prices. This is the first time that overall food prices have risen for more than two-and-a-half years.

It is expected that inflation will continue to rise over the coming months as the effect of the weaker pound and higher raw material and food prices filter though. The current set of pressures could see inflation peaking at around 3%. If there is a futher fall in the pound or further international price increases, inflation could be pushed higher still – well above the Bank of England’s 2% target. (Click here for a PowerPoint of the chart.)

The higher inflation means that firms are facing a squeeze on their profits from two directions.

First, wage rises have been slowing and are now on a level with consumer price rises. It is likely that wage rises will soon drop below price rises, meaning that real wages will fall, putting downward pressure on spending and squeezing firms’ revenue.

Second, input prices are rising faster than consumer prices. In the 12 months to February 2017, input prices (materials and fuels) rose by 19.1%, putting a squeeze on producers. Producer prices (‘factory gate prices’), by contrast, rose by 3.7%. Even though input prices are only part of the costs of production, the much smaller rise of 3.7% reflects the fact that producer’s margins have been squeezed. Retailers too are facing upward pressure on costs from this 3.7% rise in the prices of products they buy from producers.

One of the worries about the squeeze on real wages and the squeeze on profits is that this could dampen investment and slow both actual and potential growth.

So will the Bank of England respond by raising interest rates? The answer is probably no – at least not for a few months. The reason is that the higher inflation is not the result of excess demand and the economy ‘overheating’. In other words, the higher inflation is not from demand-pull pressures. Instead, it is from higher costs, which are in themselves likely to dampen demand and contribute to a slowdown. Raising interest rates would cause the economy to slow further.

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.

Questions

  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?

First the good news. Employment is rising and unemployment is falling. Both claimant count rates and Labour Force Survey rates are down. Compared with a year ago, employment is up 279,092 to 29,869,489; LFS unemployment is down from 7.87% to 7.69%; and the claimant count rate is down from 4.7% to 4.0%.

Now the bad news. Even though more people are in employment, real wages have fallen. In other words, nominal wages have risen less fast than prices. Since 2009, real wages have fallen by 7.6% and have continued to fall throughout this period. The first chart illustrates this. It shows average weekly wage rates in 2005 prices. (Click here for a PowerPoint of the chart.)

The fall in real wages is an average for the whole country. Many people, especially those on low incomes, have seen their real wages fall much faster than the average. For many there is a real ‘cost of living’ crisis.

But why have real wages fallen despite the rise in employment? The answer is that output per hour worked has declined. This is illustrated in the second chart, which compares UK output per worker with that of other G7 countries. UK productivity has fallen both absolutely and relative to other G7 countries, most of which have had higher rates of investment.

The falling productivity in the UK requires more people to be employed to produce the same level of output. Part of what seems to be happening is that many employers have been prepared to keep workers on in return for lower real wages, even if demand from their customers is falling. And many workers have been prepared to accept real wage cuts in return for keeping their jobs.

Another part of the explanation is that the jobs that have been created have been largely in low-skilled, low-wage sectors of the economy, such as retailing and other parts of the service sector.

But falling productivity is only part of the reason for falling real wages. The other part is rising prices. A number of factors have contributed to this. These include a depreciation of the exchange rate back in 2008, the effects of which took some time to filter through into higher prices in the shops; a large rise in various commodity prices; and a rise in VAT and various other administered prices.

So what is the answer to falling real wages? The articles below consider the problem and some of the possible policy alternatives.

Letter writing has, in many walks of life, rather gone out of fashion. For instance, many of us of a slightly older disposition remember how putting pen to paper was an important part of courtship and the building of relationships. Well, one modern-day couple who are getting very used to an exchange of letters is the Governor of the Bank of England and the Chancellor of the Exchequer. The latest inflation numbers from the Office for National Statistics show that the annual rate of CPI inflation for July was 3.1%. While the inflation rate is down from the 3.2% recorded in June it remains more than 1 percentage point above the government’s central inflation rate target of 2%. Consequently, Mervyn King will again be writing to the Chancellor to explain why this is the case.

Since the turn of the year, the annual rate of CPI inflation has, with the exception of February, been consistently above 3%. Even February was a narrow escape for the Governor because inflation came in at exactly 3%! Another way of putting the recent inflation record into perspective is to note that over the first seven months of 2010 the average annual rate of CPI inflation has been 3.3%.

The slight fall in July’s annual inflation rate is attributed, in part, to falls during July in the prices of second-hand cars and petrol whereas these prices were rising a year ago. Furthermore, the average price of clothing and footwear fell by some 4.9% between June and July of this year as compared with a fall of 3.2% in the same period a year ago. The result is that the annual rate of price deflation for clothing and footwear went from 1.4% in June to 3.1% in July.

Of course, within the basket of consumer goods price patterns can vary significantly. One significant upward pressure on July’s overall annual inflation rate was the price of food and non-alcoholic beverages, especially vegetables. The average price of food and non-alcoholic beverages rose by 1% between June and July which has seen the annual rate of price inflation for food and non-alcoholic beverages rise from 1.9% in June to 3.4% in July.

The fact that July shows inflation running in excess of 3% will surprise very few. In the latest Inflation Report the Bank of England reports that the Monetary Policy Committee’s view is that ‘the forthcoming increase in VAT was expected to keep CPI inflation above the 2% target until the end of 2011’. The Committee then expects what it describes as a ‘persistent margin of spare capacity’ to force inflation to fall back. But, the Committee also feels that the prospects for inflation are ‘highly uncertain’. Therefore, it is difficult to gauge just how many more letters will be passing across London between the Governor and the Chancellor in the coming months. Nonetheless, it would be probably be advisable for the Governor to make sure that he has a sufficient supply of postage stamps at his disposal, just in case!
