In two recent blogs we have analysed the headache facing the Monetary Policy Committee, given the persistence of inflationary pressures in the UK economy, in deciding whether to raise interest rates. In Food for thought, Elizabeth Jones describes how, despite the weakness of aggregate demand, cost pressures have fuelled inflation while John Sloman in Time for a rise in Bank Rate looks at the difficult judgement call for the MPC in risking a marked dampening of aggregate demand by raising rates while, on the other hand, failing to dampen inflationary expectations by not raising rates. In this blog Dean Garratt analyses some of the latest inflation figures as detailed in the latest Consumer Price Indices Statistical Bulletin. In particular, he focuses on the inflation rates within the overall consumer price inflation rate.
You might be wondering what we mean when we refer to inflation rates within the overall inflation rate. In answering this we need to consider how the Office for National Statistics goes about estimating the Consumer Price Index (CPI) and the CPI inflation rate (further details are available in Consumer Price Indices – A Brief Guide produced by the ONS). In order to compile the Consumer Price Index (CPI), each month an organisation collects on behalf of the ONS something in the region of 110,000 prices quotations for around 560 items. But, the key point is that these goods and services fall into one of 12 broad product groups which are referred to as level 1 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. Once the price information for our representative goods and services has been collected, the prices are compared with their levels in the previous January and the change recorded. These changes are then aggregated in both each product group and across all groups. The price changes are aggregated by weighting them according to the typical share of household spending that each good or service represents. This process is repeated each month in the year so as to always calculate the aggregate change in prices since January. The final step is to link the price changes with those from earlier years to form one long price index, both for each product group and for the overall shopping basket, so that at one arbitrary moment in time the index takes a value of 100.
Once we have our price indices we can calculate annual rates of price inflation. The annual rate of CPI inflation in December 2010 is recorded at 3.7%. This means that the Consumer Price Index was 3.7% higher in December 2010 than it was December 2009. Similarly, the annual rate of CPI inflation in November 2010 of 3.3% means that consumer prices rose by 3.3% between November 2009 and November 2010. Across 2010 as a whole the CPI rose by 3.3%, so in excess of the Bank of England’s inflation rate target range, and significantly up on the 2.2% across 2009. The Bank has a symmetrical inflation rate target of 2% plus or minus 1 percentage point (you may want to read more about the Bank’s Monetary Policy Framework).
Let’s look to delve deeper because price indices are also available for product groups at two lower levels known as level 2 and level 3 product groups. For example, from within the food and non-alcoholic beverages group there is a price index wholly for food and within this one for vegetables. Again annual rates of price inflation can be found for level 2 and level 3 product groups.
If we consider food and non-alcoholic beverages we find an annual rate of price inflation for December of 6.1%. This was its highest annual rate since May 2009. Across 2010 as a whole we find that prices rose by 3.4%, very much in accordance with the overall CPI inflation rate. Inflationary pressures within this category are not new with 2008 seeing prices rises by 9.1% as compared with 3.6% for the overall CPI inflation rate. Over the past 5 years, food and non-alcoholic beverage inflation has typically been running at an annual rate of 5% while overall consumer price inflation has been running at 2.8%.
If we now focus on food alone, we find an annual rate of food price inflation in December of 5.7%. While this is a little lower than with the inclusion of non-alcoholic beverages, it is nonetheless a full 2 percentage points above the overall CPI inflation rate. Across the year as a whole food price inflation comes in bang on 3% highlighting the extent of the inflationary pressures in more recent months. This, however, still falls some way short of the pressures seen in 2008 when food prices rose by 10.1%. If we drop to level 3 to focus on groups within the food category we find inflation rates for oils and fats of 11%, for fish of 9% and for fruit of 8.6%.
Within the 12 broad groups the highest annual rate of price inflation is currently to be found for transport where the annual rate of price inflation in December was 6.5%. Across 2010, transport prices rose by 8.3% which compares a tad unfavourably with the 0.8% increase seen in 2009. If we drop down to the level 3 groups within this category we can trace the source of the price pressures more readily. The cost of air passenger transport in December was up over 12 months by 13.5% and, you may not be surprised to learn, the cost of fuel and lubricants was up by 12.9%.
We finish by noting the only level 1 category to see prices fall across 2010: clothing and footwear. This product group saw prices fall by 1% in 2010. But, even here price pressures have emerged. Between April 1992 and August 2010 clothing and footwear consistently recorded annual rates of price deflation. Since September this has ceased with positive annual rates of inflation. The annual rate of inflation for clothing and footwear in December was estimated at 1.5%. Perhaps those socks in my bottom drawer really will have to last me just a little bit longer!

One of the interesting things about the recent recession was the dilemma that it posed for governments. As aggregate demand fell, unemployment rose, incomes fell, which reduced demand further and so national output began to decline. Obviously there were many other factors contributing to this decline, in particular the housing market, but the long and the short of it is, aggregate demand was falling. With the AD curve shifting inwards, we would expect the average price level to fall at the same time: i.e. inflation doesn’t tend to be much of a problem during a recession. It is this fact that posed something of a dilemma. In the recession, not only was aggregate demand low, but inflation was rising. The explanation for this: in large part due to rising commodity prices – a supply-side shock. Governments had to deal with low national output and inflation: this combination made policy changes much more complex.
While prices for many goods and commodities did fall significantly after their peak in 2008, there has been a gradual rise again and there seems to be no end in sight. Headline food prices, in particular, have increased almost to their 2008 levels, although in real terms prices are still lower. Onions in India; cabbage, pork and mackerel in South Korea; chillies in Indonesia – the list goes on. The rapidly rising prices of these basic foodstuffs has, in many cases, led to emergency government intervention. However, there are fewer concerns this time round, as many hope that the causes of these higher prices are not just the increases in demand but crucially temporary supply shocks. Bloomberg’s Businessweek Assistant Managing Editor, Sheelah Kolhatkar, said:
There are a lot of reasons [for rising prices]. Weather is cited as a big one. There’s been sort of freak weather in different parts of the world. Russia experienced a drought. There are floods in Australia. There’s been sort of freezing weather in Florida. Our own Midwest experienced flooding earlier this year. And because the market for a lot of these food commodities is global, when something strange happens somewhere, that can affect a crop.
On the other hand, there are growing concerns at the timing of this inflation: the developed world has barely escaped from recession. How is it that inflation can already be a problem? Furthermore, with loose monetary policy in many countries, rising food and commodity prices could continue for some time.
An interesting question to consider is which countries will be affected the most? In Britain, like other developed countries, food consumption accounts for between 15 and 20 per cent of a household budget. However, in developing countries, food can take up between 50 and 75 per cent of a houshold budget, so any rise in food prices is disastrous.
What does it mean for the recovery? Well, if food (a necessity) is increasing in price, households have little choice but to pay the higher prices. This means they have less disposable income for other goods, hence aggregate demand may be adversely affected. The following articles will hopefully give you some ‘food for thought’!

For most people, buying a new car is a luxury and in times of hardship it is a luxury that many cannot afford. Sales of new cars did grow during 2010 by 1.8% compared to the previous year, although the end of the car scrappage scheme in March 2010 did see a fall in sales. Sales went from being 19.9 per cent up on 2009 in the first half of the year, to being 13.8 per cent down for the remainder of 2010. On top of this, they are predicted to fall by some 5% over the coming 12 months.
Part of the explanation of this trend is the VAT rise. While an extra 2.5% is hardly noticeable on many every day items (as we saw when VAT was reduced to 15%), it will have a much larger effect on more expensive items, such as cars.
It was expected that people thinking of buying a new car would try to beat the VAT rise and so car firms hoped for a surge in sales during December. However, this did not occur and with VAT at 20% during 2011, car prices will rise: a £15,000 car will cost an extra £320. Another contributing factor to the lower than expected sales in December was the snow. Retail sales in December collapsed by 37.5%, where as fleet sales, which are less likely to be affected by the adverse weather rose by 5.1%. Similar patterns were seen in Spain, Italy and France, but in Germany sales were up by 7% on the year from December 2009.
The good news for the UK car industry is that the second half of 2011 is expected to see growth, so there may be some recovery. Furthermore, UK-built cars have seen a rise in sales – up by 17%. Finally, as petrol prices continue to rise, it is hoped that this might encourage people to trade in their less efficient old cars for more fuel-efficient new cars. This will certainly be an industry to watch over the next few months.

It is the Bank of England’s responsibility to ensure that inflation remains on target. They use interest rates and the money supply to keep inflation within a 1% band of the inflation target set by the government = 2%. However, for the past 12 months, we have had an inflation rate above the 3% maximum and this looks set to continue. Official figures show that the CPI inflation rate has risen to 3.3% in November, up from 3.2% in October 2010 – above the inflation target. There was also movement on the RPI from 4.5% to 4.7% during the same months. The ONS suggests that this increase is largely down to record increases in food, clothing and furniture prices: not the best news as Christmas approaches. It is not just consumers that are facing rising prices, as factories are also experiencing increasing costs of production, especially with the rising cost of crude oil (see A crude story). Interest rates have not changed, as policymakers believe prices will be ‘reined in’ before too long.
However, the government expects inflation to remain above target over the next year, especially with the approaching increase in VAT from 17.5% to 20%. As this tax is increased, retail prices will also rise and hence inflation is likely to remain high. There is also concern that retailers will use the increase in VAT to push through further price rises. A report by KPMG suggests that 60% of retailers intend not only to increase prices to cover the rise in VAT, but to increase prices over and above the VAT rise.
Despite the planned VAT rise spelling bad news for inflation, it could be the spending cuts that offset this. As next year brings a year of austerity through a decrease in public spending, this could deflate the economy and hence bring inflation back within target. However, there are suggestions that more quantitative easing may be on the cards in order to stimulate growth, if it appears to be slowing next year. The Bank of England’s Deputy Governor, Charles Bean said:
“It is certainly possible that we may well want to undertake a second round of quantitative easing if there is a clear sign that UK output growth and with it inflation prospects are slowing,” Bean told a business audience in London.”
The following articles consider the rising costs experienced by firms, the factors behind the inflation and some of the likely effects we may see over the coming months.

The prices of grains and other foodstuffs are rising rapidly. Wheat prices rose some 40 per cent in July and have continued to rise rapidly since. In June wheat futures were trading at around 450 US cents/bushel. By early September, they were trading at around 700 US cents/bushel. Global food prices generally rose by 5% over the two months July/August. And it’s not just food. Various other commodity prices, such as copper and oil, have also increased substantially.
At the beginning of September there were three days of food riots in Mozambique in protest against the 30% rise in the price of bread. Seven people were killed and 288 were injured. On 2 September Russia announced that it was extending a ban on wheat exports for another 12 months following a disastrous harvest. In Pakistan, the floods have destroyed a fifth of the country’s crops. Drought in Australia and floods in the Canadian prairies have reduced these countries’ grain production.
In response to the higher prices and fears of food riots spreading, the United Nations has called a special meeting on 24 September to bring food exporters and importers together to consider “appropriate reactions to the current market situation”. And yet, although global cereal production is down by some 5% on last year, it is still predicted to be the third largest harvest on record.
So what is causing the price rises? Is it simply a question of the balance of supply and demand and, if so, what has caused the relevant shifts in supply and/or demand? And what role does speculation play? The following articles look at the issues and at the outlook for commodity prices over the coming months.
Clearly changes in commodity prices affect the rate of inflation. The news item (Bank of England navigates choppy waters) amongst other issues looks at the outlook for inflation and the various factors influencing it.
