Anyone investing in commodities over the past few weeks will have been in for a bumpy ride. During the first part of 2011, commodity prices have soared (see A perfect storm brewing?). This has fuelled inflation and has caused the Bank of England to revise upwards its forecast for inflation (see Busy doing nothing see also Prospects for Inflation).
But then in the first week of May, commodity prices plumetted. On the 5 May, oil prices fell by 7.9% – their largest daily amount since January 2009. Between 28 April and 6 May silver prices fell from $48.35 per ounce to just over $33.60 per ounce – a fall of over 30%. And it was the same with many other commodities – metals, minerals, agricultural raw materials and foodstuffs.
Many financial institutions, companies and individuals speculate in commodities, hoping to make money buy buying at a low price and selling at a high price. When successful, speculators can make large percentage gains in a short period of time. But they can also lose by getting their predictions wrong. In uncertain times, speculation can be destabilising, exaggerating price rises and falls as speculators ‘jump on the bandwagon’, seeing price changes as signifying a trend. In more stable times, speculation can even out price changes as speculators buy when prices are temporarily low and sell when they are temporarily high.
Times are uncertain at present. Confidence fluctuates over the strength of the world recovery. On days of good economic news, demand for commodities rises as people believe that a growing world economy will drive up the demand for commodities and hence their prices. On days of bad economic news, the price of commodities can fall. The point is that when undertainty is great, commodity prices can fluctuates wildly.

Questions
- Why did commodity prices fall so dramatically in early May, only to rise again rapidly afterwards?
- Why do commodity prices fluctuate more than house prices?
- What is the relevance of price elasticity of demand and supply in explaining the volatility of commodity prices?
- Under what circumstances is speculation likely to be (a) stabilising; (b) destabilising?
- To what extent are rising commodity prices (a) the cause of and (b) the effect of world inflation?
- If commodity prices go on rising every year, will inflation go on rising? Explain.
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.

Questions
- Use a supply and demand diagram to illustrate (a) what has been happening to wheat prices (b) what is likely to happen to wheat prices over the coming months?
- How relevant is the price elasticity of demand and supply and the income elasticity of demand to your analysis?
- What factors have caused the shifts in demand and/or supply of wheat and copper?
- What has been the role of speculation in the price rises? Is this role likely to change over the coming months?
- What is likely to happen to food prices in the shops over the coming months? Would you expect bread prices to rise by the same percentage as wheat? If so, why; if not, why not?
- If commodity prices generally rose by 5 per cent over the coming year, would you expect inflation to be 5 per cent? Again, if so, why; if not, why not?
Oil affects our everyday lives. Whether it’s to heat your house, to run your car or to work out production costs, the price of oil is important. Commodity prices are determined by the interaction of demand and supply and oil prices are no different. As demand and supply for products and for oil itself change, so will the price of oil. However, any changes in the price of this valuable commodity will also have effects on macroeconomic variables, such as inflation. From a high of $147 (£90) per barrel in July 2008, it fell to $30 by the end of the year. But since then it doubled to reach $60 by May and has been around the $70 mark since.
How have these fluctuations affected the economy? Should more be invested in extraction? Extracting oil is an expensive process and requires huge investment, which is problematic given the current recession and various funding issues. The following articles consider this problem, as well as the impact it is likely to have on our economic recovery.

Up until a year ago, milk and cheese prices were soaring woldwide (see Cheddar – the king of cheeses at £2000 per tonne). A surging world economy and rapidly growing demand from China and India were driving up commodity prices, including milk and milk-based producs. In the UK, average farmgate prices for milk had risen from 19 pence per litre (ppl) in 2006 to 27.4ppl by October 2008 (see here for data). Since then, however, as the global economy has plunged into recession, milk prices have fallen. By September 2009, the farmgate price had fallen by over 18 per cent to around 22.4ppl. With rising costs for fuel and cattle feed, many dairy farmers are now making a loss and are either quitting, or considering quitting, the industry.
It’s a similar story in Europe, North America and other dairy producing regions of the world. In Europe “the mood is turning sour. Last week 300 tractors dragged milk containers over fields in southern Belgium, dumping a day’s worth of production (see video). Similar protests were made in Germany, France, the Netherlands and Luxembourg. The crisis has driven many EU farmers into a ‘milk strike’, with thousands refusing to deliver to the industrial dairy conglomerates that produce everything from skimmed milk to processed cheese.”
So is this just market forces in action and will prices rise again as the world economy recovers? Or is it a reflection, in part, of the monopsony power of the supermarkets and the milk processing industry? The following articles look at the issues, both in the UK and the rest of Europe and in the USA.

Questions
- For what reasons are many dairy farmers now making a loss?
- For what reasons has the power balance in the wholesale milk market shifted towards milk purchasers (such as supermarkets) and away from farmers?
- How would a phased liberalisation of EU milk production help the UK’s dairy farmers?
- Discuss the likely effectiveness of the European Commission’ proposed measures to help dairy sector in short, medium and long term.
- What is likely to happen to milk prices over the next two years and what will be the likely effect on supply? Explain your answer and consider the relevance of price elasticity of supply.
- “Agriculture officials and farmers in Vermont, New Hampshire and Massachusetts have launched a program called Keep Local Farms. … Organizers say they hope to appeal to consumers’ growing taste for local foods” (see final linked article above). What determines the likely effectiveness of such ‘buy local’ movements? What incentives are there for people to buy local? If countries in general encourage people to buy local, is this a zero sum game? Explain.
Many primary commodity prices have fallen during the recession, but have recovered somewhat as the recession has bottomed out and hopes of a recovery have grown. So what will happen to commodity prices over the next few months and beyond, and what will determine the size of the price changes? The following linked articles look at these questions.
