As the global recession began to take hold during 2008, so many commodity prices plummeted. Oil prices fell from over $140 per barrel in mid July 2008 to around $35 per barrel by the end of the year (a mere quarter of the price just 6 months previously). From early 2009, however, prices started rising again and have continued to do so during 2010. By mid April 2010, the price of oil had risen to $85 per barrel.
And it’s not just oil prices that have been rising. The prices of metals such as copper, nickel and zinc have been soaring. Since the beginning of February 2010, copper prices have risen by 18%, zinc prices by 20% and nickel prices by 46%. As the article from the Independent states:
The Office for National Statistics said that the input price index for materials and fuels purchased by the manufacturing industry rose 10.1 per cent in the year to March and rose 3.6 per cent between February and March alone. The ONS added that prices of imported materials as a whole, including imported crude oil, rose 4.4 per cent between February and March.
Much of the explanation for this has been the global recovery. But while raw material prices have been rising, grain prices have been relatively steady and recently have fallen. So how can this be explained? The answer, as always with commodity prices, lies with demand and supply, as you will see when you read the following articles.

Until recently, gold prices had been rising. If you watch TV, you can hardly have failed to notice the adverts offering cash back for your gold. After peaking on the 2nd December 2009, however, at about $1220 an ounce, the price of gold fell almost $100 in just four trading days.
Over the past two months, we’ve seen a fluctuating US dollar and a fluctuating price of gold. In the news item ‘A golden age‘ we looked at the factors that led to a rising price of gold and one key factor was the weakness of the dollar. However, the dollar’s downward spiral appears to have halted, at least for the time being.
Figures for US GDP were higher than expected, with increases in economic activity in the 4th quarter of 2009. This may partly explain why the dollar strengthened, and prices of gold began to fall, as people began investing in US assets. And it was not just gold that fell – there was speculation that the price of copper too would fall as investors switched to US assets.
Then, at the end of January the dollar fell against most currencies and a variety of refined products recovered from recent losses incurred. This pause in the demand for the dollar may cause gold prices to increase once again, as traditionally, gold moves inversely to Greenback. Although the price of gold was down 1.1% for the month of January, speculation that the US budget deficit could be as big as $1.6 trillion could mean further support for gold and testing times to come for the dollar.
At the beginning of February 2010, the US dollar weakened against the euro, as investors favoured a return to riskier assets in search of higher returns, encouraged by signs of strengthening manufacturing in key economies. With the global economy coming out of the worst downturn in decades, will the dollar begin to strengthen?

Questions
- How is the price of gold determined? Use a diagram to illustrate this process. If there is a change in demand or supply for gold, what factors will affect the extent of the price change?
- Why does a strengthening dollar imply a lower price of gold?
- Why will a large US budget deficit support gold, but test the dollar?
- How is the exchange rate determined? What factors affect the supply of dollars and the demand for dollars?
- What are the main factors that could explain why there has been a rise in the dollar? Could speculation play a role?
Gold prices have been soaring in recent months. In fact, such is the demand for the precious metal that Harrods has just started selling gold bars. “The Knightsbridge department store yesterday began selling bars of pure Swiss gold bullion as part of a range that is being displayed in a miniature vault on the lower ground floor” (see eighth link below).
In November 2008, gold was trading at around $750 per ounce; by October 2009, the price had reached $1080 per ounce. Why has this happened? Will the trend continue? What does it signify about the world economy – both its current and likely future state? The following articles look at the causes and effects of this new ‘golden age’.

Questions
- Use a demand and supply diagram to illustrate the change in the price of gold between November 2008 and October 2009. Does the explanation lie largely of the demand or the supply side? Use the concepts of price elasticity of demand and supply to explain the size of the price change for any given shift in demand or supply.
- How is the price of gold related to the strength of the US dollar?
- Explain whether gold is a commodity or a currency (or both).
- What is meant by the ‘head and shoulders pattern’ in the price of gold? Is the use of ‘patterns’ a good way of predicting future prices? Give reasons why it may or may not be.
Tea prices have soared in recent months. Explanations can be found on both the demand and supply side. But while this might be bad news for tea drinkers, the news is more mixed for tea growers. So just what are the causes and consequences of the price rises? The following linked articles look at the issues.

Questions
- Identify the factors on the demand and supply sides that have led to the rise in tea prices. Draw a diagram to illustrate your answer.
- Under what circumstances will farmers benefit from a rise in tea prices? What is the relevance of the market price elasticity of demand to your explanation?
- If the price of tea in the shops rises, will this necessarily mean a rise in the price to tea growers and in the wages of workers on tea plantations? Explain using concepts of competition and market power.
- What will be the effect of using more land for growing tea on (a) the price of tea and (b) the incomes of tea growers?
