Commodity prices have been falling for the past three years and have reached a four-year low. Since early 2011, the IMF overall commodity price index (based on 2005 prices) has fallen by 16.5%: from 210.1 in April 2011 to 175.4 in August 2014. The last time it was this low was December 2010.
Some commodity prices have fallen by greater percentages, and in other cases the fall has been only slight. But in the past few months the falls have been more pronounced across most commodities. The chart below illustrates these falls in the case of three commodity groups: (a) food and beverages, (b) agricultural raw materials and (c) metals, ores and minerals. (Click here for a PowerPoint of the chart.)
Commodity prices are determined by demand and supply, and factors on both the demand and supply sides have contributed to the falls.
With growth slowing in China and with zero growth in the eurozone, demand for commodities has shown little growth and in some cases has fallen as stockpiles have been reduced.
On the supply side, investment in mining has boosted the supply of minerals and good harvests in various parts of the world have boosted the supply of many agricultural commodities.
But in historical terms, prices are still relatively high. There was a huge surge in commodity prices in the period up to the financial crisis of 2008 and then another surge as the world economy began to recover from 2009–11. Nevertheless, taking a longer-term perspective still, commodity prices have risen in real terms since the 1960s, but with considerable fluctuations around this trend, reflecting demand and supply at the time.
Identify specific demand-and supply-side factors that have affected prices of (a) grains; (b) meat; (c) metal prices; (d) oil.
Why is the demand for commodities likely to be relatively inelastic with respect to price, at least in the short term? What are the implications of this for price responses to changes in supply?
Why may there currently be a ‘buying opportunity’ for potential commodity purchasers?
What is meant by the ‘futures market’ and future prices? Why may the 6-month future price quoted today not necessarily be the same as the spot price (i.e. the actual price for immediate trading) in 6 months’ time?
How does speculation affect commodity prices?
How does a strong US dollar affect commodity prices (which are expressed in dollars)?
How may changes in stockpiles give an indication of likely changes in commodity prices over the coming months?
Distinguish between real and nominal commodity prices. Which have risen more and why?
How do real commodity prices today compare with those in previous decades?
When the rest of the developed world went into recession after the financial crisis of 2007/8, the Australian economy kept growing, albeit at a slightly lower rate (see chart 1: click here for a PowerPoint). Then as the world economy began to grow again after 2009, Australian grow accelerated. Partly this was the result of a strong growth in demand for Australian mineral exports, such as coal, iron ore and bauxite, especially from China and other east Asian countries.
But in 2013, Australian growth slowed and jobs grew by their lowest rate for 17 years. Employment actually fell by 22,600 in December and unemployment was only prevented from rising by a fall in the participation rate. The Australian dollar, which has been depreciating in recent months, fell further on the news about jobs, reaching its lowest level for over two years (see chart 2: click here for a PowerPoint).

The following articles look at the reasons behind Australia’s slowing growth and at possible reactions of the Australian government and the Reserve Bank of Australia (Australia’s central bank). They also look at the link between economic performance and policy on the one hand and the exchange rate on the other.

What determines the magnitude of the rise or fall in demand for Australian exports as the world economy grows or declines? How are the determinants of the price and income elasticities of demand for Australian exports relevant to your answer?
Oil prices have been falling in recent months. By early June they had reached a 17-month low. The benchmark US crude price (the West Texas Intermediate price) fell to $83.2 at the beginning of the month, and Brent Crude (the North Sea reference price for refining into petrol) fell to $97.7 (see chart). (For a PowerPoint of the chart below, click here.)
At the same time various commodity prices have also been falling. The IMF all commodities price index has fallen by 7.2% over the past 12 months and by 6.2% in May alone. Some commodities have fallen much faster. In the 12 months to May 2012, natural gas fell by 44%, wheat by 25%, lamb by 37%, Arabica coffee by 36%, coconut oil by 45%, cotton by 47%, iron ore by 23% and tin by 29%.
Although part of the reason for the fall in the price of some commodities is increased supply, the main reason is weak world demand. And with continuing problems in the eurozone and a slowdown in China and the USA, commodity price weakness is likely to continue.
So is this good news? To the extent that commodity prices feed through into consumer prices and impact on the rate of inflation, then this is good news. As inflation falls, so central banks will be encouraged to make further cuts in interest rates (in the cases where they are not already at a minimum). For example, the Reserve Bank of Australia cut its cash rate last week from 3.75% to 3.5%. This follows on from a cut from 4.25% on 1 May. In cases where there is no further scope for interest rate cuts (e.g. the US Federal Reserve Bank, whose interest rate is between 0% and 0.25%), then the fall in inflation may encourage a further round of quantitative easing.
But falling commodity prices are also a reflection of bad news, namely the low economic growth of the world economy and fears of turmoil from a possible Greek exit from the euro.
Update A day after this was written (9/6/12), a deal was agreed between eurozone ministers to provide support of up to €100 billion for Spanish banks. This helped to reduce pessimism about the world economy, at least temporarily. Stock markets rose and so too did oil prices, by around 1%. But if pessimism increases again, then the fall is likely to resume.

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.
In the past few weeks, the prices of gold and silver have been soaring and have hit all-time (nominal) highs. Over the past 12 months, gold has risen by 31%, while silver has risen by 149% and 64% since the start of February. Part of this reflects the general rise in commodity prices (see also). Oil is trading at around $125 per barrel, up 43% on a year ago; wheat is up 66%, maize by 114%, coffee (Arabica) by 118% and cotton by 122%.
Part of the reason for the rise in the price of precious metals, however, has been the weakness of the dollar. In such times, gold and silver are often seen as a ‘safe haven’ for investors.
So why have commodity prices been rising and why has the dollar been falling? What is likely to happen to the prices of gold and silver in the coming weeks and months? Is their meteoric rise set to continue? Will the ratio of the gold price to the silver price continue to fall? The following articles investigate.
Why have the prices of gold and silver risen so much recently?
Why has silver risen more than gold?
Why may higher rates of world inflation make investors turn to precious metals for investment?
How are future decisions by the Fed likely to affect the price of gold?
According to the efficient capital markets theory (strong version), the current price of a commodity should already reflect all knowable factors that are likely to affect the price? Does this mean that speculative buying (or selling) is pointless?
How is the price elasticity of supply of silver and gold relevant in explaining the magnitude of their price movements?
Commodity prices have been falling for the past three years and have reached a four-year low. Since early 2011, the IMF overall commodity price index (based on 2005 prices) has fallen by 16.5%: from 210.1 in April 2011 to 175.4 in August 2014. The last time it was this low was December 2010.
