With droughts and poor harvests in both North America and in Russia and the Ukraine, there are worries that food prices are likely to see sharp rises in the coming months. This is clearly bad news for consumers, especially the poor for whom food accounts for a large proportion of expenditure.
But it’s also bad news more generally, as higher food prices are likely to have a dampening effect on the global economy, struggling to recover from five years of low or negative growth. And it’s not just food prices. Oil prices are rising again. Since mid June, they have risen by nearly 25%. This too is likely to have a dampening effect.
Another contributing factor to rising food prices is a response, in part, to rising oil prices. This is the diversion of land from growing food to growing crops for biofuels.
G20 countries held a conference call on 28 August to discuss food prices. Although representatives decided against an emergency meeting, they agreed to reassess the situation in a few weeks when the size of the US harvest would be clearer. If the situation proved as bad as feared, then the G20 would call an emergency meeting of the Rapid Response Forum, to consider what could be done.
But is the sole cause of rising food prices a lack of production? Are there other problems on the supply side, such as poor distribution systems and waste? And what about the role of demand? How is this contributing to long-term increases in food prices? The articles consider these various factors and what can be done to dampen food prices.

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.

Questions
- Why have crude oil prices fallen to their lowest level for 17 months?
- How can the concepts of income elasticity of demand, price elasticity of supply and price elasticity of demand help to explain the magnitude of the fall in crude oil prices?
- Would a fall in inflation linked to a fall in commodity prices be a fall in cost-push or demand-pull inflation? Explain.
- What are the macroeconomic implications of the fall in crude oil prices?
- What factors are likely to have significant impact on crude oil prices in the coming months
- Why is it difficult to predict crude oil prices over the coming months?
The UK’s trade deficit narrowed in March to £2.74bn from £2.95bn in February. The goods deficit fell just slightly to £8.56bn from £8.59bn, but the services surplus rose more substantially to £5.83bn from £5.64bn.
So was this a sign of the UK economy’s relative weakness holding back the demand for imports? Or was it a sign of a recovering export sector, especially in services?
And what of the coming months? What will be the effect of a growing crisis in the eurozone on (a) the sterling exchange rate, (b) the rate of economic growth outside the UK and (c) UK economic growth? And what will be the effect of these on the demand for imports and exports and on the trade balance? The following articles examine the issues.

- Why did the UK experience its first trade surplus in cars since 1976?

- What has been happening recently to the sterling exchange rate? How will this impact on the UK’s balance of trade? How will the size of this impact depend on the price elasticity of demand and supply for imports and exports?
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 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?
