Are we heading for ‘perfect storm’ in commodity production and prices? Certainly the prices of many commodities have soared in recent months. These include the prices of foodstuffs such as dairy products, cooking oils and cereals, crude oil, cotton, metals and many other raw materials. The overall world commodity price index has risen by 28% in the past 12 months. The following are some examples of specific commodities:

Price rises in the 12 months to February 2011

• Wheat 62%
• Maize 59%
• Coffee 70%
• Beef 39%
• Sugar 46%
• Palm kernal oil 142%
• Soybean oil 50%
• All food price index 32%
• Crude oil 20%
• Cotton 132%
• Fine wool 55%
• Softwood timber 25%
• Iron ore 78%
• Copper 29%
• Tin 55%
• All metals index 58%
• Rubber 79%.

The problems are both short term and long term, and on both the demand and supply sides; and the effects will be at micro, macro and global levels. Some hard choices lie ahead.

The following webcast, articles and reports explore both the current position and look into the future to ask whether rising commodity prices are likely to continue or even accelerate.

The first link is to a BBC World Debate which considers the following issues: “Is scarcity of natural resources a serious challenge for developing and advanced economies? How great is the risk that scarcity might lead to conflict, both within and between nations? Might a scramble for resources lead to a retreat from globalisation and to greater protectionism?”

  1. Identify the various factors that are causing rises in commodity prices. In each case state whether they are supply-side or demand-side factors.
  2. How can the price elasticity of demand and supply, the income elasticity of demand and the cross-price elasticity of demand be used to analyse the magnitude of the price rises?
  3. To what extent are rising food prices the result of (a) short-term (i.e. reversible) factors; (b) long-term trends?
  4. Why are food prices in the shops rising faster in the UK than in many other countries?
  5. To what extent is the future of food security and prices and moral issues?
  6. Why may current oil price rises become an opportunity for the future?
  7. What might be the respective roles be of government, business and consumers in responding to natural resource constraints?

In a statement to the House of Commons on 9 February 2011, the Chancellor announced that banks would extend their new lending to SMEs (Small and Medium-Sized Enterprises) from £179 billion in 2010 to £190 billion in 2011. An important question is the extent to which this initiative, which forms part of a series of initiatives in conjunction with the banking sector known as Project Merlin, will impact on economic activity.

Let’s begin by thinking about the role that credit plays in an economy. Firstly, it serves a short-term role by enabling individuals and firms to ‘bridge the gap’ between their income and their spending. Secondly, it can, depending on the size and terms of the credit, help to fund longer-term investments. In the case of firms, for instance, it can help to fund capital projects such as an expansion of premises or the installation of new equipment or production processes.

The extension of credit is the main source of growth in the money supply. If the credit which is extended by financial institutions is spent it increases economic activity. The size of the increase in economic activity will depend on how many times the credit is passed on from one firm or individual to the next. In other words, it depends on the velocity of circulation of money – often referred to simply as V. If the initial credit funds a series of purchases and the recipients of these monies, i.e. those from whom the purchases are made, then use their increased deposits to fund purchases themselves, the expansion could be sizeable.

There is every indication that the additional credit for SMEs will be welcome and it seems reasonable to assume that this will positively impact on spending. But, by how much is not entirely clear. This is what fascinates me about macroeconomics, but, perhaps understandably, may well frustrate others! Once the payments for the purchases made using the newly available credit become new deposits, how will these recipients respond? Will other credit-constrained firms use this liquidity to engage in purchases themselves? But, what if these recipients use the monies to increase or rebuild their own financial wealth? In this last scenario – a pessimistic scenario – the velocity of circulation will increase relatively little and economic activity little too.

The corporate sector, of course, does not exist in isolation of other sectors of the economy and, in particular, of the household sector. As some of the income from the expanded credit flows to them in the form of factor payments (i.e. wages and profits) – though by how much is itself debtable – how will they respond? Again will credit-constrained households look to spend? Alternatively, will they hold on to these liquid balances perhaps using them as buffer-stock savings? This is not an unrealistic possibility given the leverage of households and the need to rebuild wealth, especially so in times of incredible economic uncertainty? But, who knows!

So while Merlin may have waved his wand, the full extent of its impact, though probably positive, is far from clear. Time will tell. Isn’t macroeconomics wonderful!
