Changes in the price of oil have effects throughout the economy. And it’s not just on the obvious things, such as petrol prices, energy bills and rail, bus and air fares. Most companies are significantly affected by the price of oil, as oil is a key input into their production, whether for transporting their inputs or the goods they produce, or as plastics or other petrochemicals. This is why the price of oil receives so much attention: we’re all affected by it. You will have seen the price of petrol changing dramatically over the past year or so and this is largely due to changing oil prices. The price of oil peaked at $147 a barrel in July 2008 and fell as low as $32 a barrel in December 2008.

So what is it that causes these changes in oil prices and what does it mean for the world’s economies? Read the following articles, which discuss these issues, and look at recent developments in the oil industry.

The recession of the past few months has taken its toll on organic farmers. Until recently, the industry was booming as consumers switched to products perceived as greener, healthier and more ethically produced. Now, as many consumers are feeling the pinch, they are switching to cheaper foodstuffs. The resulting decline in demand for organic food has turned profit into loss for many organic farmers. According to the first of the linked articles below, at least two organic farmers are leaving the movement each week.

But what will happen as the economy recovers and people start turning back to organic products? Given that it takes some two years to convert to organic standards, there could be supply shortages next year.

Somali pirates have been much in the news recently with their high profile captures of oil tankers and other ships. The impact on shipping in the area is clear and this has disrupted trade in the region, but an unforeseen impact has been on the total worldwide catch of tuna. The Indian Ocean is one of the richest sources of tuna in the world and the pirate activity has led to a fall of around 30% in the total tuna catch.

  2. Suggest likely values for the price elasticity of demand and supply of tuna. Analyse the extent to which these values are likely to affect the price rise in the market for tuna.
  3. What substitutes are available for tuna? Assess the extent to which the availability of substitutes will affect the rise in the price of tuna.

Peak oil is an important concept for the oil market. Peak oil is the moment in time at which the maximum extraction rate of oil is reached. From this moment on, production will decline. Basic economics tells us that the oil price will tend to rise from then on (unless demand were to fall faster), but the complexities of the demand and supply for oil dictate that there will not be a simple inverse relationship between the supply of oil and the price. In the articles below George Monbiot interviews Faith Birol, the Chief Economist of the International Energy Agency and the Asia Times article looks at the extent to which world economies rely on oil for energy and other needs. Oil prices may be low at the moment and the market may be awash with excess oil and not enough demand for it, but this is a short term phenomenon; there is little doubt about the long-term direction of the price.
