Topic 9: 9.3 The global demand for oil is increasing, but supplies are unevenly available explained
Topic 9: 9.3 The global demand for oil is increasing, but supplies are unevenly available covers 2 specification points, including A.
Read the full explanation
How oil reserves and production are… and B. How oil supply and oil prices are affected…. Open a point below for its explanation and revision guidance.
a. How oil reserves and production are unevenly distributed and why oil consumption is growing (rising per capita GDP, rapid industrialisation in emerging economies).
This criterion asks you to explain two linked ideas: why oil is unevenly distributed, and why demand for it keeps growing. Keep reserves and production separate. Reserves are estimated amounts recoverable under current conditions, whereas production is the amount extracted in a year. The Middle East holds a large share of proven reserves, so supply is concentrated there, while other regions depend on different geology and technology. For demand, explain that rising per capita GDP lets people buy more cars, goods and energy-using services. Rapid industrialisation in emerging economies such as China and India adds demand for transport fuel, petrochemicals and power. Link each cause to its effect, then explain why uneven supply and growing demand together create the need for international trade.
b. How oil supply and oil prices are affected by changing international relations (conflicts, diplomatic relations) and economic factors (periods of recession versus boom, over or under supply).
This criterion asks how oil supply and oil prices respond to two kinds of change: international relations and economic conditions. Explain the mechanism, not just list events. Conflicts can disrupt supply by damaging production facilities or shipping routes, which tends to push prices up. Diplomatic relations matter when producer groups such as OPEC agree output quotas, because a decision to cut production reduces supply. Economic factors work through demand. In a boom, rising industrial activity increases demand and pushes prices up; in a recession, falling demand tends to lower them. Over-supply or under-supply sets the balance directly: a surplus lowers prices, as seen when US shale output expanded in the mid-2010s, while a shortfall raises them. State the direction of each change.
Your focus

Topic 9: 9.3 The global demand for oil is increasing, but supplies are unevenly available exam tips
Marking Points
- Distinguishes oil reserves (estimated recoverable amounts) from oil production (amount extracted in a given period).
- Explains that reserves are concentrated in a small number of regions, with the Middle East holding a large share.
- Explains that production is uneven because it depends on geology, extraction technology and investment, not only on reserves.
- Links rising per capita GDP to higher spending on cars, goods and energy-using services, which increases oil demand.
- Explains that rapid industrialisation in emerging economies raises demand for transport fuel, petrochemicals and electricity generation.
- Connects uneven supply and growing demand to the need for trade between producing and consuming countries.
- Explains that conflict can reduce supply by damaging production facilities or disrupting shipping routes, pushing prices up.
- Explains that diplomatic relations and producer agreements, such as OPEC output quotas, change how much oil is supplied.
- Explains that a boom increases demand for oil and tends to raise prices, while a recession reduces demand and tends to lower them.
- Explains that over-supply lowers prices and under-supply raises them.
- Uses a dated or named example to support at least one cause and its effect on price.
Examiner Tips
- 💡Plan your answer as two chains of cause and effect: one for distribution and one for consumption.
- 💡Use the bracketed prompts in the statement as a checklist, and make sure each one is covered by a clear sentence.
- 💡When an answer option mentions a country or region, check whether it is being used to show uneven supply or growing demand, and choose the option that gives the reason rather than only a location.
- 💡Structure your answer around the two categories in the statement: international relations and economic factors.
- 💡For each factor, write the chain of cause, effect on supply or demand, and effect on price, then check the direction of change.
- 💡When choosing between answer options, eliminate any that reverse the direction of price change before considering the details.
Common Mistakes
- Treats reserves and production as the same measure; keep them separate and define each one.
- Describes growing consumption without naming a cause; name rising per capita GDP or industrialisation and explain the link to demand.
- Lists countries with oil without explaining why supply is uneven; explain the geological and economic reasons for concentration.
- Treats conflict as having no effect on price; explain that disruption to supply usually raises prices.
- Describes a recession as raising prices; explain that falling demand tends to lower them.
- Lists events without linking them to supply or price; state the mechanism and the direction of change for each one.
