What Is OPEC? How Oil Producers Set Global Prices

When crude oil prices rise on the international market, the effects can reach far beyond oil-producing countries. Transport costs can increase, businesses may spend more on energy, and governments can face pressure to manage inflation.

One organisation frequently mentioned whenever oil prices change is OPEC. Its production decisions can influence how much crude oil reaches the global market, affecting the balance between supply and demand.

But what exactly is OPEC, how does it operate, and can it decide how much oil should cost around the world?

What Is OPEC?

OPEC stands for the Organisation of the Petroleum Exporting Countries. It is an intergovernmental organisation established in Baghdad, Iraq, in September 1960 by five founding members: Iran, Iraq, Kuwait, Saudi Arabia and Venezuela.

Its headquarters is in Vienna, Austria. The organisation brings together oil-producing countries to coordinate petroleum policies and work towards stable oil markets.

OPEC’s stated objectives include coordinating members’ oil policies, helping to stabilise oil markets and ensuring a regular supply of petroleum to consumers while supporting stable revenues for producers.

Rather than operating as an oil company, OPEC provides a platform where member governments discuss production levels and other developments affecting the petroleum industry.

Nigeria is a member of OPEC and joined the organisation in 1971. This makes the group particularly relevant to the country’s economy, government revenue and oil exports.

How Does OPEC Influence Global Oil Prices?

OPEC influences oil prices mainly through decisions about how much crude oil its members produce. These decisions can affect the amount of oil available to buyers worldwide.

However, the organisation does not simply announce a price that every producer and buyer must follow. International crude prices are determined by market conditions, including supply, demand and expectations about future events.

Here are the main ways OPEC can influence the market.

1. By Increasing or Reducing Oil Production

One of OPEC’s most important tools is adjusting production targets for participating members.

When oil producers supply more crude than the market needs, prices can come under pressure. If producers reduce output while demand remains strong, the available supply may tighten, potentially pushing prices higher.

For example, imagine the global market needs 100 million barrels of oil per day, but producers collectively supply 102 million barrels. If demand does not increase, the surplus could put downward pressure on prices.

If production falls while demand remains unchanged, the surplus may shrink or become a shortage, creating upward pressure on prices.

These figures are hypothetical and illustrate the principle rather than actual global oil-market data.

OPEC’s influence depends partly on whether its members implement agreed production targets and how other producers respond.

2. By Coordinating Decisions Among Oil Producers

OPEC members meet to discuss market conditions and agree on production policies. Such decisions can influence expectations about future oil availability.

When the organisation signals that production will be reduced, traders may anticipate tighter supply and adjust their buying and selling decisions. Prices can therefore move before the announced production changes fully take effect.

The reverse can happen when producers announce plans to increase output.

However, member countries have different economic interests, production capacities and budgetary needs. These differences can make agreement and implementation challenging.

3. Through OPEC+

OPEC+ is a wider cooperation framework involving OPEC members and participating oil-producing countries outside the organisation, including Russia.

The framework was established in 2016 to strengthen cooperation between OPEC and non-OPEC producers.

OPEC+ decisions can have a significant influence on global supply because they involve additional producers beyond OPEC’s membership.

However, OPEC and OPEC+ are not the same organisation. Not every country participating in OPEC+ is an OPEC member, and individual participants may have different production capacities and priorities.

4. By Influencing Market Expectations

Oil prices respond not only to the amount of crude currently being produced but also to expectations about future supply and demand.

If traders expect OPEC or OPEC+ to reduce production, they may anticipate a tighter market. If they expect production to increase, they may prepare for greater availability.

These expectations influence trading in crude oil futures, which are contracts linked to buying or selling oil at a specified price at a future date.

As a result, international oil prices can change following announcements, even before the physical supply of crude changes.

Does OPEC Set the Price of Oil?

No. OPEC can influence international oil prices, but it does not directly determine one fixed price for every barrel sold worldwide.

Crude oil is traded in global markets where prices respond to supply, demand, the quality of the oil, transport costs, geopolitical developments and other factors.

Two major benchmarks are Brent crude, widely used to price internationally traded oil, and West Texas Intermediate (WTI), a major US benchmark.

Producers and buyers often use these benchmarks as reference points when negotiating prices for particular crude grades.

OPEC’s production decisions can influence these benchmarks by changing expectations about global supply. However, prices can move in the opposite direction from what the organisation intends if other market forces are stronger.

For instance, production cuts may fail to lift prices substantially if global demand weakens or producers outside the group increase their output.

Similarly, prices can rise sharply during a supply disruption even if OPEC has not announced a production cut.

What Other Factors Affect Global Oil Prices?

OPEC is influential, but it is not the only force shaping the oil market.

Global Demand

When economic activity expands, factories, transport networks and businesses generally require more energy. This can increase demand for crude oil and petroleum products.

If demand grows faster than supply, prices may rise. A slowdown in economic activity can have the opposite effect.

Wars and Geopolitical Tensions

Conflicts involving oil-producing countries or important shipping routes can disrupt production, exports and deliveries.

Even the threat of disruption can raise prices because buyers worry about future shortages.

Production Outside OPEC

Countries outside OPEC, including the United States, produce substantial quantities of oil. Changes in their output can increase or reduce the supply available to the global market.

If non-OPEC producers increase production significantly, they can partly offset supply reductions by OPEC members.

Oil Inventories

Oil stocks held by governments, refineries and commercial operators can help absorb temporary supply disruptions.

When inventories are high, markets may be better positioned to withstand interruptions. When stocks are low, a disruption may have a greater effect on prices.

Shipping and Transportation Costs

Crude oil must be transported from production sites to refineries and other buyers. Higher freight rates, insurance premiums or restrictions on shipping routes can increase the cost of delivering oil.

These expenses can also affect the prices received by producers and paid by refiners.

Why OPEC Matters to Nigeria

Nigeria is a major oil-producing country, making developments in the international petroleum market important to its economy.

Crude oil exports generate foreign exchange, while petroleum-related revenue contributes to government finances. Changes in international oil prices can therefore affect public revenue, budget planning and foreign-exchange inflows.

When crude prices rise, Nigeria may earn more from each barrel exported, assuming production volumes, export arrangements and other costs remain comparable.

However, higher prices do not automatically guarantee higher total revenue. Oil production disruptions, theft, operational costs and changes in export volumes can reduce the benefits.

Lower oil prices can put pressure on government revenue and foreign-exchange earnings, particularly when production and other revenue sources do not compensate for the decline.

Nigeria’s participation in OPEC also means that production agreements can influence its output decisions. These arrangements must be considered alongside the country’s production capacity and domestic economic needs.

Does Higher Crude Oil Price Automatically Mean Higher Petrol Prices?

Not necessarily.

Although crude oil is an important input in petrol production, the pump price of petrol also depends on refining costs, international product prices, shipping, exchange rates, distribution expenses, taxes and domestic pricing arrangements.

In Nigeria, the naira’s exchange rate and the cost of importing or supplying refined petroleum products can significantly influence local fuel prices.

Consequently, an increase in international crude prices does not always translate into an immediate or equal increase in petrol prices. The relationship depends on the wider supply chain and prevailing market conditions.

Can OPEC Control Oil Prices Forever?

OPEC can influence supply, but it cannot fully control the global oil market.

Its effectiveness depends on factors such as members’ production capacity, compliance with agreed targets, demand growth and the response of competing producers.

Changes in energy technology, fuel efficiency and the adoption of alternative energy sources can also influence long-term oil demand.

Meanwhile, geopolitical tensions and disruptions to production or shipping can create conditions that are difficult for any producer group to manage.

For these reasons, OPEC’s decisions are an important part of oil-price analysis, but they should not be viewed in isolation from other market developments.

Final Thoughts

OPEC is one of the most influential organisations in the international oil industry because its members can affect the amount of crude oil supplied to global markets.

By coordinating production policies and working with other participating producers through OPEC+, the organisation can influence supply expectations and contribute to changes in oil prices.

However, it does not set a single global oil price. Demand, competing producers, geopolitical events, inventories and shipping costs all play important roles.

For Nigeria, understanding OPEC is particularly useful because international crude prices affect export earnings, government revenue and the wider economy.

Ultimately, the price of oil reflects the interaction of producers, buyers and market conditions around the world, with OPEC playing an important but not exclusive role.
