What is OPEC?

OPEC (Organization of the Petroleum Exporting Countries) is an intergovernmental organization of oil-producing nations. Founded in 1960, its primary goal is to coordinate petroleum policies and stabilize oil markets.

OPEC members collectively produce about 30% of the world's crude oil, giving the organization significant influence over global oil prices.

OPEC Member Countries

OPEC currently has 13 member countries:

RegionMembers
Middle EastSaudi Arabia, Iran, Iraq, Kuwait, UAE
AfricaAlgeria, Libya, Nigeria, Congo, Gabon, Equatorial Guinea
South AmericaVenezuela
AsiaNone currently

Saudi Arabia is the largest producer and de facto leader of OPEC, often setting the tone for production decisions.

How OPEC Influences Prices

OPEC's primary tool for influencing oil prices is production quotas. By agreeing to produce more or less oil collectively, OPEC can shift global supply:

Cutting Production

When oil prices are low, OPEC may agree to reduce production. Less supply with steady demand pushes prices higher. This helps member countries maintain revenue despite selling fewer barrels.

Increasing Production

When prices are very high, OPEC may increase production to bring prices down. This prevents demand destruction (consumers switching to alternatives) and maintains market stability.

OPEC+ Explained

In 2016, OPEC formed an alliance with non-OPEC oil producers called OPEC+. Key non-OPEC members include:

  • Russia (the most significant partner)
  • Mexico
  • Kazakhstan
  • Malaysia
  • Bahrain
  • Azerbaijan

OPEC+ coordinates production cuts and increases together, controlling approximately 40% of global oil production. This gives the group even more market influence than OPEC alone.

OPEC Meetings and Decisions

OPEC holds regular meetings where members discuss market conditions and production policy:

  • OPEC Conference: Meets at least twice yearly (usually June and December)
  • OPEC+ Meetings: Coordinate with non-OPEC allies
  • Technical Committees: Monitor market conditions between meetings

Market participants closely watch these meetings. Unexpected decisions can cause significant price volatility.

Production Quotas in Practice

Each OPEC member has a production quota - a maximum number of barrels they agree to produce. However, compliance varies:

  • Strong compliers: Saudi Arabia typically adheres strictly to quotas
  • Weak compliers: Some members have historically exceeded quotas
  • Exemptions: Countries facing hardships may receive temporary exemptions

Saudi Arabia sometimes acts as a "swing producer," adjusting its own production to compensate for others' non-compliance.

OPEC's Historical Impact

OPEC has been central to several major oil market events:

1973 Oil Embargo

Arab OPEC members imposed an oil embargo on countries supporting Israel. Oil prices quadrupled, causing a global economic crisis.

1986 Price Collapse

Saudi Arabia increased production to regain market share, causing prices to collapse from $30 to $10 per barrel.

2014-2016 Price War

OPEC refused to cut production despite a supply glut, attempting to drive US shale producers out of business. Prices fell below $30.

2020 Price War and COVID

A brief Saudi-Russia price war combined with COVID-19 demand destruction caused unprecedented market chaos, with WTI briefly going negative.

Limits of OPEC's Power

OPEC's influence has limits:

  • US Shale: American producers can quickly increase output when prices rise
  • Compliance Issues: Member countries don't always follow quotas
  • Demand Changes: Economic slowdowns reduce oil demand regardless of supply
  • Alternative Energy: Growth in renewables and electric vehicles reduces long-term oil demand

OPEC must balance these factors when making production decisions.

Following OPEC News

To stay informed about OPEC:

  • Monitor announcements before and after OPEC+ meetings
  • Watch for compliance reports showing actual vs. agreed production
  • Pay attention to comments from Saudi Arabia's energy minister
  • Note any tensions between major members (especially Saudi Arabia and Russia)

  • OPEC+ includes additional non-OPEC partners like Russia
  • The group influences prices by adjusting production quotas
  • Saudi Arabia is the most influential member
  • OPEC's power has limits, particularly from US shale production
  • OPEC meetings are significant market-moving events
