What students do

  • Identify what makes a cartel a cartel and place OPEC's size, headquarters, and market share inside that definition
  • Explain why cartels are inherently unstable, using the swing producer's role in holding OPEC together
  • Trace three real breaks in OPEC discipline, the 1985 Saudi flood, the 2014 shale price war, and the 2020 COVID cut
  • Read three real charts on OPEC's market share, quotas, and prices, then write a briefing memo recommending U.S. policy

What it covers

  • Why Saudi Arabia's role as the swing producer is the one thing that has held OPEC together for 65 years
  • The three times OPEC discipline actually broke, and how the U.S. shale boom changed what OPEC can still do to prices
  • Explicit collusion, OPEC's formal agreement, next to the tacit kind, and why the Sherman Antitrust Act can't touch either one on Vienna soil
  • OPEC+ and its 2020 production cut, the largest in the cartel's history

Learning targets

  • Identify what a CARTEL is (a formal agreement among competing producers to limit output and raise prices), name OPEC's founding year (1960), headquarters (Vienna), and current size (12 members controlling about 37% of global crude oil)
  • Define CARTEL, PRODUCTION QUOTA, CARTEL CHEATING, COLLUSION (explicit vs tacit), OPEC+, SWING PRODUCER, and STRATEGIC PETROLEUM RESERVE and explain why cartels are inherently unstable
  • Read three real charts (OPEC's 1960-2024 global market share, OPEC member quota vs actual production in 2024, and oil prices at seven major OPEC events) and write a Final Briefing Memo recommending what the U.S. should do about OPEC's market power

What OPEC Is and Why It Matters

OPEC was founded on September 14,                in Baghdad.

OPEC is headquartered in                , Austria.

OPEC has                member nations today.

OPEC controls about                percent of global crude oil.

From the activity

1. Meera asks you to write the opening definition for the memo. A formal agreement among competing producers to limit total output and raise the market price above the competitive level is called a                 .

Why this matters

OPEC's members meet in Vienna and agree on how much oil to produce and what price that should bring, coordination that would send U.S. oil executives to federal prison under the Sherman Antitrust Act. The arrangement has lasted 65 years because Saudi Arabia keeps absorbing the overproduction everyone else is tempted to cheat with.

Students picture a cartel as one company setting prices at will, so the three real breaks in OPEC's discipline, the 1985 Saudi flood, the 2014 shale war, and the 2020 COVID cut, correct that fast. A cartel is really a coalition tempted to cheat on itself, which is why the closing memo reads like real policy work.

From one teacher to another

This one puts students on Meera Agarwal's cartel and market structures team at the U.S. Energy Information Administration, working the same question EIA analysts actually work: if everyone in a cartel agrees to keep prices high, why does someone always cheat? They build the cartel definition off OPEC itself, then chase the cheating incentive straight to Saudi Arabia, since the whole 65-year arrangement only survives because one country is willing to be the swing producer absorbing everyone else's overproduction. I built the timeline around three real moments OPEC's discipline broke down entirely, the 1985 Saudi flood, the 2014 shale price war, and the 2020 COVID cut, because a cartel that's always fought amongst its members is a much more accurate picture than a cartel that just sets prices at will. They finish by reading three real charts and writing a briefing memo recommending what U.S. policy should actually do about it.
