On October 6, 1973 — Yom Kippur — Egypt and Syria launched a surprise attack on Israel. The US airlifted supplies to Israel. On October 17, Arab members of OPEC announced an oil embargo against the United States and other nations supporting Israel, cutting oil production 5% per month until Israel withdrew from occupied territories.
The impact was immediate and severe. Oil prices quadrupled from approximately $3 to $12 per barrel. In the US, lines formed at gas stations stretching city blocks. The Nixon administration imposed a national 55mph speed limit, daylight saving year-round, and the laughable WIN (Whip Inflation Now) campaign of voluntary restraint. Gas rationing based on license plate numbers followed.
The embargo ended in March 1974, but the price did not revert. The world had permanently re-priced oil risk. The geopolitical consequence was equally lasting: Henry Kissinger negotiated the petrodollar arrangement in 1974, in which Saudi Arabia agreed to price oil exclusively in dollars in exchange for US security guarantees — a system that underpinned dollar reserve status for the next 50 years and is now under strain.
The prevailing view before the reckoning
Oil was a purely economic commodity governed by supply and demand. OPEC was a cartel that would inevitably fracture on member self-interest. The embargo would end quickly because Arab producers needed revenue. Energy independence was not a national security priority. Inflation was controllable through standard monetary tools.
Commodity supply is a geopolitical weapon
The 1973 embargo was the proof of concept for resource nationalism. Every subsequent commodity shock — Russian gas to Europe, Chinese rare earths — references 1973 as the template.
Supply shocks defeat demand management
The Keynesian policy toolkit was built for demand-side inflation. Supply shocks — where prices rise because supply is constrained — cannot be cured by rate hikes without causing recession. Stagflation proved the old models wrong.
The petrodollar was a deliberate construction
Dollar reserve status after 1971 was not inevitable. It was engineered by Kissinger through the petrodollar arrangement. It can be un-engineered — which is what Saudi Arabia pricing oil in yuan discussions are about.
Energy vulnerability drives geopolitics for decades
The 1973 shock created the energy policy framework still in use: strategic petroleum reserves, fuel economy standards, nuclear investment debates, renewable energy research. Every energy policy debate since is downstream of October 1973.
