The queue around the block
Published 2 October 2026
You did not need to understand the Middle East to understand an empty tank.
During the 1973 Arab-Israeli war, Arab oil producers imposed an embargo against the United States in response to the US decision to resupply Israel and to gain influence over subsequent negotiations. Other targeted countries included the Netherlands, Portugal and South Africa. The measures combined restrictions on exports with production cuts. The State Department's historical account says oil prices first doubled and then quadrupled. US diplomatic history of the embargo.
Precision matters here. The embargo was an action by Arab producers, not a decision attributable without qualification to every OPEC country. The producing-country coalition behind a political restriction is not necessarily identical to the membership of the price-coordination organization. These overlapping clubs are easy to blur and dangerous to confuse.
The shock also did not arrive in an otherwise frictionless system. The same historical account identifies earlier disputes over pricing, the erosion of spare capacity in East Texas and changes to the dollar's exchange-rate regime as part of the background. A war supplied the trigger. Existing vulnerability made the trigger expensive.
For the importing countries, the problem was not only paying more. It was whether supply would arrive. For a government, fuel scarcity turns from an industry issue into a political issue because it interferes with daily mobility, production and household budgets. A price increase can be discussed in an economics lecture. A queue is an argument conducted in public.
The response had several layers. The United States introduced conservation measures and later established a Strategic Petroleum Reserve. It pursued negotiations with producers while also attempting to organize consumers. The International Energy Agency was founded in 1974 in response to the crisis. The IEA describes energy security as its founding mission, although its remit now includes a much wider energy system. IEA institutional history.
One side had built a forum for producers. The other developed a system for emergency coordination among consumers. IEA member countries have a stockholding obligation equivalent to at least ninety days of net oil imports and arrangements for a collective response to severe disruption. The obligation can be met through combinations of public emergency stocks and commercial stocks, including agreed holdings abroad. Net exporters do not face the same minimum-stock requirement. IEA stock rules.
Ninety days is not ninety days of a magically insulated economy. A stockpile is finite, it must contain the right material, and it must be released and moved through working infrastructure. But it changes the negotiating clock. An importer with a buffer can withstand a temporary interruption differently from an importer buying every next cargo with no cushion.
The lesson survives the original embargo. Energy security is not the elimination of dependence at any cost. It is the ability to keep essential systems operating when a supplier, route or price behaves badly. Diverse suppliers, emergency stocks, efficient machines and diplomatic relationships are different tools for the same vulnerability.
Consumers built institutions because individual companies could not solve a collective supply shock alone. Producers had built institutions for the opposite side of the bargain. Neither institution could abolish the geography between the two.
When the pump reaches the central bank
The Federal Reserve's historical account puts a number on the change: oil rose from $2.90 a barrel before the embargo to $11.65 in January 1974. It dates the US embargo to 19 October 1973, immediately after President Richard Nixon requested $2.2 billion in emergency aid for Israel. The embargo ended in March 1974; the higher price did not disappear with it. A temporary diplomatic restriction had helped establish a different economic baseline. Federal Reserve history.
There were two shocks inside the headline. One was a shortage of a physical input. The other was the redistribution of income caused by its new price. Importers had to send more purchasing power abroad for the same fuel. Exporters received more foreign currency. A factory buying diesel and a government buying military fuel could both experience a squeeze without consuming one additional barrel. That is why a fuel shock can become a balance-of-payments problem before anyone calls it a currency crisis.
The central bank then inherits a problem it cannot drill its way out of. If it tightens credit to contain inflation, it may deepen the slowdown. If it eases to protect activity, it may help the initial price shock spread through wages, borrowing and expectations. The Fed's history describes that trade-off and warns against treating oil as the sole explanation for the Great Inflation. Existing policy, demand and other supply pressures mattered. A barrel can start a difficult argument; it cannot explain every participant's decision.
A revolution, then a Saturday press conference
In January 1979, the Iranian Revolution had reduced the country's oil output by 4.8 million barrels a day, about 7% of world production at the time, according to the Fed's retrospective account. It also describes precautionary buying: fear of the next disruption encouraged customers to obtain oil before they actually needed it. Prices more than doubled between April 1979 and April 1980. Supply lost today and demand pulled forward from tomorrow worked in the same direction. The second oil shock.
A precautionary stock build has a strange collective effect. Each buyer seeks safety by buying earlier. Together, buyers can make the immediate market tighter. The producer sees urgent demand; the customer sees proof that urgency was justified. Inventories are useful buffers, but the act of creating them in a frightened market can first intensify the price pressure. A modern importer securing extra cargoes after a shipping attack faces the same basic timing problem, even when the politics are entirely different.
President Jimmy Carter appointed Paul Volcker as Federal Reserve chair in August 1979. On the evening of 6 October, after an unscheduled policy meeting, Volcker used a rare press conference to announce a shift towards controlling bank reserves rather than keeping the federal funds rate within its previous narrow range. The institutional scene matters: an oil shock had become an argument about the credibility of money. Volcker's announcement.
The Fed's account records farmers protesting at its headquarters and car dealers sending coffins containing keys from unsold cars. These were not oil traders. They were people whose businesses had encountered the interest-rate response to inflation. The chain had reached another destination: disrupted production, expensive energy, persistent inflation, tighter money, harder credit and unsold goods. The pain did not stay in the country where the well had stopped.
This is the historical bridge to the rupee and Indian equities later in the story. A company can be affected by oil directly through its fuel bill, indirectly through customer demand, and again through interest rates or the currency. Counting only the first channel understates the exposure. Attributing every price change to the same war overstates it. The useful work is to trace each channel separately, then see where they converge.
The next wars would attack that geography directly: production installations, ports, tankers and the thin lines joining them.
