Yom Kippur War & OPEC Oil Embargo — October 1973
The first oil shock and the 1973-74 bear market
OPEC imposed an oil embargo on October 19, 1973 in retaliation for U.S. support of Israel during the Yom Kippur War. Oil quadrupled from roughly $3 to $12 per barrel. The S&P 500 fell 48% from its January 1973 high of 121.74 to its October 1974 low of 62.28, triggering stagflation with inflation above 12%.
What history says
Editorial commentary written by ALAN analysts. Figures cited below are analyst-authored context — they are not derived from the chart above and may reflect different windows or sources.
The S&P 500 did not crash immediately — it ground lower for 21 months, eventually halving from peak to trough. The slow bleed was worse than a sharp crash because investors had no clear capitulation moment.
The 300% rise in oil prices fed directly into transportation, manufacturing, and food costs. GDP contracted 0.5% in 1974 while inflation ran above 12% — stagflation that made the Fed's job nearly impossible.
The S&P 500 nominally recovered by mid-1976, but adjusted for inflation the index did not return to its 1973 peak until the early 1980s.
This is the counterexample worth respecting: when an oil shock embeds into broad inflation, the damage runs through rates and real returns for years, not weeks. Consider whether your portfolio carries inflation-resilient assets — 1973-74 punished allocations built on the assumption that every geopolitical shock mean-reverts quickly.
