In October 1973, long lines at American gas stations stretched for miles, drivers waiting hours to fill a tank—this is the collective memory left by the first oil crisis. Fifty years later, when traffic through the Strait of Hormuz dropped from 130 vessels daily to just 6, and oil prices surged 60% in a week, history seems to be repeating itself in an astonishing way.
But this time, is the script really the same?
I. The 1970s: How Two Crises Reshaped the World
First Oil Crisis (1973-1974): OPEC's Awakening
On October 6, 1973, the Yom Kippur War broke out. Arab oil-producing countries used oil as a weapon, imposing embargoes on Western countries supporting Israel. In just three months, international oil prices soared from $3 per barrel to $12, an increase of over 300%.
The impact of this crisis was systemic:
More importantly, it permanently changed the global power structure. OPEC transformed from a loose pricing coordination organization into a geopolitical force capable of determining the world's economic lifeline.
Second Oil Crisis (1979-1981): Chain Reaction of the Iranian Revolution
In 1979, the Islamic Revolution in Iran overthrow the Pahlavi dynasty. The world's second-largest oil exporter's production plummeted 88% from 6.09 million barrels/day to 730,000 barrels/day. Oil prices climbed from $15 per barrel to $39 by 1981, nearly doubling.
This time, the Federal Reserve's response became a historical turning point. Chairman Paul Volcker pushed the federal funds rate above 20% to violently raise interest rates and curb inflation. The cost was painful—the US economy陷入 deep recession from 1980-1982, with unemployment once exceeding 10%.
But Volcker's iron fist ultimately tamed inflation and laid the foundation for the later "Great Moderation" era.
Historical Pattern Summary
Looking back at the two crises, three patterns emerge:
1. **Trigger Mechanism**: Crises are often triggered by sudden geopolitical events (wars, revolutions), not pure market supply-demand imbalances
2. **Duration**: From oil price surge to crisis resolution typically takes 2-3 years
3. **Resolution Path**: Either through diplomatic negotiations to restore supply (post-1973), or through alternative energy and efficiency improvements to reduce dependency (post-1980s)
II. Strait of Hormuz: The 21st Century's Energy Chokepoint
Strategic Value: 20% of Global Oil Flows Here
The Strait of Hormuz is only 48 kilometers at its narrowest point, yet it's the "chokepoint" for global energy transportation. About 20 million barrels of crude oil pass through here daily, accounting for one-third of global seaborne oil trade and one-fifth of total global oil consumption.
Data from March 2025 shows vessel traffic through the strait dropped from an average of 130 per day in February to just 6, a decline of about 95%. Multiple international insurers have cancelled war risk insurance for the region, further inhibiting ship traffic.
Current Pattern: Iran-West Escalation
Iran's ability to control the Strait of Hormuz stems from its geography—the north shore of the strait is completely under its control. In recent years, Iran has repeatedly used blocking the strait as leverage against Western sanctions:
Red Sea Crisis Chain Reaction
Since late 2023, Houthi forces have been continuously attacking ships "linked to Israel" in Red Sea waters under the pretext of supporting Palestine. The Bab al-Mandab Strait, as the chokepoint connecting the Red Sea and Indian Ocean, forms a strategic呼应 with the Strait of Hormuz.
This叠加 effect of the "dual strait" crisis has put unprecedented pressure on global energy supply chains.
III. New vs Old Crisis: What Changed and What Didn't
What Changed?
1. **Energy Structure: US from Importer to Exporter**
In the 1970s, the US was the world's largest oil importer, with 35% dependency on Middle Eastern oil. The shale revolution changed everything—by 2024, the US became the world's largest oil producer, with daily production exceeding 13 million barrels, and achieved net energy exports.
This transformation means: the US is no longer as vulnerable as in the 1970s, but global oil market supply patterns have also been reshaped.
2. **Strategic Reserves: From Reactive to Proactive**
In the 1970s, Western countries had virtually no strategic oil reserves. Today, International Energy Agency (IEA) member countries' total strategic reserves exceed 4 billion barrels, equivalent to 90 days of global consumption. The US Strategic Petroleum Reserve (SPR) peaked at 727 million barrels.
3. **New Energy Rise: More Alternatives to Oil**
In the 1970s, oil accounted for nearly 50% of global energy consumption with almost no alternatives. By 2024, renewables account for 30% of global electricity generation, and EV penetration has exceeded 20% in some countries. Oil's "irreplaceability" is weakening.
What Didn't Change?
1. **Unpredictability of Geopolitical Conflict**
Whether the 1973 Yom Kippur War or the 2025 Iran-Israel conflict, the suddenness and unpredictability of geopolitics remains the biggest variable in oil price fluctuations.
2. **Market Panic Amplification Effect**
During crises, oil price increases often far exceed the actual scale of supply-demand gaps. In 1973, oil prices rose 300% but global supply shortfall was only about 5%; in 2025, oil prices rose 60% in a week but the Strait of Hormuz wasn't completely closed. Panic amplifies price volatility.
3. **Inflation vs Monetary Policy Dilemma**
In the 1970s, central banks struggled between "controlling inflation" and "maintaining growth." Today, the Fed faces the same dilemma: raising rates suppresses the economy, not raising rates means runaway inflation.
IV. Impact on China: Real Test of Energy Security
High Dependency Structural Vulnerability
In 2024, China's crude oil import dependency reached 72.2%, with daily imports exceeding 11 million barrels—this scale even exceeds the daily production of Saudi Arabia, the world's largest oil producer. About half comes from the Middle East, with a significant portion requiring transport through the Strait of Hormuz.
This means: any interruption at the Strait of Hormuz will directly impact China's energy security.
China's Response: Strategic Reserves and Diversification
In recent years, China has been accelerating its布局:
But these measures take time. In the short term, China's high dependency on Middle Eastern oil is difficult to fundamentally change.
Economic Impact Assessment
If Strait of Hormuz blockage keeps oil prices sustainably above $100/barrel:
V. Investment Implications: Finding Certainty in Uncertainty
History doesn't repeat itself, but it often rhymes. Facing the new round of energy geopolitics, investors can position across several dimensions:
1. **Traditional Energy Sector: High Oil Price Beneficiaries**
If Hormuz crisis persists, higher oil price center directly benefits oil exploration companies. Focus on low-cost advantage, high production flexibility oil & gas companies, and oil ETFs (like USO, XLE).
2. **Energy Transport & Defense: Geopolitical Risk Premium**
Tanker rates often surge significantly during geopolitical tensions, creating trading opportunities in shipping sector. Meanwhile, defense/military sector typically performs strongly during geopolitical escalation.
3. **New Energy: Strengthening Long-term Logic**
Every energy crisis accelerates alternative energy development. The 1970s oil crisis spawned nuclear, natural gas, and energy conservation technologies; today's crisis will further drive solar, wind, storage, and EV adoption.
4. **Gold & Safe-haven Assets: Hedging Tail Risk**
In highly uncertain geopolitical environments, gold's value as a safe-haven asset stands out. Meanwhile, the dollar typically strengthens during energy crises, giving dollar assets defensive properties.
Conclusion: New Game in the Cycle
The 1973 oil crisis ended the post-war golden growth period and opened the stagflation era; will the 2025 Hormuz game repeat history?
The answer may lie in: this time, the world is more prepared—strategic reserves, shale oil, new energy. But the unpredictability of geopolitical conflict and the fragility of global supply chains remain the Sword of Damocles hanging overhead.
For Chinese investors, energy security is not just a macro topic, but a real consideration in asset allocation. Finding certainty in uncertainty may be the only path through the cycle.
