What Happened
- Oil prices surged past $115 per barrel by March 9, 2026, as the escalating US-Israel-Iran war disrupted global energy supply chains.
- Cornell University historian Nicholas Mulder described the 2026 shock as "the largest oil supply shock ever in economic terms," with three to four times as many barrels lost as during the 1973 and 1979 crises combined.
- Iran's closure of the Strait of Hormuz effectively blocked approximately one-fifth of global oil supply, while major OPEC producers in the region cut output further.
- Commentators drew historical parallels to the 1973 Arab Oil Embargo, the 1979 Iranian Revolution oil shock, the 1990 Gulf War, and the 2008 price spike — while also identifying key structural differences.
- The speed of the 2026 price surge — roughly 50% in under two weeks — exceeded the pace of the 1973 shock (which unfolded over several months).

The 1973 Oil Embargo — First Global Oil Shock
The 1973 oil crisis was triggered when Arab members of OPEC imposed an embargo during the Yom Kippur War (October 1973), targeting nations that had supported Israel, including the US, Western Europe, and Japan. It removed roughly 7-9% of global oil supply and caused prices to quadruple within months.
- Arab OPEC members: Saudi Arabia, Libya, Iraq, Kuwait, Qatar, UAE, Algeria, Bahrain, Egypt, and Syria — collectively imposed the embargo.
- Prices rose from approximately $3/barrel to $12/barrel by early 1974 (a 4x increase).
- The crisis led to the formation of the International Energy Agency (IEA) in 1974 under the OECD, to coordinate strategic oil reserves and energy security among consuming nations.
- The IEA requires members to hold Strategic Petroleum Reserves (SPR) covering 90 days of net imports.
- The crisis also spurred the development of oil fields outside OPEC (Alaska, North Sea, Mexico) to reduce western dependence.
Connection to this news: The 1973 embargo removed 7-9% of global supply; the 2026 Hormuz closure is estimated to block 20-25% of global seaborne oil trade, making it structurally far larger — though strategic reserves and US shale production provide buffers unavailable in 1973.
The 1979 Iranian Revolution and Second Oil Shock
The 1979 oil crisis followed the Iranian Revolution, which overthrew the Shah and established the Islamic Republic. Iranian oil production collapsed and the Iran-Iraq War (1980-88) further disrupted regional supply, together cutting global output by several million barrels per day and pushing prices above $35/barrel.
- Iran was the world's second-largest oil exporter before 1979; its output fell from ~6 million bpd to under 2 million bpd during the revolution.
- The Islamic Republic, established in 1979 under Ayatollah Ruhollah Khomeini, introduced the concept of Velayat-e-Faqih (Guardianship of the Islamic Jurist) as the governing principle — relevant context for understanding the current leadership crisis after Ali Khamenei's death.
- The Iran-Iraq War (1980-88) was partly enabled by the post-revolution power vacuum and was backed by different external powers — the US supported Iraq, while Iran received covert arms through the Iran-Contra affair.
- The crisis led to the Carter Doctrine (1980): the US declared it would use military force to defend its interests in the Persian Gulf.
Connection to this news: The 2026 war strikes the same geography as the 1979 crisis, but with Iran now far more integrated into global oil markets and the Strait of Hormuz closure affecting a larger share of global supply than the 1979 supply reduction did.
India's Historical Oil Vulnerability and Strategic Petroleum Reserves
India has no history of domestic oil self-sufficiency — unlike the US, which emerged as a major shale producer after 2010. Each global oil shock has hit India hard, given its structural import dependence. In response to vulnerability, India has developed Strategic Petroleum Reserves (SPR).
- India's SPR capacity: approximately 5.33 million tonnes across three underground caverns — Visakhapatnam (Andhra Pradesh), Mangaluru (Karnataka), and Padur (Karnataka) — managed by the Indian Strategic Petroleum Reserves Limited (ISPRL) under the Ministry of Petroleum.
- India's SPR covers approximately 9-10 days of crude import requirements — far below the IEA's 90-day standard (India is not an IEA member).
- India became a Strategic Partner of the IEA in 2017 and an Association Country in 2024, which improved energy data sharing but does not grant full SPR obligation benefits.
- India also holds commercial stocks at refineries (typically 30-45 days).
- The 1973 and 1979 shocks had no SPR buffer for India; the 2026 shock is partly cushioned by these reserves.
Connection to this news: India's SPR provides only a short-term cushion (9-10 days), insufficient for a prolonged Hormuz closure. The historical pattern — crisis → reserve build-up — may accelerate India's plans to expand SPR capacity.
Key Facts & Data
- 1973 shock: oil prices quadrupled; ~7-9% of global supply removed; triggered IEA formation (1974).
- 1979 shock: prices rose to $35+/barrel; Iran production fell from ~6 million bpd to under 2 million bpd.
- 2026 shock: prices rose ~50% in under two weeks; Strait of Hormuz closure threatens ~20-25% of global seaborne oil.
- Nicholas Mulder (Cornell): "Roughly 3-4x as many barrels lost as during 1973 and 1979 crises."
- India's SPR: 5.33 million tonnes across Visakhapatnam, Mangaluru, Padur — covers ~9-10 days of imports.
- India became IEA Strategic Partner in 2017 and Association Country in 2024.
- US oil production (2025): ~18.9% of global supply (up from 15.6% in 1973) — provides a larger buffer now than in past crises.
- IEA was established in 1974 under the OECD following the 1973 crisis; HQ in Paris.
