Discuss the multi-dimensional implications of uneven distribution of mineral oil in the world.

Approach · directive: “discuss”

What it asks · Explain the political, economic, strategic, social and environmental consequences of oil being concentrated in a few regions while demand is spread across the world.

It asks 5 things — answer each

  1. Discuss: where oil is concentrated and where demand lies
  2. Discuss: the geopolitical and strategic implications
  3. Discuss: the economic implications for importers and exporters
  4. Discuss: the social, political and environmental implications
  5. Discuss: how importers such as India respond

Open with · Oil follows geology, not demand: it collects in old sedimentary basins such as the Persian Gulf, while the largest consumers lie elsewhere; OPEC members hold 1,241 of the world's 1,567 billion barrels of proven reserves (end-2024).

Cover

  • Unevenness: OPEC holds about four-fifths of proven reserves; India, China, Japan and Europe depend on imports.
  • Geopolitical: chokepoints such as Hormuz, cartel quotas, wars and sanctions make oil a tool of power.
  • Economic: India imports over 85% of its crude, so price spikes feed inflation and the current account deficit.
  • Exporters: rent dependence, Dutch disease and exposure to price crashes.
  • Social-political: rentier states, Gulf labour migration and remittances, inequality in producing regions.
  • Environmental: Deepwater Horizon (2010) spill, deep-sea and Arctic frontiers, carbon lock-in.
  • India's response: 5.33 MMT strategic reserves, gas, ethanol, compressed biogas and EV charging.

Close with · Geology cannot be redistributed, so energy security lies in diversifying fuels; SDG 7 (affordable and clean energy) turns oil's unevenness into a reason for transition.

Oil follows geology, not demand: it collects in old sedimentary basins such as the Persian Gulf, while the largest consumers lie elsewhere. Since then, OPEC's end-2024 count puts OPEC members at 1,241 of the world's 1,567 billion barrels of proven reserves, so a few regions shape everyone's energy security.

Geopolitical and strategic implications

  • Chokepoints: Gulf crude passes the Strait of Hormuz and Malacca, so sea-lane security and naval reach become oil policy.
  • Cartel power: OPEC and allied producers set output quotas, moving prices and shifting wealth between regions.
  • Conflict and coercion: oil-rich West Asia has drawn repeated wars, foreign intervention and sanctions; energy supply becomes a weapon.

Economic implications

  • Importers exposed: India imports more than 85% of its crude; the Indian basket rose from $55/bbl (March 2015) to $116/bbl (June 2022, since then), feeding inflation and the current account deficit.
  • Resource curse: exporters lean on oil rents, so price crashes hit budgets, and Dutch disease (a strong currency) hurts other exports.

Social, political and environmental implications

  • Rentier states: oil revenue funds subsidies without taxing citizens, weakening accountability and often sustaining authoritarian rule.
  • Labour migration: Gulf economies draw large numbers of migrant workers, including Indians, whose remittances support families at home.
  • Local inequality: producing regions often bear displacement and pollution while revenue flows to distant elites.
  • Frontier spills: the Deepwater Horizon blowout of 20 April 2010 in the Gulf of Mexico shows the cost of drilling ever deeper seas.
  • Carbon lock-in: cheap oil sustains transport emissions and delays climate goals.

Way forward: how importers like India respond

  • Buffer stocks: ISPRL's 5.33 MMT strategic reserves at Visakhapatnam, Mangaluru and Padur, for use during supply shocks.
  • Demand substitution: natural gas, ethanol blending, compressed biogas, biodiesel and electric-vehicle charging infrastructure.
  • Diversified sourcing: a wider supplier basket and overseas equity oil reduce dependence on any one region.

Geology cannot be redistributed, so energy security now lies in diversifying fuels; SDG 7 (affordable and clean energy) turns oil's unevenness from a strategic weakness into a reason for transition.
