Oil is so valuable because it is still the backbone of global energy and a core ingredient in thousands of everyday products, which makes modern economies heavily dependent on it. Its mix of high energy density, ease of transport, and deep integration into industry and trade keeps demand strong, so small supply shocks or geopolitical risks can push prices and perceived value up quickly.

What oil actually does

  • Oil supplies a large share of the world’s total energy use, especially for transport fuels like gasoline, diesel, and jet fuel.
  • In many countries, oil still meets the overwhelming majority of transportation demand (for example, over 90% in some advanced economies), tying mobility and logistics directly to oil markets.
  • Because energy is an input into almost every good and service, changes in oil prices ripple through overall living costs and inflation.

Beyond fuel: hidden in everyday stuff

  • Oil is the starting point for most modern plastics, which show up in phones, cars, packaging, furniture, and nearly all consumer electronics.
  • Petrochemicals derived from crude oil are used to make fertilizers, detergents, paints, synthetic fibers, and even some pharmaceuticals and medical equipment.
  • This chemical versatility means replacing oil would require not just a new fuel, but an overhaul of entire materials and manufacturing systems.

Economic and geopolitical power

  • Oil is one of the most traded commodities on Earth, so exporting countries can earn huge revenues that shape their budgets, currencies, and political influence.
  • Because many strategic sectors (aviation, shipping, trucking, military logistics) still rely on oil, stable access to it is treated as a national security priority.
  • Shocks to supply, such as wars, sanctions, or major refinery outages, can send prices sharply higher, reinforcing the perception that oil is “strategic” and highly valuable.

Why it has been so cheap (and why that matters)

  • Historically, conventional oil was abundant and relatively easy to extract, making it cheaper than most practical alternatives for decades.
  • Cheap oil enabled mass car ownership, globalized supply chains, and low-cost consumer goods, so societies built infrastructure and lifestyles around it.
  • As easy reserves deplete and some producers turn to deepwater, shale, or oil sands, production costs and environmental risks rise, adding to long‑term value but also to volatility.

The climate and transition angle

  • Burning oil releases carbon dioxide and other pollutants, making it a major driver of climate change and local air quality problems.
  • Despite rapid growth in renewables and electric vehicles, global systems for transport, petrochemicals, and heavy industry are still built around oil, so demand remains high in the 2020s.
  • The tension between climate goals and economic dependence on oil is part of what keeps oil a central, closely watched, and often controversial resource.
