The ongoing war in the Middle East has driven crude oil prices to record highs, with some benchmarks surpassing $100 per barrel this week. But while motorists feel the immediate sting at fuel pumps, the true reach of crude oil extends into nearly every corner of modern life, from the fertiliser that grows food to the plastic in mobile phones.
When refineries process crude oil, they create far more than just petrol and diesel. The complex hydrocarbon is transformed into thousands of products that form the backbone of contemporary society, making supply disruptions particularly far-reaching.
The most visible products are transportation fuels. Petrol powers cars, diesel runs lorries and farm equipment, and jet fuel keeps aircraft aloft. These account for the largest share of refined oil products. But the refining process also yields heavier fractions used to produce asphalt for roads, lubricating oils for machinery, and paraffin wax.
Less visible but equally critical are petrochemicals, the building blocks for plastics, fertilisers, pharmaceuticals, and synthetic materials. Major petrochemicals including ethylene, propylene, and benzene serve as intermediate materials that manufacturers transform into finished goods.
The plastics industry relies heavily on these petroleum derivatives. Everything from food packaging and toys to electronics components and medical equipment contains oil-based plastics. Mobile phones, laptops, and household appliances all incorporate materials derived from crude oil.
In agriculture, petroleum plays a dual role. Beyond fuelling tractors and transport, it provides the raw materials for nitrogen-based fertilisers including urea ammonium nitrate, which farmers depend on to boost crop yields.
The pharmaceutical industry also draws on petroleum derivatives to manufacture medicines including aspirin and antihistamines. Cosmetics, detergents, paints, and synthetic fibres for clothing all trace their origins to crude oil.
Even the tyres on vehicles contain synthetic rubber made from petrochemicals, whilst construction materials including sealants and insulation often incorporate petroleum-based compounds.
The International Energy Agency projects that demand for petrochemicals will continue growing, driven particularly by increasing needs for plastics and fertilisers in developing economies.

This extensive dependence explains why the current crisis carries such broad implications. The war has caused the largest oil supply disruption in history, according to the IEA, with global supply expected to drop by eight million barrels per day. The blockade of the Strait of Hormuz, which normally carries 20% of the world’s oil and liquefied natural gas, has forced prices sharply higher.

Consumers now face not only rising fuel costs but also potential increases across a vast array of manufactured goods. The disruption threatens global food security as fertiliser and agricultural fuel costs climb, while manufacturing costs for countless products edge upward.
The crisis has exposed modern society’s profound reliance on a single commodity. From the morning commute to the food on dinner tables, from life-saving medicines to everyday conveniences, crude oil remains woven into the fabric of contemporary life.

As prices remain elevated and supply constraints persist, the cascading effects of this dependence are becoming increasingly apparent to consumers worldwide.
