Crude oil and commodity prices

In simple terms

Crude oil is one of the world's most important commodities, and India imports most of what it uses. So when oil prices rise, India pays more for imports, prices rise across the economy, and many companies' costs go up. When oil falls, the reverse happens.

Other commodities, such as metals, coal, gold, edible oils and fertiliser inputs, work in similar ways for the industries that use or produce them.

Oil and the economy

Inflation. Oil reaches consumer prices directly, through petrol, diesel and cooking gas, and indirectly, through transport costs and the many products made from petroleum, such as plastics, paints and chemicals. How quickly depends on how fuel prices are set and taxed, which governments change from time to time.

Trade and the rupee. A higher oil price raises the import bill, widening the current account deficit. India needs more dollars to pay for oil, which can weaken the rupee, as the currency movements lesson explains. Oil is priced in dollars, so a weaker rupee makes oil even more expensive in rupees.

Government finances. Taxes on fuel are an important source of revenue, and governments sometimes cut them, or support prices, when oil spikes, affecting the fiscal deficit.

Interest rates. If oil pushes inflation up, the RBI may keep rates higher, as the monetary policy lesson explains.

Winners and losers among companies

Producers benefit in the opposite way: if their costs per barrel are steady, a higher selling price flows mostly into profit. But governments sometimes change taxes or pricing rules on such gains, so the benefit is not guaranteed.

Pass-through and pricing power

Who bears a commodity cost increase depends on pass-through:

• Companies with strong brands or little competition can raise prices, protecting margins, as the competitive advantage lesson explains.
• Companies in competitive markets often absorb costs for a while, and margins shrink.
• Pass-through usually lags: margins dip when costs rise and recover when prices catch up, and may widen when costs fall before prices do.

That is why commodity-using companies' margins often move against commodity prices, with a delay.

Other commodities

• Metals, such as steel, aluminium and copper, matter for producers, as the commodity businesses lesson explains, and for users such as autos, construction and capital goods.
• Coal and gas affect power generation and heavy industry.
• Gold is a large import for India, affecting the trade balance and jewellery businesses.
• Edible oils and farm commodities affect food inflation and food processing companies.

Why it matters

Oil and other commodity prices change costs, margins, inflation and the rupee all at once. Knowing which companies use and which produce a commodity, and whether they can pass on costs, explains why the same price move can lift one share and sink another.

Limitations

Commodity prices are set in global markets by supply, demand, politics and weather, and are very hard to forecast. Effects on companies depend on contracts, inventories, hedging and pricing rules that change over time.

Common mistakes

• Assuming higher oil hurts every company equally.
• Ignoring the rupee when thinking about oil costs.
• Forgetting the delay in pass-through.
• Forecasting commodity prices instead of understanding exposures.

Try it yourself

1. Pick a company in an oil-using industry and find fuel or raw material costs as a share of revenue in its annual report.
2. Estimate how a 10% rise in that cost would change its operating profit if prices stayed the same.
3. Compare its operating margin with an oil price chart over several years and look for the delay.
