Oil prices: on the up

Saturday 7 March 2026

The global price of oil has once again become a barometer of geopolitical tension. The escalation of war in the Middle East has pushed Brent crude above $90 per barrel, with some analysts warning that prolonged disruption could drive prices to $120 or even $150 if the conflict interferes with shipping through the Strait of Hormuz or reduces production across the Gulf. 

Such movements remind us that the economics of oil are inseparable from the politics of the regions in which it is produced. Oil is not simply another commodity traded on global markets; it is the bloodstream of the modern industrial economy. Consequently the price of oil reacts not only to actual shortages but also to fear, expectation and the perception of strategic vulnerability. Understanding the recent price movements requires examining the fundamental economics of oil supply and demand, the strategic structure of the global petroleum industry and the particular vulnerabilities of Middle Eastern production.

The structural economics of oil markets

Oil markets are characterised by an unusual economic property: both supply and demand are highly inelastic in the short term. Consumers cannot easily reduce their use of oil when prices rise, because transport, agriculture and industry depend upon petroleum products that cannot be quickly substituted. Similarly, producers cannot instantly increase output, because oil extraction requires complex infrastructure, long investment cycles and physical reservoirs that cannot be rapidly expanded. 

The result is that small disruptions in supply can produce disproportionately large movements in price. When traders believe that a few million barrels per day may be removed from global circulation, the price of the entire market can move dramatically, because the remaining supply cannot easily adjust to compensate. Oil markets therefore behave more like systems of strategic scarcity than conventional competitive markets.

This structural fragility explains why geopolitical risk commands such influence over petroleum pricing. Traders price not only the oil currently being produced but also the probability that supply may be interrupted tomorrow.

The geopolitical risk premium

The notion of a “risk premium” is central to understanding oil pricing during wartime. Even if the physical flow of oil continues uninterrupted, markets may still react to the possibility that supply could be disrupted.

In the current Middle Eastern conflict, the principal anxiety concerns the Strait of Hormuz, the narrow maritime passage through which roughly a fifth of global oil exports travel. Any military activity that threatens tanker traffic in this region immediately raises fears of a systemic supply shock.

The recent surge in prices reflects precisely this mechanism. Oil benchmarks have jumped sharply following strikes and counter-strikes involving Iran and Western powers, with traders fearing disruptions to Gulf production and shipping routes. 

Importantly, such price reactions occur before any actual shortage emerges. Oil markets respond to expectations rather than events alone.

Spare capacity and the stabilising role of OPEC

Historically the Organisation of the Petroleum Exporting Countries has functioned as a stabilising mechanism in global oil markets. Several of its member states—most importantly Saudi Arabia—maintain “spare capacity”: oil production that can be rapidly activated when supply elsewhere is disrupted.

This spare capacity acts as a shock absorber. When geopolitical crises remove oil from the market, OPEC producers can increase output to prevent prices from spiralling upward. 

Yet the effectiveness of this system depends upon the amount of spare capacity available. If global production is already operating close to maximum levels, the ability of OPEC to stabilise markets diminishes and price volatility increases dramatically. 

The present crisis is particularly sensitive because global spare capacity has been gradually eroding in recent years as production cuts are reversed and demand continues to grow. In such circumstances the oil market becomes acutely vulnerable to geopolitical shocks.

A paradox of abundance and scarcity

There is an important paradox in contemporary oil economics. Over the long term, global oil supply has expanded significantly due to the rise of American shale production and new offshore fields. These developments have reduced the structural dependence of oil markets on the Middle East compared with the late twentieth century.

Indeed analysts have noted that the historical relationship between Middle Eastern conflicts and oil prices has weakened in recent years, because global supply is now more diversified. 

However diversification does not eliminate vulnerability. Oil remains globally traded and transport networks remain concentrated through a small number of maritime chokepoints. Even if the world possesses sufficient oil in aggregate, the interruption of major shipping routes can create severe short-term dislocations.

In this sense, the oil market is not merely a question of geology but of logistics.

Macroeconomic consequences of rising oil prices

When oil prices rise sharply, the effects propagate rapidly through the global economy. Oil is embedded in nearly every production process: transportation, manufacturing, agriculture and electricity generation all depend upon it.

Consequently rising oil prices function as a tax on economic activity. Higher fuel costs increase transportation expenses, raise food prices and push inflation upward. Economists estimate that sustained oil price increases can significantly reduce economic growth while raising consumer prices simultaneously. 

The inflationary consequences are particularly acute in energy-importing regions such as Europe. Countries that rely heavily upon imported energy experience immediate pressure on their trade balances and domestic prices when oil becomes more expensive.

In contrast, oil-exporting states often experience windfall revenues during price spikes. For countries such as Russia, Saudi Arabia or the Gulf monarchies, rising oil prices translate into increased fiscal resources and stronger geopolitical leverage.

The financialisation of oil markets

Another defining feature of contemporary oil economics is the role of financial markets. Oil is traded not only as a physical commodity but also as a financial asset through futures contracts and derivatives.

This transformation of oil pricing into the derivative markets means that investment funds, banks and hedge funds play a substantial role in determining short-term price movements. Traders react rapidly to geopolitical news, adjusting their positions in anticipation of future disruptions.

As a result oil prices can sometimes move more dramatically than underlying physical supply conditions might justify. Markets are pricing risk, not merely barrels.

The strategic dimension

Oil therefore occupies a unique position at the intersection of economics and strategy. Control over production capacity, shipping routes and energy infrastructure has profound geopolitical consequences.

For this reason conflicts in the Middle East have historically exerted outsized influence over the global economy. Wars in the Gulf region are not merely regional events; they reverberate through financial markets, inflation rates and national budgets across the world.

The present crisis illustrates this dynamic vividly. Even before the physical consequences of the conflict are fully known, oil markets have reacted strongly, reflecting the strategic importance of the region’s energy infrastructure.

Conclusion

The economics of oil prices cannot be understood solely through the conventional language of supply and demand. Oil markets are shaped by a unique combination of structural inelasticity, geopolitical risk and financial speculation.

In periods of stability these forces remain largely invisible. But when war erupts in regions central to global energy supply, they become suddenly apparent.

The current Middle Eastern conflict has once again demonstrated how fragile the equilibrium of the global oil market can be. A few missiles, a threatened shipping lane or a disrupted refinery can move prices across the entire world economy.

Hence oil remains what it has always been since the twentieth century began: not merely a commodity, but a strategic resource whose price reflects the anxieties of the international system itself.
