An Economy Under the Pump

The answer to this question lies thousands of kilometres away, in a region many of us may have never visited: the Middle East, where tensions involving the United States of America have escalated into conflict. While this may seem distant and unrelated, such events can directly influence everyday life in other countries, including Australia.

Geopolitics - how countries interact with each other based on power, resources and location - causes this conflict to impact everyone around the world. Consider it like a network: some countries control very vital resources, like oil, and others depend on those resources to run their economies. When mega powers such as the U.S. become involved in conflict with resource-rich regions, it can gravely disrupt the global flow of goods.

This crisis doesn’t just affect the price of filling up our cars. Oil and petroleum products supply an entire transportation system (cars, trucks, planes), electricity generation (in some regions), and the manufacturing of plastics, chemicals, agricultural purposes (fertilizers, machinery). This is why, when fuel becomes expensive, almost everything else becomes expensive too.

Most of the world’s oil passes through a narrow route called the Strait of Hormuz. The Strait of Hormuz is a narrow maritime passage connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. It is one of the world’s most important strategic chokepoints, carrying roughly one-fifth of global oil trade and about one-third of global liquefied natural gas exports, not to mention other key resources such as fertilizer. The stability of the Strait of Hormuz directly influences global energy prices and geopolitical security.

This is why, when conflict escalates in this region, ships may be delayed or blocked, oil supply becomes uncertain and the markets panic. According to Reuters (2026), this uncertainty has pushed global oil prices above $100 per barrel. With the simple logic of less supply and more demand creating a shortage, the prices go up.

One of the most important economic characteristics of fuel is that its demand is relatively price inelastic, which means that even when prices rise significantly, consumption does not fall proportionately. Households still need transport, businesses still require logistics, and farmers still rely on fuel for production. Historical data reinforces this: during the 1979 oil crisis, U.S. oil consumption declined by only around 8% despite substantial price increases. Over time, demand rebounded as economic activity adjusted. This demonstrates that fuel is not a luxury good; rather, it is a necessity. As a result, price increases tend to translate directly into higher costs rather than reduced consumption.

The oil market itself is shaped less by monopolistic competitors and more by strategic control among key players. The Organization of the Petroleum Exporting Countries (OPEC), an oligopoly largely composed of Middle Eastern nations, holds significant influence over global supply. Within this group, Saudi Arabia acts as a “swing producer,” adjusting output to stabilise or influence prices.

However, this dominance has been challenged by the rise of U.S. shale oil production, which has increased global supply and reduced OPEC’s monopoly-like control. Despite this, the market remains concentrated, making it highly sensitive to geopolitical developments.

FLOW-ON EFFECTS

A supply-side domino effect occurs when fuel prices rise and the economy experiences cost-push inflation, a chain reaction that spreads across sectors. For instance, higher fuel prices increase transportation costs; consequently, logistics and delivery become more expensive, businesses face rising production costs, firms pass these costs onto consumers, and workers demand higher wages to maintain living standards. This creates an inflationary feedback loop.

Historical precedent shows how dire this can become - during the late 1970s, extreme inflation (driven partly by oil shocks) led the U.S. Federal Reserve, under Paul Volcker, to sharply raise interest rates to restore economic stability.

Moreover, oil shocks can lead to stagflation from inflation, which is a combination of high inflation and slow economic growth. As production costs rise, businesses reduce output. At the same time, higher prices reduce consumer spending. The economy slows, but inflation persists.

From a demand perspective, oil inflation reduces purchasing power of money. Households spend more on essentials such as fuel and food, leaving less for discretionary spending. This often leads to reduced overall consumption. Consumers and firms may gradually transition towards less energy-intensive activities, but these adjustments take time, making short-term economic pressure unavoidable.

To add to that, this rise to inflation due to oil has significant implications for international trade and exchange rates. Countries that import large amounts of oil, such as Australia, must spend more money abroad when prices rise. This worsens the trade balance and can weaken the national currency. Australia is particularly vulnerable. According to Reuters (2026), the country imports around 90% of its refined fuel, meaning global price increases are quickly transmitted domestically. A weaker currency further increases import costs, reinforcing inflationary pressures across the economy.

The impacts of oil inflation are being felt deeply in Australia. As noted by reports in The Guardian (2026), oil inflation means that higher costs for fuel and supplies contribute to the rising cost of food, even down to simple things like fish and chips. Oil inflation demonstrates the reality that exists when we consider the impact of our global economy; it is an interconnected economy, one that is highly dependent on fuel through every stage of the supply chain.
