The price of oil is once again setting the tone of the world economy
After a period in which investors and central banks were primarily concerned with interest rates, industrial slowdown and disruptions in trade, oil returned in March 2026 to the centre of the global economic story. The new rise in crude oil prices has once again raised the question of how resilient large economies really are to energy shocks and how quickly more expensive energy can change expectations about inflation, growth and the cost of living. Markets are no longer observing only the price per barrel itself, but also the duration of the disruption, the geographic scope of risk and the possibility that a temporary spike could turn into a longer period of more expensive energy products. That is precisely why oil is no longer just a commodity important for the energy sector, but a signal that affects bonds, currencies, stocks, transport costs, industrial business plans and everyday household budgets.
According to the latest estimates by the U.S. Energy Information Administration, Brent reached 94 dollars per barrel on March 9, about 50 percent more than at the beginning of the year and the highest since September 2023. That jump is linked to military activity in the Middle East, reduced passage of oil shipments through the Strait of Hormuz and the shutdown of part of regional production. For the world economy, the very fact that the energy market has once again begun to build a geopolitical risk premium into prices is already important. When oil becomes more expensive so quickly, the effect is not limited to refineries and energy traders, but almost automatically spills over into fuel prices, logistics, air and road transport, agriculture, the chemical industry and all sectors that depend on transport and energy inputs.
Why this rise in prices is more important than the number on the screen itself
In every major energy disruption, it is crucial to distinguish a short-lived market jolt from a shock that changes the behaviour of companies and consumers. If prices quickly return to previous levels, the economy usually suffers a limited blow. But if high prices remain, companies begin to build more expensive energy into their price lists, carriers raise tariffs, manufacturers seek new margins, and households cut other spending to cover higher fuel and heating bills. That is precisely the reason why in March the discussion is no longer only about one strong jump in the price of oil, but about whether the disruption will last long enough to become a first-rank macroeconomic problem.
The International Monetary Fund warned in recent days that this is a risk that can become much broader than the energy sector. According to the Fund’s estimate, every 10 percent increase in the price of oil that persists through most of the year can raise global headline inflation by about 0.4 percentage points and reduce global output by 0.1 to 0.2 percent. This estimate is important because it shows that oil acts in two ways: first through the direct rise in energy and fuel prices, and then through weaker growth, more expensive business operations and weaker purchasing power of the population. In other words, the market is afraid not only of inflation, but also of a scenario in which more expensive energy arrives at the same time as a slowdown in economic activity.
Such a scenario is especially sensitive for countries that are large importers of energy. European economies, although after earlier energy crises they strengthened diversification of supply and savings, still remain vulnerable to a sudden rise in oil and gas prices. When energy becomes more expensive, European industry loses part of its cost competitiveness, and households feel the pressure through fuel, transport and a range of products whose price depends on logistics. In such circumstances, even states that are not formally faced with a shortage of energy products can feel a very real blow through a more expensive life and more cautious investment.
The Strait of Hormuz again as a strategic point of world trade
The central place of today’s shock is not only production itself, but also the transport route. The Strait of Hormuz remains one of the most important energy arteries in the world, because a large part of global oil trade passes through it. When danger to tanker traffic increases in that area, the market reacts even before production statistics fully change. The risk premium enters the price almost instantly because market participants are not insuring themselves only against what has happened, but against what could happen in the coming days or weeks.
That is precisely the reason why stock exchanges and analysts this time are not looking only at how many barrels are currently lost, but at how long reduced delivery throughput could last. If the slowing of passage through Hormuz persists, insurance, transport and procurement costs will rise even before the physical shortage fully becomes visible in storage facilities. This additionally intensifies volatility, because the market reacts to an expected shortage, and not only to a confirmed deficit. In practice, this means that even the threat of a longer disruption can be enough to keep prices elevated.
The Associated Press reported this week that war and security risks related to Iran, the United States and Israel have led to strong price fluctuations, with Brent briefly close to 120 dollars per barrel before falling below that level. Although such intraday and multi-day changes are typical of periods of heightened risk, more important than the peak itself remains the question of whether the market will return to a more stable range or remain at noticeably higher levels than at the beginning of the year. It is precisely in this uncertainty that the greatest burden for the economy arises, because companies and consumers do not make decisions on the basis of the optimistic scenario, but on the basis of the more expensive and less favourable range that they consider possible.
Inflation may no longer be only a story about food and services
The rise in oil prices is coming at a time when many developed economies expected a gradual calming of inflation. In the euro area, according to Eurostat’s flash estimate, annual inflation reached 1.9 percent in February, after 1.7 percent in January. At the same time, the data showed that the energy component was still negative year-on-year in January, while services remained the main source of inflationary pressure. This means that Europe entered the energy shock at a moment when energy was no longer the main driver of consumer price growth, but with the new rise in oil it could become so again.
For central banks, this is a particularly awkward moment. If inflation is falling thanks to the easing of earlier shocks, monetary authorities can think about a looser policy. But if energy returns as an important source of price increases, a dilemma opens up as to whether interest rates should be used to react to a shock that is beyond the reach of monetary policy or whether they should instead “look through” a one-off jump in prices. The problem arises when the market begins to suspect that the shock is not one-off. Then the danger of so-called second-round effects increases: more expensive energy passes through to food, transport, services and the expectations of workers and companies, and inflation proves more stubborn than central banks had planned.
The U.S. Federal Reserve and the European Central Bank have for months warned that the energy channel is one of the reasons why it is too early to declare final victory over inflation. In periods of elevated oil prices, central banks must distinguish a short-lived jump in fuel prices from a broader change in the inflation regime. For citizens, however, the difference is often less important: as soon as fuel and transport become more expensive, the feeling that life is more expensive grows, regardless of how the structure of the consumer price index is technically interpreted. That is precisely why energy also has a strong political effect, because it enters the everyday experience of voters very quickly.
What the latest projections say about the oil market
Interestingly, the medium-term picture of the market is still not unambiguous. As early as the end of October 2025, the World Bank estimated that 2026 could, because of weaker growth and rising supply, bring a decline in commodity prices, including energy products, and the lowest levels of global raw material prices in six years. In recent months, the International Energy Agency has also warned of growing supply surpluses and the strong contribution of producers outside the OPEC+ group, especially from the United States, Brazil, Canada, Guyana and Argentina. From that perspective, 2026 was supposed to be a year in which more abundant supply would limit price growth.
But that is precisely why the current spike is important: it shows how quickly geopolitical risk can overpower an otherwise “bearish” fundamental scenario. When the market believes that under normal circumstances there would be enough oil, but at the same time sees that key transport routes are under threat, the price is formed not only on the basis of the supply and demand balance, but also on the basis of a security assessment. Such a pattern has been seen before in energy markets: a fundamental surplus does not guarantee low prices if traders assess that delivery is insecure or politically risky.
In the summary of its report for March, OPEC stated that the cartel’s reference basket rose in February to an average of 67.90 dollars per barrel, while the average Brent futures price in February amounted to 69.37 dollars. In just a few weeks after that, the market situation changed so much that the American EIA registered Brent at 94 dollars on March 9. That range shows well how quickly geopolitical events can push the market out of a relatively calm state and turn it into the main source of instability for the economy. In other words, not only the number changes, but also the mood of the market.
Pressure on transport, industry and household budgets
When oil becomes more expensive, the first and most visible blow goes to transport. Airlines, the shipping sector, road carriers and logistics companies are among the first to feel rising costs. Some companies try to temporarily cushion those costs with contracts and hedging against price increases, but in the case of a longer-lasting shock the room for absorption narrows quickly. That then affects almost everything: from airline ticket prices to the costs of delivering goods and raw materials. In a globalised economy, energy is no longer an isolated cost, but a thread that connects production, storage, transport and retail.
Industry is exposed to even more complex pressure. Energy-intensive sectors, such as chemical production, metallurgy, construction materials and part of the food industry, suffer not only from more expensive fuel but also from more expensive inputs related to processing and transport. Companies then have three unpleasant choices: reduce margins, raise prices or postpone investments. In practice, a combination of all three approaches often occurs, which means that the energy shock gradually becomes both a competitiveness problem and a growth problem.
For households, the effect is even more direct. A rise in fuel prices as a rule first changes mobility costs, but soon also affects a wider range of products and services. When transport bills are higher, the household budget leaves less room for discretionary spending, so demand declines in parts of the economy that at first glance have nothing to do with energy. That is precisely why an energy shock can simultaneously stimulate inflation and cool growth. For political and monetary authorities, this is one of the most difficult scenarios, because the same problem requires two mutually tense reactions.
Investors are now watching the duration of the shock, not only the price peak
In financial markets in recent days, there are fewer and fewer people who are satisfied with the question of whether Brent is at 90, 95 or 100 dollars. More important is how long it can remain significantly above the levels from the beginning of the year and how credible the calming scenario is. If investors believe that this is a temporary spike, stock and bond markets will absorb the shock more easily. But if they conclude that the disruption is longer-lasting, a revision of profit estimates, inflation, financing costs and economic growth follows.
This can also be seen in the way large institutions have been raising short-term price forecasts in recent days. The Wall Street Journal reported that Goldman Sachs again increased expectations for Brent, with a warning that a deeper and longer disruption in the Strait of Hormuz could also lead to significantly higher levels than those currently taken as the base scenario. Such estimates by themselves do not mean that the darkest scenarios will materialise, but they strengthen caution and signal that the market is no longer counting on a quick return to the old balance. That is exactly what changes the tone of the entire global economic debate.
From an investment standpoint, oil in moments like these becomes more than an ordinary market indicator. It turns into a reference point for assessing how much room central banks will have for a possible easing of monetary policy, how much consumption will weaken and whether the business sector will begin cutting employment and investment plans. Whenever the price of energy becomes unpredictable, the inclination toward caution grows, and caution is almost always the enemy of stronger economic momentum.
The world is more resilient than in the 1970s, but it is not immune
It is important, however, to keep a sense of proportion. Today’s world economy is not the same as in the decades when oil shocks had an even more devastating effect. Many countries today consume less oil per unit of GDP, have more diverse energy sources, more developed strategic storage and more sophisticated financial protection mechanisms. In addition, some large producers outside the OPEC+ group can somewhat mitigate the shortage on the market if disruptions do not turn into a complete blockade of key routes. All this means that the global economy is more resilient than it once was.
Still, resilience is not the same as immunity. In a world that is still strongly reliant on liquid fuels for transport, petrochemicals and part of industry, oil remains a commodity with a disproportionately large macroeconomic effect. Even when it does not cause a physical shortage, it can through expectations, prices and market uncertainty change the behaviour of companies and households strongly enough to slow the economy. That is why energy shocks are still viewed as events that can very quickly change investor sentiment, the political priorities of governments and the agenda of central banks.
In that sense, the biggest economic topic of the day really remains energy. As long as it is not clarified how long the disruptions in the Middle East will last and what their real effect on production and transport will be, the price of oil will remain the main global economic alarm. Every new jump will intensify fear of a return of inflationary pressures, and every easing will open room for cautious optimism. But at the moment it is clear that the world economy is once again living to the rhythm of the barrel, and that almost always means more expensive planning for states, companies and citizens.
