Oil back above $100: a new energy shock puts inflation back at the center of the global economy
The price of oil has once again broken through the psychologically and economically important threshold of $100 per barrel, and the new rise is coming at a time when central banks and governments had only just begun to count on a gradual easing of inflationary pressures. The latest disruptions linked to the war around Iran and interruptions to energy flows through the Strait of Hormuz have returned energy to the key themes of the world economy. What only a few months ago seemed like a gradual calming of commodity markets is now once again turning into a source of uncertainty for households, companies, transport operators, food producers, and economic policymakers.
Markets are not reacting only to the level of the barrel price itself, but also to the assessment of how long the disruption might last. It is precisely the duration of the shock that is crucial: a short-lived spike may remain limited to financial markets and traders' margins, but a longer period of more expensive energy almost regularly spills over into retail fuel prices, transport costs, logistics, heating, industrial production, and, indirectly, food. That is why the current rise in oil is no longer just a geopolitical story, but a topic that directly concerns inflation, interest rates, economic growth, and living standards.
The Strait of Hormuz as a sensitive point of global supply
The center of current concern is the Strait of Hormuz, one of the most important maritime chokepoints for global energy trade. Through this narrow passage, according to data from the International Energy Agency, an average of around 20 million barrels of crude oil and petroleum products per day passed in 2025, or approximately a quarter of total global seaborne oil trade. At the same time, a large part of the world's trade in liquefied natural gas also passes through the same corridor, especially from Qatar and the United Arab Emirates. When traffic of that kind is threatened, even partially, the market does not wait for oil to physically disappear; it is enough for the perception of risk to rise for prices to start moving sharply upward.
That is exactly what is happening now. The International Energy Agency announced that the war in the region, which began on February 28, disrupted oil and gas flows through the Strait of Hormuz and caused the largest supply disruption in the history of the global oil market. The agency also stated that global liquefied natural gas supply has been reduced by about 20 percent because of the situation in the Middle East. Such an assessment in itself explains why the market reacted sensitively and investors began speaking about the possibility of a new energy shock comparable to earlier crisis episodes.
For the economies of Asia, the risk is especially pronounced because that is where most of the oil passing through the Strait of Hormuz ends up. However, the consequences do not stop in Asia. Europe may not directly import the largest share of that volume, but it is deeply connected to global markets for energy, maritime transport, industrial inputs, and cargo insurance. Because of this, every major disruption in the Persian Gulf almost automatically becomes a global cost shock.
Why the $100 threshold matters so much
The $100 threshold is not important only because of symbolism. It is the level at which energy once again begins to enter more forcefully into the calculations of central banks, finance ministries, and large industrial systems. While the World Bank was still estimating in October 2025 that 2026 should be a year of lower commodity prices, with an expected decline in overall commodity prices of 7 percent in both 2025 and 2026, geopolitical escalation has shown how quickly such projections can be reversed when a security shock hits key energy routes.
In other words, until recently the market was counting on more abundant supply and weaker demand growth, but war risk has the power to change the relationship between supply and expectations in a very short time. When a barrel goes above $100, the market's message is not only that oil is more expensive, but that supply risks have risen to a level at which emergency measures, strategic reserves, and crisis scenarios once again come to the fore. In such an environment, volatility becomes almost as important as the price itself.
Recent market reactions have shown exactly that: a sharp rise in oil prices was accompanied by a fall in some stock indices and an increased shift of capital into safer assets. Investors are not looking only at the energy sector. They are assessing whether more expensive energy will once again slow consumption, raise business costs, and delay the expected easing of monetary policy in some of the largest economies.
From gas stations to stores: how the shock spills over into inflation
The connection between energy and inflation is not theoretical, but very concrete and multilayered. Drivers and transport operators see the first transmission channel: more expensive crude oil as a rule spills over into gasoline, diesel, and jet fuel. The second channel hits industry, because higher fuel and energy costs make production and distribution more expensive. The third channel comes through food, since agriculture and the food chain depend on fuel, fertilizer, cooling, storage, and transport. When energy becomes more expensive, the price of everything that needs to be produced, transported, or kept in the cold chain often rises as well.
In its research on the energy origins of the global inflation surge, the International Monetary Fund warns that energy plays an important role in inflation dynamics through direct and indirect channels. In its analyses of the transmission of energy shocks to inflation, the European Central Bank shows that increases in gas prices and other energy sources do not remain confined within the energy sector, but are transmitted through production costs and secondary effects to a wider range of prices. That means the problem is not only one higher bill at the gas station, but the possibility that the cost pressure will spread throughout the entire economy.
That is why special attention is being paid to whether the rise in oil prices will remain a short episode or turn into a more lasting upward trend. If energy commodities stay expensive for long enough, central banks could once again find themselves in an uncomfortable position: inflation would be stickier than expected, while economic growth would be weaker at the same time. It is precisely this combination that is bringing back into public debate the concept of stagflation, a scenario in which rising prices and a slowing economy act simultaneously.
G7, strategic reserves, and the question of the political response
Because of the scale of the risk, the energy market is no longer monitored only through daily stock exchange reports, but also through the political decisions of the largest economies. The G7 and other Western countries are considering which instruments they have at their disposal if disruptions persist. In the public sphere, there is already talk of possible coordinated reactions, from the use of strategic reserves to additional measures to stabilize supply and calm market expectations.
The most concrete institutional move so far has come from the International Energy Agency, whose members on March 11 unanimously agreed to the largest-ever release of emergency oil stocks to mitigate market disruptions. The very fact that the largest such intervention in the agency's history has been activated says enough about the assessment of the seriousness of the situation. Such measures cannot entirely remove geopolitical risk, but they can buy time, ease panic, and show that Western states have certain protective mechanisms at their disposal.
However, markets know that strategic reserves are not a permanent solution. They can ease a short-term shortage or cushion a sudden rise in prices, but they cannot replace a stable and secure flow of energy if a key maritime route is under prolonged threat. That is why every political response depends on one basic question: will the security situation in the Middle East calm down quickly enough for shipping flows to normalize, or is this a disruption that will last for weeks and months.
The greatest pressure on transport, industry, and food
The sectors that feel the consequences first are already well known. Airlines, shipping companies, and logistics firms are among the first to calculate new costs because fuel makes up a large part of their operating expenses. More expensive maritime transport further raises the prices of insurance, rerouting, and delivery times. Industries operating with thin margins, especially the chemical, food, construction, and part of manufacturing production sectors, are facing pressure to pass part of the cost on to customers.
The food chain is particularly sensitive because almost all inflationary channels come together in it: energy for production, fuel for mechanization, transport, packaging, storage, and cooling. That is why investors and analysts rightly warn that the oil shock does not remain in the oil market. If it lasts, it may appear in the prices of airline tickets, container transport, supermarkets, and services. It is precisely this broad spread of the cost that makes energy shocks politically and socially sensitive.
For households, that means a very tangible effect: higher fuel prices reduce disposable income, while more expensive goods and services put additional pressure on consumption. For governments, this raises the question of whether they should once again resort to subsidies, tax corrections, or targeted support measures. But such measures have a fiscal cost, so the problem quickly turns from an energy issue into a budgetary one as well.
Central banks under pressure again
One of the reasons why markets are following the rise in oil so nervously is the fact that monetary authorities have still not fully closed the inflation chapter. In its updated projections, the International Monetary Fund still starts from a scenario in which global inflation is slowing, with an estimate that in 2026 it should amount to 3.7 percent at the global level. But such projections always include a warning that they can be changed by new external shocks, and energy is among the most important.
If the current rise in energy prices proves persistent, central banks could be forced to keep more restrictive interest rates for longer than markets expected at the beginning of the year. That would hit lending, investment, and demand for real estate, but also increase the cost of servicing public and private debt. In other words, more expensive oil does not mean only more expensive fuel; it can also change the price of money.
The timing of such a shock is especially sensitive. The global economy entered 2026 with the assumption that inflation would continue to weaken and that growth would remain moderate. A new disruption in the energy market threatens precisely that balance. The longer the period of high oil prices, the greater the probability that forecasts will once again be revised downward for growth and upward for inflation.
Markets are actually assessing the duration of the crisis
At this moment, the crucial issue is not only how much a barrel costs today, but what the market believes will happen over the next few weeks. If security conditions improve and shipping through the Strait of Hormuz begins to normalize, prices can retreat relatively quickly. But if disruptions persist, or spread to additional infrastructure and producers, the price increase could be more prolonged and more serious.
That is why analysts are observing several variables at the same time: the physical volume of exports from the Gulf, the security of tanker routes, the availability of alternative routes, the behavior of insurers, the willingness of states to release reserves, and the reaction of major producers. It is also not unimportant that alternative routes cannot fully replace the Strait of Hormuz. According to IEA data, the available bypass pipeline capacity amounts to approximately between 3.5 and 5.5 million barrels per day, which is significantly less than the volume that normally passes through that corridor.
It is precisely because of that gap that the market in such situations remains sensitive to every new piece of news. When global supply is tight, or there is fear that it could become tight, the price does not react linearly, but in jumps. This further complicates planning in the real sector, because companies do not know whether they will face only temporary instability or a change in the cost structure for the entire year.
From geopolitics back to everyday economics
The war around Iran has once again shown how energy remains a fundamental economic story, and not just a security or diplomatic issue. In the years after the major inflationary shocks, many governments and central banks wanted to believe that the worst part of the energy pressure was behind them. However, developments in the Middle East are a reminder that the global economy remains sensitive to a few narrow transport and political chokepoints through which a huge part of the world's energy passes.
That is why the rise in the oil price above $100 per barrel cannot be viewed as an isolated market incident. It once again raises the question of how resilient the global economy really is to external shocks, how quickly inflation can revive, and how ready governments are to react without further undermining public finances. In the coming days and weeks, the main question will not only be whether oil will remain expensive, but whether the new energy shock will spill over into the everyday prices of transport, food, and life in general. That is precisely why energy once again stands at the center of the global economy, and not just geopolitics.
