A month has passed since the Strait of Hormuz — one of the world”s most important energy arteries — was closed. A month in which the global oil market entered a stress regime, in which the price of a barrel rose sharply by 58%, and imported diesel rose by over 60%. And yet, in Romania, at the pump, the increase is “only” 24%, claims the Smart Energy Association (AEI). Thus, there will be further adjustments at the pump. If the blockade in Hormuz persists, if global stocks thin out and if the pressure on refineries increases, then prices may continue to rise, because the shock itself continues to deepen.
The first month was about absorption. What follows is about adapting under pressure. After a month of blockade, we are still in the “mild” phase, claims the AEI.
The hard part is not behind — it is very likely ahead
– 1–2 months – the system resists by inertia
– 2–4 months – the real stress begins
– 4–6 months – we enter the critical zone
There is a moment in any crisis when the numbers are no longer just numbers. They become alarm signals. In 2026, the diesel market has surpassed that moment. We are no longer talking about normal fluctuations, but about a structural reconfiguration of prices, in which geopolitics dictates the economy more than any theoretical model.
The three scenarios analyzed — probably, pessimistic and optimistic — are not simple forecasting exercises. They are, in fact, three variants of the same truth: cheap fuel has become a relic.
The “most likely” scenario is not reassuring at all
Oil at 130 USD/barrel and ARA diesel at 1,750 USD/ton do not represent an anomaly, but a new stress threshold for the economy. Romania, dependent on imports and vulnerable to the exchange rate, will feel this shock directly at the pump. Exceeding the 11 lei/l threshold is not just a symbolic figure — it is an inflection point. Transportation becomes more expensive, logistics chains become strained, and inflation gains a new fuel. Even with a subsequent decrease towards the end of the year, returning to “normal” means, in fact, accepting a new normal of average standard diesel in Romania above 10 lei/l.
The pessimistic scenario no longer seems so extreme
Oil at 200 USD/barrel is not an exaggeration in an unstable geopolitical context. In fact, history shows us that energy markets react disproportionately to risk, not to reality. The major problem is not just the price level, but the duration. Five months of tension can push the economy into a deadlock zone, carriers in difficulty, agriculture under pressure, reduced consumption. In this scenario, diesel at over 14 lei/l is no longer a hypothesis, but a direct consequence. And the return to 12 lei/l at the end of the year is not a relaxation, but a new anchor for prices.
The optimistic scenario is, paradoxically, the most misleading
Even if the conflict were to end quickly, the market would not return to previous levels. Inertia is too great, and the accumulated costs do not disappear overnight. Diesel below 9 lei/l becomes unlikely. This means that, even in the most favorable scenario, the consumer remains trapped in an area of high prices. Peace does not mean cheaper prices, but only slowing down the increase in prices.
The real problem is not the price, but the illusion of control
Domestic policies can marginally adjust the situation — excise duties, temporary caps, subsidies. But the reality is that Romania does not control the essential variables: energy routes, OPEC decisions, geopolitical risks. In a world where a flashpoint can destabilize global flows, the price at the pump becomes the result of decisions made thousands of kilometers away.
Without fiscal measures, 2026 will not bring cheap fuel in any scenario. The difference between the options is not between good and bad, but between bad and worse. And the real question is no longer “how much will diesel cost?” but “how much can the economy take before it collapses?”
In this context, adaptation becomes inevitable. Companies will have to rethink their costs, transportation will have to become more efficient, and consumers will have to accept that energy prices are no longer a stable variable, but a permanent risk.
Diesel is no longer just a product. It is the barometer of an unballanced world.
