The same market is pricing immediate scarcity and medium-term oversupply, a contradiction that matters for inflation, investment and producer strategy.
The Middle East war has sharply deepened the expected 2026 oil deficit, but analysts still expect a sizeable surplus in 2027. Reuters reported that analysts doubled their average estimate for the 2026 deficit to 1.5 million barrels per day while continuing to forecast a 1.9 million barrel-per-day surplus next year.
That split outlook explains why the oil market feels unstable. Traders are pricing a near-term shock from the US-Iran conflict, Hormuz disruption, higher insurance costs and tanker delays. At the same time, they are looking ahead to more supply from the United States, Latin America and OPEC+ producers, combined with weaker demand growth in China. Scarcity and oversupply can both be true if the time horizon changes.
EU Global has recently examined Hormuz disruption and the way Gulf war costs are moving into container trade. The Reuters poll adds a quantitative frame. This is not only about daily Brent movements. It is about whether a war-driven deficit in 2026 will be followed by a supply overhang in 2027.
The 2026 deficit is driven by disruption risk. The Strait of Hormuz handles a large share of seaborne crude and LNG flows. Even partial disruption raises costs because tankers require war-risk insurance, shipping schedules become less predictable and buyers build precautionary inventories. The price of reliability rises before physical shortages become visible.
War also changes behaviour. Producers may hold back cargoes, buyers may seek alternative grades, refiners may adjust runs and governments may release or rebuild strategic stocks. Each decision affects the balance. In a tight market, small logistical delays can produce price spikes because there is little spare flexibility.
The 2027 surplus comes from a different logic. High prices encourage production, especially from non-OPEC sources. US shale responds faster than conventional projects, though not instantly. Brazil, Guyana, Canada and other producers are adding capacity. OPEC+ may also face pressure to restore volumes if members want revenue. If supply expands just as war disruption eases and demand softens, the market can flip from shortage to glut.
China is the demand wildcard. Slower Chinese growth, weak refining runs or faster electrification can reduce oil-demand expectations. Yet China can also become a swing refiner if it raises throughput to supply diesel, gasoline or jet fuel. Recent EU Global analysis of China’s refining capacity showed how Beijing’s choices can affect product markets even when crude supply remains uncertain.
The investment signal is therefore confused. Oil companies may benefit from high prices in 2026, but they may hesitate to sanction expensive long-cycle projects if a 2027 glut is expected. Refiners may earn strong margins during disruption, but overinvesting in capacity could be dangerous if demand growth weakens. Governments may want more supply for energy security, while climate policy points in the opposite direction.
For central banks, the two-year split complicates inflation decisions. A near-term oil shock can push headline inflation higher and damage consumer confidence. But if futures markets and analyst polls point to a 2027 surplus, policymakers may be reluctant to overreact. The risk is that temporary energy shocks still become persistent if they feed wages, transport costs and food prices.
For OPEC+, the outlook is strategically difficult. If the group restrains output to defend prices during a war shock, it may cede market share to non-OPEC producers. If it raises output too quickly, it may accelerate the 2027 surplus. The group must balance immediate revenue against longer-term price stability while some members face fiscal pressure.
For Europe, the problem is less production than exposure. Europe imports most of its oil and many refined products. A 2026 deficit raises costs for households, airlines, agriculture and industry. A 2027 glut may bring relief, but it may also arrive after inflation, subsidies and political damage have already occurred. Time matters to politics more than annual averages.
The apparent contradiction in the Reuters poll is therefore the key insight. The oil market is not sending one signal. It is sending two: the war has made the current year tighter, but structural supply and demand trends may still loosen the next one. Policymakers and companies that plan only for today’s shortage may be caught by tomorrow’s surplus. Those that wait for tomorrow’s surplus may suffer today’s shock.
The result is a market built on unstable expectations. The war decides the immediate balance. Investment, OPEC+ discipline and Chinese demand decide what follows. Between the two sits a year in which energy security and price risk may pull governments in opposite directions.
