In the first half of 2026, the global crude oil market experienced a period of extreme price volatility. Brent crude briefly surged to $118.35 per barrel in March, but quickly retreated as geopolitical premiums faded. By the close of June 30, 2026, WTI crude oil futures settled at $70.75 per barrel, while Brent crude closed at $73.15 per barrel. Within just a few months, international oil prices essentially gave back all gains made during the US-Iran conflict.
This complete cycle—from rapid rally to sharp decline—offers a valuable case study for understanding the pricing dynamics of the global crude oil market. How do geopolitical shocks impact oil prices? What is the interplay between supply recovery and demand destruction? And what signals does the changing inventory structure send?
How Geopolitical Premiums Shaped Oil Price Movements in the First Half of the Year
The US-Iran conflict that erupted at the end of February 2026 was the immediate catalyst for this round of oil price volatility. The Strait of Hormuz—a strategic chokepoint through which roughly 20% of global crude oil and liquefied natural gas flows—was disrupted for several months, cutting Middle Eastern crude output by nearly half. Before the conflict, London Brent crude futures traded around $70 per barrel, but surged to nearly $120 per barrel following the outbreak.
The fundamental reason geopolitical shocks have such a dramatic effect on oil prices lies in the irreplaceable role of the Strait of Hormuz in the global oil supply chain. A blockade means millions of barrels per day are instantly removed from the market, with no short-term alternatives to fill the gap. Panic over supply disruptions directly fueled a rapid expansion of risk premiums.
By mid-June, the US and Iran signed a memorandum of understanding, signaling easing tensions in the Strait of Hormuz. The US Treasury issued a 60-day general license authorizing Iranian oil production, delivery, and sales. As geopolitical risks subsided, expectations drove a sharp decline in oil prices. This process clearly illustrates the formation and unwinding of geopolitical premiums: accumulation tends to be swift and intense, but unwinding can accelerate just as quickly when expectations shift.
How Supply Recovery and Demand Contraction Reshaped Market Balance
Geopolitical conflict had far-reaching effects on both global oil supply and demand. On the supply side, the disruption in Middle Eastern oil reversed previous expectations of a global surplus. According to IEA data, global oil supply in 2026 is projected to decrease by 3.9 million barrels per day, falling to 102.4 million barrels per day. In May, global crude output dropped to 94.5 million barrels per day, down 13.6 million barrels per day from pre-conflict levels.
Supply recovery, however, is also accelerating. In early June, oil shipments through the Strait of Hormuz increased from 9.6 million barrels per day in May to about 12 million barrels per day. Morgan Stanley reports that last Thursday alone, 35 oil and gas tankers departed the Persian Gulf via the Strait, returning to the pre-conflict norm of 30–40 ships per day. The rapid restoration of Gulf crude supply directly eliminated panic over supply disruptions.
On the demand side, high oil prices themselves significantly suppressed consumption. IEA data shows that global oil deliveries in Q2 2026 fell by 5 million barrels per day year-over-year, with total demand expected to decline by 1.1 million barrels per day. The impact on China’s crude imports was particularly pronounced—May 2026 saw imports drop to 6.6 million barrels per day, the lowest since 2016. Combined, China and Japan’s crude imports decreased by nearly 6 million barrels per day. CICC estimates global oil supply will decline by about 4.3% year-over-year, with demand down 1.0%, resulting in a supply-demand shortfall of roughly 2.04 million barrels per day.
Why Record-Low Inventories Didn’t Prevent Oil Price Declines
A key question arises: Why did oil prices fall sharply even as global inventories dropped to historic lows?
US strategic crude reserves fell to 331.2 million barrels, the lowest since June 1983. Meanwhile, inventories at Cushing, the US delivery hub, dropped to 18.957 million barrels, a new low since 2014 and dangerously close to the operational warning line of 20 million barrels. Normally, Cushing holds about 40 million barrels. Preliminary IEA data shows global oil inventories have declined by an average of 3.8 million barrels per day since the conflict began.
This divergence between inventories and prices reflects a shift in market pricing logic. During geopolitical conflict, the core variable is "risk of supply disruption"—the lower the inventory, the greater the market’s vulnerability, and the higher the risk premium. Once supply recovery expectations are established, pricing logic shifts to "supply-demand rebalancing"—the focus turns to whether supply recovery outpaces demand restoration and whether inventories can be replenished in the foreseeable future.
CICC notes that the low inventory imprint following geopolitical shocks may be difficult to fully erase, providing a higher price floor for oil. In other words, extremely low inventories mean that even as geopolitical premiums fade, oil prices are unlikely to return to pre-conflict levels associated with a more relaxed market.
What Major Investment Banks’ Downgraded Oil Price Forecasts Signal
As expectations for the reopening of the Strait of Hormuz grew in June, several major investment banks sharply lowered their oil price forecasts. Morgan Stanley cut its Q3 2026 Brent crude spot price forecast by $15 to $75 per barrel, projecting further declines to $70 by Q3 2027. Goldman Sachs lowered its Q4 2026 Brent forecast to $80, with a 2027 average of $75. Citi reduced its Q3 and Q4 2026 forecasts to $75 and $70, respectively.
The core logic behind these revisions is that the Strait of Hormuz is reopening faster than expected, while the "high US supply + low Chinese demand" pattern remains unchanged. Morgan Stanley believes that as long as shipments through the Strait recover to about 65% of pre-conflict levels—roughly 11–12 million barrels per day—the global oil market can maintain basic equilibrium in 2027.
However, banks remain divided. Barclays maintains its forecast for Brent crude at an average of $100 per barrel in 2026. This divergence reflects the high uncertainty in current market pricing—geopolitical developments, supply recovery pace, and demand rebound strength are all unpredictable variables.
How OPEC+ Production Increases and Alliance Fractures Impact Supply Dynamics
On the supply side, OPEC+ production policy is also in focus. At its June 7 meeting, OPEC+’s seven member countries decided to raise production targets by 188,000 barrels per day starting in July. This marks the fourth consecutive monthly increase, with a cumulative rise of about 600,000 barrels per day.
Yet OPEC+’s actual output has not kept pace with quota increases. Due to export cuts by Gulf members, the group’s average April production was 33.19 million barrels per day, down sharply from 42.77 million barrels per day in February. This disparity underscores the gap between paper quota adjustments and real supply capacity in extreme geopolitical environments.
Deeper structural changes are underway. The UAE exited OPEC in May 2026. OPEC+’s current nominal spare crude capacity stands at about 2.5 million barrels per day, historically low. In 2027, with additional capacity pressure from the UAE and Iran, OPEC+ may face a tug-of-war between supporting oil prices and actively managing output. Internal alliance fractures and the pace of capacity releases will be key variables shaping medium-term supply dynamics.
Why Chronic Underinvestment May Provide Hidden Support for Oil Prices
Beyond short-term price swings, long-term supply constraints are equally critical. In 2025, global upstream oil and gas investment intensity fell to 0.38% of GDP, the lowest since 2004. Insufficient investment limits supply potential, and the reserve-to-production ratio of major global oil and gas companies dropped to its lowest since 2001.
North American shale oil has reached a production plateau. Faced with well depletion and rising costs, sustained output growth is increasingly difficult. CICC projects that over the next five years, non-OPEC+ oil supply elasticity will continue to decline, potentially providing long-term support for oil prices.
Additionally, a new cycle of global strategic oil reserve building may be underway. The US and other OECD countries are replenishing strategic reserves, while India, Southeast Asia, and other non-OECD countries are constructing oil reserve systems. Preliminary estimates suggest global restocking demand could reach 1–2 million barrels per day. This "restocking demand" will provide steady medium-term support for global oil markets.
Behind short-term price volatility, long-term supply constraints and reserve-building needs are quietly establishing a structural price floor for oil.
The Logic of Oil Market Volatility from a Trading Perspective
For market participants, understanding the full logic chain behind this round of oil price volatility is crucial. The rapid correction from $119 to $70 per barrel was essentially a systemic unwinding of geopolitical risk premiums, compounded by supply recovery expectations, real demand destruction, and macroeconomic uncertainty.
Several key factors warrant ongoing attention. First, geopolitical developments remain highly unpredictable—the implementation of the US-Iran agreement, full restoration of the Strait of Hormuz, and risks of renewed conflict could all trigger fresh volatility. Second, record-low inventories mean the market’s safety margin is extremely thin; any new supply shock could provoke even sharper price reactions. Third, macro trends in inflation and interest rates will continue to influence the financial pricing of crude oil.

Conclusion
In the first half of 2026, the global crude oil market underwent a complete price cycle driven by geopolitical shocks—from pre-conflict levels around $70 per barrel, to a peak near $120, and back to the $70 range. This round of volatility clearly demonstrated the mechanisms of geopolitical premium formation, accumulation, and unwinding.
At present, the market is in a phase where geopolitical premiums have largely been cleared and supply-demand dynamics are being repriced. Supply recovery is outpacing expectations, demand remains suppressed by high prices and macro factors, yet extremely low inventories provide a price cushion. Looking ahead, upstream underinvestment and strategic reserve-building may become structural supports for oil prices.
The future trajectory of oil prices will depend on the progress of restoring the Strait of Hormuz, OPEC+ production discipline, the pace of global demand recovery, and the evolution of geopolitical risks. In an environment of persistent uncertainty, a deep understanding of market logic is more valuable than simple price forecasts.
