How the 2026 Middle East conflict transformed an oversupplied oil market into the largest supply disruption in history, exposing the vulnerability of economies dependent on the world’s most strategically important commodity.
Few commodities have shaped the modern world as profoundly as oil. It powers transportation, sustains industries, influences inflation and determines the economic fortunes of nations. Yet, for all its commercial importance, oil has rarely been separated from geopolitics. From the 1973 oil embargo to the Gulf War, the global financial crisis and the Russia–Ukraine conflict, major disruptions have repeatedly demonstrated how quickly energy markets can become vulnerable to political and economic shocks.
In 2026, that vulnerability became impossible to ignore.
What began as a year of relatively comfortable global oil supplies turned into an unprecedented energy crisis following the outbreak of war involving the United States, Israel and Iran. The effective closure of the Strait of Hormuz, one of the world’s most important maritime energy corridors, disrupted international oil flows, forced producers to curtail output and sent crude prices sharply higher.
By March, the International Energy Agency (IEA) had described the crisis as the largest supply disruption in the history of the global oil market. Approximately 20 million barrels of crude oil and petroleum products that normally passed through the Strait each day had been reduced to a fraction of their usual volume.
The impact was immediate. Brent crude, the principal international oil benchmark, approached $120 per barrel during the initial market turmoil. The consequences extended beyond energy traders and petroleum producers, threatening higher transportation costs, industrial expenses and inflation across oil-importing economies.
For countries dependent on imported energy, the crisis exposed a fundamental economic reality: the price of oil is determined not only by how much the world produces and consumes, but also by whether that oil can reach its destination.
From Strategic Resource to Geopolitical Instrument
The relationship between oil and geopolitical power predates the modern Middle Eastern energy industry.
Commercial petroleum production expanded during the nineteenth century, but the discovery of major reserves in the Middle East fundamentally changed the global energy landscape. One defining milestone came in 1938, when commercially viable oil was discovered at Dammam No. 7 in Saudi Arabia, laying the foundation for the development of what would become Saudi Aramco.
As petroleum replaced coal in important areas of transportation and industrial activity, control over oil production and trade became an increasingly significant strategic advantage.
The 1973 Arab oil embargo demonstrated that energy supplies could be used to exert geopolitical pressure. Restrictions on exports contributed to sharp price increases and economic difficulties across importing nations. The 1990 Iraqi invasion of Kuwait created another major supply shock, while the 2008 financial crisis illustrated how oil prices could collapse when global demand deteriorated.
More recently, the COVID-19 pandemic caused an extraordinary contraction in petroleum consumption, with West Texas Intermediate (WTI) futures briefly turning negative in April 2020 because of exceptional conditions surrounding contract expiry and storage availability.
The Russia–Ukraine war in 2022 added another dimension, disrupting established energy trade relationships and forcing governments and businesses to reconsider supply security.
These episodes reveal an important distinction. Oil prices respond not only to physical shortages but also to expectations of future supply, changes in demand, trade restrictions and the risks associated with transporting energy across international borders.
The events of 2026 brought these vulnerabilities together in one of the most consequential oil-market disruptions in modern history.
The Calm Before the Crisis
At the beginning of 2026, the international oil market appeared relatively well supplied.
According to the IEA’s assessment of global oil balances, worldwide oil supply exceeded demand by approximately 1.4 million barrels per day on average in 2025. The surplus expanded beyond 2 million barrels per day during the second half of the year, contributing to inventory accumulation.
The additional supply reflected a combination of production increases, including the gradual unwinding of OPEC+ output restrictions, and growth from producers outside the alliance.
For oil-importing economies, the prospect of abundant supplies offered some relief from the inflationary pressures associated with expensive energy.
Brent crude averaged approximately $66.60 per barrel in January 2026, according to EIA historical price data. Although prices fluctuated as geopolitical tensions intensified, the market had not yet experienced the physical supply disruption that would emerge weeks later.
This distinction matters because the market entered the conflict with substantial inventories and expectations of relatively comfortable supply.
The fundamental question was no longer simply whether sufficient oil existed. It was whether producers could continue delivering it to international buyers.
That question became urgent on 28 February.
February 28: The Conflict That Changed the Oil Market
On 28 February 2026, the United States and Israel launched joint military strikes against Iran, triggering a regional escalation with immediate consequences for international energy markets.
The Strait of Hormuz quickly became the central concern.
Located between Iran and Oman, the narrow waterway connects the Persian Gulf to the Gulf of Oman and the wider international shipping network. It provides an essential export route for several of the world’s largest petroleum-producing countries.
According to the IEA, approximately 15 million barrels of crude oil and 5 million barrels of petroleum products normally transited the Strait each day before the conflict, together equivalent to around one-fifth of global oil consumption.
The disruption therefore threatened far more than Iran’s own petroleum exports. It placed a substantial share of the Middle East’s international energy trade at risk.
As maritime traffic through Hormuz slowed dramatically, producers faced an increasingly difficult logistical problem. Oil that could not be exported began accumulating in storage facilities, eventually forcing production reductions.
The IEA’s March 2026 Oil Market Report estimated that Gulf countries had curtailed at least 10 million barrels per day of oil production, including crude oil, condensates and natural gas liquids.
International markets reacted sharply. Brent futures approached $120 per barrel during the initial disruption before retreating to approximately $92 at the time of the IEA’s 12 March assessment.
The volatility reflected more than the immediate loss of available barrels. Traders were attempting to price an uncertain combination of shipping restrictions, production outages, infrastructure risks and the possibility of a prolonged conflict.
The world’s most important oil transit corridor had effectively become a geopolitical pressure point.
March and April: When Supply Disruption Became a Global Crisis
As the conflict continued into March, the scale of the supply shock became clearer.
The US Energy Information Administration estimated that six Gulf producers—Iraq, Saudi Arabia, Kuwait, the United Arab Emirates, Qatar and Bahrain—collectively shut in approximately 7.5 million barrels per day of crude oil production during March.
The agency expected those production curtailments to increase to approximately 9.1 million barrels per day in April.
Brent crude averaged approximately $103 per barrel in March, reflecting the severity of the disruption and the growing uncertainty surrounding the restoration of maritime traffic.
The crisis also exposed the limitations of conventional supply responses.
Under normal circumstances, higher prices encourage producers with available capacity to increase output. However, additional production offers limited immediate relief when export routes remain constrained.
The problem was therefore not simply insufficient production capacity. It was the inability to move available oil from producing countries to consuming markets.
The second quarter became particularly volatile.
According to the EIA’s July 2026 market analysis, front-month Brent futures reached a high of $118 per barrel on 29 April. During April and May, the average daily price swing was approximately $4 per barrel, compared with around $1 during the same months in 2025.
That fourfold increase in average daily price movements illustrated the extraordinary uncertainty confronting the market.
The implications extended beyond crude oil itself. Disruptions to petroleum product exports and refining operations placed additional pressure on diesel, aviation fuel and liquefied petroleum gas markets.
The IEA’s assessment of the energy shock warned that higher energy prices could place significant pressure on households, businesses and economic activity.
A disruption concentrated in one maritime corridor was transmitting costs across the global economy.
May and June: Diplomacy Brings Relief, but Not Stability
By May, diplomatic negotiations and expectations of renewed shipping activity began influencing the direction of oil prices.
The market increasingly responded to the possibility that the disruption might gradually ease, allowing production and exports to recover.
Between 18 May and 17 June, Brent prices declined by an average of more than $1 per barrel per day, according to the EIA.
A significant development followed on 17 June, when the United States and Iran signed a memorandum of understanding aimed, among other objectives, at facilitating the resumption of traffic through the Strait of Hormuz.
As tanker movements increased and expectations of restored oil flows strengthened, international prices declined.
Brent futures fell to approximately $72 per barrel on 26 June, their lowest level of the second quarter.
The decline demonstrated how rapidly the geopolitical risk premium embedded in oil prices could diminish when markets anticipated improved supply conditions.
However, lower prices did not mean that the underlying vulnerabilities had disappeared.
Restoring petroleum production and export operations after a major disruption is not instantaneous. Producers must rebuild operational capacity, shipping networks must resume normal activity, and buyers must regain confidence in the reliability of supply routes.
Moreover, oil markets remain forward-looking. Even when current supplies improve, expectations of renewed disruption can keep prices elevated.
The events of June therefore represented a period of partial market relief rather than a permanent resolution of the energy crisis.
July to October: The Return of the Energy Shock
The optimism surrounding June’s diplomatic developments proved short-lived.
Renewed military strikes in July brought geopolitical risk back into oil pricing. According to the EIA’s third-quarter review, front-month Brent futures began July at approximately $72 per barrel, but climbed above $100 by 23 July following renewed hostilities.
Prices subsequently fluctuated as markets weighed the possibility of further disruptions against efforts to restore regional exports.
By September, the crisis had entered another dangerous phase.
Attacks on Saudi Arabia’s East-West oil pipeline temporarily interrupted one of the region’s most important alternative export routes. The pipeline had allowed Saudi Arabia to transport crude oil to the Red Sea, reducing its dependence on the Strait of Hormuz.
The disruption demonstrated that even infrastructure designed to bypass a geopolitical chokepoint could become vulnerable to the wider conflict.
According to the EIA’s October 2026 Short-Term Energy Outlook, Brent spot prices averaged approximately $114 per barrel in September, up $23 from August. On 15 September, the daily Brent spot price reached as high as $131 per barrel as buyers scrambled to secure supplies following the pipeline disruption.
The recovery in oil exports remained uneven.
The IEA’s October Oil Market Report estimated that global oil supply increased by 2.5 million barrels per day in September to 102.3 million barrels per day. Yet the agency warned that renewed attacks on energy infrastructure and maritime traffic threatened to reverse those gains.
More importantly, the recovery in crude oil shipments did not translate into an equivalent recovery in refined petroleum products.
Middle Eastern refined product exports reached approximately 1.9 million barrels per day in September, compared with 4.7 million barrels per day before the conflict.
This imbalance placed particular pressure on diesel markets.
The IEA reported that global diesel prices had exceeded $200 per barrel in September before easing, creating significant additional costs for transportation, manufacturing and other fuel-dependent activities.
The distinction between crude oil and refined fuel prices became increasingly important. Even when crude production recovered, shortages of specific petroleum products continued to affect the real economy.
By October, the market was no longer responding to a single supply disruption. It was confronting a prolonged period of uncertainty involving damaged infrastructure, constrained shipping routes, elevated freight costs and depleted inventories.
OPEC’s Changing Influence and the Search for Alternative Supplies
The crisis also coincided with an important structural development in the global oil industry.
On 28 April 2026, the United Arab Emirates announced its decision to leave the Organization of the Petroleum Exporting Countries (OPEC), effective 1 May.
The decision ended nearly six decades of membership and raised questions about the future influence of coordinated production restrictions.
According to the EIA, the UAE produced approximately 3.4 million barrels of crude oil per day in 2025 and possessed an estimated effective production capacity of 4.2 million barrels per day.
Its departure reduced OPEC’s share of global crude oil production and introduced another source of uncertainty into the longer-term supply outlook.
However, the immediate market implications were constrained by the conflict itself.
Additional production capacity could not fully compensate for the inability to transport oil through disrupted export routes.
Saudi Arabia and the UAE were comparatively better positioned than several neighbouring producers because of their investment in alternative pipelines.
Saudi Arabia’s East-West pipeline provided access to the Red Sea, while the UAE’s Abu Dhabi Crude Oil Pipeline connected production facilities to Fujairah outside the Strait of Hormuz.
These routes helped reduce some of the disruption, but they could not entirely replace normal shipping flows through Hormuz.
The crisis also encouraged buyers to seek additional supplies from producers outside the Middle East.
The IEA identified increased production from countries including the United States, Brazil, Kazakhstan, Venezuela and Nigeria as an important factor in partially offsetting the Gulf supply shortfall.
Nevertheless, alternative production and transportation routes involved additional logistical and commercial costs.
The events of 2026 demonstrated that energy security depends not only on the quantity of available oil but also on the geographic diversity, accessibility and resilience of supply infrastructure.
The Economic Cost: Why Oil-Importing Countries Pay the Price
For oil-importing economies, higher international prices create pressures that extend far beyond the petroleum industry.
Crude oil and refined petroleum products are essential inputs for transportation, electricity generation, agriculture and industrial production.
When prices rise, importers must spend more foreign currency to secure supplies. Businesses face higher operating costs, while governments must decide how much of the additional burden should be absorbed through subsidies, public finances or domestic fuel prices.
The effects can gradually spread through the economy.
Higher diesel prices increase freight and distribution costs. More expensive transportation can raise the delivered prices of food and consumer products. Industrial producers face higher energy expenses, potentially affecting profitability and competitiveness.
These pressures can be especially difficult for developing economies with limited foreign exchange reserves and significant dependence on imported energy.
Bangladesh: A Direct Exposure to the Hormuz Crisis
Bangladesh provides a clear example of how geopolitical developments thousands of kilometres away can affect domestic economic conditions.
In April 2026, Energy Minister Iqbal Hassan Mahmood Tuku told parliament that approximately 20–23% of Bangladesh’s imported fuel oil normally passed through the Strait of Hormuz.
According to The Daily Star’s report on the minister’s statement, the country’s crude oil imports from Saudi Arabia and the UAE normally travelled through the waterway before being processed at Eastern Refinery.
The exposure was therefore both direct and substantial.
The financial consequences became increasingly visible in Bangladesh’s import statistics.
According to Bangladesh Bank data , the country’s fuel oil import expenditure reached approximately $10.63 billion in FY2025–26, compared with $5.14 billion in FY2024–25.
That represented an increase of approximately 107% year-on-year.
Fuel oil accounted for approximately 14.13% of Bangladesh’s total merchandise import expenditure during FY2025–26.
The increase cannot be attributed entirely to international price movements. Higher import volumes also contributed, while the fiscal year included several months before the conflict began.
Nevertheless, the figures illustrate the scale of Bangladesh’s exposure to changes in international energy costs.
For an economy dependent on imported petroleum, a prolonged period of elevated prices can intensify foreign currency requirements and complicate inflation management.
It can also place pressure on energy-intensive businesses, particularly manufacturers and logistics operators already managing rising operating expenses.
The wider consequences depend on several factors, including the exchange rate, the government’s domestic fuel-pricing policy, procurement arrangements and the extent to which businesses pass additional costs on to consumers.
The lesson is clear: Bangladesh’s energy security is closely connected to developments in international commodity markets and maritime trade routes over which it has little direct control.
An Oil Market Still Searching for Stability
As 2026 approaches its final months, the international oil market remains deeply uncertain.
The IEA’s October assessment projected that global oil supply would average approximately 100.7 million barrels per day in 2026, a decline of 5.8 million barrels per day from the previous year.
At the same time, global oil demand was forecast to decline by approximately 2.6 million barrels per day during the year, reflecting the effects of high prices, supply constraints and weaker economic activity.
This combination presents an unusual challenge.
Under normal circumstances, weaker demand tends to ease upward pressure on oil prices. However, when production, refining and transportation remain severely constrained, falling consumption may not be sufficient to restore market stability.
The IEA estimated that global observed oil inventories at the end of September were approximately 509 million barrels below their pre-war levels.
Such inventory depletion reduces the market’s ability to absorb further disruptions.
The EIA’s October forecast projected that Brent crude would average approximately $105 per barrel in the fourth quarter of 2026, while acknowledging considerable uncertainty surrounding the duration of supply restrictions.
A sustained recovery would require more than diplomatic announcements or temporary increases in tanker movements.
It would depend on the restoration of reliable shipping routes, the recovery of disrupted production and refining capacity, and the rebuilding of global petroleum inventories.
Until those conditions improve, oil markets are likely to remain vulnerable to sudden geopolitical developments.
The Price Beyond the Barrel
Oil has always been more than a commodity. It is a strategic resource that connects international politics with domestic economic realities.
The events of 2026 have demonstrated how quickly those connections can become disruptive.
A market that entered the year with expectations of ample supply was transformed by conflict into one facing extraordinary production losses, maritime restrictions, price volatility and mounting economic costs.
For producers, the crisis exposed the limitations of relying on geographically concentrated export infrastructure. For importing countries, it revealed the risks of dependence on energy supplies vulnerable to geopolitical disruption.
For businesses and consumers, the consequences were more immediate: higher fuel costs, expensive transportation, pressure on industrial production and increased uncertainty about future prices.
The year also challenged the assumption that sufficient global production capacity necessarily guarantees energy security. Oil may exist in abundance, but that abundance offers little protection when the infrastructure connecting producers to consumers becomes inaccessible.
Ultimately, the most important lesson of 2026 is not simply that war can make oil expensive.
It is that the global economy remains deeply dependent on a commodity whose movement can be interrupted by political decisions, regional conflict and fragile international trade routes.
The price of oil may be quoted in dollars per barrel, but the true cost of its disruption is measured across economies, industries and everyday lives.
