The global oil market has already survived one of the largest supply disruptions in its history, but the mechanisms that prevented a full-scale energy crisis are now under growing pressure. Renewed conflict involving Iran, attacks on tankers in the Red Sea, restricted movement through the Strait of Hormuz and disruptions to exports from Kazakhstan are tightening several parts of the supply system at the same time.
The result is no longer limited to volatile futures prices. Physical crude cargoes are becoming significantly more expensive, refiners are competing for replacement supplies and tankers are being forced onto longer routes. According to Reuters’ latest physical oil market analysis, some crude grades approached $110 per barrel as buyers searched for immediately available alternatives.
That shift matters because physical markets reveal the actual cost of obtaining and delivering oil. Futures contracts can fall rapidly on diplomatic headlines, but refiners still need real barrels at specific locations and within specific timeframes. When those barrels become difficult to secure, the market begins moving from fear-driven volatility toward genuine physical tightness.
The Constraints That Previously Protected the Market
The oil market entered the conflict with several powerful defences. Global supply had been running above demand, commercial inventories were relatively strong, China had accumulated substantial reserves and major consuming nations held emergency stocks.
The International Energy Agency’s analysis of the Hormuz disruption estimated that the market had entered 2026 with an expected surplus of approximately 3.7 million barrels per day. Global storage had reached about 8.2 billion barrels, creating a cushion that allowed countries to absorb the first wave of lost Middle Eastern supply.
China also reduced crude purchases substantially as domestic demand weakened and stored supplies became available. At the same time, the United States increased exports, Saudi Arabia redirected crude through its East-West pipeline and the United Arab Emirates relied on infrastructure that bypassed the Strait of Hormuz.
Emergency stock releases provided another critical defence. IEA member countries authorised a record release of 400 million barrels, while governments, companies and major importers collectively withdrew enormous quantities from storage. These measures did not replace all the disrupted supply, but they prevented the shortage from immediately reaching consumers.
Those protections explain why oil prices did not reach the extreme levels initially predicted. However, they were designed to absorb a temporary emergency, not an open-ended conflict.
Emergency Reserves Are Not an Unlimited Supply Source
The most serious change is the depletion of readily available inventories. Reuters estimated that the world absorbed the loss of more than one billion barrels after the war began, partly because governments and companies released stored oil at an exceptional rate.
The same Reuters investigation into depleted oil buffers found that the market’s success in avoiding fuel shortages had created a new vulnerability. Storage levels had fallen, emergency reserves would eventually need to be replenished and the system had less protection against another prolonged disruption.
The July IEA Oil Market Report showed that OECD inventories continued declining in June. Although total observed stocks rose because more oil was being transported at sea, onshore inventories remained under pressure, and government releases accounted for a significant portion of the available supply.
Oil stored aboard tankers cannot always replace oil located near a refinery. Distance, crude quality, port access and delivery schedules determine whether a barrel can solve an immediate shortage. A large headline inventory figure can therefore hide tightening conditions in particular regions and fuel markets.
Two Major Shipping Chokepoints Are Now Under Pressure
The oil market previously relied on alternative routes to reduce its exposure to the Strait of Hormuz. Saudi Arabia increased exports through the Red Sea, while some Gulf producers used pipelines and ports located outside the strait.
That strategy becomes less effective when the Red Sea also turns dangerous. Attacks by Yemen’s Houthi movement have increased risks around Bab el-Mandeb, the narrow passage connecting the Red Sea to the Gulf of Aden. Tankers carrying Saudi oil have reportedly changed course, while some shipments have been redirected around the African continent.
A voyage around Africa adds time, fuel consumption, vessel demand and freight expense. Reuters reported that some shipments using the longer route could face almost an additional month of travel compared with the usual passage through Bab el-Mandeb. Saudi Aramco has also offered additional cargoes through Egypt’s Mediterranean port of Sidi Kerir as buyers search for safer arrangements.
The simultaneous pressure on Hormuz and Bab el-Mandeb represents a dangerous change. One route can no longer function as a simple substitute for the other. Disruption at both chokepoints reduces the market’s ability to redirect supply without major cost or delay.
Physical Oil Prices Are Sending a Stronger Warning
Benchmark futures remain important, but physical crude prices provide a clearer picture of what refiners are experiencing. Dated Brent, which helps price much of the world’s physical oil trade, reached $105.70 per barrel on July 23. North Sea Forties crude subsequently rose to $108.77.
Premiums for Middle Eastern oil also increased sharply. Dubai and Oman crude premiums more than doubled, while Abu Dhabi’s Murban grade reached its strongest premium since early April. Buyers in Japan and South Korea began searching more aggressively for Atlantic Basin supplies as access to customary Middle Eastern cargoes became less reliable.
These movements suggest that the market is becoming tight in specific crude grades and delivery windows. The issue is not simply whether enough oil exists globally. The more urgent question is whether the correct type of crude can reach the correct refinery at the required time.
Refiners cannot replace every disrupted barrel with any available grade. Differences in sulfur content, density and processing requirements can limit substitution. As a result, shortages in one category can create unusually high premiums even when the broader market appears adequately supplied.
Insurance and Freight Costs Are Becoming Part of the Oil Price
Military danger affects the oil market before a tanker is physically damaged. Insurers increase premiums, shipowners demand greater compensation and some vessels avoid high-risk areas entirely.
Earlier in the conflict, Reuters reported on surging maritime insurance costs as war-risk coverage became more expensive. A rate equal to 3% of a tanker’s value could produce a premium of approximately $7.5 million for a vessel worth $250 million, compared with a fraction of that amount before the fighting.
Those costs eventually reach refiners, fuel distributors, airlines, manufacturers and consumers. Even when oil production remains operational, the delivered price rises because transportation has become more dangerous and complicated.
Shipping risk can also reduce the effective size of the tanker fleet. Longer journeys keep vessels occupied for additional weeks, meaning fewer ships are available for other cargoes. The market must then pay higher freight rates to secure the remaining capacity.
Additional Supply Disruptions Are Removing Alternatives
The Middle East is not the only source of pressure. Kazakhstan reportedly reduced oil production after suspected Ukrainian drone attacks forced operations to stop at its main export terminal on the Black Sea. Production fell sharply, limiting supplies of CPC Blend crude at a time when European and Asian refiners were already looking beyond the Gulf.
This overlap is especially important. The oil market can usually absorb a regional disruption by purchasing more crude from another region. When Middle Eastern, Red Sea and Black Sea routes are affected simultaneously, replacement barrels become more expensive and difficult to obtain.
North Sea and West African grades have consequently attracted stronger demand. However, these regions cannot immediately expand production enough to replace every lost or delayed cargo. Production capacity, export terminals, tanker availability and refinery compatibility all impose practical limitations.
High Prices Could Destroy Demand but Damage the Economy
Demand destruction remains one of the market’s final balancing mechanisms. Higher fuel prices encourage households to drive less, airlines to reduce capacity, factories to cut output and businesses to postpone energy-intensive activity.
The IEA estimated that global oil demand experienced a sharp year-on-year decline during the second quarter of 2026 as the conflict disrupted supply and raised prices. China’s reduced buying also relieved pressure on the international market.
However, demand destruction is not a harmless solution. It balances the oil market by weakening economic activity. Persistently expensive energy can raise transportation and manufacturing costs, increase inflation and reduce consumer spending.
The market may therefore find equilibrium only through economic pain. That possibility is why the current phase is more dangerous than an ordinary oil price rally. The remaining constraint may no longer be additional supply, reserves or rerouting capacity. It may be the point at which consumers and businesses can no longer afford the prevailing price.
The Market Now Depends on De-Escalation
The global oil system has demonstrated remarkable flexibility. Strategic reserves, lower Chinese demand, alternative pipelines, higher American exports and adaptable refineries prevented an unprecedented disruption from becoming an immediate global shortage.
Those tools have limits. Inventories have been drawn down, shipping routes are threatened in multiple regions, insurance costs are elevated and physical crude premiums are rising. The IEA has warned that its expectation of a future market surplus depends on recovering tanker traffic and a lasting reduction in hostilities.
Without meaningful de-escalation, the market may struggle to repeat the adjustments that contained the earlier crisis. The next supply loss would strike a system with fewer reserves, more expensive transportation and reduced flexibility.
The dangerous new phase is therefore not defined only by oil trading above $100. It is defined by the gradual exhaustion of the mechanisms that kept prices from moving much higher.
