How Middle East Supply Risks Are Growing in Impact on Global Oil Trading

The area is responsible for about one-third of the world’s crude production. That should make it significant in and of itself. What makes matters worse is that export infrastructure is concentrated in a handful of terminals, pipelines, and maritime corridors where a disproportionately large share of oil is exported. The disruption of any of them (even for a moment) reduces a large supply signal to an extremely short time frame.

The issue of the supply is something that generally doesn’t get the same kind of attention it should get, but the clearest example of this recurring issue is Libya. In recent years, internal political squabbles about how to divide up oil revenues have led to several production shutdowns that have temporarily increased the tightness of the light sweet crude grades refined by European and Asian plants. The disruptions are likely to persist when there is no political agreement, and the pattern is robust. In recent years, Iraq’s export pipeline to the North through Turkey has also been down for extended periods of time. These relatively inconspicuous disruptions can add up and impact medium-term supply dynamics, though not necessarily have the same impact as a more conspicuous incident.

The Middle East is a geopolitical risk that has many variables. It’s a combination of interwoven pressures that work in various ways and to varying effects on the length of the price impact. The issues that currently have the greatest attention of serious analysts are generally of three types:

• Export infrastructure and production infrastructure are currently under physical threat to production.
• Sanctions regimes and the dynamics of their enforcement.
• Disruption of shipping routes and attendant disruption of the trade economics.

Everything is unique, and sometimes they are not in the same direction at the same time. That’s part of what makes the current situation more complicated than any one risk headline implies.

The latest example of large-scale infrastructure targeting is the 2019 attack on Saudi Aramco’s Abqaiq and Khurais facilities in the country, which was carried out using drones and missiles. The loss in output occurred temporarily, amounting to about 5.7 million bpd, the largest sudden supply shock in modern oil market history. The recovery was quicker than many expected, partly because of the operational robustness of Aramco and partly because the situation was swiftly contained diplomatically. But the event has permanently changed the way markets view the vulnerability of infrastructure in the Gulf, and that repricing has not been complete.

Iran’s petroleum sales have also been sustained in the face of sanctions, largely via Asian markets out of reach to Western sanctions. A full-fledged deal between Tehran and Western governments has yet to be hammered out, as of early 2026. That has left volumes of Iranian supply in a limbo of sorts: they could be rapidly reduced by stepped-up enforcement, and they could be dramatically increased by a change in diplomatic circumstances. Both of these results can have significant price consequences, and even the uncertainty can be a factor in the market without a clear decision.

The concentration levels in Saudi Arabia’s export system warrant a more significant focus than is generally found outside of export specialist circles. Abqaiq processes and stabilizes a huge percentage of Saudi crude before it is shipped to export terminals, removing the sulfur from it. That kind of ‘single point of failure’ is not typical in most industrial supply chains. In the case of oil, it’s a structural aspect of the market and one that has been proven, not just thought.

However, OPEC+ compliance has been quite lackluster at times, notably from Iraq and Kazakhstan, which have had a history of overproduction. This gives rise to an everlasting discrepancy between OPEC+ declarations and the actual supply data. For analysts, the bottom line is that it is important not to take production decisions at face value but to also consider the track record of implementation once a deal has been agreed on to see what the real supply impact was.

Since late 2023, the Houthis have started to attack commercial shipping vessels in the Red Sea more frequently, and these attacks have persisted through 2025. What those disruptions drove home is that it’s not necessary to blow a wellhead to impact oil market economics. A round-the-Cape voyage will increase the time in transit by about ten to fourteen days, as well as the fuel costs. During periods of increased Houthi activity, insurance costs for tankers traveling in the Gulf area skyrocketed. Both impacts are not a direct factor in the crude benchmarks, but both impact the effective landed cost of Middle East barrels in destination markets.

Knowing the difference is important, as geopolitical events do not affect oil prices in a single manner. Some effects are immediate and visible: a surge in the price of Brent futures within minutes of an incident report. Others come more slowly, via changes in freight rates, changes in the repricing of insurance, and changes in buyer behavior, which may take days or weeks to be reflected in trade flow data. The rate of these impacts varies, and so do their effects.

Then there is the issue of what the market “already” had in place whether there was an event or not. When there is a constant regional tension, there is usually some risk premium in prices. The incremental market move may therefore be less than anticipated when an event then reinforces concerns, the surprise element of the event, which is typically the one that produces the biggest market moves, is already discounted.

The following table shows some of the more significant supply events that took place in the Middle East and the approximate market impact. The trend of most entries was that the first price movement has been greater than the actual physical supply effect, at times much greater, and then it has partially retraced to a more stable situation.

Crude oil benchmarks are not the only place where supply risk from the Middle East exists. It extends out to related markets in ways that are not always apparent when the world’s focus is on the Brent or WTI headline price.

The second-order victim is likely to be refined product markets. In times of crude supply shortages or increased uncertainty, refinery margins and regional product availability may be affected to a greater extent, and the effects on end consumers may be magnified, especially in regions where there is little local refining or a high concentration of import logistics. The energy crisis of 2022 in Europe was a prime example of how the upstream pressure to supply energy flows through the downstream more quickly than most market players would have thought.

Other segments of the market that are impacted by increased supply risks in the Middle East are:

• Tanker freight rates, which can also rise sharply without reference to crude prices during times of major-scale rerouting.
• In oil-dependent economies, currency markets can be affected by changes in the prices of the oil that the state supplies, which change expectations of fiscal revenue and sovereign credit risk.
• LNG markets with some short-term fuel switching demand in the exposed economies as a result of regional geopolitical pressure.
• In agricultural commodity markets, where there is known overlap between energy input costs and food production, processing, and transport economics

During the IEA’s coordinated strategic reserve release in 2022, it was seen that policy tools are in place to mitigate short-term supply shocks and that they can be implemented on a material scale when political conditions are right. However, there are drawbacks to those processes. During that time, reservoir levels were lowered significantly, and a rebuild takes time. There are also doubts about the effectiveness as a deterrent because, over time, markets will factor in the possibility of a release during the next big disruption event, effectively canceling the effect of a release in advance.

It’s easy to fall into the temptation, because of the amounts of money potentially involved, of viewing geopolitical risk analysis as a predictive tool. It generally lacks it there. It’s actually helpful for comprehending markets and its actions, as well as for charting structural weaknesses that are price-relevant. What it doesn’t do well is tell you when an event will happen, or how big the market’s reaction will be when it does.

Instead of getting lost in qualifications, the specific limitations should be called out:

• Escalation and de-escalation are non-linear and unpredictable to a great extent. Conflict situations that appear to be intractable can be solved in a flash, and stable times can fall apart in an instant. Both directions remain silent and don’t herald themselves.
• When demand for a commodity is the same, the market price may be quite different in the two market conditions. There are interactions between the geopolitical trigger and positioning, sentiment and open interest that are not modelable in advance.
• Secondary effects (such as freight repricing, product supply shifts and insurance cost changes) happen at varying rates to the initial crude price move, and thus the total impact of the market is more difficult to gauge in real time.
• Analytical path dependency can occur when geopolitical narratives set up a framework that later information gets filtered through, without being recognized as such.

All this does not negate the analysis. It’s about calibration and about honesty when the power of explanation runs out, and speculation sets in.

Middle East supply risk is not a succession of shocks that will come and go and be completely addressed but rather a structural state in global oil markets. The combination of production weight, geographic concentration of export infrastructure, and political complexity of the region always comes with a certain level of supply uncertainty as a base case. The level of that uncertainty and the extent to which that uncertainty is priced into securities on a given day are what change.

The hard part for traders, analysts, and energy investors is not recognizing that there is risk – that’s obvious. It’s gaining a good enough sense of what matters most at a given moment, what the big picture supply-demand dynamics are, and at what point a careful study of the facts begins to look like well-informed guesswork. The clear understanding of that boundary is, in fact, probably more valuable than any single analytical framework that can be applied to the boundary.
