The Middle East Conflict: Oil, Trade Routes, and Systemic Risk

Why This Matters Now

The Middle East in 2026 is experiencing its most complex and multi-layered security environment since the 1973 Arab-Israeli War. The Israel-Hamas conflict that began in October 2023 has expanded into a regional dynamic involving Hezbollah in Lebanon, Houthi forces in Yemen, Iranian proxy networks in Iraq and Syria, and periodic direct confrontation between Israel and Iran. Each escalation step carries the potential to disrupt one or more of the critical energy chokepoints that connect Persian Gulf production to global markets.

The scale of energy infrastructure at risk is staggering. The Persian Gulf region contains approximately 48% of global proved oil reserves and 38% of global proved natural gas reserves. Saudi Arabia, Iraq, Iran, the UAE, Kuwait, and Qatar collectively produce approximately 31 million barrels per day of crude oil and condensate, representing roughly 30% of global supply. This production reaches global markets through two primary maritime chokepoints: the Strait of Hormuz at the mouth of the Persian Gulf and the Bab el-Mandeb strait at the southern entrance to the Red Sea. The disruption of either chokepoint, let alone both simultaneously, would create energy market dislocation without historical precedent.

The International Energy Agency's 2025 Oil Market Report identified Middle East geopolitical risk as the single largest upside threat to oil prices, estimating that a Hormuz disruption scenario could add $50 to $80 per barrel to benchmark crude prices within days. The US Energy Information Administration's 2025 Annual Energy Outlook modeled a "severe disruption" scenario in which loss of 4 million barrels per day of Gulf transit capacity for 90 days would push Brent crude above $180 per barrel and reduce global GDP by 1.2% over 12 months. These institutional assessments, while useful, may understate tail risk because they assume rational de-escalation within weeks, an assumption that the current multi-actor, multi-theater conflict dynamic does not support.

The Strait of Hormuz: The World's Most Critical Chokepoint

The Strait of Hormuz is a narrow waterway between Iran and Oman connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. At its narrowest point, the strait is 21 nautical miles wide, with shipping lanes of only 2 miles in each direction separated by a 2-mile buffer zone. Approximately 21 million barrels per day of crude oil and condensate transit the strait, along with approximately 4 billion cubic feet per day of LNG from Qatar, representing the single largest concentration of energy flows through any geographic chokepoint globally.

Iran's military capability to disrupt Hormuz transit is substantial and multi-layered. The Islamic Revolutionary Guard Corps Navy operates approximately 1,500 fast attack boats, many armed with anti-ship missiles, capable of executing swarm tactics against commercial vessels. Iran's shore-based anti-ship missile inventory includes the Noor (a Chinese C-802 derivative with 120 km range), the Ghader (200 km range), and the Khalij-e-Fars (300 km anti-ship ballistic missile), all of which can reach vessels anywhere in the strait from concealed mobile launchers. Iran's submarine force, including three Kilo-class diesel-electric submarines and approximately 20 midget submarines, can deploy naval mines or conduct torpedo attacks in the shallow waters of the strait.

The critical distinction in Hormuz risk analysis is between disruption and closure. A full, sustained closure would require Iran to establish and maintain sea denial across the entire strait width against US Fifth Fleet response, which would include carrier strike group operations, mine countermeasures, and air superiority. This is militarily demanding and would invite devastating US retaliation against Iranian naval and military infrastructure. However, selective disruption, demonstrating the capability to damage or destroy individual vessels through mines, missiles, or fast attack boat raids, achieves much of the economic impact without requiring sustained military confrontation. The insurance and shipping industry response to demonstrated risk can be nearly as disruptive as physical closure.

During the 1987 to 1988 Tanker War, Iranian attacks on commercial shipping in the Persian Gulf caused marine insurance premiums to increase tenfold, reduced tanker traffic through the strait by approximately 25%, and contributed to a $5 to $10 per barrel risk premium on Gulf-origin crude. Modern insurance markets would respond even more dramatically because the interconnected nature of global reinsurance means that war risk premium increases propagate through the entire marine insurance ecosystem within days.

Red Sea and Bab el-Mandeb: The Second Chokepoint

The Bab el-Mandeb strait, connecting the Red Sea to the Gulf of Aden, is 18 miles wide at its narrowest point and handles approximately 8.8 million barrels per day of crude oil and petroleum products, primarily northbound flows from the Persian Gulf to Europe and southbound flows from Russia and the Caspian region. The strait also handles approximately 12% of global container trade and significant LNG volumes transiting from Qatar to European terminals.

Since November 2023, Houthi forces in Yemen have conducted sustained attacks on commercial shipping transiting the Red Sea and Bab el-Mandeb, using a combination of anti-ship ballistic missiles, cruise missiles, naval drones, and unmanned surface vessels. As of Q1 2026, over 120 attacks have been conducted, damaging or sinking multiple commercial vessels and forcing approximately 60 to 70% of container shipping to reroute around the Cape of Good Hope. This rerouting adds 10 to 14 days to Europe-bound voyages from Asia and increases per-voyage fuel and operating costs by $1 million to $1.5 million.

The economic impact of Red Sea disruption extends far beyond direct shipping costs. The rerouting has added an estimated $15 to $20 billion in annual shipping costs globally, contributed to a 3 to 5% increase in container freight rates on Asia-to-Europe routes, and added $3 to $8 per barrel in risk premium to oil cargoes transiting the region. The Suez Canal Authority reported a 45% decline in transit revenue in 2024, reducing Egypt's foreign currency earnings by approximately $4 billion annually, a significant fiscal blow to an economy already under IMF program conditionality.

The strategic significance of the Houthi campaign extends beyond its immediate economic impact. It has demonstrated that a relatively low-capability non-state actor can impose meaningful costs on global trade through a sustained campaign of maritime harassment. The military response, including US and UK airstrikes against Houthi positions and a multinational naval escort operation (Operation Prosperity Guardian), has degraded but not eliminated the threat. This creates a precedent: if Houthi forces can sustain disruption against Western naval forces, the deterrence value of naval power in protecting maritime chokepoints is diminished, potentially encouraging similar tactics by other actors in other regions.

Gulf State Fiscal Dynamics Under Extreme Prices

The assumption that all Persian Gulf oil producers benefit uniformly from higher oil prices is incorrect. Each country's fiscal position depends on its breakeven oil price, the price per barrel required for the government budget to balance. Countries with breakeven prices below the market price accumulate fiscal surpluses and sovereign wealth fund contributions. Countries with breakeven prices above the market price run deficits that deplete reserves and may require spending cuts or debt issuance.

As of the IMF's 2025 Regional Economic Outlook, fiscal breakeven oil prices varied significantly across Gulf states. The UAE's breakeven was approximately $60 per barrel, reflecting aggressive economic diversification through tourism, logistics, and financial services. Kuwait's breakeven was approximately $55, supported by a relatively small population and large sovereign wealth fund. Saudi Arabia's breakeven was approximately $96, reflecting the ambitious spending requirements of the Vision 2030 diversification program including NEOM, the Entertainment Authority, and expanded social spending. Iraq's breakeven was approximately $105, the highest among major Gulf producers, reflecting large public sector employment, reconstruction costs, and a growing population with high youth unemployment.

At $150 to $200 oil, all Gulf producers would be in significant fiscal surplus, generating revenues far exceeding their breakeven prices. Saudi Arabia at $150 oil would generate approximately $90 billion in annual surplus above its breakeven requirement. At $200 oil, the surplus would approach $170 billion. The UAE at $200 oil would generate surpluses exceeding $80 billion. These surpluses would flow into sovereign wealth funds, with the Abu Dhabi Investment Authority, the Saudi Public Investment Fund, and the Kuwait Investment Authority collectively deploying hundreds of billions in additional capital into global markets.

However, fiscal surplus does not equal political stability. Saudi Arabia's domestic social contract depends on sustained government spending on employment, housing, education, and subsidies. If oil revenues spike but conflict risk threatens future production, the political calculus becomes complex: should the government increase spending to maintain social stability, or should it save the windfall to insure against future disruption? Historical evidence suggests Gulf governments tend to increase spending during price booms, creating ratchet effects that raise future breakeven prices and increase vulnerability to subsequent price declines.

The Iran-Saudi-Israel Escalation Ladder

The three-way geopolitical dynamic between Iran, Saudi Arabia, and Israel determines the probability distribution of Middle East conflict scenarios that would affect energy markets. Each bilateral relationship carries distinct escalation risks that interact in complex and sometimes counterintuitive ways.

The Iran-Israel dynamic has shifted from covert competition to open confrontation since April 2024, when Iran launched approximately 300 missiles and drones at Israel in direct retaliation for the Israeli strike on the Iranian consulate in Damascus. Israel's subsequent retaliatory strikes against Iranian air defense systems established a precedent of direct military exchange between the two countries. The escalation ladder from this baseline extends through several rungs: targeted strikes against nuclear facilities, attacks on energy infrastructure, naval confrontation in the Persian Gulf, and ultimately broader regional conflict drawing in proxy forces and potentially requiring US military intervention.

The Iran-Saudi relationship has experienced a diplomatic thaw since the China-brokered rapprochement in March 2023, with both countries reopening embassies and resuming diplomatic communication. However, the underlying security competition remains: Iran's proxy network including Hezbollah, the Houthis, and Iraqi Shia militias continues to operate, and Saudi Arabia's dependence on US security guarantees creates structural tension with Iran's anti-Western strategic orientation. A significant escalation in the Iran-Israel conflict would strain the Saudi-Iranian rapprochement, potentially forcing Saudi Arabia to choose between its relationship with Washington and its diplomatic opening with Tehran.

The risk of deliberate or accidental attacks on oil infrastructure is the most direct transmission channel from political escalation to energy market impact. The 2019 Abqaiq and Khurais attacks demonstrated that precision-guided drones and cruise missiles can target specific processing facilities with high accuracy. Saudi Aramco's oil processing infrastructure is concentrated in a relatively small number of high-value facilities: Abqaiq processes approximately 7 million barrels per day, Ras Tanura is the world's largest offshore oil loading facility, and the East-West Pipeline connects Gulf production to Red Sea export terminals. A coordinated attack on two or three of these facilities could remove 5 to 10 million barrels per day from global supply for weeks or months, depending on damage severity and repair capability.

Insurance Market Transmission

Marine insurance is the invisible infrastructure of global trade, and its pricing dynamics amplify the economic impact of conflict far beyond the immediate zone of hostilities. The marine insurance market operates through a layered structure: primary insurers underwrite hull and machinery policies, protection and indemnity clubs cover third-party liability and crew, and war risk insurers cover losses from military action, terrorism, piracy, and civil unrest. All three layers are interconnected through reinsurance treaties that spread risk across the global insurance market.

War risk insurance premiums are the most sensitive to conflict escalation. Before the Houthi attacks escalated in late 2023, war risk premiums for Red Sea transit were approximately 0.05% of vessel value, a nominal charge reflecting low perceived risk. By Q1 2024, premiums had increased to 0.5 to 0.7% of vessel value, and by Q1 2026, they had stabilized at 0.7 to 1.0% for vessels continuing to transit the Red Sea. For a vessel valued at $100 million, this represents a per-transit cost increase from $50,000 to $700,000 to $1,000,000.

A Hormuz disruption would trigger insurance premium increases of an entirely different magnitude. The Lloyd's Market Association's Joint War Committee, which designates listed areas where war risk insurance is required, would likely designate the entire Persian Gulf as a high-risk zone. Historical precedent from the 1987 to 1988 Tanker War suggests that war risk premiums for Persian Gulf transit could increase to 3 to 5% of vessel value, representing $3 million to $5 million per transit for a laden VLCC (Very Large Crude Carrier) valued at $100 million. These costs would be passed through to oil purchasers within days, adding $2 to $4 per barrel to the delivered cost of Gulf crude before any supply disruption premium.

The insurance market also creates a self-fulfilling disruption dynamic. When premiums increase beyond certain thresholds, shipping companies calculate that the cost of insurance exceeds the potential profit from the voyage, and voluntarily reroute or refuse to transit. This reduces effective supply without any physical blockade. The Houthi campaign has demonstrated this dynamic: the majority of the 60 to 70% traffic reduction through the Red Sea is voluntary rerouting driven by insurance costs and crew safety concerns, not physical inability to transit.

Petrodollar Recycling and Dollar Hegemony

The petrodollar system, established through informal agreements between the United States and Saudi Arabia in the 1970s, ensures that global oil transactions are denominated and settled in US dollars. This creates structural demand for dollars and dollar-denominated assets, supports the dollar's reserve currency status, and provides the United States with the ability to leverage financial sanctions as a foreign policy tool. Petrodollar recycling, the process by which oil-exporting countries reinvest their dollar-denominated oil revenues into US Treasury securities, real estate, and financial assets, provides a significant source of demand for US government debt.

An oil shock pushing crude to $150 to $200 would generate enormous petrodollar flows. At $200 oil, OPEC's 13 member countries would collectively earn approximately $4.5 trillion in annual oil revenue, compared to approximately $1.2 trillion at $60 oil. The recycling of these revenues back into dollar-denominated assets would support the dollar and US Treasury prices during a period when the US government would simultaneously be facing pressure to increase spending on strategic petroleum reserve refilling, military operations, and domestic energy subsidies.

However, the petrodollar system faces structural challenges that an oil crisis could accelerate. China, now the world's largest oil importer, has been negotiating yuan-denominated oil purchase agreements with Saudi Arabia, the UAE, and Iran since 2022. The Shanghai International Energy Exchange's yuan-denominated oil futures contract has grown from negligible volume to approximately 15% of Brent-equivalent trading volume. Russia's oil exports to China and India are increasingly settled in yuan and rupees rather than dollars. These bilateral arrangements currently represent a small fraction of total oil trade, but a crisis that disrupts SWIFT-based dollar settlement or creates political pressure to bypass US financial infrastructure could accelerate the shift.

Escalation Scenario Modeling

The range of possible conflict outcomes in the Middle East can be modeled along an escalation ladder with distinct energy market implications at each rung. The baseline scenario, continuation of the current pattern of proxy conflict, Houthi maritime harassment, and periodic Israel-Iran tensions, maintains the $3 to $8 per barrel risk premium already embedded in current prices. This scenario does not push oil to $150 but sustains elevated prices in the $80 to $100 range.

A moderate escalation scenario involving a significant Israel-Iran military exchange targeting nuclear or military facilities but not oil infrastructure would likely push oil prices to $100 to $130 temporarily, driven by fear premium rather than actual supply disruption. This scenario assumes that both sides exercise restraint in targeting energy infrastructure due to mutual vulnerability, with Iran dependent on oil export revenues and Israel dependent on imported energy.

A severe escalation scenario involving deliberate targeting of Gulf oil infrastructure, whether through Iranian missiles, proxy drone attacks, or retaliatory strikes against Iranian export terminals, would push oil prices to $150 to $200 depending on the volume of production disabled and the estimated repair timeline. The Abqaiq precedent suggests that a well-targeted attack on processing infrastructure can remove 5 to 7 million barrels per day for two to four weeks. A coordinated multi-target attack could extend the disruption to months.

The extreme scenario, a Strait of Hormuz closure or contested zone lasting more than 30 days, would push oil prices above $200 and potentially into uncharted territory. This scenario would simultaneously disrupt oil, LNG, and containerized trade, creating cascading economic impacts across energy, manufacturing, and food supply chains. The probability assigned to this scenario by geopolitical risk consultancies ranges from 5 to 15%, a low probability but catastrophic impact event that justifies serious institutional planning and hedging.
