Oil Prices in the Driving Seat as Energy Shock Upends Global Markets

As the Strait of Hormuz remains choked and tankers burn in the Persian Gulf, the oil market is no longer pricing in a geopolitical skirmish. It is pricing in a civilisational disruption.

The spigot that controls 20% of the world’s daily oil trade is now a weapon of war — and the global economy is only beginning to absorb the consequences. When U.S. and Israeli forces launched Operation Epic Fury on February 28, 2026, targeting Iranian leadership and military infrastructure, energy markets registered a tremor. In the fortnight since, that tremor has become a seismic event. Brent crude closed above $103 per barrel on March 13, its highest sustained level since Russia invaded Ukraine in 2022, while WTI has breached $98. The International Energy Agency has declared this the largest supply disruption in the history of the global oil market. Wall Street banks are revising their models with unusual haste — and unusual alarm. The oil prices Iran war 2026 shock is no longer hypothetical. It is underway, accelerating, and may not have found its ceiling.

The Hormuz Reality: How the Strait of Hormuz Oil Shock Is Rewriting Global Supply

A Chokepoint Becomes a Combat Zone

The Strait of Hormuz, a 33-kilometre-wide waterway separating Oman and Iran, is the single most consequential piece of maritime real estate on Earth. Before the war, roughly 20 million barrels per day of crude and refined products — nearly one-fifth of global daily consumption — transited its waters each morning. Today, that flow has collapsed to a trickle. Tankers are refusing passage after Iranian forces attacked multiple vessels; the U.K.’s Maritime Trade Operations logged at least six ship strikes in 48 hours last week alone.

With crude and oil product flows through the Strait of Hormuz plunging from around 20 mb/d before the war to a trickle currently, and limited capacity available to bypass the crucial waterway, Gulf countries have cut total oil production by at least 10 mb/d. IEA The knock-on is brutal: Iraq’s three main southern oilfields have seen production fall 70%, from 4.3 million bpd to just 1.3 million bpd CNBC, while the UAE has begun carefully managing offshore output as onshore storage reaches capacity.

The IEA’s Unprecedented Intervention — and Why It Isn’t Working

In a historic acknowledgement of the crisis’s severity, the IEA convened an emergency collective action: more than 30 nations across Europe, North America and Northeast Asia agreed to release 400 million barrels of oil from strategic stockpiles — the largest action in the agency’s 50-year history — led by a U.S. release of 172 million barrels from its Strategic Petroleum Reserve. CNBC

The markets responded with cold indifference. Crude prices surged more than 17% since the IEA announced the emergency stockpile release. The U.S. will release 172 million barrels over 120 days, implying 1.4 million barrels per day — just 15% of the supply lost due to the Hormuz closure. CNBC

As Tamas Varga of oil broker PVM put it with disarming clarity: “Until transit is reactivated, those kinds of policy announcements are going to have limited impact.” The 400 million barrels would be entirely absorbed in just 26 days at current supply loss rates. The oil bazooka has misfired.

Wall Street’s Bank-by-Bank Warnings on the Iran War Energy Crisis

Goldman Sachs: Extending the Disruption Timeline

Goldman Sachs raised its Brent and WTI crude oil price forecasts for Q4 2026, now assuming 21 days of severely reduced Strait of Hormuz flows — at just 10% of normal levels — followed by a 30-day gradual recovery. Previously, the bank had modelled only a 10-day disruption. BOE Report

Goldman projects prices will average above $100 per barrel in March, $85 per barrel in April, and roughly $70 per barrel later in the year — almost 20% higher than early 2026 levels on average. The Mirror The bank has also explicitly flagged that the oil prices Iran war 2026 shock makes a June Federal Reserve rate cut very difficult to justify, given mounting inflationary pressures. Fewer rate cuts, sustained higher energy costs, stagflationary drag: the macro implications extend well beyond the crude curve.

In an upside risk scenario modelled by Goldman, if Hormuz flows remain severely constrained for additional weeks, Brent could reach $150 per barrel before the end of Q1 — a level not seen since the speculative blowout of 2008.

Barclays: “Investors Are Growing Nervous by the Day”

Barclays’ macro research team has offered some of the most candid assessments. In a note last Friday, Barclays’ Emmanuel Cau warned that investors were becoming increasingly jittery after initially pricing in a short-lived conflict, noting that “the longer the Strait of Hormuz stays closed the more stagflationary markets will turn.” CNBC Barclays has modelled Brent crude testing $120 in a fleshed-out conflict scenario, with a high-end case of $150 before month-end if disruption persists.

Rystad Energy: Scenarios to $135 by June

Consulting firm Rystad Energy has published a scenario matrix that has become something of a benchmark for energy desks globally. Rystad forecasts a two-month war will push Brent to $110 per barrel by April, while a four-month conflict could spike Brent to $135 per barrel by June. CNBC Critically, the firm notes that oil prices could rise to demand-destruction levels before the IEA stockpile release meaningfully reaches the market.

RBC, Deutsche Bank, and the Stagflationary Warning

Deutsche Bank’s head of global macro research Jim Reid wrote that “from a market perspective, the problem is that investors are increasingly pricing in a more protracted conflict that causes extensive economic damage.” CNN RBC Capital Markets, alongside Barclays and Bloomberg, had earlier identified a plausible scenario in which a sustained Hormuz blockade results in triple-digit oil — a scenario that has now materialised.

Key Bank Forecasts at a Glance:

• Goldman Sachs: Brent averaging $98/bbl in March–April; $71/bbl Q4 base case; $150 upside tail risk
• Barclays: $120 near-term; $150 extreme scenario
• Rystad Energy: $110 (2-month war) → $135 (4-month war)
• Bernstein: IEA action will have “limited impact on the trajectory of oil prices”
• ExxonMobil (Tyler Goodspeed, Chief Economist): Probability distribution skewed toward “harder and longer” Hormuz closure

Global Ripple Effects: Inflation, Stocks, and the Developing World

How Iran War Affects Gasoline Prices in 2026

The pump has become the most visceral political battleground. In just the first week after the strikes on Iran, the average price of gasoline in the United States increased 48 cents per gallon. Center for American Progress According to the AAA motor club, the average price of gas hit nearly $3.60 a gallon on March 12, a jump of nearly 35 cents in a week. Time In California, drivers are paying $5.34 per gallon; San Francisco’s Shell stations have logged $6.50. Diesel — the lifeblood of supply chains, trucking and agriculture — has surged 28% since hostilities began, to $4.83 per gallon nationally.

The inflationary arithmetic is unforgiving. One in three dollars of fertiliser cost globally originates in the Gulf. Urea prices have already risen by 35% since February 28. Gulf states produce nearly 49% of global urea exports and 30% of global ammonia exports, with around one-third of the world’s urea transiting the Strait of Hormuz. Time

European Natural Gas: A 75% Surge

Europe’s exposure has been severe. Europe’s benchmark natural gas rose 75% since the war began, as Iran-linked disruptions cut off around 20% of global LNG exports, threatening heating costs and industrial competitiveness across the continent. PBS With memories of the 2022 Russian gas crisis still raw in Brussels and Berlin, the political mood is approaching pre-crisis emergency.

The Global South: Energy Shock as Existential Crisis

For wealthy economies, $100 oil is painful. For the developing world, it may be catastrophic.

Djibouti’s finance minister warned that the fighting would “bring severe economic consequences for developing countries,” with small maritime states at risk of “being pulled into deeper economic uncertainty.” Egypt’s President Abdel Fattah el-Sisi declared his country’s economy in a “state of near-emergency.” Al Jazeera

At least 85 countries have reported increases in petrol prices following the February 28 attacks. Cambodia recorded the highest increase — nearly 68% — while Vietnam saw a 50% rise, Nigeria 35%, and Laos 33%. Japan and South Korea, importing 95% and 70% of their oil from the Gulf respectively, have enacted emergency measures. Al Jazeera Bangladesh closed universities and enacted fuel restrictions; Pakistan implemented a four-day government workweek.

Historical Parallels: 1973, 2008, Russia-Ukraine — and Why This Is Different

Every analyst worth their Bloomberg terminal is reaching for historical comparisons. The parallels are instructive — but also dangerously incomplete.

• 1973 Arab oil embargo: A politically motivated supply cut of roughly 4-5 million bpd produced a 400% price spike and a global recession. The current disruption is already 10 million bpd — more than twice the scale.
• 2008 oil shock: Demand-driven, peaked at $147/bbl, collapsed within months. The current shock is supply-driven and geopolitically sustained, with no demand-destruction valve yet triggered.
• Russia-Ukraine 2022: The fear of losing Russian supply sent Brent to $127. Russia’s exports were ultimately rerouted; there is no rerouting Hormuz. As Wood Mackenzie’s Alan Gelder observed, the parallels are instructive but imperfect: the current disruption involves physical closure of the world’s most critical chokepoint — not sanctions circumvention.

The CEO of British energy firm EnQuest told CNBC that the oil market has “never seen something of this magnitude before.” CNBC He is not given to hyperbole. The IEA’s own language — “the largest supply disruption in the history of the global oil market” — is itself unprecedented.

Scenarios: The Path to $150 Brent — or Resolution

Scenario 1: The Short War (2–4 weeks, Brent $95–$110)

Iran’s new Supreme Leader Mojtaba Khamenei capitulates under military pressure; Hormuz reopens within 30 days. Strategic reserves cover the gap; inflation spikes prove transitory. The most optimistic scenario markets have partially priced in. Requires: credible ceasefire, rapid escort operations, infrastructure intact enough to resume exports.

Scenario 2: The Prolonged Conflict (2–4 months, Brent crude $135–$150 forecast Iran)

Iran’s new supreme leader has vowed to keep the Strait of Hormuz closed as a “tool of pressure,” with continued attacks on commercial vessels deepening the disruption. CNBC Production shut-ins spread from Iraq and Kuwait to the UAE and Saudi Arabia. Strategic reserves are depleted. Global GDP contracts by 1.5–2 percentage points. This is Goldman’s upside risk scenario and Barclays’ high-end case.

Scenario 3: Infrastructure Annihilation (4+ months, $200+)

Iranian military spokesman Ebrahim Zolfaqari issued a blunt warning: “Get ready for oil to be $200 a barrel, because the oil price depends on regional security, which you have destabilised.” CNBC If major Gulf energy infrastructure — Saudi Aramco’s Ras Tanura, Qatar’s LNG facilities, UAE offshore platforms — sustains serious damage, the recovery timeline extends to years, not months. This remains a tail risk, but it is no longer an unthinkable one.

Policy Implications: OPEC+, the SPR, and the Energy Transition

What OPEC+ Can and Cannot Do

Gulf Arab states are cutting production not by strategic choice but because they are running out of storage space, as crude piles up with nowhere to go due to the closure of the Strait. CNBC OPEC+ announced a modest output increase of 206,000 bpd at the war’s outset — a rounding error relative to the 10+ million bpd supply loss. Saudi Arabia is exploring rerouting crude to the Red Sea via overland pipeline, but this covers at most 2 million bpd of its 6.5 million bpd export capacity.

The SPR Dilemma

The U.S. entered this crisis with a Strategic Petroleum Reserve that, by bipartisan consensus, was inadequately stocked. The Trump administration neglected to refill the nation’s Strategic Petroleum Reserve ahead of the war, leaving the economy further exposed to supply shocks. Center for American Progress The 172 million barrels now being released represent 41% of total U.S. SPR holdings — a significant depletion of the last-resort buffer for a crisis that shows no sign of swift resolution.

The Energy Transition Paradox

There is a bitter irony in this crisis for energy transition advocates. High oil prices structurally accelerate the shift to EVs, heat pumps and renewable energy — as demonstrated post-2022. But they simultaneously devastate the fiscal capacity of developing nations needed to finance that transition. The energy crisis Iran conflict could simultaneously hasten clean energy adoption in wealthy economies while locking the Global South into fossil fuel dependency for another decade.

The Road Ahead: Strategic Questions for Governments and Investors

We are now in the third week of the most consequential energy disruption since the 1970s, and the fundamental question has not changed: when, and under what conditions, does the Strait of Hormuz reopen?

As analysed in our earlier piece on Hormuz’s geopolitical history, the strait has been threatened but never functionally closed in the modern era. That precedent has now been broken. The market is being forced to price the unpriced: a sustained, militarily enforced closure of the world’s most critical oil chokepoint, with a belligerent actor who has explicitly stated its intent to keep it shut.

For investors, the calculus is clear: energy equities and commodities remain the hedge of first and last resort. For governments — particularly in Asia, Africa and South Asia — the imperative is emergency demand management, accelerated reserve releases, and diplomatic pressure on Washington to define an exit strategy. For central banks, stagflation is no longer a theoretical risk; it is appearing on the yield curve.

President Trump has described the rise in oil prices as “a very small price to pay” for destroying Iran’s nuclear capability. Markets, at $103 per barrel and rising, are beginning to question the arithmetic. The oil tap that powers 20% of the world’s trade has become a geopolitical spigot — and no one, including the superpower that turned it, appears certain how to turn it back on.

The global markets energy shock from the Strait of Hormuz is not just an energy story. It is a macroeconomic, geopolitical, and humanitarian inflection point — one whose full consequences will be measured not in barrels, but in years.
