Oil Prices Surge 10% Amid Iran Conflict: Could Brent Hit $100 as Strait of Hormuz Closure Looms?

Analysts warn of escalating geopolitical risks driving energy markets into turmoil, with key chokepoint disruptions threatening global supply chains and stoking inflation fears worldwide.

The oil market woke to a seismic jolt this weekend. Within hours of U.S. and Israeli strikes on Iranian military infrastructure, Brent crude surged roughly 10% to approximately $80 a barrel in over-the-counter trading on Sunday — a visceral reminder that in the modern energy economy, geopolitical shockwaves travel faster than any tanker on the high seas. For energy analysts who had spent weeks tracking the slow build of military tension in the Middle East, the price spike was not a surprise. What concerns them far more is what could come next.

“While the military attacks are themselves supportive for oil prices, the key factor here is the closing of the Strait of Hormuz,” said Ajay Parmar, director of energy and refining at ICIS. That single sentence captures the existential anxiety now gripping global energy markets. The Strait of Hormuz — the narrow waterway separating Iran from the Arabian Peninsula — is the single most consequential chokepoint in the world’s oil supply chain, and the possibility of its closure has transformed a market event into a potential global economic crisis.

Real-Time Market Reaction: A Benchmark in Motion

Brent crude had already been climbing before the strikes landed. The global benchmark reached $73 a barrel on Friday — its highest level since July — as traders priced in a growing probability of military confrontation. When futures markets reopen Monday, analysts broadly expect the rally to hold and potentially accelerate.

West Texas Intermediate (WTI), the U.S. benchmark, was trading near $67 a barrel ahead of the weekend, reflecting slightly softer domestic demand signals but tracking the broader geopolitical premium being baked into global crude. The spread between Brent and WTI has widened as Middle Eastern supply-route risk commands a higher premium in internationally traded barrels.

Adding complexity to the supply picture, OPEC+ had only recently agreed to modest output increases of approximately 206,000 barrels per day as part of its phased unwinding of voluntary cuts — a move designed to recapture market share in a period of relative stability. That calculus has now changed overnight. With Iranian production — currently running at roughly 3.2 million barrels per day — suddenly under threat of disruption, and with the group’s Gulf members facing their own strategic calculations, OPEC+’s next emergency meeting could prove pivotal.

The Chokepoint That Could Change Everything

To understand why analysts are invoking $100 oil, one must understand the Strait of Hormuz’s unique position in global energy architecture. According to the U.S. Energy Information Administration, approximately 20 to 21 million barrels of oil pass through the strait daily — representing somewhere between 20% and 30% of all seaborne oil trade globally. Liquefied natural gas flows add another layer of vulnerability: roughly 20% of the world’s LNG supply also transits the strait, with major importers in Asia — Japan, South Korea, China, and India — critically exposed.

Iran has threatened on multiple occasions to close the Strait of Hormuz in response to military pressure. While analysts have historically viewed such threats as largely rhetorical, the current escalation — involving direct U.S. and Israeli strikes on Iranian soil — represents a qualitatively different provocation. Tehran’s calculus on retaliation has shifted. “The risk of even a partial disruption to Hormuz flows is now being priced in ways we haven’t seen since 2019,” one senior energy trader told Bloomberg over the weekend.

Iran possesses a range of asymmetric tools short of an outright blockade: mine-laying, attacks on tanker traffic, and harassment of vessels using its naval assets and proxy forces throughout the region. Any of these actions would trigger insurance market seizures, rerouting costs, and supply delays severe enough to rattle prices without a single barrel being physically withheld.

What Analysts Are Forecasting

The forecasting community has moved rapidly to revise upward its price targets in the wake of Sunday’s developments. The divergence between bull and base cases is wide — reflecting genuine uncertainty about Iran’s response and the duration of any disruption.

Helima Croft, head of global commodity strategy at RBC Capital Markets and one of the most closely watched voices in geopolitical energy analysis, has long warned that Middle East risk was being systematically underpriced by markets. In recent notes, RBC analysts flagged the $90–$95 range as achievable under a moderate disruption scenario, with $100 possible if Hormuz flows are materially curtailed.

Goldman Sachs, whose commodity desk has been tracking the Iran-Israel tension since late 2024, has outlined scenarios in which sustained supply disruption pushes Brent to $95–$100 by Q2 2026 — contingent on whether OPEC+ Gulf members, particularly Saudi Arabia and the UAE, step in with compensatory output.

Rystad Energy’s Jorge León, vice president of oil market research, has previously estimated that a full Strait of Hormuz closure lasting 30 days could remove 15–17 million barrels of daily supply from the market — a shock that dwarfs anything seen since the 1973 Arab oil embargo. Even a partial, weeks-long disruption affecting 30–40% of normal flows could push prices into triple digits.

Capital Economics has taken a more measured line, arguing that OPEC+ spare capacity — estimated at roughly 5–6 million bpd, predominantly held by Saudi Arabia — provides a meaningful buffer. However, their analysts acknowledge that tapping that capacity while simultaneously managing alliance cohesion and navigating U.S. pressure will require careful political choreography.

Global Economic Fallout: From Petrol Pumps to Supply Chains

The consequences of an oil price spike to $100 would reverberate well beyond energy trading floors. Consumer inflation, which central banks in the U.S., EU, and UK have spent two years painstakingly subduing, would face a significant new headwind. Energy costs feed into virtually every sector of the global economy — from petrochemicals and plastics to food production, shipping, and manufacturing.

In the United States, a sustained move to $100 Brent would likely push gasoline prices back above $4 per gallon nationally — a politically toxic level that the Biden and Trump administrations alike have treated as a red line. In Europe, still navigating energy price volatility following the Russia-Ukraine conflict, the impact on household energy bills and industrial competitiveness could be severe.

Emerging market economies face a particularly acute risk. Countries in South and Southeast Asia that import large shares of their energy needs — India, Pakistan, Indonesia, the Philippines — would see their current account deficits worsen sharply, currency pressures intensify, and inflationary spirals become harder to contain. For the world’s most financially vulnerable nations, a prolonged oil shock could tip fragile fiscal positions into crisis.

Global shipping and supply chain disruption extends beyond oil. The Strait of Hormuz is also critical for dry bulk cargo, container traffic, and chemical shipments. Rerouting vessels around the Cape of Good Hope adds weeks to transit times and thousands of dollars per voyage in fuel and operating costs — a friction that cascades through global trade.

Historical Context and the Limits of Alternatives

This is not the first time the world has stared down a Hormuz closure scenario. During the 1980–1988 Iran-Iraq War — the so-called “Tanker War” — over 400 ships were attacked in the Gulf, yet full closure was never achieved, partly because Iran and Iraq both needed oil revenues to fund their war efforts. Tehran today faces a different strategic calculus.

Two pipeline alternatives exist that partially mitigate Hormuz risk. Saudi Arabia’s East-West Pipeline can transport up to approximately 5 million bpd from the Eastern Province to the Red Sea port of Yanbu, bypassing the strait entirely. The UAE’s Abu Dhabi Crude Oil Pipeline can move around 1.5 million bpd to the port of Fujairah on the Gulf of Oman. Together, these routes could offset perhaps 6–7 million bpd — significant, but far short of the 20+ million that currently flows through Hormuz daily.

Conclusion: Between De-Escalation and a Prolonged Crisis

The next 72 hours are likely to be defining. Iran’s formal response to the U.S.-Israeli strikes — whether diplomatic signaling, proportional military retaliation, or an asymmetric escalation campaign targeting Gulf shipping — will determine whether the current oil spike is a spike or the beginning of a sustained re-pricing of global energy risk.

Markets are, at this moment, pricing probability rather than certainty. The $80 Brent level reflects elevated fear; $100 reflects a world in which Hormuz flows are genuinely, materially disrupted. Between those two numbers lies an enormous range of human, diplomatic, and military contingency.

What is not contingent is the underlying vulnerability the current crisis has exposed: a global energy system that, despite years of diversification rhetoric, remains structurally dependent on a waterway 33 kilometers wide at its narrowest point. As Ajay Parmar’s warning makes clear, the military strikes may have lit the match — but the Strait of Hormuz is the powder keg that the world’s economies cannot afford to see ignite.
