Why the Strait of Hormuz Matters

The Strait of Hormuz connects the Persian Gulf with global markets and carries roughly one‑fifth of the world’s oil trade, making it one of the most critical energy chokepoints on the planet.

Even without a formal blockade, heavy military activity, tanker attacks, or insurance restrictions can dramatically reduce shipping traffic. When flows fall, global supply tightens quickly because exporters such as Saudi Arabia, Iraq, and the United Arab Emirates depend heavily on this route to ship crude.

UBS argues that as long as traffic through the strait remains restricted, the "path of least resistance" for oil prices is upward because markets must price in both actual supply losses and the possibility of deeper disruptions.

How a Supply Shock Could Push Oil Toward $150

Analysts emphasize that the most extreme price forecasts reflect stress scenarios, not base cases. Still, UBS and other market watchers warn that a prolonged disruption could push Brent prices sharply higher.

In a worst‑case scenario where Hormuz exports remain heavily constrained for an extended period, several forces could combine to drive a spike:

• Large export losses: If tanker flows remain restricted, a major portion of Gulf crude exports could temporarily disappear from the market.
• Production shut‑ins: Conflict and logistical constraints can force producers in the region to curtail output.
• Replacement scramble: Importers would compete for alternative supplies from other producers, driving prices higher.

Under those conditions, analysts warn Brent could briefly overshoot above $150 per barrel as markets reprice the severity of the supply shock.

Inventories and Stockpile Drawdowns

Global oil markets typically rely on inventories to cushion sudden supply disruptions. But when supply losses persist, those buffers can shrink quickly.

Commercial inventories and government reserves become critical during shocks because they can temporarily replace lost production. However, rapid inventory drawdowns often push prices higher, as traders bid up crude to encourage additional supply and ration demand.

Concern over these dynamics has already pushed policymakers and analysts to consider emergency measures.

How Other Institutions Are Responding

UBS is not alone in revising its outlook. Major banks and energy agencies have also adjusted forecasts as the conflict has intensified.

Goldman Sachs

Goldman Sachs has raised its near‑term oil forecasts as supply risks increase. The bank lifted its Q2 Brent forecast by $10 and WTI by $9, and estimates that prices could rise by roughly another $15 per barrel if the Strait of Hormuz remains closed for a full month.

In separate scenario analysis, Goldman has suggested Brent could briefly reach around $110 per barrel if flows through the strait were cut in half for a month and remain partially disrupted afterward.

HSBC

HSBC has also adopted a more bullish outlook. The bank raised its 2026 average Brent forecast to about $95 per barrel, assuming a longer period of restricted traffic through the strait and a gradual recovery in Gulf production and shipping later in the year.

Barclays and broader market reaction

Other institutions are moving in the same direction. Barclays increased its 2026 Brent forecast to around $100 per barrel, warning that the longer disruptions last, the larger and more persistent the price shock becomes.

International Energy Agency (IEA)

The International Energy Agency has focused on stabilizing supply rather than issuing aggressive price forecasts.

In response to the crisis, IEA member countries agreed to release about 400 million barrels of oil from emergency reserves, the largest coordinated stock release in the agency’s history, to offset supply losses and calm markets.

These reserves are designed specifically for events like a major supply disruption in the Strait of Hormuz.

The Key Divide: Base Case vs. Tail Risk

Across banks and energy agencies, there is broad agreement on one point: geopolitical risk has fundamentally changed the oil market outlook.

Where analysts differ is in how severe the disruption will be.

• Base cases assume shipping gradually resumes and Gulf production stabilizes.
• Stress scenarios assume prolonged disruptions, large export losses, and deeper inventory drawdowns — conditions that could send prices toward or even above $150 per barrel.

For now, the global oil market is balancing between those two possibilities. The trajectory of tanker traffic through the Strait of Hormuz — and the duration of the conflict surrounding it — will likely determine which scenario ultimately plays out.
