Hormuz Reopening Imminent: Goldman Sachs Cuts Oil Price Forecasts

Overview

This report primarily analyzes Goldman Sachs' adjustments to global oil price forecasts following U.S. President Trump's announcement of a temporary agreement to lift the blockade and reopen the Strait of Hormuz, with the signing scheduled for Friday. The core conclusion is that as the Middle East supply recovery timeline accelerates by one month, Goldman Sachs has significantly lowered its Brent and WTI crude price forecasts for Q4 2026 and 2027. The report argues that although the global oil market may face a substantial surplus in 2027, strategic reserve demand and security risk premiums will provide a floor for oil prices.

Core views

Price Forecast Cuts and Supply Recovery Expectations: Goldman Sachs has lowered its Q4 2026 Brent crude forecast from $90/bbl to $80/bbl and its 2027 average forecast from $80/bbl to $75/bbl; WTI forecasts are adjusted accordingly to an average of $75/bbl for Q4 2026 and $70/bbl for 2027. This adjustment is based on the new assumption that oil exports from Persian Gulf nations will return to pre-war levels by end-July 2026 (previously assumed end-August), with production recovering in October. Every one-month acceleration in the supply normalization process is expected to reduce the fair value of crude oil by approximately $10 for Q4 2026 and $5 for 2027. Supply-Demand Fundamentals and Inventory Dynamics: The report notes that despite a projected large supply surplus of 3.2 mb/d in 2027, oil prices will remain resilient, consistent with their long-term fair value assessment of $75/$70. Key reasons include: first, OECD commercial oil inventories are unlikely to reach extreme highs as significant destocking occurred in H1 2026, and global strategic reserve accumulation is expected to exceed 1 mb/d in 2027; second, security premiums arising from geopolitical disruption risks will provide a floor for prices. However, given that the market managed the historically severe 14 mb/d supply shock with remarkable flexibility (particularly regarding China's demand resilience) without sustained extreme pricing, this security premium will also be capped. Two-Way Risk Scenarios: The report emphasizes that risks are two-way, but net risks are skewed to the upside. Upside Risk Scenario: If the Strait of Hormuz remains obstructed throughout 2027, Brent prices could rise above $130 by end-2026 and average $105 in 2027. Downside Risk Scenario: If exports fully normalize by early July, demand losses prove stickier (with peak demand loss of 1.5 mb/d persisting into 2027), and supply from the U.S., Brazil, and UAE strengthens, Brent prices could average below $70 in Q4 2026 and below $60 in 2027.

Analysis framework

Goldman Sachs' analytical logic centers on 'geopolitical event-driven changes in supply expectations.' First, by tracking U.S. presidential policy announcements (lifting the blockade, reopening the strait), the supply recovery timeline is revised (accelerated from August to July). Second, using a supply-demand balance model, the impact of accelerated supply recovery on oil price fair value is quantified (specific price reductions corresponding to each month of acceleration). Finally, combining inventory cycles (OECD commercial inventories bottoming out), strategic reserve trends (structural global restocking), and historical linear relationships between inventory and prices, the report assesses the floor support and ceiling pressure on oil prices amidst a massive supply surplus, thereby presenting a two-way risk scenario analysis.

Methodology notes

• Industry/Sector Analysis FrameworkSupply-demand framework

  Supply-Demand Balance and Inventory Transmission

  Analyzes price trends by evaluating the match between global oil supply (Middle East recovery pace, non-OPEC growth) and demand (China resilience, global economy), combined with inventory changes (OECD commercial stocks, strategic reserves). This is the most core analytical paradigm in commodity research.

• Event Arbitrage & Behavioral Finance

  Geopolitical Risk Premium

  The report mentions a 'security premium' providing floor support for oil prices, representing price compensation demanded by the market due to fears of future supply disruptions. This premium typically rises during geopolitical conflicts and fades when tensions ease or certainty of supply recovery increases.

  Strait of Hormuz Flows and Export Normalization

  The report specifically breaks down flow changes in the Strait of Hormuz (e.g., requiring an increase of 12 mb/d from current levels for full recovery), validating the progress and authenticity of supply recovery by monitoring physical flow data through key chokepoints.

Key data

• Q4 2026 Brent Oil Price Forecast$80/bblPrevious forecast was $90/bbl, cut by $10
• 2027 Average Brent Price Forecast$75/bblPrevious forecast was $80/bbl, cut by $5
• Q4 2026 WTI Oil Price Forecast$75/bblNew forecast
• 2027 Average WTI Price Forecast$70/bblNew forecast
• 2027 Global Oil Supply Surplus3.2 mb/dDespite large surplus, supported by strategic reserve demand
• OECD Commercial Oil Inventory Low2.686 billion bblsExpected to bottom out in July 2026
• Q2 2026 Global Oil Deficit5 mb/dLess than the 14 mb/d shock to Middle East liquids production

Impact & implications

The report suggests that the agreement to reopen the Strait of Hormuz will significantly alleviate market concerns over Middle East supply disruptions, causing oil prices to retreat from geopolitical premiums. For energy market participants, this implies limited short-term upside and significant oversupply pressure in 2027. However, due to structural demand for global strategic reserves and potential geopolitical volatility, oil prices are unlikely to crash to extremely low levels and will instead oscillate around a new supply-demand equilibrium. Investors should monitor the actual implementation of the agreement post-signing and reactions from countries such as Iran.

Risks

• Regional hostilities or attacks on vessels could resume, keeping shipping companies risk-averse and exports/production low
• Clearing potential naval mines could take significant time, hindering transport recovery
• If detailed nuclear negotiations fail, Iran could effectively re-close the Strait of Hormuz after reopening
• Demand losses may be stickier than expected, leading to greater downward price pressure

What to watch

• Planned agreement signing on Friday and specific terms/details
• Whether Persian Gulf exports return to pre-war levels by end-July as scheduled
• Pace of Iranian production recovery amid potential sanctions relief
• Changes in OECD commercial inventories and trends in global strategic reserves
• Actual navigation flows through the Strait of Hormuz and tanker capacity availability
