Goldman Sachs Maintains Q4 Oil Price at $90, Cuts 2027 Forecast to $80

Overview

This Goldman Sachs oil analyst report updates global oil price forecasts against the backdrop of the Strait of Hormuz disruption. The core conclusion is that although supply disruptions have lasted longer than previously expected, weaker-than-expected demand (particularly from China and petrochemical feedstocks) and increased non-Middle East supply have resulted in a Q2 2026 market deficit far smaller than the initially feared 14-15 mb/d. Consequently, Goldman Sachs maintains its Q4 2026 Brent oil price forecast at $90/bbl. Looking ahead to 2027, driven by increased production following the UAE's exit from OPEC, supply growth in the Americas, and permanent demand loss due to China's accelerated shift to EVs, Goldman Sachs cuts its 2027 average Brent price forecast by $5 to $80/bbl. Despite a projected record surplus of 3.5 mb/d in 2027, low starting inventory levels, strategic reserve rebuilding, and security premiums will keep oil prices resilient.

Core views

Demand Side: Global oil demand destruction is estimated at approximately 4-5 mb/d, with about half stemming from petrochemical feedstock demand. China's crude import demand fell nearly 4 mb/d YoY, a key driver of the price pullback. The report expects petrochemical demand to fully recover due to destocking in the chemical supply chain rather than reduced end-consumption; however, over 10% of weak demand is expected to persist into 2027 as China accelerates its transition to alternatives like EVs. The share of EV sales in China's passenger vehicle market rose from 50% in February to 62% in May. Supply Side: Middle East liquids output was impacted by 14-15 mb/d, but the actual Q2 deficit was only 5-6 mb/d due to factors including: nearly 5 mb/d of demand loss, a pre-war projected surplus of nearly 3 mb/d, and a 1.5 mb/d upward revision in global ex-Middle East production. Gulf producer exports are expected to normalize by end-August (previously end-June), requiring Hormuz flows to recover to 70% of pre-war levels, supplemented by redirections via alternative routes such as Yanbu, Fujairah, the Gulf of Oman, and Ceyhan. 2027 supply growth mainly comes from: UAE production rising to 4.1 mb/d post-OPEC exit (+0.5 mb/d vs. Feb forecast), Brazil (+0.26), Venezuela (+0.27), Guyana (+0.15), and the US. The global surplus in 2027 is projected to reach 3.5 mb/d. Price Mechanism: The Q4 2026 Brent forecast is maintained at $90/bbl, nearly $30 above pre-war projections, comprising a $19 spot price uplift (due to sharp declines in Middle East output and commercial inventories) and a $9 forward price uplift (as markets reprice capacity disruption risks). The 2027 average price is $80/bbl, $10 above the 2025 average despite a record surplus, because: 1) OECD commercial inventories start low, with strategic reserve rebuilding absorbing 1.1 mb/d; 2) Security premiums provide a price floor.

Analysis framework

Goldman Sachs employs a 'Supply-Demand Balance + Scenario Analysis' methodological framework. First, by dissecting the transmission mechanism of the Middle East supply shock, it decomposes the 14-15 mb/d production loss into offsetting factors such as demand destruction, non-Middle East supply increases, and pre-war surpluses to derive the actual market deficit. Second, by tracking physical constraints on alternative routes for Hormuz flows (Yanbu Pipeline, ADCOP Pipeline, Ceyhan Pipeline, etc.), it assesses the timeline for supply recovery. Third, comparing historical cases (Libya 2011, Russia-Ukraine 2022, Financial Crisis 2008) to analyze differences in the speed and persistence of demand recovery—demand typically recovers quickly after supply shocks, while weakness following economic recessions is more persistent. Fourth, validating assumptions through prediction market pricing. Finally, constructing three scenarios (Adverse, Severely Adverse, Benign) for sensitivity analysis to quantify price paths under different supply recovery paces.

Methodology notes

• Industry/Sector Analysis FrameworkSupply-demand framework

  The core analytical paradigm for oil markets is tracking supply-demand gaps (deficit/surplus) and their impact on inventories and prices

  Goldman Sachs decomposed the 14-15 mb/d supply loss from the Hormuz disruption layer by layer through channels such as demand destruction, non-Middle East supply increases, and pre-war surpluses, ultimately deriving an actual Q2 deficit of 5-6 mb/d. This approach helps explain why a massive supply shock did not translate into a price spike of equal magnitude.

• Cycle & Sentiment FrameworkInventory cycle (Kitchin)

  OECD commercial inventories are the key variable linking supply-demand gaps to spot prices

  The report identifies inventory levels as the core driver of spot vs. forward prices. Significant destocking in 2026 leaves a very low starting point for 2027 inventories; even with a 3.5 mb/d surplus, inventories are unlikely to accumulate rapidly to high levels, thereby supporting spot prices.

• Event Arbitrage & Behavioral FinanceExpectation Gap/Management

  Investor position adjustments are a significant driver of financial price movements

  The report notes that Brent futures fell 25% from March highs, partly because investor long/short ratios declined amid 'ceasefire' expectations, indicating that expectation revisions in financial markets have an independent impact on short-term prices.

• Industry/Sector Analysis FrameworkSubstitution Effect Analysis

  Energy substitution effects are accelerated during crises, potentially making some demand loss permanent

  The report specifically highlights the rise in China's EV penetration from 50% to 62%, arguing that the Hormuz shock accelerated the transition from oil to alternative energy. Approximately 10% of demand destruction is expected to be persistent, representing a significant revision to the traditional 'demand elasticity recovery' assumption.

Impact & implications

The report argues that despite facing a record 3.5 mb/d surplus in 2027, oil prices will remain resilient at an average of $80/bbl, $10 above the 2025 average. Key supports for this view include: low starting inventory levels making it difficult for OECD commercial stocks to reach highs in 2027, and global strategic reserve rebuilding (especially in China and non-OECD countries) absorbing significant excess supply. Furthermore, post-Hormuz repricing of supply disruption risks will create a persistent security premium. Under scenario analysis, if Gulf export normalization is delayed until October, the Q4 2026 average Brent price could rise above $110; if Hormuz remains largely closed throughout the year, the 2027 average could reach $140. Conversely, if recovery occurs early by end-July and demand losses prove more persistent, Q4 2026 could average just $70 and 2027 just $60.

Risks

• Strait of Hormuz disruption lasts longer than expected, with geopolitical uncertainty surrounding supply recovery
• China and global oil demand recovery may be slower than expected, especially with accelerating EV substitution
• Actual production increase by UAE post-OPEC exit may exceed forecasts
• Global strategic reserve rebuilding progress may fall short due to fiscal or policy factors
• Uncertainty regarding the extent of petrochemical feedstock demand recovery

What to watch

• Progress of Strait of Hormuz flow recovery and utilization of alternative routes (Yanbu, Fujairah, Gulf of Oman, Ceyhan)
• Changes in China's crude import demand and EV penetration rates
• Drilling activity and production restart preparations in Saudi Arabia, Iraq, and other nations
• Actual changes in OECD commercial inventories and strategic reserves
• Pricing shifts in prediction markets regarding supply recovery timelines
