April 27, 2026 — Goldman Sachs’ Commodities Research team released its latest oil market report, raising its Q4 2026 Brent crude price forecast from $80 to $90 per barrel, a 12.5% increase. At the same time, the WTI crude forecast rose from $75 to $83, with 2027 Brent and WTI projections also revised up to $85 and $80 per barrel, respectively. The report further raised this quarter’s (Q2 2026) Brent average price forecast to $100, and Q3 to $93, marking a systematic revaluation of the annual oil price curve.
The primary driver behind this upward revision is the "extreme inventory drawdown" triggered by the prolonged closure of the Strait of Hormuz. Goldman analysts Daan Struyven and Yulia Zhestkova Grigsby explicitly warn in the report that "extreme inventory depletion is unsustainable." If the supply shock persists, the market may be forced into even deeper demand destruction.
As of April 27, Gate market data shows Brent crude (XBR) trading at $101.40, up 1.04% over 24 hours, with an intraday range of $99.71 to $101.93. WTI crude (XTI) stands at $96.45, up 1.12% on the day, ranging from $94.62 to $97.07. Both major benchmarks are rising in tandem, directly reflecting Goldman’s upgraded forecasts and the ongoing deadlock in US-Iran negotiations.
From Escalating Conflict to Strait Blockade
The current wave of extreme international oil price volatility can be traced back to February 28, 2026, when the US and Israel launched joint military strikes against Iran. The conflict quickly escalated from airstrikes to maritime confrontations. Over the following two months, the status of the Strait of Hormuz repeatedly shifted, forming a clear yet turbulent timeline.
Late February to March: Following the US-Israel joint strikes, Iran responded by imposing a blockade on the Strait of Hormuz as its core countermeasure. This vital waterway, responsible for about one-fifth of global oil shipments, saw daily transit volumes plummet to near zero. Major Gulf oil producers—Saudi Arabia, Iraq, Kuwait, and the UAE—faced the dual pressures of blocked export routes and nearly full domestic storage, forcing them to slash output or even halt production. According to the International Energy Agency (IEA), global oil supply losses in March alone exceeded 360 million barrels.
Mid-April (April 17–18): A brief diplomatic window opened over the Strait of Hormuz. On April 17, Iranian Foreign Minister Araghchi announced that, given the Lebanon-Israel ceasefire, Iran would reopen the Strait to all commercial shipping. US President Trump confirmed this on social media. However, Iran imposed three conditions: only commercial vessels could pass, ships must use Iran-designated routes, and passage required Iranian military approval. The US, meanwhile, made clear that its own maritime blockade against Iran would remain fully in effect.
April 18: Within 24 hours, the situation deteriorated sharply. Iran’s Armed Forces Central Command accused the US of "repeatedly breaking promises" and using the blockade as a pretext for "maritime piracy," declaring the Strait under renewed military control. The Islamic Revolutionary Guard Corps warned that all vessels in the Persian Gulf and Gulf of Oman were to remain at anchor, and any approach to the Strait would be treated as hostile, with violators at risk of attack.
April 24–27: Diplomatic efforts hit a major setback. Iranian Foreign Minister Araghchi visited Pakistan and Oman, then flew to Moscow on April 27 for talks with President Putin. On the US side, President Trump canceled Special Envoy Whitkopf and son-in-law Kushner’s planned trip to Pakistan and Iran, citing "travel time, excessive costs," and "serious confusion within Iran’s leadership." In a Fox News interview on April 26, Trump signaled that "Iran can call to negotiate," but Iran firmly denied any talks were scheduled.
At this point, geopolitical deadlock and the Strait’s blockade became mutually reinforcing—lack of progress in peace talks prolonged the blockade, while the blockade itself became the central bargaining chip at the negotiating table.
Data & Structural Analysis: Quantifying the Supply-Demand Imbalance
Goldman’s forecast revision is not a knee-jerk reaction but is grounded in a rigorous supply-demand balance model. The report structurally dissects the price impact of the Hormuz shock, allowing for a clear assessment of each contributing factor.
Supply Gap: Over 10 Million Barrels Lost Daily
Goldman’s report presents striking baseline data: In April, Persian Gulf crude output losses reached 14.5 million barrels per day. Compared to a pre-war forecast of 26.4 million barrels per day, actual output now stands at just 11.9 million barrels per day. The report cross-validated this scale using three independent methods:
- Inventory Method: Global visible inventories fell by an average of 5.8 million barrels per day in April, with estimated "hidden" inventories (mainly non-OECD refined products) dropping 6.2 million barrels per day, totaling about 12 million barrels per day.
- Supply-Demand Method (Hormuz Flows): Tracking strait and pipeline flows to estimate export demand, the April supply-demand gap is calculated at 11.3 million barrels per day.
- Supply-Demand Method (Country Balances): Global production at 9.02 million barrels per day versus demand at 10.16 million barrels per day, again yielding a gap of 11.3 million barrels per day.
The global oil market has swung from a daily surplus of 1.8 million barrels in 2025 to a historic Q2 2026 shortfall of 9.6 million barrels per day. OECD commercial inventories alone are projected to fall by 2.2 million barrels per day this quarter.
Price Structure Breakdown: The Source of the $30 Jump
Goldman’s upgrade of its Q4 Brent forecast from $80 to $90 per barrel reflects a nearly $30 systematic revaluation (relative to pre-Hormuz shock levels):
| Driver | Quantitative Impact | Core Logic |
|---|---|---|
| Massive Commercial Inventory Draw | ~$18/bbl | Lower inventories drive spot premiums over futures, directly lifting spot prices |
| Long-Term Security Premium Repricing | ~$9/bbl | Permanent loss of 500,000 bpd Persian Gulf capacity prompts risk reassessment of spare capacity concentrated in the region |
| Q4 Absolute Forecast Adjustment | $80→$90/bbl | Net result of the above, plus delayed normalization of exports until late June |
The report further notes that, prior to the shock, global spare capacity was about 3.7 million barrels per day. For every 1 million bpd reduction in effective spare capacity, long-term prices rise by roughly $4. Goldman estimates that, after accounting for sanctioned oil releases, strategic reserve draws and replenishments, demand declines, and increased US and Russian production, the Hormuz shock will result in a net reduction of 1.236 billion barrels in global commercial oil inventories by Q4 2026.
Demand-Side Contraction
The flip side of the supply shock is forced demand contraction. Goldman projects that, due to soaring refined product prices, global oil demand will fall by 1.7 million barrels per day year-over-year in Q2 2026, and by 100,000 barrels per day for the full year. The largest downward revisions are in the Middle East (directly affected by supply disruptions), South Korea and Japan (petrochemical hubs facing feedstock shortages), and price-sensitive regions in Africa. The IEA offers an even more pessimistic view, flipping its 2026 global oil demand forecast from a 730,000 bpd increase to an 80,000 bpd contraction—a single-month downward revision of 810,000 bpd.
Notably, the current demand decline is not simply "price-driven demand destruction." JPMorgan strategist Natasha Kaneva points out that even with Brent futures averaging below $100, global demand dropped by 2.8 million bpd in March and a further 4.3 million bpd in April—outpacing the steepest declines seen during the 2009 financial crisis. This suggests much of the "demand decline" is actually demand being choked off by lack of supply: consumers aren’t unwilling to pay for oil—they simply can’t get it.
Structural Tension Between Data and Price Signals
A key paradox emerges: Brent spot prices peaked in March but have fallen back in late April, with current futures prices below the March highs. Market optimism about a swift reopening of the Strait temporarily suppressed risk premiums and triggered "front-running" inventory drawdowns. Goldman emphasizes that this gap between optimistic expectations and actual supply conditions is the market’s biggest risk. In other words, prices have not fully reflected the true extent of supply-demand deterioration. Once optimism fades and reality takes over, there is significant room for further price repricing.
Sentiment Analysis: Divergence and Consensus Among Major Institutions
On the outlook for oil prices and supply-demand fundamentals, major global energy research organizations and investment banks are sharply divided. The following breakdown highlights the core logic behind each institution’s methodology.
Goldman Sachs: Inventory-Centric, Bullish Baseline
In Goldman’s latest report, inventories serve as the central analytical anchor. The logic is clear: Persian Gulf output loss → record-fast global inventory depletion → spot price premiums → long-term security premium repricing → upward shift in the price curve. The report’s core risk warning is that "extreme inventory depletion is unsustainable," meaning prices will keep rising until demand is forced lower—a necessary path to market equilibrium. Goldman stresses that economic risks are greater than its baseline scenario suggests: "There is net upside risk to oil prices, abnormally high refined product prices, risk of product shortages, and the unprecedented scale of this shock."
Morgan Stanley: More Optimistic Start, Same End Point
Morgan Stanley maintains its forecasts for Brent at $110 in Q2, $100 in Q3, and $90 in Q4. Its calculations show the Hormuz blockade has cut Gulf output by 14.2 million bpd, with global inventories falling by 4.8 million bpd daily. While Morgan Stanley estimates a slower inventory draw than Goldman, its Q4 target matches Goldman’s revised forecast—reflecting broad agreement on the "tight mid-term supply-demand balance" thesis.
JPMorgan: Supply-Demand Math Doesn’t Add Up, Prices Must Go Higher
JPMorgan takes the most aggressive stance. Strategist Natasha Kaneva bluntly states, "Oil prices need to go much higher." The core logic: when spare capacity can’t fill the gap and inventories are running dry, only much higher prices can curb consumption and balance the market. The report notes that observable inventories were drawn down by 4 million bpd in March and accelerated to 7.1 million bpd in April, yet the gap persists. The real danger, it argues, is that not all inventories are visible—especially refined product stocks, which are less transparent. The true drawdown may exceed reported data. This aligns closely with Goldman’s "hidden inventory" thesis.
IEA & EIA: From Surplus to Extreme Shortage
The IEA’s monthly report sketches a dramatic reversal: before the conflict, 2026 was expected to see a global supply surplus of nearly 4 million bpd—a record annual excess. After the conflict, March global oil supply plunged by 10.1 million bpd to 97 million bpd, the largest single-month drop on record, removing nearly 250 million barrels from the market. The EIA projects global oil inventories will fall by 5.1 million bpd in Q2 2026, with Brent potentially peaking at $115. The IEA, EIA, and OPEC have all revised their Q1 2026 inventory forecasts downward by over 2.6–3 million bpd.
Nature of the Core Disagreements: Methods and Assumptions
Overall, market disagreements over the oil price outlook center on two dimensions: first, when the Strait of Hormuz will reopen—Goldman’s baseline assumes late June, while some market participants expect an earlier resolution; second, the true price transmission coefficient of inventory depletion—JPMorgan argues that prices are still far from equilibrium, while Goldman offers a more quantified estimate using its inventory-term structure-spot premium framework. However, all parties agree on one key point: with the current supply-demand gap, upside price risk far outweighs downside risk.
Industry Impact Analysis: Transmission Mechanisms and Structural Shocks Across the Energy Value Chain
Upstream: Price Upside and Delays in Supply Recovery
For upstream oil and gas producers, the Hormuz shock’s biggest structural impact is the loss of global spare capacity as a buffer. Remaining spare capacity is now highly concentrated in Saudi Arabia and the UAE, but with Persian Gulf export routes blocked, this capacity is virtually inaccessible to world markets. Meanwhile, meaningful increases in US shale output typically require 3–6 months, with only 300,000–700,000 bpd available in the short term. Russia has about 300,000 bpd of idle capacity, but ongoing infrastructure attacks make near-term increases difficult. All supply-side correction mechanisms have effectively failed at once, leaving the market reliant on inventory drawdowns and demand contraction. According to a Ping An Securities report, even if the conflict gradually subsides, the mid-term price floor for upstream oil and gas has shifted higher—likely above $80 per barrel, making a return to the pre-conflict $60/bbl surplus era unlikely.
Midstream Refining: Exceptionally High Refined Product Prices
Refined products are the most underestimated risk vector in this crisis. Goldman’s report highlights that the spread between refined product and crude prices is at historic highs. After the conflict began, some Middle Eastern refineries were attacked or forced to cut output, severely disrupting global petrochemical supplies. Many European and Asian chemical producers have slashed refinery runs due to soaring feedstock costs and tight supply, leading to major cutbacks in olefins, PVC, methanol, ethylene glycol, and other products. Singapore middle distillate (diesel, jet fuel) prices briefly topped $290 per barrel, a record high. As of April 27, average US gasoline prices reached $4.10 per gallon (up 37% from pre-war levels), and diesel hit $5.46 per gallon (up 45%). This means consumer price pressure is far greater than crude futures would suggest.
Downstream and the Real Economy: Depth and Breadth of Demand Restructuring
The petrochemical sector is undergoing a top-down cost shock. In March, the oil and chemical industry prosperity index rose 2.49 points to 99.09, but internal divergence is clear—upstream oil and gas extraction and fuel processing saw improved cost-profit margins, while mid- and downstream manufacturing suffered from surging input costs and weak end-user demand, pulling their indices lower. About 15% of China’s natural gas imports come from Qatar; the Hormuz blockade has caused large-scale LNG supply disruptions, and the cost impact of alternative sources will likely emerge in Q2 and Q3.
Global Economic Inflation Transmission
The IEA’s April 15 report, in addition to a more pessimistic demand outlook, underscores the systemic pressure of oil price shocks on the global economy. Since the conflict began, Brent has surged nearly 50%. High oil prices are suppressing economic growth and driving up global inflation. In the current macroeconomic climate, persistently high energy costs will constrain central bank policy, trade balances, and consumer spending worldwide.
Conclusion
Goldman’s systematic upward revision of its Brent crude forecast fundamentally reflects the exposure of structural vulnerabilities in the global energy market under extreme stress. When over 10 million barrels per day of supply is removed, global inventories are depleted at record speed, and spare capacity is immobilized by geographic blockades, price becomes not just a reflection of supply and demand—but the final balancing mechanism holding the market together. This supply shock, triggered by the Strait of Hormuz crisis, is profoundly reshaping the logic of energy market pricing.
