Brent prices in only a moderate risk premium, but the physical market has tightened significantly due to supply disruptions in multiple regions

Overview

The report assesses the global oil market by tracking inventories, shipping, exports, imports, and refinery runs. Although the U.S. canceled its attack on Iran and gave negotiations a “last chance,” causing Brent to retreat to the low-to-mid $80s per barrel, the market still faces elevated uncertainty around Middle East supply. Goldman Sachs believes current prices include only a moderate risk premium, while the recent rapid decline in global visible inventories shows that physical supply and demand have tightened significantly.

Core views

The report’s core view is that oil prices are being pulled in the short term by two forces: diplomatic easing limits the geopolitical risk premium, while lower Persian Gulf and Red Sea flows, disruptions to Russian and CPC exports, and stronger Asian imports support physical prices. In the base case, Brent remains at $80–90/bbl before confirmation of a new U.S.-Iran agreement or a significant escalation in the scope of attacks. The supply tightening is not a single-region event, but the combined result of Middle East transport disruptions, lower Russian exports, and Asian restocking.

Analysis framework

The report combines OECD commercial inventories, current OECD demand, the long-term Brent price anchor, and the historical relationship between inventories and spot prices relative to forward prices to estimate fair value; it also uses 7-day, 14-day, and 28-day moving averages of shipping, loadings, imports, exports, inventories, and refinery data to identify short-term supply-demand changes, comparing them against pre-war, normal, year-on-year, and week-on-week benchmarks.

Methodology notes

• Valuation methodsInventory-price fair value framework

  Estimate Brent spot fair value based on inventory levels and the long-term price anchor

  The model combines OECD commercial inventories, OECD demand, the long-term Brent anchor price, and the historical relationship between inventories and spot prices relative to forward prices to estimate Brent spot fair value at about $80/bbl.

• High-frequency supply-demand trackingGlobal visible inventory counter

  Measure physical market tightness through observable inventory changes

  Global visible inventories fell at a pace of 6.3mb/d over the past two weeks, indicating that reduced supply flows and stronger Asian imports are rapidly drawing down visible inventories.

• Logistics and trade flowsShipping flow moving-average tracking

  Use 7-day, 14-day, and 28-day moving averages to reduce noise in high-frequency shipping data

  The report separately tracks trade flows in the Persian Gulf, Red Sea, Russia, CPC, and Asia, and combines them with voyage lags to assess when export changes transmit to imports and inventories.

• Scenario analysisGeopolitical conflict dual-trigger scenario

  Use a diplomatic agreement or military escalation as conditions for oil prices to break out of the range

  The base case expects Brent to remain at $80–90/bbl; a new U.S.-Iran agreement could depress the risk premium, while a significant escalation in the scale or targets of attacks could push prices above the upper end of the range.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Brent crude oil

  Directly affected by global inventories, Persian Gulf supply, and the geopolitical risk premium

  Strengths

  Rapid decline in global visible inventories, disruptions to Russian and CPC exports, and stronger Asian imports.

  Weaknesses

  Current prices are near or above fair value, and diplomatic easing could compress the risk premium.

  Comparison

  Spot fair value is about $80/bbl, with a short-term assumed range of $80–90/bbl; 36-month fair value is $76/bbl.

  Risks

  Outcome of U.S.-Iran negotiations, expansion of attack targets, and the pace of recovery in Hormuz and Red Sea shipping.

• Brent prompt spread

  Inventory drawdowns and tight spot supply typically strengthen prompt prices relative to deferred prices

  Strengths

  A 6.3mb/d inventory drawdown and lower exports from multiple regions support prompt tightness.

  Weaknesses

  The current time spread already embeds some expectations of supply-demand tightness, and data revisions could weaken the signal.

  Comparison

  The report estimates the 1-month versus 36-month spread at about 7% and 14% under different demand assumptions.

  Risks

  Rapid supply recovery, a pullback in Asian imports, or upward revisions to floating inventory data.

• Saudi crude exports

  Red Sea route disruptions force exports to be rerouted via Egypt’s SUMED pipeline

  Strengths

  Flows to Ain Sukhna are increasing, and SUMED still has slightly more than 1.5mb/d of remaining rerouting capacity.

  Weaknesses

  Flows through the Bab-el-Mandeb Strait, Yanbu, and Red Sea shipping routes have fallen significantly, and rerouting capacity cannot fully offset the shock.

  Comparison

  Saudi exports via Bab-el-Mandeb fell by 1.6mb/d week-on-week, while oil flows to Ain Sukhna increased by 1.0mb/d.

  Risks

  Deterioration in Red Sea security, SUMED capacity constraints, and port loading disruptions.

• Russian and CPC crude oil

  Attacks on tankers, refineries, and Black Sea terminals directly reduce exports and related production

  Strengths

  Reduced supply provides support for global crude prices.

  Weaknesses

  Russian crude and condensate exports have fallen, and CPC loadings remain well below normal levels.

  Comparison

  Russian crude and condensate exports fell by 1.3mb/d over two weeks, while the CPC loading shortfall is about 1.0mb/d.

  Risks

  Duration of attacks, terminal recovery progress, and further production cuts at Kazakhstan’s Tengiz oil field.

• China refining and refined product market

  Higher Chinese imports support global crude demand, but export policy and run rates limit refined product supply to overseas markets

  Strengths

  China contributed 2.3mb/d of the increase in Asian net crude and condensate imports.

  Weaknesses

  Refinery run rates have declined slightly, while inventory security requirements and export quotas limit the expansion of refined product exports.

  Comparison

  China’s net refined product exports increased by 0.8mb/d year-on-year, but full-year export quotas are expected to be broadly flat versus last year.

  Risks

  Fading effects of earlier low-price purchases, changes in domestic demand, and adjustments to policy-driven inventory requirements.

Key data

• Brent spot fair valueAbout $80/bblEstimated based on OECD inventories, demand, the long-term price anchor, and the historical inventory-price relationship.
• Brent short-term assumed range$80–90/bblApplies to the base case in which a U.S.-Iran agreement has not yet been confirmed and military conflict has not escalated significantly.
• 36-month Brent fair value$76/bblThe corresponding 36-month market price is about $70/bbl; the long-term assumption includes a $9/bbl structural security premium.
• Change in global visible inventories-6.3mb/dThe pace of inventory decline over the past two weeks.
• Persian Gulf oil flows9mb/d, about 36% of pre-war levels7-day moving average; in the first half of July it was close to 80% of pre-war levels.
• Estimated Persian Gulf flow loss15.3mb/dThe report’s estimate of the current shock to Persian Gulf oil flows.
• Red Sea main-route flowsDown 1.7mb/d week-on-weekCombined flows through the Bab-el-Mandeb Strait and Suez Canal, using a 7-day moving average.
• Saudi flows via Ain SukhnaUp 1.0mb/d over the past weekShows that Saudi Arabia is using Egypt’s SUMED pipeline to strengthen rerouted shipments.
• Remaining SUMED rerouting capacitySlightly above 1.5mb/dAssumes total capacity of 2.5mb/d and compares it with flows in the first half of 2026.
• Russian crude and condensate exportsDown 1.3mb/d over the past two weeksThe report believes this is related to late-June drone attacks shifting from refineries to tankers.
• CPC loading shortfallAbout 1.0mb/d below normal levels7-day moving average; attacks in the Black Sea have repeatedly disrupted loadings.
• Asian net imports of crude and condensateUp 5.6mb/d over the past two weeks14-day moving average, of which China contributed 2.3mb/d.
• China net refined product exportsUp 0.8mb/d year-on-yearThe report believes export quotas, energy security requirements, and lower refinery run rates will limit further substantial growth.

Impact & implications

Recent data support Brent spot prices and prompt spreads: multiple supply chains are disrupted simultaneously, while Asian imports are absorbing previously high loadings and driving inventory drawdowns. However, the fair value estimate of about $80/bbl indicates that current prices are already slightly above the value implied by pure inventory fundamentals, so further upside depends more on conflict escalation or persistent supply losses. If the U.S. and Iran reach an agreement and Red Sea and Persian Gulf flows recover, the risk premium could fall quickly; if attacks expand and suppress tanker, port, or pipeline operations, the current moderate risk premium may be insufficient to reflect tail risks.

Risks

• If the U.S. and Iran reach a new agreement, lower Persian Gulf supply risk could quickly compress the Brent risk premium.
• If attacks expand to more tankers, ports, pipelines, or critical energy facilities, actual supply losses could be significantly higher than currently priced.
• Alternative routes such as SUMED can cushion Red Sea disruptions, but remaining capacity is limited and cannot fully replace disrupted flows.
• Part of the increase in Asian imports stems from earlier low-price purchases and three-to-four-week shipping lags, and may later fall back.
• Shipping and floating inventory data are noisy, and revisions to data from Kpler and others could change the scale of inventory drawdowns.
• Changes in China’s export quotas, energy security policy, and refinery run rates could alter the regional refined product balance.

What to watch

• Whether U.S.-Iran negotiations and management arrangements for the Strait of Hormuz result in a formal agreement.
• Whether Brent can break above or below the $80–90/bbl base-case range.
• Whether Persian Gulf flows can continue to recover from 36% of pre-war levels.
• Flows and rerouting capacity through the Bab-el-Mandeb Strait, Suez Canal, Yanbu, and SUMED.
• Progress in the recovery of exports after attacks on Russian tankers, refineries, and CPC Black Sea terminals.
• Whether the decline in global visible inventories continues, and whether floating inventory data are revised upward again.
• Whether import growth in Asia, especially China, can continue.
• China’s refinery run rates, refined product export quotas, and inventory policy.
