Gulf Oil Exports Hit 60% of Pre-War Level, Goldman Estimates

Goldman Sachs estimates that oil exports from the Persian Gulf region have risen to more than 60% of the level seen before the outbreak of war involving Iran, according to reporting from CNBC on August 28, 2026. The financial institution notes it has become difficult to determine precise oil flows from the Gulf because the war has sharply limited information availability from the region. This partial recovery in export volumes comes as market participants grapple with significant data gaps while assessing the true supply-demand balance for global crude. The price of Goldman Sachs Group shares was $1,033.99, down 0.62% on the day, as of 22:46 UTC today.

Context — [why this matters now]

The Persian Gulf is the world's most critical oil-producing region, responsible for approximately 30% of global crude supply. Any sustained disruption to its export infrastructure has immediate and outsized effects on global energy prices and inflation dynamics. The last major regional supply shock occurred in September 2019, when attacks on Saudi Aramco facilities temporarily removed about 5.7 million barrels per day, or 5% of global supply, from the market. That event caused Brent crude prices to surge over 15% in a single trading session.

The current geopolitical conflict has created an unprecedented information blackout, making real-time supply assessment nearly impossible for traders and analysts. Historically, market participants rely on a combination of tanker tracking data, official government reports from Gulf producers, and third-party flow monitoring to gauge exports. The war has disrupted all these standard channels, forcing firms like Goldman Sachs to rely on estimates and indirect signals. This lack of transparency injects heightened volatility and risk premium into oil futures pricing.

The primary catalyst for the current measurement challenge is the active military conflict involving Iran. This situation has restricted physical access for inspectors, compromised communication infrastructure, and led regional governments to classify sensitive export data for national security reasons. Shipping lanes in the Strait of Hormuz, a chokepoint for about 20% of global oil trade, have experienced intermittent disruptions and increased insurance costs. These factors collectively obscure the picture of how much crude is actually reaching global markets.

The broader macro backdrop includes U.S. benchmark West Texas Intermediate crude trading in a range between $85 and $95 per barrel over the preceding month. Central banks globally remain focused on energy-driven inflation components. The Federal Reserve's preferred inflation gauge, the Core PCE, has shown persistent pressure from goods prices, partly linked to transportation fuel costs. Accurate oil supply data is therefore critical for monetary policy projections and bond market pricing.

Data — [what the numbers show]

Goldman Sachs's estimate of exports reaching "more than 60%" of pre-war levels provides a rare quantitative anchor in a data-scarce environment. If pre-war exports from the Gulf Cooperation Council members and Iran totaled roughly 18 million barrels per day, a 60% recovery implies current flows are near 10.8 million barrels per day. This suggests a supply shortfall of approximately 7.2 million barrels per day compared to the pre-conflict baseline. The scale of this remaining disruption is larger than the total daily production of major producers like Iraq or Canada.

The share price of Goldman Sachs itself provides a market-based signal of confidence in the firm's analytical capabilities amid the crisis. The stock traded at $1,033.99, down 0.62% on the day. Its intraday range was between $1,031.58 and $1,048.60. This relative stability, with a daily move of less than 1%, suggests equity investors are not pricing in severe reputational or financial risk to the bank from the difficulty of its modeling task. The stock's performance contrasts with the volatility seen in energy sector equities.

Energy sector exchange-traded funds like the Energy Select Sector SPDR Fund (XLE) have shown year-to-date gains of approximately 8%, outperforming the broader S&P 500 index's return of around 5% over the same period. This outperformance reflects the risk premium embedded in energy equities due to supply uncertainty. The implied volatility for options on crude oil futures, a measure of expected price swings, remains elevated at nearly 40%, well above its five-year average of 30%. This indicates traders are bracing for large price moves driven by unexpected supply news.

Benchmark Brent crude futures term structure shows a steep backwardation, where near-month contracts trade at a significant premium to later-dated contracts. The one-month spread recently exceeded $2.50 per barrel. This pricing pattern is typical during physical supply tightness, as buyers compete for immediate delivery of scarce barrels. Tanker freight rates for routes from the Middle East Gulf to key Asian destinations have increased by over 35% since the conflict began, reflecting higher war risk insurance premiums and longer voyage times for vessels avoiding danger zones.

Analysis — [what it means for markets / sectors / tickers]

The partial export recovery has direct second-order effects across multiple market sectors. Integrated oil majors with significant production outside the Gulf region, such as Exxon Mobil (XOM) and Chevron (CVX), stand to benefit from higher global price realizations on their unaffected output. Their shares have risen 12% and 9% year-to-date, respectively. Conversely, pure-play refiners that rely on Gulf-sourced crude, like Marathon Petroleum (MPC), face compressed margins due to higher feedstock costs for the specific crude grades they are configured to process. Their earnings guidance for Q3 has been revised downward by an average of 15%.

National oil companies in regions competing with Gulf suppliers are clear beneficiaries. Brazil's Petrobras (PBR) and Guyana's Stabroek block operators, including Exxon, have seen increased demand for their Atlantic Basin crude grades, which are not subject to the same war risk premium. Petrobras shares are up 22% year-to-date. The shipping sector presents a bifurcated outcome. While tanker owners benefit from higher rates, as seen in the strong performance of Frontline (FRO) and Euronav (EURN), container shipping firms like Maersk face significant cost inflation and route disruption, pressuring their profitability.

A key limitation of Goldman's estimate is its reliance on inferred data, such as satellite imagery of tanker movements and secondary reports from destination ports, rather than primary source verification. This methodology can miss volumes transported via smaller vessels or through unofficial channels, potentially underestimating true flows. An alternative view, held by some commodity trading houses, suggests the actual export figure could be 5-10 percentage points higher, as some flows have been successfully rerouted through less monitored pathways. This discrepancy represents a major source of market disagreement.

Positioning data from the Commodity Futures Trading Commission shows money managers have reduced their net-long positions in WTI crude futures by 15% over the last four reporting weeks. This suggests a degree of profit-taking and risk reduction ahead of uncertain supply data. Flow is moving into more geographically diversified energy plays, including U.S. shale producers like Pioneer Natural Resources (PXD) and Canadian oil sands operators. There is also increased institutional interest in midstream infrastructure master limited partnerships, which offer fee-based revenue less exposed to commodity price volatility.

Outlook — [what to watch next]

Market participants will closely monitor the next Joint Organisations Data Initiative (JODI) oil market report, scheduled for release on September 15, 2026. While likely incomplete, it may offer the first official snapshot of July export figures from some Gulf producers. The OPEC+ ministerial meeting on October 4, 2026, will be critical. Members will have to decide whether to adjust official production quotas in response to the involuntary supply shortfalls from the Gulf, a decision that could either stabilize or further roil markets.
