**Summary**: Goldman Sachs says Persian Gulf exports have quietly climbed back to 15–16 million barrels per day by 08:41 UTC, roughly two-thirds of pre-war levels, with tankers increasingly operating dark and using ship-to-ship transfers. The covert rebound is already pulling oil down toward $89, reshaping wartime energy leverage, enforcement risk, and inflation trajectories.

## Detail

By 08:41 UTC, Goldman Sachs was telling clients that Persian Gulf crude exports have staged a significant wartime comeback, reaching an estimated 15–16 million barrels per day — about two-thirds of pre-war volumes. The recovery is being enabled in part by tankers switching off transponders and relying on ship-to-ship transfers to slip around disruptions and enforcement, a pattern that is already dragging benchmark oil prices down from April’s $120-plus to roughly $89.

Confirmed details from the note indicate this is not a marginal adjustment but a structural rerouting of flows under fire. Volumes at this scale restore a meaningful share of global seaborne supply out of the Gulf despite active naval blockade and sanctions pressure. The data is necessarily model-based, but Goldman’s framing aligns with observed spikes in AIS gaps, high-risk flag usage, and unusual clustering of ship-to-ship activity in known shadow-trading zones.

For real economies, this shift lands directly in household energy bills, freight costs, and food prices. Import-dependent states in Europe, South Asia, and East Africa gain breathing room as fuel and fertilizer input costs ease from panic levels. However, seafarers and local coastal communities face heightened safety and environmental risk as unreported STS transfers, often with under‑insured or poorly maintained vessels, become a core feature of the wartime oil trade.

On the security side, covert routing erodes the transparency on which sanctions enforcement, maritime deconfliction, and naval risk management depend. Dark fleets operating near contested waters increase the odds of miscalculation with blockade forces and raise the probability of unreported spills, collisions, or interdictions gone wrong. The ability of Gulf producers and intermediaries to move this much crude despite declared pressure also weakens the coercive power of current sanctions and blockade regimes.

For markets, the message is that physical tightness is easing faster than many war-scenario models assumed. Brent and WTI face downside pressure in the near term, especially if macro data stays soft, even as a heightened geopolitical risk premium persists. Energy equities could lag broader indices, while fuel-sensitive sectors — airlines, shipping, trucking, and heavy industry — benefit from improved margin outlooks. Gulf sovereigns and shadow intermediaries capture cash flow, but insurers, P&I clubs, and compliance desks inherit rising legal and reputational risk as more barrels move through gray channels.

Over the next 24–48 hours, watch three pressure points: first, whether OPEC+ signals displeasure or hints at deeper cuts to defend price; second, whether US, EU, or allied navies and regulators announce stepped-up monitoring or new secondary sanctions to choke off dark-fleet workarounds; and third, how futures curves respond — any sharp steepening or unwinding of war-risk backwardation will telegraph how seriously traders take this covert but very real supply rebound.

**MARKET IMPACT ASSESSMENT:**
Bearish for crude in the near term as volumes normalize; reinforces pressure on OPEC+ to consider deeper supply management; weighs on energy equities but eases input costs for transport, manufacturing, and EM importers; may support risk assets generally while elevating scrutiny of tanker insurers, compliance teams, and Gulf shipping risk premia.
