THE NEWS

According to OilPrice.com, Saudi Arabia's crude exports through the Red Sea port of Yanbu have declined 41% from their March peak, falling to approximately 2.39 million barrels per day (bpd) by June, down from 4.07 million bpd at the peak. The figures come from Wood Mackenzie vessel tracking and cargo data. The contraction has been steady rather than abrupt, occurring across the months following the March high point.

The context for the March surge was Saudi Arabia's decision, at the outset of the conflict involving Iran, to redirect virtually all crude exports through its East-West pipeline to Yanbu on the Red Sea — effectively concentrating export volumes through a single terminal on the western coast. Despite that near-total concentration, volumes did not hold at peak levels and have trended downward since.

Wood Mackenzie's tracking methodology relies on vessel-level cargo data, making the 41% figure a flow measurement rather than a production or allocation estimate. The gap between the March peak of 4.07 million bpd and the June reading of approximately 2.39 million bpd represents a substantial reduction in Red Sea-routed crude availability.

WHY IT MATTERS

For Brazilian offshore professionals and operators, the significance of this data point is less about the Red Sea itself and more about what it implies for global crude routing, Atlantic Basin supply balances, and the relative pricing environment for Brazilian grades.

When Saudi Arabia redirected exports westward through Yanbu in March, it was responding to the strategic risk of Strait of Hormuz disruption. That decision temporarily flooded the Red Sea corridor with crude that would normally transit the Gulf. The subsequent 41% decline from peak suggests that either overall Saudi export volumes have been adjusted, routing has been partially reversed toward the Gulf, or both. The source article does not specify which dynamic is dominant, so caution is warranted in reading too much into the directional cause. What is clear from the Wood Mackenzie data is that the Red Sea corridor is carrying materially less Saudi crude in June than it was in March.

From a Brazilian supply-chain perspective, the Atlantic Basin crude market is sensitive to shifts in Saudi routing. When Middle Eastern barrels move westward through the Red Sea and Suez Canal, they compete more directly with West African and South American grades in European and North American refining markets. A reduction in Yanbu loadings, if it reflects lower overall Saudi export volumes rather than a routing shift back to the Gulf, would tighten Atlantic Basin supply and provide modest support to the price benchmarks against which Brazilian pre-salt crude is priced. If, on the other hand, the decline reflects a partial reversal of routing toward the Strait of Hormuz, the competitive picture for Atlantic Basin grades depends heavily on whether Hormuz passage has normalized.

For Petrobras and other Brazilian operators with long-term offtake agreements or spot exposure in Atlantic markets, the relevant question is how this Saudi volume adjustment interacts with current differentials for Brazilian grades. Pre-salt production, which is substantial and growing, competes in a global market where Saudi pricing decisions carry outsized influence. A period of reduced Saudi Red Sea loadings — whatever the underlying cause — tends to reduce the supply pressure on Atlantic Basin buyers and can support the netback economics of Brazilian exports.

Brazilian regulators and the ANP will also be watching the broader signal: geopolitical routing decisions by major producers have proven capable of generating sharp, short-duration price spikes and volume dislocations. The March peak at Yanbu was itself a product of conflict-driven rerouting rather than underlying demand growth. The Brazilian offshore sector, with its long investment cycles and multi-decade production profiles, is structurally exposed to these kinds of episodic volatility events. Understanding the routing mechanics — not just the headline price — is part of how operators manage that exposure.

Finally, there is a shipping dimension worth noting for Brazilian maritime stakeholders. The concentration of Saudi exports through Yanbu in March created a surge in Red Sea tanker demand and affected VLCC positioning globally. The subsequent normalization of those volumes has the opposite effect: it reduces spot demand on certain trade lanes and can affect freight rate benchmarks that Brazilian operators use when evaluating FOB versus CIF export structures. Tanker market participants operating in the Brazilian offshore logistics space should factor in that the March Yanbu peak was an anomaly driven by conflict-related rerouting, not a structural shift in Saudi export geography.

CONTEXT

Saudi Arabia's East-West pipeline, which connects the Eastern Province fields to Yanbu, has historically served as a contingency route precisely to reduce dependence on Strait of Hormuz passage. Its activation as the primary export corridor in March 2026 marked one of the more significant routing shifts in recent memory, and the Wood Mackenzie data now provides the first quantified picture of how that peak has unwound.

The broader pattern — a conflict-driven routing surge followed by a steady volume decline — is consistent with how commodity markets have responded to prior geopolitical disruptions in the Middle East. For Brazilian offshore professionals tracking global crude balances, the Wood Mackenzie vessel tracking methodology offers a more granular read on these dynamics than official export statistics, which typically lag by weeks. Monitoring that data stream is increasingly part of the commercial intelligence toolkit for operators active in Atlantic Basin markets.
