Aramco’s Dual-Loading Move Signals Supply Chain Breakdown Risk as Yanbu Hits Max Capacity

The closure of the Strait of Hormuz has created a massive, immediate supply shock. The waterway, through which about 20% of the world's oil and gas is shipped, has seen traffic effectively halted. This chokepoint is critical for Saudi Arabia, which exported around 6 million barrels per day through the Strait before the war shut it in late February. The disruption is not isolated. Iraq, the second-largest OPEC producer, has already been forced to cut output by nearly 1.5 million barrels a day due to a lack of export routes and storage limits, a move that has further tightened the market.

This is where Aramco's operational response signals acute stress. In a direct move to reroute supply, the company has asked Asian buyers to submit two nomination plans for April shipments-one for its main Persian Gulf terminal at Ras Tanura, and another for its Red Sea terminal at Yanbu. This dual-loading requirement is a logistical pivot, forcing buyers to plan for alternative, longer routes. The data shows the scale of this shift: Yanbu loadings have averaged 2.2 million bpd in the first nine days of March, up from 1.1 million bpd in February, as the company moves crude through its pipeline to the Red Sea.

The pressure is now building from the demand side. Even as supply faces these physical constraints, Aramco itself has forecast a 1.1 million barrels per day increase in global oil demand for 2026. This projection, made by the world's largest exporter, directly pressures an already strained supply chain. The market is caught between a contracting supply pipeline and a forecasted surge in consumption, a dynamic that has already driven Brent crude to its highest levels since January 2025.

Aramco's Logistics Response: Capacity and Constraints

Aramco's immediate answer to the Hormuz blockade is a logistical pivot, but its viability hinges on physical capacity. The company is asking Asian buyers to submit two nomination plans for April shipments-one for its main Persian Gulf terminal at Ras Tanura, and another for its Red Sea terminal at Yanbu. This dual-loading requirement is a direct operational response, forcing buyers to plan for alternative, longer routes to keep crude moving.

The core of this strategy is the East-West pipeline. Aramco is ramping up the volume of oil it sends through this pipeline, which has a capacity of up to 7 million barrels per day. This pipeline is one of the two major routes available to bypass the closed Strait of Hormuz. CEO Amin Nasser has stated the company should be reaching this capacity "within a couple of days," framing it as a critical buffer. The plan is to maintain production at this pipeline level if needed, with the ability to return to normal operations "in days and not weeks" once the bottleneck clears.

Yet, the current reality reveals a key constraint. While the pipeline can move 7 million bpd, the actual Yanbu loading capacity is around 2.2 million barrels per day. This figure is the real-world limit for getting crude onto tankers via the Red Sea alternative. The company has already begun to push this capacity, with Yanbu loadings averaging 2.2 million bpd in the first nine days of March, up from 1.1 million bpd in February. This ramp-up shows the system is being stressed to its current maximum, but it also highlights that the pipeline's full 7 million bpd capacity is not instantly convertible to export volume. The bottleneck shifts from the Strait to the terminal and port infrastructure at Yanbu.

The bottom line is that Aramco's alternative logistics are a stopgap, not a complete solution. The East-West pipeline provides a vital conduit, but the finite loading capacity at Yanbu means the company cannot fully offset the loss of the 6 million bpd of export volume that once flowed through Hormuz. This creates a persistent supply gap that will keep pressure on the market until either the pipeline's export capacity is expanded or the Gulf route reopens.

The Imbalance: Lost Production vs. Available Flow

The supply-demand picture is now starkly out of balance. The combined loss from the Hormuz halt and Iraqi production cuts represents a potential 180-million-barrel disruption in the market. That figure breaks down to roughly 6 million barrels per day of lost Saudi export volume through Hormuz and nearly 1.5 million barrels a day from Iraq. This is a massive contraction in available supply.

This contraction dwarfs the projected demand growth. Even as supply shrinks, Aramco itself forecasts a 1.1 million barrels per day increase in global oil demand for 2026. The market is facing a simultaneous squeeze: a supply loss of 7.5 million bpd (the sum of the two cuts) against a demand increase of 1.1 million bpd. The imbalance is severe and immediate.

The pressure is already showing in inventory levels. Aramco's CEO has warned that a prolonged halt would accelerate the pace of drawdowns at global inventories, which are already at a five-year low. This is a critical vulnerability. With stockpiles thin, there is little buffer to absorb the shock of the supply loss. Any further disruption could quickly deplete these reserves, tightening the market even more.

The market's reaction has been swift and clear. On recent escalation, oil prices rose more than $1, with Brent crude hitting its highest level since January 2025. This price surge is a direct signal of the tightening supply. It reflects traders pricing in the risk of a prolonged disruption and the thin inventory cushion. The imbalance is no longer theoretical; it is being priced into the market.

Catalysts and Risks: What to Watch

The immediate pressure is clear, but the path forward hinges on a few critical signals. The market is now a waiting game, watching for any shift in the physical or political conditions that could ease the acute supply chain stress.

First, monitor the status of the East-West pipeline. CEO Amin Nasser has stated the company should be reaching its capacity of up to 7 million barrels per day "within a couple of days." This is the operational heartbeat of the alternative route. Any delay in hitting or maintaining this volume would confirm the pipeline's limitations and intensify the supply gap. More broadly, watch for any further production cuts from Saudi Arabia or other Gulf producers. The company has reportedly begun reducing oil production at two fields as the disruption takes hold, a move that would directly shrink available supply if it expands.

The most powerful catalyst for relief would be a de-escalation in U.S.-Iran-Israel tensions. The closure of the Strait of Hormuz is a political act, and its reopening is a political decision. Any diplomatic breakthrough or ceasefire announcement would be the single biggest signal that the physical bottleneck is lifting. The market's reaction to recent escalations has been swift, with prices surging on each new strike. The reverse should hold true.

Finally, track global inventory levels and price volatility for signs of sustained pressure. Aramco's CEO has warned that a prolonged halt would accelerate the pace of drawdowns at global inventories, which are already at a five-year low. If stockpiles continue to fall sharply, it would confirm the thin buffer is being consumed, increasing the risk of a more severe market squeeze. Price volatility itself is a key indicator. The recent surge to highs not seen since early 2025 shows the market is pricing in high risk. Continued choppiness or new peaks would signal that the perceived supply threat remains acute.

The bottom line is that the current stress is a function of both physical constraints and geopolitical risk. The market will watch the pipeline's output as a measure of operational resilience, but the ultimate resolution depends on the political situation. For now, the warning of "catastrophic consequences" for the global economy if the disruption continues underscores the high stakes.
