Saudi Crude's Fragile Reroute to Pakistan Highlights Market’s Stretched Supply Balancing Act

The journey of a single oil tanker is now a key signal for the global oil market. On a recent Saturday, the oil tanker P. Aliki set sail from the Persian Gulf, carrying a cargo of about 650,000 barrels of Saudi crude to Pakistan. Its path was a deliberate and narrow one, hugging the Iranian coastline through the narrow gap between the two Iranian islands of Larak and Qeshm. This was not a routine voyage. It was one of seven vessels visible leaving the Gulf that day, a small but significant flow that underscores a major shift in energy trade.

This physical rerouting is a direct response to a severe disruption. Since the start of the U.S.-Israeli strikes on Iran, traffic through the Strait of Hormuz has plunged by more than 95 percent. The waterway, which normally handles a quarter of the world's oil, is now a high-risk chokepoint where passage is granted only after securing Tehran's approval. The P. Aliki's route exemplifies the new, fragile order: a small, sanctioned flow of crude moving through a narrow corridor under Iranian control, while thousands of other vessels remain stranded.

The fragility of this new flow is stark. Even the limited number of tankers allowed to transit do so under conditions of high uncertainty. Vessel-tracking data is hampered by electronic interference and many ships disable their AIS transponders in high-risk waters. This means the actual number of transits may be higher than reported, but the data we have shows a flow that remains at a small fraction of prewar levels. The recent approval for seven Malaysian tankers and 20 more Pakistani-flagged ships is a step toward normalizing trade, but it does not yet represent a return to the strait's former capacity.

For Saudi Arabia, this is a critical test of its pivot. The kingdom has been ramping up oil exports through its East-West Pipeline to the Red Sea, with flows through that route surging from an average of 770,000 barrels per day in early 2025 to over 2.9 million bpd recently. The shipment to Pakistan is a physical manifestation of that strategy, using a different, more direct route to reach Asian markets. Yet, the continued reliance on a handful of sanctioned tankers navigating a perilous strait highlights the vulnerability of this pivot. It is a stopgap measure, not a permanent solution, and it underscores the immense pressure on the global supply chain to find stable alternatives.

The Rerouting Mechanics: Capacity Limits and System Stress

The physical rerouting of Saudi crude is a feat of engineering, but it is hitting hard limits. The kingdom's primary alternative export route, the 7 million barrels per day East-West pipeline to Yanbu, has now reached its full capacity. Despite this, flows through the pipeline remain insufficient to compensate for the loss of the Strait of Hormuz, which previously handled around 15 million barrels per day of crude. This creates a stark imbalance: the pipeline is operating at maximum tilt, yet the gap it must fill is immense.

The numbers reveal the strain. Saudi Arabia has moved about 7 million barrels per day through the pipeline recently, but a significant portion of that volume is consumed domestically. Exports from the Red Sea port of Yanbu are currently around 5 million barrels per day, with an additional 900,000 barrels per day of refined products also shipped. The pipeline also supplies roughly 2 million barrels per day to domestic facilities along the Red Sea coast. In total, the system is moving a substantial flow, but it is still far short of the pre-disruption export capacity that flowed through the Gulf.

This capacity crunch is not unique to Saudi Arabia. The broader market impact is defined by a massive, forced contraction in supply. Gulf countries have cut total oil production by at least 10 million barrels per day, a volume that must be absorbed by the alternative routes. The East-West pipeline, even at full capacity, cannot carry that load. This creates a fundamental pressure point: the market must find a way to move this displaced crude, but the infrastructure simply isn't there to do it quickly or efficiently.

The stress is evident in the operational details. The pipeline's full capacity is a testament to Saudi Arabia's contingency planning, but it also highlights the fragility of the new system. The recent attack on the Samref refinery in Yanbu, which prompted a temporary halt to exports, shows how vulnerable this concentrated flow can be. Any disruption to the pipeline or its Red Sea terminals would immediately tighten the bottleneck further. The system is now operating at the edge of its physical limits, with the entire weight of a major supply disruption resting on a single, overburdened artery.

Market Balance: Price Volatility Against a Glutting Fundament

The market is caught in a powerful tug-of-war. On one side, the physical disruption to the Strait of Hormuz is driving prices sharply higher. On the other, the underlying supply-demand fundamentals point toward a severe oversupply. This conflict between a volatile price signal and a glutting market is the core tension defining the oil trade today.

The price spike is undeniable. Brent crude futures have surged over 50% since the conflict began, reaching a high of $112.57 per barrel on March 27. This move reflects the acute risk premium for a chokepoint that now handles a fraction of its former volume. Yet, this surge sits in stark contrast to the sobering long-term outlook from major banks. J.P. Morgan Global Research sees Brent crude averaging around $60 per barrel in 2026, citing "soft supply-demand fundamentals." The bank argues that while geopolitical risks fuel volatility, protracted supply disruptions are unlikely, and the market is structurally headed for a surplus.

The International Energy Agency's warning underscores this fundamental imbalance. The agency projects a supply glut peaking at 4.5 million barrels per day in the second quarter of 2026. This forecast is built on a clear divergence: global oil supply is set to grow by about 2.5 million barrels per day in 2026, while demand expands by roughly 930,000 b/d. Even with recent production cuts, the market is on track for a major overhang. The agency notes that while inventories were briefly rebalanced in December, they remain "bloated" and are now being pushed higher by new supply injections.

This creates a precarious setup. The physical rerouting of Saudi crude through the East-West pipeline and the narrow Iranian corridor is a stopgap that cannot resolve this fundamental glut. It merely shifts the point of vulnerability. The pipeline is operating at full capacity, but that capacity is insufficient to offset the loss of the Hormuz route while also meeting global demand. The result is a market where price is being driven by short-term fear of a supply shock, while the structural reality is one of ample, growing supply. The volatility is a symptom of the disruption, but the underlying balance sheet points to a market that will need significant, likely involuntary, production cuts to avoid a deep inventory build.

Catalysts and Watchpoints: The Path to Resolution or Escalation

The market's current volatility hinges on a few critical variables. The path forward will be determined by whether the physical rerouting can be sustained, whether new disruptions emerge, and how quickly storage can absorb the displaced crude. The key watchpoints are clear.

First, monitor the status of the proposed U.S. insurance program for shipping through Hormuz. This initiative is the most direct potential catalyst for de-escalation. If implemented, it could restore flows through the strait, providing a much-needed relief valve for the global supply chain. The absence of such a program, however, leaves the market reliant on the fragile, sanctioned corridor and the overburdened East-West pipeline. Any delay or failure in launching the insurance scheme would prolong the current state of high-risk, low-capacity transit.

Second, watch for further Iranian actions that could disrupt the Red Sea alternative. The recent attack on the Samref refinery in Yanbu, which prompted a temporary halt to exports, is a stark reminder of the vulnerability of this concentrated flow. The situation is now more complex with Yemen's Houthi rebels entering the conflict directly. Their missile launch at Israel on March 28 marks a new escalation point. Any coordinated effort by Iran and its proxies to target the Bab el-Mandeb Strait or Red Sea shipping lanes would immediately tighten the bottleneck and likely trigger another sharp price spike.

Finally, track the pace of storage drawdowns and the resilience of key product markets. The International Energy Agency projects a supply glut peaking at 4.5 million barrels per day in the second quarter of 2026. For this glut to be absorbed, storage must draw down significantly. Yet, global oil stocks were already at a high of 8.21 billion barrels in January, and the IEA notes they are now being pushed higher. The diesel and jet fuel markets are particularly vulnerable. The agency estimates the conflict will curb global oil demand by around 1 million barrels per day during March and April due to widespread flight cancellations and disrupted LPG supplies. If these product markets show signs of weakness, it would signal that the fundamental oversupply is real and that the market may not be able to support current high prices for long.

The bottom line is that the current setup is a race between the speed of political resolution and the rate of inventory accumulation. The market is pricing in acute risk, but the structural fundamentals point toward a surplus. The watchpoints above will reveal which force gains the upper hand.
