Shipping Giants Face Squeeze as Rerouting Costs and Delays Spiral Under Hormuz Closure

The immediate toll of the closed Strait of Hormuz is being felt across the commodity complex. The narrow waterway, a chokepoint for roughly 20% of global oil and LNG supply, has been effectively shut since late February. This halts daily shipments of about 20 million barrels of oil, a volume that represents a significant chunk of the world's daily petroleum liquids consumption.

Top producers like Saudi Arabia, Iraq, and Kuwait have been forced into a difficult choice. With no way to load tankers, they must pump oil directly into storage. But their facilities are now brimming after 10 days with no shipping, leaving them with no option but to cut production at their oilfields. This creates a direct supply squeeze at the source.

The disruption extends far beyond oil. The strait is also a critical artery for other essential commodities. Experts warn that supply chains for aluminum, fertilizers, and rubber are now under threat. The impact could hit prices across a wide range of products within weeks, as the ripple effects spread through global manufacturing and trade.

Rerouting: Volume, Costs, and Capacity Limits

The scale of the rerouting is staggering. Container shipment diversions have surged more than 360% since the strait's closure, jumping from a baseline average of 218 shipments per day to roughly 1,010 per day. The peak was recorded on March 5, when over 2,300 diversions were logged in a single day. This massive volume shift is being executed by all major carriers, with Maersk and Hapag-Lloyd leading the charge by rerouting vessels around Africa.

This alternative route, the Cape of Good Hope, adds weeks to transit times. As one analyst noted, adding an extra 10 days to the journey artificially reduces a ship's available capacity and drives up the rates carriers can charge. To cover the added fuel, crew, and operational costs, companies are applying "war risk surcharges". While these surcharges can be a financial tailwind for shipping lines, they represent a direct cost increase for shippers and, ultimately, consumers.

The pressure is now hitting the receiving ports. The sudden influx of diverted cargo is overwhelming infrastructure. At India's key gateways, the delays are severe: arrival and departure delays have increased by as much as 49 days. Mundra Port has seen departure delays climb by 72%, while Navi Mumbai's departure delays have jumped 118%. This congestion is a clear sign that the receiving network lacks the spare capacity to absorb such a rapid volume spike without significant bottlenecks.

The situation is further complicated by the suspension of operations at critical hubs. The Port of Salalah has halted activities, removing another potential offload point. Other ports like Khor Fakkan, Sohar, and Hambantota are absorbing the bulk of the diverted freight, but they are now at risk of their own operational delays as they adjust to this unprecedented load. The rerouting is not a simple swap; it is a massive, costly reallocation that is straining the entire global container network.

Commodity Balance Implications: Supply Held Up vs. Demand Met

The rerouting crisis is now translating into tangible market signals. For aluminum, the early signs of tightening are clear. Prices are already rising, a direct response to the threat of a disrupted supply chain from the Gulf. This is a critical industrial input, and the region is a major source, accounting for a significant share of global unwrought and wrought aluminum imports. The price move indicates that the market is pricing in the risk of a supply squeeze before it fully materializes.

This persistent rerouting creates a new, permanent layer of cost. The added weeks to transit times and the application of war risk surcharges are not temporary inconveniences. They represent a sustained increase in trade costs that will be passed down the line. For consumers, this means higher prices for a wide range of goods, from electronics and batteries to the finished products made with aluminum and rubber. The cost of moving goods around the Cape of Good Hope is now a new baseline.

The broader lesson is one of acute vulnerability. The current crisis underscores how much global trade relies on a handful of narrow chokepoints. The Strait of Hormuz is the most obvious example, but the Suez Canal and the Panama Canal are also critical arteries. The Suez, which handles a tenth of global seaborne trade, is not immune to accidents or political pressure, as the grounding of the Ever Given demonstrated. The rerouting of tens of thousands of containers around Africa is a stark reminder that when one of these bottlenecks fails, the entire system must find a way around it, often at great expense and delay. The commodity balance is under pressure not just from halted flows, but from the costly, inefficient detours that are now the new normal.

Catalysts and What to Watch

The trajectory of this crisis hinges on a single, volatile variable: the political status of the Strait of Hormuz. A swift reopening would rapidly dismantle the current rerouting infrastructure. With the strait cleared, the 1,010 daily diversions would collapse, easing congestion at ports like Sohar and Hambantota and allowing carriers to resume direct, efficient sailings. This would immediately reduce the costly war risk surcharges and fuel premiums that are now a new baseline.

For now, the strain is likely to intensify on specific trade lanes. Further port congestion and rate increases are probable, particularly on routes to South Asia and the Middle East. The average price of very low sulphur fuel oil (VLSFO) has already surged more than 80% since the closure, and carriers are preparing to implement new surcharges and General Rate Increases. This will continue to push up the cost of goods moving through these affected corridors.

The most significant risk is escalation. Any further military action or political miscalculation could extend the closure indefinitely or trigger a wider regional conflict. This would not only prolong the rerouting nightmare but could also disrupt other critical chokepoints like the Suez Canal, amplifying the global trade shock. The situation remains fluid, with the primary catalyst being the political will to reopen the strait.
