Hormuz closure becomes the worst trade disruption in eight decades

Global trade is facing its worst disruption in 80 years as supply chain bottlenecks in the Strait of Hormuz threaten global food and fertiliser supplies, the head of the World Trade Organization said^1,2. Traffic through the strait has collapsed. Four commodity vessels transited the Strait of Hormuz in the Persian Gulf, down from six a day earlier and below the ten-day average of about 16³. Reuters described the strait as still largely cut off, with just four commodity vessels passing through on Thursday⁴.

The United States is managing the flow rather than restoring it. US Central Command said on Saturday that more than one billion barrels of crude oil had transited the strait under the US blockade⁵, and that it has redirected 105 commercial vessels since enforcing that blockade¹⁴.

Why it matters to investors

Freight is repricing off the chokepoint. Asia to US container rates have soared past $11,000, near pandemic records, and the East Coast spot rate is just 11.2 per cent below its record of $12,683 per forty-foot equivalent unit, set on 1 January 2022⁶. Congestion has spread to unrelated routes: Panama Canal auction slots have reached a record $5.3 million, with waiting times rising to 17 days amid surging demand⁷.

Fuel is the channel that reaches households. Diesel prices are at record highs⁸, with gasoline at $4.44 and diesel at a record $6.40⁹, while the US national average for gasoline has climbed 16 cents in a week to $4.46¹⁰. Diesel costs for US farmers have doubled, and a senator has pressed the agriculture secretary on the squeeze¹¹. Because diesel is the lifeblood of the supply chain, higher fuel costs may show up in the prices wholesalers charge⁸.

What to watch

Forecasting has broken down at the top of the market. JP Morgan said it had assumed there would be economic red lines, such as oil at $100 a barrel, that the United States would be unwilling to cross¹². Shipowners are not waiting for clarity: a $20 billion tanker ordering spree has begun as buyers turn to crude produced in the Americas, which must be shipped on long transoceanic voyages¹³.

The de-escalation signals are worth tracking as closely as the disruption. Oil slid after China asked Iran to limit Houthi attacks on Saudi oil facilities⁴. Transit counts remain the cleanest daily indicator of whether the chokepoint is reopening^3,5.
