How the Strait of Hormuz crisis created a shipping cost inflation shock

Earlier in the crisis, daily traffic had averaged roughly three tankers per day, about one-tenth of normal volumes . A separate UN Trade and Development report based on Clarksons data showed a 97% drop in daily ship transits in the first days after the conflict began in late February 2026 .

The recovery has been fragile. A June 2026 U.S.-Iran interim agreement briefly boosted traffic — 125 transits were recorded in the week after the ceasefire — but a renewed attack on a cargo ship on June 24 shattered confidence . By July, the U.S. blockade had been reimposed, and the strait was once again effectively closed to commercial traffic .

Container freight rates hit a 2026 high

Container shipping costs have surged in lockstep with the Hormuz disruption. Drewry's World Container Index (WCI) rose 2% week-over-week to $4,639 per 40-foot container on July 9, 2026, its highest reading since September 2024 . The rally was led by Asia-Europe routes:

• Shanghai–Rotterdam: $4,933 per FEU (up 5%)
• Shanghai–Genoa: $6,463 per FEU (up 2%)
• Shanghai–Los Angeles: $6,482 per FEU (up 2%)
• Shanghai–New York: $7,904 per FEU (unchanged)

The WCI had been climbing steadily through mid-2026, with earlier readings of $3,969 in mid-June (up 12% week-on-week) and $3,549 in early June .

Claims of a specific 120% surge in transpacific spot rates (Asia to U.S. West Coast) and an 85% rise to the East Coast could not be directly confirmed from the sources searched. The evidence shows transpacific rates were firm, but the specific percentages require a primary source.

CMA CGM's emergency fuel surcharge: a direct pass-through to consumers

On July 22, 2026, French shipping giant CMA CGM announced an emergency fuel surcharge ranging from $65 to $165 per container, effective August 1, citing renewed escalation of hostilities in the Strait of Hormuz . The surcharge will remain in place until further notice .

CMA CGM’s own advisory (Advisory #12) provides the breakdown: long-haul head hauls will be charged $150 per TEU for dry containers and $165 per TEU for reefer containers . Back hauls are set at $75/TEU (dry) and $90/TEU (reefer) .

The trigger: bunker fuel prices reversed their recent decline. Very low sulfur fuel oil (VLSFO) prices climbed above $800 per metric ton in Fujairah and LA/Long Beach, near $785 in Singapore, and above $700 in Houston . Marine gas oil (MGO) prices exceeded $1,370 per metric ton in Fujairah and LA/Long Beach .

As one analysis put it: "Your shelves will feel it" .

Global trade: record nominal values, but price-driven growth

The broader trade picture shows an economy operating under significant price pressures. UNCTAD's Global Trade Update (July/August 2026) estimates global goods trade reached approximately $13.7 trillion in H1 2026, up 12.5% from the same period in 2025 . Services trade grew 10.5%, and combined goods and services added about $2 trillion to global trade, putting it on course for a record annual value .

However, UNCTAD noted that the expansion was "supported in part by higher prices" rather than purely physical volume growth . In a separate report, the World Bank confirmed that global trade values continued to rise in early 2026, but cautioned that the gains were partly price-driven . The UN's World Economic Situation and Prospects 2026 projects global growth slowing to 2.7% in 2026, below both 2025 levels and the pre-pandemic average .

The central bank dilemma: cost-push inflation that rate hikes can't fix

The shipping cost inflation from the Hormuz crisis is a textbook example of a supply-driven (cost-push) shock. Bunker fuel prices have risen sharply, feeding directly into transport costs and then consumer prices. This creates a stagflationary dilemma for central banks: raising interest rates to combat price increases would further dampen demand and growth, but doing nothing risks embedding higher inflation expectations.

The mechanism is well-established in macroeconomic theory and is strongly supported by the evidence from the current crisis. However, no specific central bank statement addressing the Hormuz-linked inflation was captured in the search.

What comes next

The shipping cost inflation triggered by the Hormuz closure is not a transitory blip. With vessel transits at a fraction of pre-crisis levels, container rates at multi-year highs, and emergency surcharges being applied to every container moving through affected trades, the cost pressures are feeding directly into global supply chains. Central banks face a dilemma that has no clean solution — and consumers will feel it on every shelf.
