The crisis in the Strait of Hormuz has introduced a new factor into the container freight market: a geopolitical surcharge that industry operators have begun to call the “Hormuz Premium”. This is not a short-lived speculative spike, but a persistently higher and more volatile average cost level that has been superimposed on historical seasonal curves, making them effectively unusable as a planning benchmark. According to Sea-Intelligence, spot rates on several east-west routes are several hundred dollars per 40-foot container above levels considered normal for the same time of year, despite little or no corresponding increase in actual physical demand. This differential is neither uniform nor stable. It fluctuates sharply in response to geopolitical developments and operational decisions by major carriers, but does not return to historical parameters even during periods of relative calm.
The mechanism through which Hormuz-related risk translates into a premium on container freight rates operates at several levels. The first concerns energy costs: pressure on oil and refined product prices generated by the Gulf crisis feeds directly into freight rates through bunker adjustment factors and related surcharges, as highlighted by Drewry and other industry analysts. The second level concerns insurance premiums. War-risk costs on Middle Eastern routes have risen sharply, and many shipping companies have introduced specific surcharges even for services that do not pass directly through the Gulf but are affected by the wider consequences. The third factor is the reduction in effective available capacity. Ships are being diverted onto longer routes to avoid high-risk areas, increasing sailing times, fuel consumption and the amount of capital tied up. Some market analyses have also reported rolled containers and restricted upstream capacity, suggesting that certain carriers are seeking to keep supply artificially tight despite unexceptional demand, using geopolitical uncertainty to support spot-rate levels.
The combined effect of these factors has profoundly distorted traditional seasonality. Under normal conditions, the ocean freight curve shows a peak ahead of Chinese New Year, a decline in late spring and a renewed rise towards the third quarter, coinciding with the peak import season in the United States and Europe. In 2026, this pattern did not materialise. On the main Asia-North America and Asia-Europe corridors, following the usual post-holiday rebound, rates rose abnormally instead of stabilising at lower levels in late spring, diverging from patterns seen in previous years. On the transpacific, the post-holiday decline was initially pronounced, but rates then reversed direction and climbed above the seasonal average, without the usual low-season interval.
On the Asia-Northern Europe route, the divergence from the average curve emerged earlier and with more pronounced fluctuations. An initial increase above expected seasonal levels was followed by partial normalisation and then a renewed rise, with spot rates remaining consistently above typical late-spring values. The Mediterranean route has shown an even more volatile pattern, with early peaks, a return towards normal levels and a renewed move towards previous highs. This points to a risk premium that is particularly sensitive to developments in the Gulf and to rerouting decisions.
According to analyses cited by Global Trade Magazine and international logistics operators, rates on some Asia-Europe routes are currently several hundred dollars per 40-foot container higher than at the corresponding seasonal point in previous years. This is occurring in a market where diversions via the Cape of Good Hope, already adopted to bypass the Red Sea, had altered capacity and transit-time parameters during 2024 and 2025. The Hormuz crisis has therefore affected a market that was already operating outside historical norms, amplifying the impact and extending the period of instability.
There are several implications for shippers and supply chain managers. The traditional peak-season calendar must be rewritten. The period during which freight rates are at high risk of remaining elevated now extends from the end of the second quarter into the autumn, effectively making the old pattern, which concentrated pressure in July and August, obsolete. Freight budgets based on historical averages are systematically underestimated, because fluctuations around a reference curve have been replaced by a higher and broader range of possible outcomes. The contagion effect on indirectly affected routes must also be considered. Even companies that do not use Gulf corridors directly may face higher rates as a result of bunker costs, risk premiums and the redistribution of global capacity, as shown by increases on the transpacific despite only moderate demand. For sectors handling highly perishable products, including fresh produce and fast-moving consumer goods, delays caused by diversions and congestion, combined with structurally higher freight rates, are eroding margins and forcing companies to reassess storage strategies, safety stocks and sourcing decisions.
Analysts stress that not all of the differential can be attributed solely to the Hormuz crisis. The premium interacts with disruption in the Red Sea, macroeconomic demand trends and carriers’ capacity policies. However, as long as security risks in the Gulf remain high, insurance premiums do not fall and carriers maintain cautious supply policies, the structural premium is likely to continue compressing traditional seasonality into a prolonged period of elevated volatility. According to analysts at Sea-Intelligence and Metro Global, the metrics to monitor include the gap between spot rates and historical seasonal curves on Asia-Europe, Asia-Mediterranean and transpacific routes; trends in fuel prices and Middle East risk-related surcharges; changes in war-risk premiums and the high-risk-area lists maintained by major insurers; and decisions by leading carriers on whether to return to standard routes through the Suez Canal, which have a decisive influence on the effective capacity available in the market.
