Why global ocean freight rates are rising again

Global ocean freight rates have surged in recent weeks as shipping lines face a combination of early peak-season demand, port congestion and geopolitical disruptions. According to Drewry's World Container Index (WCI), the benchmark index jumped 23% to USD 3,433 per FEU in early June and subsequently increased to USD 3,549 per FEU, reflecting strong upward pressure across major trade lanes. Drewry confirmed that the 2026 peak season started earlier than usual, supporting higher cargo volumes and freight rates.

The primary reason is the export peak season in China. Manufacturers are accelerating shipments to the United States, Europe and other consumer markets ahead of year-end demand. As a result, shipping lines have redeployed vessels toward the Transpacific and Asia-Europe trades where freight returns are higher. Drewry reported that rates from Shanghai to Los Angeles and Shanghai to New York have risen sharply as carriers respond to increased cargo demand.

A second major factor is congestion at key transshipment hubs such as Singapore and Colombo. Vessel waiting times of several days are disrupting sailing schedules and creating a ripple effect across global supply chains. When a vessel misses its berth window at a transshipment hub, delays spread across multiple service loops, reducing effective capacity despite the availability of ships in the global fleet. Congestion across Asia is increasingly affecting schedule reliability and equipment availability.

Several additional factors are contributing to the rate increase. Geopolitical tensions in the Middle East have pushed bunker fuel prices higher and created uncertainty around shipping routes and operating costs. Rising fuel expenses and emergency surcharges are being passed through the supply chain, adding further upward pressure on freight rates. Reuters reported that container rates on key Asia-US routes have nearly doubled since the escalation of tensions involving Iran and the Strait of Hormuz.

Drewry's Intra-Asia Container Index also reached a record high during June, highlighting strong regional demand and persistent congestion. Freight rates from China to South Asia increased significantly as shippers advanced cargo movements to avoid future disruptions and higher transportation costs.

However, the current rally is unlikely to continue indefinitely. The increase is largely driven by seasonal demand and temporary network disruptions rather than a structural shortage of vessels. Global container shipping capacity has expanded significantly over the past two years as newbuild vessels entered service. Historical freight patterns show that rates often soften once the peak export season concludes. Drewry and other market analysts have repeatedly noted that excess capacity remains a longer-term challenge for carriers despite short-term rate spikes.

Therefore, unless geopolitical tensions worsen significantly, freight rates are expected to remain firm through July and August before gradually declining from September 2026. As China's peak shipping season eases and congestion at Singapore and Colombo improves, additional vessel capacity should return to the market, reducing pressure on freight rates and improving schedule reliability.
