Hormuz nearly blocked, Panama Canal hit by drought: How geopolitical and climate shocks are rerouting maritime trade

For the first time in the history of global trade, a Chinese shipowner has opened a regular freight route linking Asia and Europe through the Arctic. Sea Legend’s container ship Dubai Tower left the Chinese port of Ningbo in mid-August and was due to reach the United Kingdom within days.

The vessel is the first in a planned weekly service running until October, when the crossing becomes impossible without an icebreaker. The Arctic route has become viable partly because climate change has melted sea ice, offering shipping companies an alternative as established corridors face mounting disruption.

The reorganization of maritime traffic is being driven by both geopolitics and climate. In recent weeks, Houthi rebels have resumed attacks on Western-linked shipping in the Bab al-Mandab strait, the gateway to the Suez Canal. The Strait of Hormuz is described as nearly blocked, while drought is affecting the Panama Canal.

The pressure is also being felt at major Asian ports. Since August 28, typhoon Saudel has battered Shanghai and Ningbo, the world’s two largest container ports. More than 2.4 million containers have been left waiting at the quays, with loading delays increasing.

The result is a scramble for alternatives. The Arctic route offers one possibility, but its use remains tied to seasonal conditions and the need for icebreaker support later in the year.
