Trade routes are never permanent
The shipping lanes that carry 80% of global trade by volume are not natural features — they are the accumulated result of geography, technology, commerce and geopolitics. All of those forces are shifting simultaneously, with consequences that will play out over decades.
The Panama Canal constraint
A drought in 2023-2024 lowered Gatun Lake water levels enough to restrict the number of ships that could transit daily. The canal handles about 5% of global trade and was for months operating at roughly two-thirds capacity, forcing ships to reroute around Cape Horn — adding weeks and significant fuel costs.
The Arctic opportunity
As Arctic sea ice retreats, the Northern Sea Route and Transpolar Route offer dramatically shorter distances between Europe and Asia. The Northern Sea Route is already commercially used during summer months, primarily by LNG tankers.
The China Plus One effect
US tariffs on Chinese goods and broader concerns about supply chain concentration are driving manufacturers to add production capacity in Vietnam, India, Malaysia, Mexico and Eastern Europe. China's export volumes have not collapsed, but its share of some supply chains is declining.
