UN Trade and Development says global seaborne trade recovered in 2023 but the shape of shipping has shifted markedly as longer, diverted voyages and surging freight rates reshape demand and strain connectivity for vulnerable economies.
The organisation reported that global maritime trade grew by 2.4 percent to 12.3 billion tonnes in 2023 following a contraction in 2022, a rebound that, UN Trade and Development warned, has been accompanied by structural changes to routes and cargo flows rather than a simple return to previous patterns.
Longer voyages lift demand for ton‑miles and boxes
UN Trade and Development found that the move to lengthier voyages raised global vessel ton‑mile demand by 3 percent while container‑ship demand increased by 12 percent, figures that reflect both additional distance sailed and altered deployment of box tonnage across longer services.
The report attributes much of this shift to major route changes: Suez Canal transits were reported to be 70 percent lower by mid‑2024 than before the disruption, while arrivals via the Cape of Good Hope had risen by 89 percent, indicating sustained diversion of traffic around southern Africa in the months after the incident.
Disruptions in the Panama Canal were also highlighted, with affected routes experiencing an increase in sailing distances of 31 percent, a change that UN Trade and Development says has material effects on scheduling, vessel utilisation and the demand profile for larger long‑haul trades.
Costs, connectivity and policy response
Freight markets have reacted strongly to these route and capacity shifts: the report noted that the Shanghai Containerized Freight Index had more than doubled by mid‑2024 compared with late 2023, signalling a rapid rise in the cost of moving boxes on affected east–west lanes and the broader contagion into global freight rates.
UN Trade and Development also sounded an alarm over connectivity: shipping‑connectivity levels for small island developing States fell by 9 percent over the preceding decade, a decline the organisation linked to increased vulnerability when chokepoints are disrupted and to the rising economic cost of longer, less frequent services for import‑dependent economies.
To address those risks the report set out a compact set of measures, calling for resilient infrastructure, improved chokepoint monitoring, route diversification, international cooperation and targeted support for vulnerable economies; these policy priorities were presented as necessary to reduce exposure and to smooth the economic impact of future interruptions.
- Resilient infrastructure
- Improved chokepoint monitoring
- Route diversification
- International cooperation
- Support for vulnerable economies
The analysis from UN Trade and Development makes clear that the industry is no longer assessing capacity and demand only in terms of tonnage and terminal throughput but must also factor the growing importance of distance, rerouting and concentrated chokepoints in determining fleet needs and commercial strategy.
Taken together, the report's figures imply that shipowners, liners and policymakers must plan for a more variable operating environment in which higher ton‑mile demand and volatile freight indices coexist with the longstanding challenge of maintaining reliable links to small and vulnerable states; the organisation's recommendations aim to temper those tensions and to preserve the economic role of seaborne trade.
