Review of Maritime Transport 2024

Food security, energy supplies and the global economy are at risk as key chokepoints like the Suez and Panama Canals and the Red Sea face growing pressure from geopolitical tensions and climate change.

In 2023, ship transits through these canals dropped by about half, forcing costly rerouting around Africa's Cape of Good Hope.

By mid-2024, Suez transits fell further, with ship capacity (tonnage) crossing the Gulf of Aden down 76% and tonnage transiting the Suez Canal cut by 70%. Cape of Good Hope arrivals surged 89%. Longer routes raised global vessel ton-mile demand by 3% and container ship demand by 12%.

Longer routes have increased costs for fuel, wages, insurance and chartering while boosting emissions. For a 20,000-24,000 TEU vessel on the Far East-Europe route, CO2 emissions alone add $400,000 in costs under the European Union's Emissions Trading System.

Regional examples show the wider impact. East African nations like Djibouti and Sudan, reliant on the Suez Canal for a third of their trade, face severe disruptions. The Panama Canal disruption has increased sailing distances by 31% for affected routes.

Small island developing States, reliant on maritime imports, have seen shipping connectivity drop by 9% over the past decade, leaving them ten times less connected than the rest of the world.

In 2023, global maritime trade grew by 2.4% to 12.3 billion tons, rebounding from the 2022 contraction. The sector is projected to grow by 2% in 2024 and an average of 2.4% annually through 2029.

However, soaring freight costs and an “exceptionally daunting operating landscape” driven by geopolitical conflicts and climate risks continue to weigh on a lasting maritime trade recovery.

Demand for iron ore, coal and grains remains strong, while the container trade – up just 0.3% in 2023 – is expected to rebound by 3.5% in 2024, contingent on supply chain stabilization.

A record of almost 250,000 port calls by container ships in the second half of 2023 were driven by growing trade and longer routes, causing some congestion, especially in Asia, which handles 63% of global container trade.

Ton-miles increased by 4.2% due to longer shipping distances from disruptions in key routes like the Suez and Panama Canals, further straining supply chains and adding to greenhouse gas emissions from shipping. 

Concerns are growing about a rise in fraudulent ship registrations and registries undermining safety, security, pollution control and seafarer welfare. Ongoing efforts by the International Maritime Organization (IMO) to tackle fraudulent ship registration underscore the urgency of addressing this issue.

Demand for greener, more resilient supply chains is encouraging shorter, regionally focused trade, potentially boosting intraregional maritime connections.

Freight rates surged in 2024 due to rerouting, port congestion and rising operational costs.

By mid-2024, the Shanghai Containerized Freight Index (SCFI) had more than doubled from late 2023, driven by longer shipping distances, higher fuel consumption and rising insurance premiums.

This surge in freight rates, if sustained, will push global consumer prices up, with UN Trade and Development projecting a 0.6% increase by 2025 due to higher shipping costs.

The impact is especially severe for vulnerable economies reliant on maritime transport, as rising costs erode trade competitiveness, threaten economic stability and drive inflation.

For example, small island developing States could see consumer prices rise by 0.9% by 2025, with processed food costs increasing by 1.3%, putting food security at risk.

Beyond the primary trans-Pacific and Europe-bound routes, spot freight rates also surged. From January to July 2024, the average rate on the SCFI Shanghai–South America route more than doubled to $9,026 per TEU, the highest level since September 2022.

During the same period, the SCFI Shanghai–South Africa route saw its average rate almost triple to $5,426 per TEU (the highest since July 2022), while the SCFI Shanghai–West Africa average rate jumped 137% to $5,563 per TEU (the highest since August 2022).

Shipping accounts for 3% of global greenhouse gas emissions. Despite growing pressure, the aging global fleet is renewing slowly due to high costs, uncertainty over future fuels and low ship scrapping rates.

In 2023, the global fleet grew by 3.4%, surpassing trade growth but still below historical averages. Total cargo capacity reached 2.4 billion tons. Growth was driven primarily by container ships and liquefied natural gas (LNG) carriers, though bulk carriers and oil tankers continue to hold the largest share.

By early 2024, only 14% of new tonnage was alternative fuel-ready, with 50% fuel-capable. Failure to accelerate decarbonization could lead to higher costs, regulatory penalties and a loss of competitiveness as markets increasingly prioritize sustainability.

Global shipbuilding trends also influence fleet renewal. In 2023, China, Japan and the Republic of Korea dominated the market. They produced 95% of the global output, with China delivering over half of the world’s capacity for the first time.

In 2023, container ship port calls hit record levels, with major ports like Singapore experiencing nearly double the waiting times due to rerouted vessels and rising shipping volumes.

Digitalization – through blockchain, artificial intelligence (AI) and automation – is key to improving port operations. Ports that have adopted these technologies report reduced waiting times, better cargo tracking and more efficient transshipment.

Asia is leading the way, with the region’s ports making significant strides in digital port management. Handling over 63% of global container port calls, they have maintained efficiency thanks to technological advancements.

Africa is pursuing important port and trade facilitation reforms. East African initiatives, like investments in dry ports in Ethiopia and Kenya, are reducing congestion and improving trade flows.

Caribbean ports face high operational costs and outdated infrastructure, which drive up expenses, reduce their competitiveness in global trade and leave them even more vulnerable to climate risks.

As climate change intensifies, the growing risks of damage, disruption and delay to port and shipping infrastructure and operations – along with implications for safety and contractual rights and obligations – need to be assessed and addressed before such risks and losses materialize. Doing so is important to minimize losses and legal disputes and keep trade flowing and insurance affordable.
