A port that serves everyone but itself
Roughly one in seven of the world’s shipping containers touches Singapore, and almost none of them are staying. That is the paradox at the heart of the island’s economy: a country of six million people runs one of the two largest container ports on earth not to serve itself but to serve everyone else. In 2025 the Port of Singapore handled 44.66 million twenty-foot equivalent units (TEU), up 8.6% on the year — a record, and the clearest proof that Singapore’s role as the world’s busiest transhipment hub has strengthened rather than faded. Add a record 56.77 million tonnes of marine fuel sold at the bunkering hub, and the picture is of a port operating at the top of its historical range even as global trade wobbles.
The engine of that container throughput is PSA Singapore, whose own terminals crossed 40 million TEU for the first time in 2024 — a milestone for a single operator. The number matters less than what it represents: Singapore is a transhipment port, meaning the overwhelming majority of those boxes arrive on one ship and leave on another, never entering the domestic economy. A container line chooses Singapore because it can reach 600-plus ports across 120-plus countries from a single call, and because the port turns ships around fast enough to keep tight schedules. Lose either and the boxes go elsewhere. Everything Singapore is building is designed to protect both.
PSA and the shift to Tuas Port
The largest bet is physical. Singapore is consolidating its scattered city terminals — Tanjong Pagar, Keppel, Brani, Pasir Panjang — into a single mega-port at Tuas on the island’s western edge, freeing prime waterfront land for redevelopment while building capacity for the century ahead. Tuas Port is the world’s largest fully automated container terminal, and it is being reclaimed from the sea on an epic scale, its wharves formed from giant concrete caissons each roughly the height of a ten-storey building. Its first berths opened in late 2022, and by early 2025 the terminal had passed 10 million TEU cumulatively — a fast ramp for a facility still under construction. When complete in the 2040s, Tuas is designed to handle around 65 million TEU a year, which would make it comfortably the largest container terminal on the planet.
Automation is the differentiator. Tuas runs automated guided vehicles moving containers between quay and yard, automated yard cranes, and remotely operated quay cranes, coordinated by a control system that plans vessel and yard moves in software rather than by radio and clipboard. The point is not to remove people — PSA is retraining thousands of workers into control-room and engineering roles — but to lift throughput per metre of quay and per hectare of yard, because in Singapore land is the scarcest input of all. A conventional terminal cannot double its footprint; an automated one can double the work it extracts from the footprint it has.
Air cargo at Changi
Sea is only half the freight story. Changi Airport handled 1.99 million tonnes of airfreight in 2024, cementing its place among the world’s major air-cargo hubs and complementing the seaport with speed for the goods that cannot wait — semiconductors, pharmaceuticals, perishables, e-commerce parcels and aircraft spares. Air cargo is a small share of tonnage but a large share of value, and it plugs Singapore into the high-margin end of global supply chains. The airport’s fifth terminal and expanded freight facilities are being built to grow that capacity, and the industrial layer it supports — temperature-controlled airside handling, pharma cold-chain, ground-handling equipment — overlaps closely with what the seaport demands.
Bunkering and the green-fuel transition
Singapore is not only where cargo changes ships — it is where the world’s ships refuel. It is the largest bunkering hub on earth, and 2025 set a record: 56.77 million tonnes of marine fuel sold, up 3.4% on the year. That scale gives Singapore rare leverage over how shipping decarbonises, because a fuel that is not available in Singapore is, for practical purposes, not available to the global fleet. The transition is now measurable: sales of alternative marine fuels reached roughly 1.95 million tonnes in 2025, up sharply from 1.35 million in 2024 — still a small share of the total, but growing fast. Methanol, biofuel blends, LNG and, in pilot form, ammonia are all now being bunkered, and the Maritime and Port Authority (MPA) has run first-of-their-kind ship-to-ship transfers to prove the operational chain works. Singapore intends to own the green-fuel transition the way it owns conventional bunkering — by being first to have the fuel, the standards and the storage in place, so that when the fleet switches, it switches through Singapore.
The industrial layer Singapore Industry Index tracks
Behind the throughput headlines sits an industrial economy that most cargo never sees. A modern port and its hinterland warehouses run on materials-handling equipment: automated guided vehicles and autonomous mobile robots, forklifts and reach stackers, conveyors and sortation systems. As warehouses go vertical and automated, racking and warehouse-automation systems become a distinct engineering market with local integrators. Cold-chain is a specialism of its own: refrigerated warehousing and reefer handling for food, pharmaceuticals and chemicals, where a temperature excursion can destroy a shipment’s value. Packaging, palletising and end-of-line automation sit alongside. These are precisely the capabilities Singapore Industry Index exists to record — the companies that build, install and maintain the physical machinery of logistics.
Supply-chain management, 3PLs and resilience
Above the hardware sits the intelligence layer: third-party logistics providers (3PLs), freight forwarders, customs brokers and supply-chain managers who orchestrate the movement of goods across the region. Singapore is the regional headquarters of choice for global logistics firms, valued for the same reasons the port is — connectivity, rule of law, talent and neutrality. That last quality has grown more valuable. As multinationals pursue “China-plus-one” strategies, spreading manufacturing across Vietnam, Malaysia, Indonesia, Thailand and India, Singapore benefits as the coordinating node: someone has to knit a more fragmented, multi-country supply chain together, and Singapore is the natural place to do it.
Resilience and outlook
None of this is guaranteed. The port’s advantage rests on volumes that rivals could, in principle, capture — regional ports are expanding, and shipping alliances reshuffle networks in ways that move millions of boxes at a stroke. Singapore’s defence is to stay the most efficient, most connected and most reliable option by a wide enough margin that switching is not worth the risk — which is exactly what Tuas, the automation, the bunkering leadership and the green-fuel head start are for. The 2040s target of roughly 65 million TEU is not a forecast of demand; it is a statement of intent that Singapore will have the capacity to remain indispensable regardless of how trade patterns shift. For the industrial firms that build the cranes, racks, reefers, robots and bunkering systems underneath it all, the busiest port in the world is also the steadiest customer.
