Simandou’s iron ore project is about more than production volumes. Its ramp-up could also alter shipping balances by increasing distances traveled by ore cargoes. According to a Fearnley Securities estimate reported on October 22, full-scale operations could add 9–10% to global dry bulk tonne-mile demand, all else being equal.
This projection rests on an important geographical difference: Guinea is farther from major Asian steelmaking centers than Australia, currently one of China’s main iron ore suppliers. For the same volume, a Guinean cargo therefore occupies a vessel longer. For shipowners, distance traveled matters as much as tonnage; for exporters, it influences costs and competitiveness.
A faster ramp-up than expected
Volumes observed in 2026 are shaping expectations. Fearnley Securities analyst Fredrik Dybwad estimates that Simandou shipments reportedly reached 19.3 million tonnes year to date. This already approaches MySteel’s annual forecast of 20 million tonnes. The observed pace would correspond to an annualized rate of around 63 million tonnes, without implying that this pace can last twelve months.
Fearnley expects the project could reach its planned nameplate capacity of 120 million tonnes annually in 2028, nearly two years earlier than some market expectations. This date remains a projection. Moving from an annualized pace to steady production will depend on mines opening progressively, train availability, port capacity and coordination among operators.
Between October 5 and 11, the project’s two operators reportedly produced a combined 1.14 million tonnes of ore. The Baowu Winning Simandou consortium accounted for 936,494 tonnes and SimFer for 207,975 tonnes. These weekly figures indicate recent activity, but do not establish a stable average or confirm that planned capacity has been reached.
The logistics corridor at the heart of the equation
Simandou is both a mining and logistics undertaking. Its system comprises two mining operations, more than 600 kilometers of railway and port facilities designed to enable exports of up to 120 million tonnes annually. The challenge is making these components work as one chain: extraction, train loading, transport, storage, transshipment and vessel loading.
This chain will determine the actual export profile. Delays at one link can slow the entire system even if mining capacity is available. Conversely, regular rail and port operations will allow volumes to increase without each stage becoming a bottleneck. The rapid ramp-up announced by analysts must therefore be assessed against operational performance, not production targets alone.
The corridor is also a major infrastructure asset for Guinea. Its economic value will depend on more than exported ore revenues: infrastructure reliability, transport costs, operator access and local benefits will influence its development contribution. For now, available data mainly describes its export function; any broader use must be distinguished from capacity actually contracted.
Why tonne-miles interest the market
A shipping market can tighten without strong growth in global ore demand. If cargoes travel farther, vessels remain occupied longer transporting the same quantity of material. Tonne-miles capture this mechanism. Fearnley’s estimate therefore suggests that Simandou could support dry bulk activity through its relative distance from Asian markets, alongside the additional tonnage it supplies.
Large-capacity vessels, particularly Newcastlemax and Capesize ships, would be affected first. Higher demand for these vessels can spread to smaller segments if large bulk carriers become scarcer or flows are reorganized. However, this transmission is not automatic: it depends on fleet availability, other cargoes, routes and choices among ports.
The projection must also be compared with vessel supply. Planned bulk carrier fleet growth through 2028 is estimated at around 9.3%. If Simandou volumes occupy capacity equivalent to 9–10% additional tonne-mile demand, they could absorb a substantial share of this growth. But this is not an automatic freight rate forecast: vessels are not all interchangeable, and demand for other commodities can accelerate or offset the pressure.
Forward rates do not guarantee revenues
Capesize freight futures already reflect market expectations while remaining volatile. Forward freight agreements cited for the five main routes stood at around $33,000 per day for October, $35,000 for November and $36,000 for December. Contracts for 2027 were around $31,800 per day, compared with Fearnley’s annual estimate of $30,000.
These benchmarks guarantee neither rates actually agreed by individual shipowners nor revenues Simandou will generate. Futures aggregate expectations and can change rapidly with market conditions. Potential demand growth must also be assessed alongside operating costs, port waiting times and backhaul cargoes.
A new benchmark for iron ore trade
Simandou could become a major new ore source for international markets while adding a logistics factor to the global equation. Its shipping contribution will depend on actual shipment growth and the distance between Guinea and end buyers. This is why initial production and transport data is closely monitored by traders and shipowners alike.
The path toward 120 million tonnes annually in 2028 remains ambitious. It will need confirmation through sustained volume growth, a reliable rail and port chain and lasting coordination between the two operators. If these conditions are met, the project could redistribute some ore flows and support long-distance shipping demand. For Guinea, the challenge will be converting this logistics ramp-up into lasting economic benefits beyond export volumes alone.
