West Africa's mineral export boom will need the equivalent of another 120 capesizes by 2030, UK consultancy Tradeviews forecasts, as regional shipments surge 50% from 2025 levels to 303m tonnes by the end of the decade.

Guinea's Simandou iron ore project leads the charge. The maths matters for shipowners: a capesize round voyage between Guinea and China takes roughly 78 days, against just 29 days on the Australia-China route. Moving a tonne from West Africa absorbs around 2.6 times as much vessel time, Tradeviews calculates.

On that basis, the consultancy estimates West African trades will require the equivalent of 330 capesizes by 2030, up from 210 last year.

"West Africa looks set to remain the fastest growing long-haul source of dry bulk cargo," Tradeviews stated in its new report.

How fast is the growth running now?

The boom is not a projection. It's already visible in the flows.

• The five West African exporters covered by Tradeviews shipped 160.1m tonnes in their principal trades in the first eight months of this year, up 25% year on year.
• Liberian iron ore exports nearly doubled to 10.1m tonnes.
• Tradeviews expects regional exports to reach 267m tonnes next year.
• Guinean iron ore shipments should climb to 45m tonnes in 2027 and roughly 112m tonnes by 2030.

Bauxite runs the other way. Exports are forecast to retreat from a peak of nearly 194m tonnes this year to 153m tonnes by 2030, as Guinea pushes ahead with domestic alumina processing.

Where does freight bite?

High rates have already squeezed marginal miners out of the market. BRS Shipbrokers noted in its latest weekly report that exceptionally high freight had priced some higher-cost Guinean bauxite miners out of exports entirely.

Guinea shipped 15.61m tonnes of bauxite in September, down 12% from August. At one point, freight costs accounted for more than half the delivered value of the commodity.

Relief is coming through falling capesize rates. The C3 benchmark has dropped from $43.43 a tonne in late September to $32.95 on October 12, prompting BRS to suggest Guinean bauxite exports could recover by 5% to 10% month on month in November and December.

The broker calls it a "test of elasticity", not the start of another cargo boom. Shandong alumina refineries processing imported ore lost RMB261.8 per tonne in September, BRS pointed out.

SSY has flagged the same dynamic. Guinean bauxite exports have retreated from early-September highs, and "shipping demand is turning more sensitive to margin levels on the mining side," the broker observed.

How much reaches independent owners?

The catch for the conventional capesize market is who owns the ships doing the hauling.

SSY noted in an August market report that VLOCs above 220,000 dwt accounted for nearly half of Simandou shipments during the first half of 2026. Chinese tonnage makes up nearly 40% of the current VLOC orderbook, SSY data shows — raising questions over how much of Simandou's prospective tonne-mile demand will ever filter through to the capesize spot market.

Tradeviews itself cautions that potential Guinean bauxite export restrictions, Simandou delays, dedicated ore carriers and the displacement of Australian iron ore shipments could all shrink the benefit for the wider capesize fleet. Much of the market, the consultancy notes, increasingly looks like a Chinese conveyor belt.

For capesize owners outside that loop, the tonne-mile story is real but conditional. The trade will grow; the spot market's share of it is the open question.

Bauxite's growing weight in dry bulk gets its own stage at next April's Geneva Dry, the premier commodities shipping conference. The Bauxite Blitz session on April 28 will examine the expanding trade, shifting supply patterns and capesize demand implications, with Torvald Klaveness president and CEO Ernst Meyer and South32's charterer and decarbonisation lead Robert Haggquist confirmed as speakers. Braemar's Derek Langston moderates.
