Jan. 7, 2026 - Bauxite is set to remain a key support for the capesize freight market into 2026, underpinned by sustained Chinese demand and strong export momentum from Guinea, even as longer term supply risks begin to surface.

According to Signal Ocean’s Commodity Radar report, bauxite exports from Guinea are up 22% year-to-date, helping offset weaker coal volumes and stabilise tonne-mile demand. 

Total bauxite flows in 2025 sit 18% above 2024, with China accounting for all incremental demand, lifting imports 22% year-on-year. Elsewhere, imports have remained broadly flat.

Guinea’s export growth has been uninterrupted throughout 2025 and is on track to reach about 175 million tonnes, making bauxite the strongest capesize commodity behind iron ore. The country now supplies roughly 69% of global bauxite exports, compared with 18% for Australia. 

While production volumes are closer – about 130 million tonnes versus 100 million tonnes – Australia processes much of its output into alumina, whereas Guinea exports most of its bauxite.

Further ahead, Guinea’s plans to develop around 7 million tonnes a year of alumina capacity by 2030 could divert about 14 million tonnes of bauxite from export markets. While the initial impact would be modest, expanded domestic processing could gradually tighten seaborne supply and weigh on capesize demand over time.

For now, bauxite remains a key pillar of the capesize outlook. Although the first quarter is typically seasonally weaker, Q1 2026 shipments are expected to exceed last year’s levels before strengthening into Q2, reinforcing bauxite’s role as a stabilising force in bulk shipping markets.

Bauxite builds for 2026
Signal Ocean latest data aligns with other companies and analysts expectations for bauxite in 2026, according to a report on the twelfth day of Christmas that the demand for traded bauxite in the Asia-Pacific region has been rising double digits over four years. 

Metro Mining recently announced its plans to further increase bauxite volumes in 2026, through debottlenecking at the Bauxite Hills Mine in Far North Queensland. 

CEO Simon Wensley previously said that within the company’s expansion fully in place, “investors can expect a strong finish to the year”, as well as an increase of shipments totalling 6.5 million tonnes of bauxite. 

“With current geopolitical background, Metro’s market reputation and offtake agreements with our established customers significantly de-risks uncertainty and provides a secure investment for our shareholders,” Wensley said. 

In 2025, Metro achieved new records of bauxite shipments, as in August, the company increased production rate by 6% – totalling 753,101 wet metric tonnes, as reported.  

In July, Metro shipped 714,000 wet metric tonnes of product from Bauxite Hills, while in June 2025, 589,000 wet metric tonnes were shipped. 

Bauxite Hills has been operating since April 2018 and as of the end of 2024 had an estimated reserve of 77.7 million tonnes and a resource of 114.4 million tonnes.

The mine employs more than 300 people and in 2022 exceeded its Traditional Owner employment target of 30% and maintained an indigenous workforce of 35%.

Bauxite, the sole raw material used to produce primary aluminium, is a metal that surrounds the modern world more than realised.

According to CRU International, aluminium demand is forecast to grow by 33.3 million tonnes in the following decade, as of 2020, to 119.5 million tonnes in 2030.

The transition towards green energy sources strengthens the sector’s demand for aluminium – making it reach 15.6 million tonnes in 2030. China alone is expected to deliver 47% of that growth, as reported by CRU.
