Why 'Capesize'
Capesize bulk carriers are roughly 150,000 to 220,000+ dwt - too large to transit the Panama Canal in most configurations and historically too large for a laden Suez transit, which meant Capesize voyages routed around the Cape of Good Hope or Cape Horn. Canal expansions have changed some of that routing calculus, but the name and the size class persist.
What moves on Capesize
| Cargo | Typical route |
|---|---|
| Iron ore | Brazil-China, Australia-China |
| Coal (thermal and coking) | Australia-Asia, Indonesia-Asia, occasionally Atlantic-Asia |
| Other bulk (minor) | Grain and bauxite cargoes in some periods, but a small share |
Iron ore and coal together account for the overwhelming majority of Capesize cargo, which makes the segment's freight market unusually sensitive to Chinese steel production and power-sector coal demand relative to other dry bulk classes.
The C5 benchmark and rate quotation
Capesize freight is most commonly referenced against the C5 route - West Australia to Qingdao, China - a high-volume iron ore corridor that serves as the industry's headline Capesize benchmark, quoted in US dollars per tonne rather than Worldscale. The Baltic Exchange publishes daily assessments across a basket of Capesize routes including C5.
- C5 (Australia-China) is the most quoted single Capesize route.
- Time charter equivalent (TCE) figures translate voyage economics into an implied daily rate, allowing comparison against period time charter levels.
- Capesize rates are structurally more volatile than smaller dry bulk classes given the concentration in two commodities and two main origin regions.
Frequently asked questions
What is the deadweight range for a Capesize vessel?
Roughly 150,000 to 220,000-plus deadweight tonnes, with the majority of the modern fleet concentrated around 180,000 dwt.
What is the C5 route?
The Baltic Exchange's benchmark Capesize route from Western Australia to Qingdao, China - a major iron ore corridor and the most widely quoted single Capesize freight assessment.
Why is Capesize freight more volatile than other dry bulk classes?
Because the segment's cargo base is heavily concentrated in iron ore and coal from a small number of origin regions, so demand swings in Chinese steel or power generation move the whole market rather than being absorbed across a more diversified cargo base.
