Iron ore rises as freight costs hit five-year high

On the Shanghai Futures Exchange, October 2026 rebar rose 0.58% to 3,102 yuan a tonne, while iron ore futures advanced on both the Dalian Commodity Exchange and the Singapore Exchange, reaching 738 yuan a tonne and $99.50 a tonne, respectively. Iron ore was also trading around 730 yuan a tonne during the session, positioning it for a second straight weekly gain.

The immediate catalyst was the Baltic Dry Index, which jumped 4.7% on Sept. 3 to 3,488, the highest in almost five years. Capesize rates, the key gauge for large bulk carriers that haul iron ore, surged 7.1% to 6,042. Bad weather, higher fuel costs and increased transshipment from Guinea helped push freight higher, while declining iron ore inventories at major Chinese ports added support.

For investors, the setup creates a split between the winners and the vulnerable. Iron ore producers and shipping companies benefit from stronger freight and commodity pricing, while steel mills face a narrower spread if raw-material costs rise faster than finished steel prices. That risk is especially relevant in China, where subdued steel consumption and weak mill profitability could cap further gains in ore and rebar.

The domestic picture in Vietnam remained calmer, with local rebar prices held steady by producers including Hoa Phat, Viet Y and Pomina. That stability suggests the global rally is still being driven more by imported raw-material dynamics than by a broad-based surge in construction demand.

The key question now is whether pre-holiday stocking in China can sustain the rally or whether margin pressure at mills forces restocking to slow. If freight stays elevated and port inventories keep falling, iron ore should remain supported; if steel demand disappoints, the upside may prove limited.
