Rio Tinto, one of the world’s largest iron ore producers, is facing fresh logistical challenges as two tropical cyclones off the coast of Western Australia disrupt port operations. The company has begun clearing iron ore vessels from Cape Lambert and Dampier ports in response to heightened sea swells caused by Tropical Cyclone Taliah and Tropical Cyclone Vince.

Impact on Operations

The precautionary move comes amid ongoing recovery efforts from damage caused by Tropical Cyclone Sean in January. Heavy rainfall and flooding from the previous storm had already impacted Rio Tinto’s rail operations and infrastructure, particularly at the East Intercourse dumper. The additional disruptions caused by the latest cyclones are exacerbating supply chain challenges with high stock levels further complicating port logistics.

The Western Australian cyclone season typically lasts from November to April, and severe weather events can significantly impact the shipping industry. Analysts suggest that the damage caused by Cyclone Sean was more severe than initially expected, as repair efforts have stretched beyond the usual one-to-two-week timeframe. RBC Capital Markets analyst Kaan Peker noted that if repairs continue beyond three to four weeks, Rio Tinto may struggle to meet its annual production guidance.

Market Implications

Despite the disruptions, Rio Tinto has maintained its production target of 323 million to 338 million metric tons of iron ore for 2025, compared to 328.6 million tons produced last year. However, continued logistical delays could introduce risks to these projections.

From a market perspective, the ongoing shipping challenges could lead to a risk premium on iron ore prices. Chinese steel manufacturers, who did not stockpile large reserves ahead of the Lunar New Year, are expected to resume operations soon, increasing demand for iron ore. Futures prices have already seen an uptick, rising to approximately $105 per ton from three-month lows of $97 per ton in January.

Comparative Stability at Port Hedland

While Rio Tinto’s ports are facing disruptions, Port Hedland, Australia’s largest iron ore export hub used by BHP, Fortescue, and Hancock Prospecting, has not been cleared due to the latest cyclones. This highlights the geographical impact of these weather systems and the relative resilience of other key shipping hubs.

Australia’s weather bureau predicts that Tropical Cyclone Taliah will remain a severe tropical cyclone in the coming days, but it is expected to stay well away from the Western Australian coast. While this offers some relief, the full extent of the disruption to Rio Tinto’s shipments will likely be clearer after the company provides an update in its full-year results announcement on February 19.

The situation underscores the vulnerability of global commodity supply chains to extreme weather events, emphasizing the importance of risk management strategies in the mining and shipping sectors.
