Tropical Cyclone Christine, a category three storm which reached the Pilbara region of Australia late Monday forcing the closure of iron ore mines and halting shipments caused only minor infrastructure damage.
The port handled a near-record 22.3 million tonnes of cargo in November which was also a 37% increase over the year before.
Rio Tinto (LON:RIO), number two iron ore miner behind Brazil's Vale (NYSE:VALE), which is ramping up its annual capacity to 290 million tonnes, exports via the Dampier and Cape Lambert terminals north of Port Hedland.
China consumes close to 70% of the 1.1 billion tonne global trade, half of which is exported from Australia. Iron ore is the world's number two seaborne commodity trade after crude oil.
The benchmark CFR import price of 62% iron ore fines at China's Tianjin jumped to $134.20 a tonne in anticipation of the weather disruption. The raw material is up sharply since hitting lows of $110.40 a tonne in May last year according to data supplied by The Steel Index.
The Sydney Morning Herald reports that the impact of the cyclone on a longer term basis would in all likelihood be negligible:
“Cyclones in the Pilbara are part of what happens and disruption to shipping is built in to market expectations at this time of year,” Ric Spooner, a chief analyst at CMC Markets in Sydney, said by phone. “To be more concerned, the market would need to see a more protracted delay to shipments and production, or serious damage to infrastructure.”
