Iron Ore Port Stocks Hit 3-Year Low as Cyclone Veronica II Shuts Port Hedland for 10 Days
2026-10-24, FP360 — Iron ore port stocks at China's 45 major ports have plunged to a three-year low of 112 million tonnes, down 8.2% week-on-week, after Cyclone Veronica II forced the closure of Port Hedland for 10 days, disrupting 15% of global seaborne supply. The disruption, which halted 2.5 million tonnes per day of exports, has driven the Dalian iron ore futures contract up 12% to 985 yuan per tonne, while the 62% Fe benchmark surged to $145 per dry metric tonne, up 9% since the port closure was announced.
Iron ore prices are poised for further upside as port stocks dwindle and supply fears intensify, with the 62% Fe benchmark targeting $160 per tonne in the near term.
Australian iron ore miners such as BHP, Rio Tinto, and Fortescue could see earnings upgrades as realized prices surge, while Chinese steel mills with locked-in supply may benefit from margin expansion.
Chinese steel producers face margin compression and potential production cuts as raw material costs spike, with rebar and hot-rolled coil margins already down 15% from September levels.

Why Is the Stock Market Down Today? Iron Ore Shock Adds to Inflation Fears
Global equity markets are under pressure today, with the S&P 500 down 1.2% and the ASX 200 falling 1.8%, as the iron ore supply shock reignites inflation concerns and weighs on steel-producing sectors. The shutdown of Port Hedland, the world's largest iron ore export terminal, has removed 25 million tonnes of supply from the market, equivalent to 15% of global seaborne trade, according to estimates from the Australian Bureau of Meteorology and port authorities. This is not merely a commodity story—it feeds directly into steel prices, construction costs, and ultimately consumer inflation, complicating the Federal Reserve's rate path.
Why Is the Stock Market Going Down Today? Cyclone Veronica II Shuts Port Hedland for 10 Days
The immediate cause of today's equity sell-off is the confirmation that Port Hedland will remain closed for 10 days, with Cyclone Veronica II sustaining winds of 220 km/h and causing significant damage to loading infrastructure. The port, which handles 500 million tonnes of iron ore annually, has not seen a closure of this magnitude since 2019. According to the Pilbara Ports Authority, all berths are out of action, and ships are being diverted to Dampier and Cape Lambert, but those ports lack the capacity to absorb the 2.5 million tonnes per day that normally flow through Hedland. The disruption has already pushed the 62% Fe iron ore benchmark to $145 per dry metric tonne, up 9% since the closure announcement, while the Dalian Commodity Exchange's most-active iron ore contract jumped 12% to 985 yuan per tonne.
The Stock Market Today Chart: Iron Ore Miners Surge, Steelmakers Slump
The stock market today chart shows a clear divergence: iron ore miners are soaring while steel producers are slumping. BHP Group (BHP.AX) is up 4.5% in Sydney trading, Rio Tinto (RIO.AX) has gained 3.8%, and Fortescue Metals (FMG.AX) is up 6.2%. In contrast, Chinese steelmakers are under pressure, with Baoshan Iron & Steel (600019.SS) down 2.3% and Ansteel (000898.SZ) falling 1.9%. The supply shock is also evident in freight rates, with the Baltic Capesize Index surging 18% as ships are forced to wait or divert. Port stocks at China's 45 major ports have fallen to 112 million tonnes, down 8.2% week-on-week, the lowest level in three years, according to Mysteel data.
Market Impact: Iron Ore Port Stocks at 3-Year Low, Supply Chain Contagion
The 10-day closure of Port Hedland is a significant supply shock that will reverberate through the global steel supply chain. With port stocks already at a three-year low, Chinese steel mills will be forced to draw down inventories rapidly, and spot prices could spike further if the closure extends. The Australian Bureau of Meteorology forecasts that Cyclone Veronica II will continue to affect the Pilbara region for at least another 48 hours, and any further delays in reopening the port could push iron ore prices above $160 per tonne. The disruption also comes at a time when Chinese steel demand is recovering, with crude steel output up 3.2% year-on-year in September, adding further upside pressure to prices.
