Just been looking at where the world's iron actually comes from, and the supply picture is way more concentrated than most people realize.

The volatility in iron ore prices over the last few years tells you a lot about global economic stress. We hit over US$220 per ton back in May 2021, then crashed down to US$84.50 by November. China's demand dropped while supply ramped up, and prices tanked. Then 2023 saw a rebound to the US$120-130 range thanks to supply constraints in Australia and Brazil, plus ongoing geopolitical tensions. But 2024 was rough - started at US$144 per ton and slid all the way down to US$91.28 by September as interest rates stayed elevated and China's property sector struggled.

When you look at the actual iron producing countries driving global supply, Australia absolutely dominates with 960 million metric tons of usable ore in 2023. The Pilbara region is basically the heartland of world iron production. BHP, Rio Tinto, and Fortescue are the major players there. Brazil comes in second with 440 million metric tons, mainly from Pará and Minas Gerais states. Vale's Carajas mine is the world's largest single operation.

China's interesting because despite being only the third largest producer at 280 million metric tons, they consume over 70 percent of global seaborne iron ore. Their domestic supply can't touch demand for stainless steel production. India's climbing up the rankings fast - they hit 270 million metric tons in 2023, up from 251 the year before. NMDC is their main producer and they're targeting 60 million MT annually by 2027.

Russia, Iran, Canada, South Africa, Kazakhstan, and Sweden round out the top ten iron producing countries. Russia was hit hard by sanctions though - exports fell from 96 million metric tons to 84.2 million metric tons in 2022. Iran's been ramping up production despite export duties, while Canada's Champion Iron is expanding capacity at Bloom Lake. South Africa's output has actually declined due to transport and logistics problems.

The supply dynamics matter because they directly impact where prices go. Recent Chinese stimulus announcements and Fed rate cuts could support prices, but the structural challenge remains - global iron ore producing countries need to balance supply with weakening demand signals. Worth watching how this plays out over the next couple quarters.
