Iron ore giants increase mining speed prices continue to climb steel manufacturers suffer
The world's largest iron ore mining companies have achieved the highest production speeds and rising product prices, which has allowed the iron ore price increase that began in the second half of 2010 to be maintained. Iron and steel manufacturers, the main buyer of seaborne iron ore, have to swallow their voices and will remind in their future financial reports that their profit margins will be squeezed by raw material prices for most of 2011. Posco, the world's third-largest steelmaker by sales, said this month that its fourth-quarter 2010 profit fell 60% year-on-year, in part because of soaring iron ore and coal prices, which are producing steel. The two main raw materials. Posco said that the price of iron ore rose by 8% and is expected to continue to climb. Zheng Junyang, the company's chief executive, said that raw material price increases are expected, but it is difficult for us to fully add the rising costs to the product price. Another iron ore importer, Nippon Steel Corp., will release earnings next week. The company is also expected to say that profits are dragged down by rising iron ore prices. At the same time, the world's largest iron ore mining company Rio Tinto, Brazil's Vale and BHP Billiton said they are mining iron ore. Iron ore is one of the most profitable products of these companies. Rio Tinto's global iron ore business reached a new high in the fourth quarter, reaching 65 million metric tons, with an annual output of 239 million metric tons, the same as history, up 3% and 9% respectively. BHP Billiton said that the company's iron ore output in the fourth quarter increased by 4%. The Platts index shows that iron ore prices are currently hovering around $186 per metric ton, a two-year high that was seen in April 2010. Vale has raised iron ore prices by about 7% this month. BHP Billiton is trying to further break even by relying on quarterly index prices, rather than selling more iron ore in accordance with current supply and demand. In fact, BHP Billiton wants to accurately price iron ore when customers need it. BHP Billiton Chief Executive Marius Kloppers told analysts last year that we want all of our products to have a market price on the day, because we believe price transparency is good for both consumers and producers. At present, about 90% of BHP Billiton's production has short-term prices. Steel producers expect raw material prices to continue to rise, so they are trying to raise prices to offset the negative impact of rising raw material prices. China Baoshan Iron & Steel Co., Ltd., the world's second largest steel company, has announced a price increase of 3% to 7% for certain key products. The price of HRC in North America has increased significantly since November last year, with an increase of around 20%. Hot rolled coil is a basic steel product. More companies are expected to announce price increases, but their ability to maintain after price increases will depend on supply and demand in specific regions. It is expected that the steel products in Brazil and China will maintain the price after the price increase, because the demand for steel products in these two countries is relatively strong. But in places like South Korea and North America, price increases may not be as successful. US steel companies are currently producing at 70% or 75% capacity. Although it can be profitable in this case, it shows that demand is not strong.
