Steel momentum continues, but iron ore supply pressuring prices
Steel mill margins have improved markedly in China, as mills benefit from a number of factors: ongoing demand recovery assisted by seasonality, low steel inventory and a slower production rise than expected have all contributed to continued strength in steel prices. Meanwhile, margins have blown out to highs not seen since May 2015, assisted by a surge in iron ore supply in recent weeks that has pressured iron ore prices lower despite the rise in steel output.
