Silica differential in iron ore prices jumps on supply glut

摘要

Singapore—Increasing supply of Brazilian fines and Chinese concentrates has pushed down premium for high-silica cargoes, market sources said this week, leading to widening silica differentials. The silica differential in the iron ore price is the discount buyers get when silica content, an impurity, rises above 4%. S&P Global Platts assessed 1% silica differential for 60%-63.5% Fe cargoes containing 4.5%-6.5% silica at $1.60/dry mt Tuesday, which is the highest level since May 2018.
