Dynamic spillovers and dependencies between iron ore prices, industry bond yields, and steel prices

Abstract

We examine the spillovers and dependencies between iron ore prices, bond yields of mechanical equipment, infrastructure construction and housing, and car industries, and steel prices by using the spillover index and copula model over the period 2011–2021. Our results show that compared with bond yields, iron ore prices are primary contributors of price spillovers and highly comparable with China's steel prices. Notably, the magnitudes of correlations and risk transmissions from bond yields of related industries to steel prices shifts over the period before the implementation of China's policy to cut overcapacity in steelmaking, after the policy implementation and before the outbreak of coronavirus, and after the outbreak of coronavirus. Because of high price spillovers from iron ore to steel prices and iron ore-steel relationship, policymakers in the steel industry should consider more supply-side policies to mitigate market risks. Meanwhile, risk-averse investors should increase the share of bonds of related industries.
