The Global Aluminium Supply Squeeze

In this episode, Argus examines the intensifying supply squeeze in global aluminium markets following the outbreak of the US-Iran war and the closure of the Strait of Hormuz.

Our experts explore how trade flows, premiums and secondary markets are responding, and why tightness may persist through the remainder of 2026.
