[Rio Tinto to Expand Amrun Bauxite Mine to Secure Long-Term Supply]

Rio Tinto will commence early works and finalize engineering studies to expand bauxite production at its Amrun mine in Queensland’s Cape York Peninsula, targeting first output from the new development by 2029. The Kangwinan project—named in consultation with the Wik Waya Traditional Owners—will involve constructing a new mine and expanding the existing Amrun port to nearly double production from the Weipa Southern operations, increasing capacity by up to 20 million tonnes annually on top of the current 23 million tonnes.

The expansion is intended to offset declining output from the Andoom and Gove mines, both expected to close by decade’s end. A final investment decision is scheduled for 2026, contingent on cultural heritage and environmental assessments and regulatory approvals. Early works approved include a 250-room workers’ camp and initial road access. The project is expected to support over 800 construction jobs and retain the existing workforce in the region, ensuring continued supply to Rio Tinto’s Australian refineries and export markets.

Fed to Keep Large Banks' Capital Levels Unchanged, Postpones Stress Test Reforms Until 2027

The US Fed has announced that it will maintain the capital levels of large banks unchanged during the upcoming stress test cycle (corresponding to the 2026 cycle). At the same time, the US Fed is planning multidimensional reforms to this annual test, aiming to enhance its transparency. The US Fed's Vice Chair for Supervision, Bowman, revealed that adjustments to the stress capital buffer requirements for large banks will be postponed until 2027. This move is intended to provide the US Fed with sufficient time to evaluate potential flaws that may be exposed in its testing models when assessing banks' financial conditions under simulated economic downturn scenarios.
