On July 4, 2025, President Trump signed H.R.1, the One Big Beautiful Bill Act (OBBBA), into law. The sweeping legislation enacts major changes across tax and fiscal policy, social safety-net and healthcare programs, and immigration and border enforcement. Notably, it includes substantial revisions to the Inflation Reduction Act (IRA), rolling back several programs with lasting implications for the energy sector and critical mineral supply chains. While the bill aims to accelerate domestic sourcing of critical minerals and reduce U.S. dependence on China, it simultaneously eliminates key IRA incentives that have been driving downstream demand—introducing new complexities for making long-term minerals investments and reshaping critical mineral supply chains long dominated by Beijing.
