US launches pact for AI supply chains to face China

The United States unveiled a pact called “Pax Silica” with Japan, South Korea, Singapore, Australia and Israel to secure supply chains for minerals critical to artificial intelligence and reduce dependence on China, which currently mines about 70% of key rare earths. The agreement — whose practical measures were left vague — seeks to shift from "just-in-time" to strategically aligned sourcing so participants have reliable access to inputs and infrastructure that determine AI competitiveness; the UAE, Canada, the Netherlands and the EU attended discussions but did not formally join. The initiative underscores Washington’s effort to counter China’s resource dominance even as it has simultaneously relaxed export controls by allowing Nvidia AI chip sales to China, reflecting a nuanced mix of competition and engagement.

Analysis

The United States announced a pact branded "Pax Silica" with Japan, South Korea, Singapore, Australia and Israel to secure supply chains for minerals critical to artificial intelligence, explicitly aiming to reduce dependence on China, which currently mines about 70% of key rare earths. The meetings in Washington included the UAE, Canada, the Netherlands and the European Union as observers, and the U.S. signaled other countries may join, but the public statement conceded practical measures were vague.

State Department undersecretary Jacob Helberg framed the initiative as a shift from "just in time" sourcing to strategically aligned supply chains, implying coordinated policy, investment and infrastructure actions over time; however, the lack of detail creates execution and timing risk for markets. The initiative targets inputs and infrastructure that determine AI competitiveness, suggesting potential long-term demand for non-Chinese miners, processors and logistics tied to allied jurisdictions.

The announcement coincides with a U.S. decision to allow exports of Nvidia's advanced AI chips to China, creating a near-term commercial upside for NVDA while the Pax Silica pact signals a longer-horizon geopolitical strategy to diversify raw-material sources. Investors should therefore separate the immediate revenue implications for chip vendors from the slower, policy-driven reconfiguration of mineral supply chains, and monitor for concrete trade, financing or industrial actions that would move commodity and supplier equities.

Key Decisions for Investors

• Monitor official Pax Silica implementation details (funding, procurement commitments, joint investments or trade measures) before materially increasing exposure to rare-earth miners or processors, as the pact is currently vague
• Consider modest, targeted long-term exposure to miners, processors and supply-chain service providers in allied countries that stand to benefit from diversification away from China, while awaiting confirmed capital plans and timelines
• For Nvidia (NVDA), recognize the near-term revenue upside from the U.S. decision to allow advanced AI chip exports to China and consider holding or selectively adding exposure, but implement hedges or position limits to protect against future export-policy reversals or geopolitical escalation
• Use option hedges or reduced position sizing to mitigate execution and geopolitical risk, and watch commodity price moves, government procurement announcements and bilateral agreements as triggers to increase or trim positions
