Global Bond Yields Surge as Higher Capital Costs Threaten Western Mine-to-Magnet Buildout

Highlights

• Rising U.S., Japanese, British, and German sovereign yields are pushing project discount rates higher, crushing NPVs for development-stage critical mineral projects.
• Mine-to-magnet projects face compounded risk: large upfront CAPEX, long construction timelines, uncertain commodity prices, and technical ramp-up challenges.
• Higher risk-free rates may render marginal rare earth separation and magnet projects unfinanceable without any change in underlying geology or production assumptions.
• Western governments may need to deploy low-cost loans, loan guarantees, price floors, and equity investment to counter China's patient state-capital advantage.
• Elevated capital costs risk becoming a new critical-minerals choke point, threatening the strategic independence Washington and allies are racing to achieve.
