The U.S. 10-year Treasury yield reached 5.0%, up from 4.31%1. Simultaneously, Japan's 10-year Government Bond yield rose to 2.641% from 2.478%1. Two of the world's largest bond markets moved in the same direction—a signal of broad global capital repricing.
For AI infrastructure, the timing is difficult. Data centers, chip fabrication plants, and compute facilities are capital-intensive. They rely on debt markets. New issuances in H2 2026 will carry higher coupons than deals struck in 2024 or 2025.
The Japan move carries particular global weight. For years, near-zero JGB yields anchored carry trades worldwide—suppressing borrowing costs from Frankfurt to Singapore. The Bank of Japan's ongoing normalization removes a structural source of cheap global liquidity. The ripple effect reaches emerging market borrowers most acutely.
Higher risk-free rates compress the present value of future cash flows. AI and tech companies trade on earnings projected years out. A 10-year yield at 5.0% versus 4.31% shifts the valuation math on every long-duration growth asset, regardless of where those companies are listed.
Corporate behavior is already adjusting. Birkenstock's $250 million accelerated share repurchase, executed with Goldman Sachs1, reflects a wider pattern: in a higher-rate world, capital returns beat long-duration investment bets. European and Asian multinationals face the same calculus.
Credit markets transmit the shock directly. Investment-grade issuers face higher all-in borrowing costs. High-yield borrowers face tighter conditions. Leveraged buyouts—structurally dependent on cheap debt—become harder to underwrite profitably with a 5.0% risk-free floor.
Enterprise value-to-revenue multiples that AI infrastructure companies commanded in 2024 were priced against a lower discount rate. At 5.0% on the 10-year, those multiples face sustained downward pressure. The repricing is not a U.S. story. It is a global one.
