The 10-Year U.S. Treasury yield has risen to 5.0%, up from 4.31%1. Japan's 10-Year Government Bond yield moved to 2.641% from 2.478%1. The coordinated climb across two of the world's most watched benchmarks signals a broad global repricing of capital.
Higher risk-free rates compress the present value of future cash flows. For high-multiple AI and tech companies—where valuations depend on earnings projected years out—the discount rate math is punishing. A 10-year yield at 5.0% versus 4.31% shifts the calculus on every long-duration growth asset.
AI infrastructure is particularly exposed. Data centers, compute facilities, and chip fabrication are capital-intensive, funded through debt markets. New debt issuances in H2 2026 will likely carry higher coupon rates than comparable deals struck in 2024 and 2025. The cost of building out AI capacity rises in step with benchmark yields.
The Japan move reinforces the global nature of this shift. Japanese Government Bond yields were anchored near zero for years, underpinning global carry trades and suppressing borrowing costs internationally. A rise from 2.478% to 2.641%1 is modest in basis points but signals continued normalization by the Bank of Japan—removing a structural source of cheap global liquidity.
Corporate treasuries are already repositioning. Birkenstock's $250 million accelerated share repurchase, executed with Goldman Sachs1, illustrates a broader pattern: in a higher-rate environment, companies favor capital returns over long-duration investment bets.
For credit markets, the transmission is direct. Lending rates tied to Treasury benchmarks rise in lockstep with yields. Investment-grade issuers face higher all-in borrowing costs; high-yield borrowers face tighter conditions as base rates climb. Leveraged buyouts, structurally dependent on cheap debt, become harder to underwrite profitably above 5.0% on the risk-free rate.
For equity investors, the valuation reset is already underway. Enterprise value-to-revenue multiples that AI infrastructure companies commanded in 2024 and early 2025 were priced against a lower discount rate. At 5.0% on the 10-year, those multiples face sustained downward pressure through the balance of 2026.
The bond market has repriced. AI infrastructure—among the most capital-intensive buildouts in recent memory—is directly in the line of fire.
