30-Year Treasury Yield at 5.216% Raises Financing Bar for AI Data Centers and Semiconductor Fabs

The US Treasury sold $25 billion in 30-year bonds on August 13, 2026, at a 5.216% yield — the highest since 2001, per Bloomberg and the Financial Times. With the 30-year risk-free rate above 5%, discount rates anchoring long-duration tech infrastructure — AI data centers, grid modernization, semiconductor fabrication — shift upward, raising the IRR hurdle for multi-decade capital projects.
