> The benchmark yield climbed from 5.24% on Wednesday to 5.56% on Monday as rising debt, issuance and hyperscaler borrowing kept long-term rates elevated.

The U.S. 30-year Treasury yield climbed to 5.56% on Monday, Sept. 28, extending a rise in long-term borrowing costs that can weigh on risk assets, including cryptocurrencies.

The benchmark stood at 5.24% on Wednesday, Sept. 23, and 5.49% on Friday, Sept. 25. The Sept. 28 reading was based on indicative bid-side quotations collected near 3:30 p.m. ET (19:30 UTC).

The move continued the trend covered in [TokenPost’s earlier report on the 30-year Treasury yield topping 5.5%](<https://www.tokenpost.com/news/investing/24177>).

The 30-year yield reached 5.31% in August, its highest level since 2007, while remaining above 5% for the longest stretch since that year. Structural pressures include rising U.S. debt, increased Treasury issuance, borrowing by hyperscalers and uncertainty around the neutral policy rate.

Hyperscaler bond issuance rose from $44 billion in 2024 to $160 billion in 2025 and was projected to reach $400 billion in 2026. That increase has added to borrowing demand from large technology infrastructure companies as they fund artificial-intelligence expansion.

The 30-year Treasury yield serves as a benchmark for long-term borrowing costs. Higher yields generally reduce the value of existing long-duration bonds and can increase financing costs for mortgages, corporate debt and government borrowing.

For crypto markets, elevated long-term yields can make fixed-income assets relatively more attractive and tighten financial conditions. That creates a potential headwind for speculative assets by increasing the cost of capital across markets.
