The yield on 30-year U.S. Treasury bonds hit 5.327 percent on Tuesday, The Daily Beast reported, citing Reuters (Aug. 18, 2026), a session peak described as the highest since 2007. This was an intraday observation rather than an official daily close, and it followed late-July readings that had already moved into the mid-5% range.
