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.

Late‑July benchmarks and daily prints
The late-July climb is visible in official and contemporaneous readings. The Federal Reserve Bank of St. Louis’ 30-year constant-maturity series (DGS30) shows a daily observation of 5.27 Percent on 2026‑07‑31, according to FRED. Around that stretch, multiple commentaries pegged session levels between 5.20% and 5.24% on July 29–30, with Saxo noting about 5.23% on July 30 and characterizing the area as levels not seen since 2007. Saxo’s note also placed the late-July highs after the Federal Reserve’s July policy decision and related market moves. The 5.27 Percent daily close on July 31 anchors the period’s official record.
