The 10-year Treasury yield closed at approximately 5.163–5.17% on September 25, 2026, near its highest level since June 2007, while the 30-year yield reached 5.47–5.49%, approaching 2004 levels. [1][2]
On September 24, the 10-year yield hit 5.21%, its highest in 19 years, surpassing the September 18 high of 5.01%, and the 30-year yield reached its highest level since 2004. [3][4]
Earlier in September, the 10-year yield crossed 5% on September 15 for the first time since July 2007, reaching an intraday high of 5.041% before settling at 5.016% post-FOMC, and was recorded at 5.016% on September 16 post-FOMC. [5][6]
The 2-year yield was approximately 4.70% on September 16 and 4.68% on September 15, while the 20-year yield auctioned on September 15 achieved 5.42%, the highest since January 1986. [7][8][9]
By September 11, the 10-year yield had surged from ~4.78% in early September to near 5%, closing at ~4.97%, driven by hot CPI data, a Saudi pipeline attack, and post-ECB global tightening read-through. [10][11][12]
Watch for continued upward pressure if inflation remains persistent, Fed policy stays hawkish, fiscal concerns intensify, or global bond markets tighten further, as these were key drivers of the September surge. [13][14][15][16]
